1- Rules of Flow for Product Management: an AirBnB Case Study

“Engagement” is a term that is so overused in product management that it has almost lost its meaning. So often I’ve heard from teams, “We’ll measure the success of this test with engagement,” which could mean anything from feature click-through to bounce to we-aren’t-really-sure-this-will-drive-conversion-so-we’re-hedging-our-bet. Underneath, the reason this term has been co-opted and jargonized is that genuine, productive engagement can be ramped toward long-term customer loyalty. And loyalty pays off: a loyalty increase of 7% can boost lifetime profits per customer by as much as 85%, and a loyalty increase of 3% can correlate to a 10% cost reduction ( Brand Keys ).

3- Netflix Q1 ’21 Subscriber Growth Miss: Can We Avoid Another One?

Sadly I’m not a Netflix employee and will be limited to publicly available data but the wealth of information on the Internet about Netflix is sufficient to generate insights for this case study.

4- Amazon Go Green

As part of the Design Challenge from productdesign.tips, our team came together to find ways for Amazon to encourage more sustainability on their e-commerce platform. As with any unsolicited design project, the challenge comes with a lack of access to application analytics and technical feasibilities. Nonetheless, the question remains: How might we design checkout screens for an e-commerce app to help people recycle the goods they buy?

Quora has become a substantive resource for millions of entrepreneurs and one of the best sources for Business to Business market. Majorly used by writers, scholars, bloggers, investors, consultants, students this Q/A site has much to offer in terms of knowledge sharing, connection building and information gathering.

6- Building a product without any full-time product managers

Jambb is an emerging social platform where creators grow their communities by recognizing and rewarding fans for their support. Currently, creators monetize fan engagement through advertisements, merchandise, and subscriptions, to name a few. However, this only represents 1% of fans, leaving the other 99% (who contribute in non-monetary ways) without the same content, access, and recognition that they deserve.

8- What if you can create Listening Sessions on Spotify

Summary: The project was done as a part of a user experience design challenge given to me by a company. I was given the brief by them to work on a feature of Spotify and I spent around 25–30 hours on the challenge in which I went through the entire process, from the research to testing.

9- Redesigned Apple Maps and replicated an Apple product launch for it

Quick-fire question; what is the single most important and widely used feature in a phone — asides from texting and instant messaging friends, coworkers and family? Maybe you guessed right, perhaps this feature is so integrated into your life that you didn’t even think about it — either way, it is your phone’s GPS. It is reasonable to say that GPS technology has changed society’s lives in ways we never could’ve imagined. Gone are the days of using physically printed maps and almanacks, when we now have smartphones with navigation apps.

Everyone has a preference, and apps have come out to try and address every need.

Here’s why reading product management case studies is a worthwhile investment of your time. A well-written case study:

• Gives you an in-depth understanding of real product problems : Meeting or exceeding the expectations of the customers is always challenging. Whether it is technical complexities, budget limitations, or organizational miscommunication, a case study helps you recognize the source of the problem which led to the development of a less-desirable product.
• Contains practical insights outside of the theory : Even a layman can learn the steps of SaaS product management . However, seasoned product managers know that developing a successful product takes more than learning the development steps. These case studies contain tons of real-life scenarios and the lessons that come with them.
• Educates you and makes you a better product manager: Product management case study examples take you through the journey of developing a product, which helps you improve your existing approach toward product development. You will also learn better ways to manage your team and resources.

In simple terms, a product management case study helps teams learn lessons that they can emulate to develop a more profitable product.

In this article, let’s look at six product management case studies that are a must-read for every product manager.

1. Slack: Initial product launch strategy

Stewart Butterfield started a gaming company called Tiny Speck to change the world of massively multiplayer online role-playing games (MMORPG). Him and his team created Glitch which was quite different from other games in that genre such as World of Warcraft.

Glitch was a 2D game that did not have the violent aspects that typical MMORPG games had at the time. It allowed extensive character personalization and Butterfield described it as “Monty Python crossed with Dr. Seuss on acid”.

While building Glitch, Butterfield and his team used the Internet Relay Chat (IRC), an online chat tool popular in the 80s and 90s. However, it fell short as the team found it difficult to keep track of past conversations, which motivated them to build their own communication tool.

As they developed Glitch, their internal chat tool gained more features based on their needs.

Despite lots of support from investors, Glitch was unable to attract enough players to keep running profitably and Butterfield eventually shut it down in 2012 .

After six months, in early 2013, Butterfield renamed their internal communication tool Slack - acronym for Searchable Log of All Conversation and Knowledge and requested his friends and colleagues to try it out and give feedback — they all loved it.

By May 2013, Slack was ready for the big reveal which posed a new challenge — executing the perfect launch strategy to drive demand.

Slack’s Challenge: Nailing the initial product launch

While launching an app that can have such an impact on how organizations work, it is crucial to get it right. At the time, there weren’t many team messaging apps and most teams had conversations via email.

Slack needed a significant number of early adopters to validate their hypotheses about team collaboration and collect data that will help them improve its services further. Consequently, this increased the stakes for the first launch.

How did Slack do it

CEO Stewart Butterfield revealed that on the first day of the launch, Slack welcomed 8000 new users which rose to 15000 at the end of the second week. The credit for this initial success, he explains, went primarily to social media.

Social media helped Slack deliver its PR pieces through its genuine users. This led to a snowballing effect because people interacted with people.

Slack recorded over 18 million active users in 2020.

Although the impact of social media-based word-of-mouth marketing will have different levels of success as it depends on factors such as the type of product and its use cases, you should have a social media marketing strategy to spread the word.

2. Superhuman: Finding product-market fit

‍ Superhuman is a premium email service for busy teams and professionals who need more of everything; speed, usability, and personalization. Apart from superb design, Superhuman processes and executes any request within 100ms.

Rahul Vohra built Rapportive in 2010 — a plugin that adds social profiles to Gmail which was later acquired by LinkedIn . This gave Vohra an intimate view of email and quickly realized that things will progressively get worse.

In his words, “I could see Gmail getting worse every single year, becoming more cluttered, using more memory, consuming more CPU, slowing down your machine, and still not working properly offline.” 

He also brought attention to the number of plugins people used, “And on top of that, people were installing plugins like ours, Rapportive, but also Boomerang, Mixmax, Clearbit, you name it, they had it. And each plugin took those problems of clutter, memory, CPU, performance offline, and made all of them dramatically worse.”

Vohra had one question in his mind — how different would the email experience be if it was designed today instead of 12 years ago?

‍ Superhuman was born to give professionals the email experience that they have been long waiting for. Smooth, easy on the eyes, and most importantly, blazingly fast.

But, there was one elephant in the room.

The idea of building a better email service than the existing players sounded great. However, going against some of the biggest brands of Silicon Valley required more than a bad personal experience with Gmail. 

The Superhuman team needed evidence that such a product is actually desirable.

Superhuman’s Challenge: Establishing product-market fit

The team at Superhuman was competing against the email services of Apple, Google, and Microsoft which made the product-market fit quite crucial.

But how do you know whether you have achieved product-market fit?

How did Superhuman do it

Vohra and his team came up with an innovative idea to measure product-market fit by testing crucial hypotheses and focusing on the right target audience.

Superhuman had two hypotheses :

• People are dissatisfied with Gmail and how slow it is.
• People are also dissatisfied with third-party email clients and how buggy they were.

In a product management case study , Vohra explained how to find the right audience — the users who would be ‘very disappointed’ if they could no longer use your product. After identifying them, all you have to do is build the product as they want it.

3. Medium: “Highlights” feature

Evan Williams co-founded Blogger and Twitter which has helped millions of people share their thoughts with the world. Although both platforms became quite popular, they still couldn’t deliver the best reading experience to their users. Blogger allowed readers to browse topics by authors only and Twitter made it difficult for authors to aptly describe themselves.

He quickly recognized the need for a publishing platform that delivers a diverse experience for the readers and allows the authors to speak their hearts.

That’s how Medium was born. It enabled readers to browse articles by topics and authors, helping them to gain different perspectives on any particular subject. It also allowed everyone from professional programmers to amateur chefs to share their insights with the world as they wanted it.

The developers slowly added more features to Medium such as tags, linked images, social cards, and sharing drafts as it evolved through the years.

One of the many notable features of the platform is the “Highlight” feature — where you can select any particular post section and treat it as a mini-post. You can comment on the Highlight or tweet it, which is handy for both personal revision and sharing interesting snippets with others.

Medium’s Challenge: Determining whether “Highlights” added value

Medium faced a challenge while determining a metric that can give them an accurate assessment of the desirability of this feature. In other words, they needed a metric that would tell them whether the “Highlights” feature made user interactions better and more rewarding.

How did Medium do it

The team at Medium solved the challenge by shifting their focus to one crucial metric rather than multiple vanity metrics such as organic visits and retention time which signifies how much value your users are getting out of your product based on retention rate. 

For Medium, it was Total Time Reading (TTR) . It is calculated by estimating the average read time which is the number of words divided by the average reading speed (about 265 WPM) and adding the time spent by the reader lingering over good paragraphs by tracking scrolling speed.

4. Ipsy: Managing distribution 

Michelle Phan started her journey as a YouTuber who recognized the importance of makeup in someone’s self-expression. She has been sharing beauty tips and makeup tutorials with her audience since 2007. 

While on a trip to Thailand, she observed how little girls scrambled to pay for makeup samples in front of vending machines. Five years later, she launched a subscription-based Glam Bag program — where the customers will receive 4-5 deluxe-sized samples of makeup products.

MyGlam, as it was known back then, quickly gained over half-a-million monthly subscribers which created one of the biggest online beauty communities.

Phan quickly realized what she wanted to do — to build a brand for women who wanted to share their perspectives on beauty and meet like-minded people with similar interests and styles.

Ipsy , which comes from the Latin root “ipse” meaning “self”, was created by Phan, Marcelo Camberos, Jennifer Goldfarb, and Richard Frias to expand the user experience.

Although Phan knew how to convert viewers into paying customers, executing a marketing strategy by scaling it up was challenging.

Ipsy’s Challenge: Managing a content distribution strategy

The first makeup tutorial by Michelle Phan has now over 12 million views. Videos like that helped Phan get her first subscribers on her MyGlam program.

This shows the importance and impact of influencer-led content on revenue for businesses in the beauty industry.

However, running an influencer content distribution strategy involves collaborating with multiple passionate influencers. It was challenging to find like-minded influencers who will promote only one brand. Moreover, when working with influencers, it's important to implement effective content moderation to make sure the posted content aligns with your goals.

Phan and her team had a simple solution for this.

How did Ipsy do it

Phan and Spencer McClung, EVP of Media and Partnerships at Ipsy, partnered with beauty influencers like Bethany Mota, Promise Phan, Jessica Harlow, and Andrea Brooks who were already subscribed to MyGlam to create content exclusively for Ipsy.

In a case study analysis, McClung revealed that it put Ipsy on a content-based growth loop where the content was created by both the influencers and customers for the beauty community.

Sponsored content for products by influencers helped them increase their reach and helped Ipsy get more loyal customers. This growth loop gained Ipsy over 3 million monthly subscribers .

5. Stitch Fix: Mastering personalization

Katrina Lake, the founder of Stitch Fix , realized back in 2011 that apparel shopping needed an upgrade. eCommerce failed to meet the expectations of the shoppers and retail shops were falling short in terms of options.

In an interview with The Cut , she revealed "Searching online for jeans is a ridiculously bad experience. And I realized that if I imagined a different future, I could create it."

After realizing that no one has merged data and fashion shopping, she set out to make a difference. She started a personal styling service out of her apartment in 2011 when she was pursuing her MBA from Harvard.

Lake relied on SurveyMonkey to keep track of her customer’s preferences and charged $20 as a styling fee. In late 2012 Eric Colson, then the VP of data science and engineering at Netflix, joined Lake on her journey of crafting the future of retail.

Lake and Colson wanted to give their customers much more than just personalized recommendations.

Stitch Fix’s Challenge: Building a personalized store

Stitch Fix wanted to give their customers more than just personalized recommendations — they wanted to build a personalized store for them where everything they look at, from clothes to accessories, matches their flavor.

But everyone’s body dimensions, preferences, budgets, and past choices are unique which can make building a personalized store difficult.

The team at Stitch Fix found a simple yet effective solution for this challenge.

How did Stitch Fix do it

Katrina Lake, CEO of Stitch Fix, revealed in a case study that personalization is crucial for the onboarding, retention, and monetization of customers.

When signing up, Stitch Fix asks you a few questions about your fashion choices and picks clothes that look the best on you. Furthermore, the collections in your personal store will keep improving as it continuously learns more about your personal preferences.

Also, there is no subscription fee which makes Stitch Fix a great option for occasional shoppers. Suggested Read: Canva’s Success Tale in the World of Design

6. Pinterest: User retention

Ben Silbermann started his tech career at Google’s customer support department. Although he loved the company and believed in its vision, he quickly became frustrated as he wasn’t allowed to build products.

With support from his girlfriend (now wife) Divya and a college friend Paul Sciarra (co-founder), Ben created an app called “Tote” in 2009 which was described as a “catalog for the phone”. Tote allowed users to catalog their favorite items and will be alerted whenever they were on sale so they can make a purchase.

However, the users used it to share their collections with each other instead. Ben recalled how he collected insects as a kid and loved sharing his collection with others. He recognized how people, in general, love to do that.

And, just like that, Pinterest was born where users can “pin” whatever they are interested in and add it to their personal collections.

Pinterest quickly became a hit and entered the global market.

Despite huge success within the US, Pinterest struggled to retain users globally. The team realized that the primary reason users churned is that something stopped them from getting the product’s core value — building personal collections.

Pinterest’s Challenge: Helping customers quickly realize the core value

There are many things that can prevent a user from accessing a product’s core value and one of them is internal friction within the product.

Pinterest’s product folks zeroed in on the one feature that was the gateway to the product’s core value — the “Pin It” feature.

Users outside the US simply couldn’t relate to the term, even though all it did was save the item they like to their personal collection.

How did Pinterest do it

The “Pin It” feature of Pinterest is linked directly to its brand identity. Casey Winters, former growth product lead at Pinterest, suggested changing it to “Save”, particularly in areas outside of the US.

As of the third quarter of 2022, it has over 445 million monthly users all over the world exploring various “ideas” to build collections for sharing with their friends.

Casey concludes in the product management case study that checking whether the users are getting your product’s core value is pivotal in solving most of your growth challenges.

Key Takeaways

Case studies for product management contain in-depth insights that help product teams improve their approach toward their product’s ideation, analysis , development, and commercialization.

The six product management case study examples we reviewed above give these crucial insights:

• Slack : Don’t forget to use social media for marketing your product before its launch.
• Superhuman : Focus on the users that will be “very disappointed” if they can’t use your product anymore to achieve product-market fit.
• Medium : Track the one metric that tells you whether your users are getting value from your product rather than vanity metrics such as organic traffic.
• Ipsy : Partner with influencers to educate your target audience on how to get the most out of your product.
• Stitch Fix : Learn about what your users want and recommend them just that.
• Pinterest : Continuously experiment by changing multiple variables to uncover new growth opportunities.

To put these lessons into practice, you need to provide your team with the right tools that help them interact with your users, learn about their preferences, monitor their usage data, plan the next steps, and manage product development effectively.

A product manager case study interview begins with the interviewer giving you a broad, ambiguous business or product question. Examples of questions you may see include:

• How would you design a product that does a particular function or serve a particular purpose?
• How would you improve a particular product?
• How would you improve sales for a particular product?
• How should we respond to the actions of a competitor?
• Is there a company we should consider acquiring?
• Should we enter a new market?

Typically, companies will ask these questions for a particular product that the company sells. However, companies may use other, more well-known products instead if their products are too technical, complicated, or obscure.

What are the Different Types of Product Manager Case Study Interviews?

There are four major types of product manager case study interview questions: product design, product improvement, product growth, and product strategy questions.

Product Design Case Study Interview

Product design case study interviews ask how you would design a particular product or service. Examples of product design case study questions include:

How would you design an alarm clock for the blind?

• How would you design a smart refrigerator that helps users reduce food waste?
• How would you design a mobile application for children to learn a new language?
• How would you design a user-friendly interface for a voice-controlled virtual assistant device?
• How would you design an interactive museum exhibit to engage visitors in learning about ancient civilizations?

Product Improvement Case Study Interview

Product improvement case study interviews ask how you would improve an existing product or service. Examples of product improvement case study questions include:

• How would you improve the iPhone?
• How would you improve Google Maps?
• How would you improve Spotify?
• How would you improve the microwave?
• How would you improve the check-in process at a hotel?

Product Growth Case Study Interview

Product growth case study interviews ask how you would grow sales for an existing product or service. Examples of product growth case study questions include:

• How would you increase the number of Netflix subscribers?
• How would you increase the number of daily active users on Instagram?
• How would you increase customer engagement on Tik Tok?
• How would you increase revenue for LinkedIn?
• How would you increase profit for Amazon?

Product Strategy Case Study Interview

Product strategy case study interviews ask how you would make strategic business decisions regarding a product, service, or for the company overall. Examples of important strategic decisions include:

• Deciding how to respond to a competitor
• Deciding how to price a product
• Deciding whether to acquire another company
• Deciding whether to enter a new market
• Deciding whether to launch a new product

Why Do Companies Use Product Manager Case Study Interviews?

Companies use product manager case study interviews to simulate problems that product managers face daily, evaluate how candidates think, and predict on-the-job success.

1. Simulate challenges that product managers face daily

Product manager case studies closely simulate the problems that product managers face in their role. By presenting candidates with real world scenarios, companies gain valuable insight into how candidates react when faced with a challenging, ambiguous, or broad problem.

These simulations provide a glimpse into how the candidate may actually perform as a product manager. Through product manager case study interviews, companies assess candidates' readiness to tackle the diverse array of challenges inherent in product management roles, ensuring they possess the necessary skills and mindset to excel.

2. Evaluate how candidates think

Conducting product manager case study interviews allows companies to evaluate not only what candidates know, but also how they think. By presenting candidates with hypothetical scenarios or problems to solve, companies gain insight into their thought processes, analytical abilities, and approach to decision making.

This assessment goes beyond assessing technical knowledge or specific skill sets, focusing instead on candidates' problem solving capabilities, creativity, and critical thinking skills.

3. Predict on the job success

Product manager case study interviews play a pivotal role in predicting candidates' on-the-job success by providing a glimpse into their ability to apply their knowledge and skills in practical contexts.

By evaluating candidates' performance in simulated scenarios relevant to the role, companies can gauge their potential to drive product success, collaborate with cross-functional teams, and deliver tangible outcomes.

Candidates that do well in product manager case study interviews signal a readiness to tackle the challenges of product management, minimizing hiring risks and increasing confidence in their ability to contribute meaningfully to the company’s objectives.

What Do Product Manager Case Study Interviews Assess?

Product manager case study interviews assess: problem solving skills, communication skills, product vision and strategy, creativity and innovation, and industry knowledge and expertise.

Problem solving skills

Product manager case study interviews quickly assess a candidate's problem solving skills. These case studies simulate real world challenges, allowing hiring managers to observe how candidates approach complex problems, break them down into manageable components, and develop viable solutions.

By evaluating a candidate's ability to think critically, creatively, and analytically, companies gain insight into their capacity to navigate the different challenges faced as a product manager.

Communication skills

Effective communication is a crucial skill for product managers who must interact with diverse stakeholders across an organization. Product manager case study interviews provide an opportunity to evaluate a candidate's ability to articulate their thoughts clearly, convey complex ideas succinctly, and engage stakeholders effectively.

Strong communicators can convey product vision compellingly, aligning stakeholders around a shared objective. They can build rapport and trust, facilitating seamless teamwork and driving successful product outcomes.

Product vision and strategy

Central to the role of a product manager is the ability to formulate a compelling product vision and strategy. Product manager case study interviews allow companies to assess a candidate's capacity to think strategically, envision the future trajectory of a product, and develop a product roadmap.

Through articulating a clear product vision, defining measurable objectives, and outlining a coherent strategy, candidates demonstrate their strategic acumen and ability to translate abstract concepts into actionable plans.

A strong understanding of market dynamics, customer needs, and competitive landscape informs a robust product strategy, enabling candidates to devise innovative solutions that resonate with target audiences and drive growth.

Creativity and innovation

In an increasingly competitive landscape, companies seek product managers who can infuse creativity and innovation into their product development process. Product manager case study interviews provide a way to evaluate a candidate's ability to think outside the box, challenge conventional wisdom, and generate novel ideas.

Candidates are tasked with solving hypothetical problems or brainstorming innovative features, offering insights into their creative problem solving skills and ability to push boundaries.

By encouraging candidates to explore unconventional solutions, companies identify individuals who can drive product differentiation and deliver transformative products that captivate users and outpace competitors.

Industry knowledge and expertise

A deep understanding of the industry landscape is essential to being a great product manager. Product manager case study interviews allow companies to assess a candidate's industry knowledge, domain expertise, and familiarity with relevant market trends and technologies.

Candidates are expected to demonstrate their understanding of industry dynamics, customer behaviors, regulatory considerations, and emerging technologies that may impact product development.

How to Solve Product Manager Case Study Interviews

For each type of product manager case study interview question, we’ve detailed the exact steps you should follow to deliver an outstanding answer and impress your interviewer.

How to Solve Product Design or Improvement Case Study Interviews

When asked how you would improve or design a product, resist the urge to list the first few ideas that come to your head. Instead, follow this systematic approach to demonstrate to the interviewer how you think about the product improvement and design process.

There are six main steps to solving product design or improvement case study interviews.

1. Define the goal

It is difficult to design or improve a product unless you have a specific and clear goal in mind. What are you trying to achieve?

The way you design or improve a product will change drastically depending on what you are trying to achieve. So, it is important that you confirm with the interviewer what the explicit goal is.

Are you trying to increase the number of monthly users? Are you trying to increase revenue per user? Is the goal to increase customer engagement? All of these different goals have drastically different solutions.

2. Identify a customer segment to target

The goal of this step is to focus and narrow down the scope of product improvement or design to one specific customer segment.

There are two reasons why you should do this.

One, customers can have a wide range of needs and preferences. Trying to improve or design a product that would benefit every single customer can be very challenging.

Two, by focusing on a specific customer segment, you can develop product improvements and designs that are more specific and tailored to the segment’s needs. You will avoid suggesting product ideas that are generic and not impactful.

Therefore, start by listing the different customer segments that come to mind. Select one segment and provide a reason why you are focusing on that segment.

You might choose a segment because they are the largest segment or you might pick a segment if their needs are underserved.

3. Select a pain point to focus on

Brainstorm a list of pain points for the selected customer segment. These can be unmet customer needs or features of the product that customers find frustrating, time-consuming, or difficult to use.

Select one pain point and provide a reason why you are focusing on it. You might select a pain point if it is the most common, the most severe, or the most practical to solve for.

4. Brainstorm product improvements or designs

Now that you have chosen a pain point to focus on, brainstorm a list of different ways to solve for that pain point.

Try to have at least 3 – 5 different ideas. Include a few ideas that are creative and unconventional. This demonstrates originality and out-of-the-box thinking.

If you are having difficulty generating enough ideas, you can use the SCAMPER framework to help you brainstorm ideas.

SCAMPER stands for substitute, combine, adapt, modify, put to another use, eliminate, and reverse.

• Substitute : Replace an element or feature with something else
• Combine : Merge different elements or features to create something new
• Adapt : Alter an existing idea to better fit a new context or need
• Modify : Make changes to the attributes, such as size, shape, color, or other characteristics
• Put to another use : Find new applications for an existing idea
• Eliminate : Remove unnecessary components or features
• Reverse : Change the order or perspective of elements or features

5. Assess which idea is best

For this step, create a list of criteria to assess your different ideas. Common criteria include:

• Magnitude of impact
• User experience
• Ease of implementation

Select the most important criteria based on the nature of the product and the pain point. Afterward, assess each of your product ideas based on the list of criteria you have developed.

You can assess your ideas either quantitatively or qualitatively.

The most common way to quantitatively score ideas is to give them one, two, or three points for each criteria. The idea that has the highest total number of points will be chosen.

Some criteria may be significantly more important than others. In this case, you can consider weighting the point values differently. For example, if the magnitude of impact is by far the most essential criteria, you can double the point value. Each idea will be given two, four, or six points for this criteria.

In assessing your ideas qualitatively, talk through how each idea performs on the criteria you have selected. Choose the improvement or design that has the most positive assessment overall.

6. Explain how you would test this

After you have selected your best idea, suggest how you would test whether this product improvement or design works. Specify what metrics you would want to measure to determine this.

This step is not always necessary, but it demonstrates to the interviewer that you can think like a product manager. Product roles involve a lot of testing and iterating on features and improvements.

A/B testing is the most common way to test a new product feature or design. In A/B testing, you compare the performance of two variations of a product against one another.

Typically, you would run an experiment in which one group of customers is given the original or older product and another group of customers is given the new and improved product.

After defining the right metrics to measure performance, you can determine which version of the product performs better.

How to Solve Product Growth Case Study Interviews

They key to solving product growth case study interviews is to have a comprehensive growth framework where you can systematically list and talk through all of the major ways to grow.

A case study framework is a tool to structure and break down business problems into smaller components.

You can think about growth through two major categories, organic growth and inorganic growth. These two categories form the foundation of our growth strategy case framework.

Organic growth

The most common type of growth that companies pursue is organic growth, which is growth driven by expanding output or engaging in internal activities. In other words, the company is growing through its own capabilities and efforts.

Organic growth can be segmented into growth through existing revenue sources and growth through new revenue sources.

Growth through existing revenue sources is either driven by an increase in quantity of units sold or by an increase in average price per unit sold.

To increase the quantity of units sold, a company can:

• Improve their product
• Decrease prices
• Sell through new distribution channels
• Target new customer segments
• Expand into new geographies
• Invest more in marketing and sales
• To increase the average price per unit sold, the company can:
• Increase prices for their products
• Focus on selling higher priced products

Remember that changing prices will impact quantity of units sold, so it is important to look at the net effect price changes have on revenue.

To drive growth through new revenue sources, a company can:

• Launch new products
• Launch new services

 Inorganic growth

Inorganic growth, on the other hand, is growth driven by acquisitions, joint ventures, or partnerships.

The first way that a company can grow inorganically is by acquiring another company. This gives the acquiring company all of the revenue that the acquisition target generates. In addition, there may be revenue synergies that the acquiring company can realize.

Acquiring a company gives the acquiring company access to the acquisition target’s distribution channels, customers, and products. The acquiring company may be able to increase revenues by cross-selling products, up-selling products, or bundling products together.

In a joint venture, two or more companies enter a business arrangement in which they pool together resources and share risk in accomplishing a particular task. Each company in the joint venture is responsible for profits, losses, and costs associated with the project.

A partnership is an association between two or more companies that provides some kind of benefit to each partner. This is slightly different from a joint venture because in a partnership, companies do not necessarily have to combine resources or efforts. They just need to be associated with each other.

How to Solve Product Strategy Case Study Interviews

When answering a product strategy question, you should create a framework to structure your thoughts rather than saying the first few ideas that come to mind.

As a reminder, a framework is a tool to structure and break down business problems into smaller components. The answers to the questions in your framework will help you answer the overall product strategy question.

There are six steps to creating outstanding frameworks to answer product strategy case study interview questions.

1. Memorize eight robust business categories

There are eight broad business categories that are frequently looked at when making product strategy decisions.

By memorizing these eight categories, you’ll have an easier time creating an outstanding framework rather than having to create frameworks from scratch each time.

These eight business categories are:

• Market: market size, market growth rate, average profit margins in the market, market trends or changes (e.g., technology, regulation)
• Competition: number of competitors, market share of competitors, competitive advantage of competitors, trends or changes happening among competitors
• Company: products and services, strengths, competitive advantages, capability gaps, weaknesses, growth trajectory, synergies
• Product: product benefits, product drawbacks, product differentiation, product lifecycle stage
• Customer: number of customer segments, characteristics of each segment, attractiveness of each segment, customer needs and preferences, customer purchasing behaviors
• Profitability: revenue, costs, breakeven, return on investment, payback period
• Alternatives: alternative markets, alternative products, alternative partnerships or strategic alliances, alternative acquisition targets, alternative investments, alternative strategies
• Risks: major risks, likelihood of risks, severity of risks, mitigation of risks

For each of these broad business categories, we’ve included a few potential topics to give you a sense of what each category means or encompasses.

You will only need to memorize the eight broad business categories. You do not need to memorize all of the potential topics under each.

2. When asked a strategy question, ask for a few minutes to structure your thoughts

When given a product strategy case study interview question, ask for a few minutes to structure your thoughts. Almost every time, the interviewer will give you time to develop a framework.

3. Mentally run through the eight business categories and select the 3-4 most relevant ones

Next, mentally run through the eight business categories that you’ve memorized and select the 3-4 most relevant ones.

3-4 is the ideal number of categories for your framework. It is the right balance of comprehensiveness and simplicity.

Any fewer than 3-4 categories and your framework may not be comprehensive enough. You may be missing critical questions that are necessary to answer the strategy question.

Any more than 3-4 categories and your framework becomes too large and complicated. You also risk having redundancies in your framework.

4. If you are unable to select 3-4 relevant business categories, think of your own business categories to include

If you are unable to get 3-4 categories in your framework after running through the memorized list of business categories, then it is time to think of your own business categories to include.

This happens more commonly when given atypical or unusual product strategy case study interview questions.

Remember, the eight broad business categories you memorized work for the vast majority of strategy questions, but does not cover all of them.

5. Add specific questions under each business category you’ve selected

Once you have identified the 3-4 major categories in your framework, add sub-bullets or questions underneath each of them to add more detail.

6. Walk the interviewer through your framework and answer

When you’ve finished developing your framework, walk your interviewer through it.

At the end of each major category, give your opinion on which answer or recommendation it supports.

Once you’ve walked the interviewer through your entire framework, you should have an overall answer to the product strategy case study interview.

Product Manager Case Study Interview Examples

We’ve compiled a few product manager case study interview examples with complete answers below. These examples should give you a good sense of what outstanding answers sound like.

Product Manager Case Study Interview Example #1

How would you improve YouTube?

For this question, I’ll assume that the goal of the improvement is to increase user engagement on the platform, which can be measured as the amount of time a user spends on YouTube.

First, I’ll think through the different customer segments and pick one to focus on. Three customer segments immediately come to mind:

• Entertainment seekers are users that are bored who are looking for interesting videos to watch to pass the time
• Information seekers are users looking to learn a new skill or acquire information on a topic
• Music seekers are users looking for background music or sounds to play while they are doing something else

Out of these segments, I will focus on entertainment seekers because this segment probably makes up the most significant portion of YouTube’s user base.

Next, I’ll identify a pain point to focus on. Entertainment seekers have a few different pain points:

• The discovery process they go through to find entertaining videos takes time and effort
• Entertainment seekers find long videos dull and too slow to watch
• They get irritated when videos have clickbait titles that do not live up to expectations.

Among these pain points, I’m going to focus on the tedious video discovery process because it is probably the biggest pain point for these users.

Now, I will brainstorm a few ideas on how to make the video discovery process easier.

• YouTube could recommend videos based on videos that friends have seen. Since friends tend to have similar interests and tastes, these videos will likely be entertaining to entertainment seekers
• YouTube can have a continuous, curated video feed such that users do not have to search for the next video. Users can click on a skip button to immediately jump into the following video, which will be curated by an algorithm based on video history
• YouTube could send a curated playlist to the user each day. These videos would be selected by an algorithm based on video history

I will assess each of these ideas on their impact, user experience, and ease of implementation.

The first idea, recommending videos based on videos that friends have seen, would have minimal impact if the user does not have friends that use YouTube frequently.

Additionally, this idea does not change the user experience much because entertainment seekers would still need to decide whether to watch a recommended video. The upside of this idea is that it would not be difficult to implement.

The second idea, having a continuous, curated video feed, could have a tremendous impact. It removes the burden of decision-making from entertainment seekers because YouTube videos are automatically played.

The user experience is also an improvement because the user only needs to click a skip button when they are bored. The downside of this idea is that developing a good algorithm could require substantial investment.

The third idea, sending a curated playlist to the user each day, would have some impact on users. The decision making process is slightly simplified because the user receives a shorter list of videos to choose from. However, once the playlist is finished, the user would still need to look for more videos on their own. 

Additionally, the user experience is not ideal. Getting an email or notification every day can be annoying. The upside of this idea is that it is the most straightforward to implement.

 Based on my assessment, the continuous, curated video feed seems to be the most promising. 

To test this idea, I would develop a minimal viable product and use A/B testing to assess the performance of this feature.

One customer group would be given access to this feature while another customer group would not. I would measure the difference in minutes of video consumption between the two groups for one month to determine if user engagement has increased.

Product Manager Case Study Interview Example #2

For this task, let’s assume that the goal is to design an alarm clock that works reliably in waking up the user and is as easy to use as possible. 

Additional alarm clock functionalities, such as checking the weather or listening to the radio, will not be considered.

The customer segment has already been defined, the blind.

There are four use cases that we need to design for:

• Setting an alarm
• Checking to see if the alarm has been set
• Waking up the user
• Checking the time

For each of these use cases, we can brainstorm a few potential ideas and evaluate the pros and cons for each to decide which design is optimal for our goals.

To set an alarm:

• Design a voice assistant (e.g., similar to Siri or Alexa): This is quicker than a touchpad and can easily set an exact alarm time to the second. Additionally, the voice assistant can repeat the time set out loud so that the user knows the correct time has been set. However, there could be dictation issues for people with accents and this can only be done when the environment is relatively quiet.
• Design a braille touchpad: This would complicate the alarm clock by adding additional buttons. It would also take a longer time to set an alarm. The user would also need to take an additional step to check that the alarm has been set correctly once entered.

To check if the alarm has been set:

• Design a voice assistant that can answer the question of whether the alarm has been set: The user would not need to walk to the alarm clock to check if the alarm has been set. However, this needs to be done in a relatively quiet environment.
• Design a button that when pressed will play the time, the alarm set time, and whether the alarm is on/off: This provides all the information the user needs, but time-consuming as the user will need to hear all of the information each time. The user also needs to walk to the alarm clock to use this.
• Design a button that when pressed, vibrates if the alarm has been set: This communicates the information more quickly, but the user still needs to walk to the alarm clock to use this.

To wake up the user:

• Use visuals: If the user is blind, they likely won’t be able to see anything, especially if they are asleep.
• Use sound: This is what almost all alarm clocks use.
• Use touch: The alarm clock can vibrate to wake the user. However, it is unclear if this would reliably wake up the user.
• Use smell or taste: This is a very unconventional approach to designing an alarm clock. Users probably don’t want to be forced to smell or taste something. It is unclear whether the taste or smell would be strong enough to reliably wake up the user.

To check the time:

• Design mechanical braille buttons that change by the minute: This seems complicated to design and would likely increase the cost of the alarm clock. 
• Design a button that says the time out loud when pressed: This is less complex than designing mechanical braille buttons that change by the minute. However, the user still needs to walk to the alarm clock to check the time.
• Design a voice assistant to say the time out loud when asked: The user would not need to walk to the alarm clock to check the time. However, this can only be done in a relatively quiet environment.

Based on this, it seems that a voice assistant alarm clock that wakes up users with sound would be most suitable for our user.

Product Manager Case Study Interview Frameworks

There are several product manager case study frameworks that candidates may find helpful to be familiar with. These include the: 4P’s framework, design thinking framework, growth framework, product development lifecycle framework, and SWOT analysis framework.

4P’s Framework

The 4P’s framework is a fundamental marketing framework used to analyze and develop marketing strategies for products or services. It consists of four elements, each representing a different aspect of marketing strategy:

• Product : Analyze the product itself, including its features, functionality, design, and user experience. Consider how well the product meets user needs and differentiates itself from competitors
• Price : Assess the pricing strategy, including pricing models, pricing tiers, discounts, and promotions. Consider factors such as value proposition, cost structure, and willingness to pay
• Place : Evaluate the distribution channels and placement strategy for the product, including online platforms, retail stores, and partnerships. Consider how to reach target customers effectively and efficiently
• Promotion : Examine the marketing and promotional tactics used to raise awareness and drive sales of the product. Consider advertising, public relations, social media, and other promotional channels

Design Thinking Framework

The design thinking framework is a human-centered approach to problem solving and innovation that is used to address a wide range of challenges and opportunities involved with product or service design.

It involves a structured process that encourages empathy, creativity, and collaboration to develop solutions that are user-centered, feasible, and viable. Here's how the design thinking framework is typically used:

• Empathize : Empathize with users to understand their needs, motivations, and pain points. Conduct user interviews, surveys, or observations to gain insights
• Define : Define the problem space, synthesizing research findings into clear problem statements or user personas. Articulate the specific challenges or opportunities
• Ideate : Brainstorm and generate creative solutions to the defined problem, encouraging divergent thinking and exploring a wide range of possibilities
• Prototype : Develop low-fidelity prototypes or mockups to visualize and communicate ideas, soliciting feedback from stakeholders and users
• Test : Gather feedback on prototypes through user testing or validation experiments, iterating based on user insights and refining solutions

Growth Framework

The growth framework, also known as the AARRR framework, is a framework used to analyze and optimize the various stages of the customer lifecycle. It is commonly applied in growth marketing and product management to drive user acquisition, activation, retention, revenue, and referral.

Here's a breakdown of the growth framework:

• Acquisition : Identify strategies for attracting new users or customers to the product, such as advertising, content marketing, SEO, or partnerships
• Activation : Focus on strategies to convert new users into active and engaged users, such as onboarding processes, personalized messaging, or product tours
• Retention : Explore tactics to keep users coming back to the product and increase their lifetime value, such as email marketing, loyalty programs, or product improvements
• Revenue : Analyze opportunities to monetize the product, including pricing strategies, upselling, cross-selling, or subscription models
• Referral : Consider ways to encourage existing users to refer new users to the product through word-of-mouth, referral programs, or social sharing

Product Development Lifecycle Framework

The product development lifecycle framework is used to guide the stages through which a product evolves from conceptualization to retirement. It outlines the key phases and activities involved in bringing a product to market and managing it throughout its lifespan.

Here's an overview of the product development lifecycle framework:

• Ideation : Generate and evaluate ideas for new products or features, considering user needs, market trends, and business goals
• Research : Conduct market research, user research, and competitive analysis to validate ideas and gather insights for product development
• Design : Define product requirements, create wireframes or prototypes, and design the user experience and interface
• Development : Oversee the development process, working with engineers and designers to build and test the product
• Launch : Plan and execute the product launch, including marketing campaigns, communication strategies, and rollout plans
• Post-launch Iteration : Monitor product performance, gather feedback from users, and iterate on the product based on insights and data

SWOT Analysis Framework

The SWOT analysis framework is a strategic planning tool used to identify and analyze the internal strengths and weaknesses as well as external opportunities and threats facing a business, product, or project.

SWOT stands for Strengths, Weaknesses, Opportunities, and Threats. Here's how each component of the SWOT analysis framework is used:

• Strengths : Identify internal factors that contribute to the success of the product or business, such as unique features, strong brand reputation, or talented team members
• Weaknesses : Identify internal factors that hinder the success of the product or business, such as limited resources, technical constraints, or competitive disadvantages
• Opportunities : Identify external factors or market trends that present opportunities for growth or innovation, such as emerging technologies, new market segments, or changing consumer behaviors
• Threats : Identify external factors or challenges that pose risks to the product or business, such as competitive threats, market saturation, regulatory changes, or economic downturns

• The types of questions you could get asked
• What a great product manager case study interview performance looks like

2. Learn the right strategies

Now that you have all the background information needed to succeed in product manager case study interviews, the next step is to learn the right strategies to build good interview habits.

It is much more efficient to learn the right product manager case study interview strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to read through our comprehensive product manager interview book . This book provides strategies on exactly what to do and say for over 10+ types of product manager interview questions, such as product design, marketing, estimation, strategy, execution, behavioral, and technical questions.

Before moving onto the next step, you should at least have strategies for the following types of product manager case study questions:

• Product design case study interview questions
• Product improvement case study interview questions
• Product growth case study interview questions
• Product strategy case study interview questions

3. Practice a few product manager case study interviews by yourself

Once you have learned the right strategies, the next step is to practice doing a few product manager case study interviews by yourself.

When practicing product manager case study interviews, it is typically better to practice with a partner than to practice by yourself. Practicing with a partner better simulates the actual product manager interview experience.

However, when you are just starting out, it is better to do the first few cases by yourself because it’ll help you become familiar with the structure and format of product manager case study interviews much more quickly.

 You also won’t have to waste time finding a partner and waiting for a time when they will be available to give you a mock interview.

4. Practice product manager case study interviews with a partner

The next step in preparing for product manager case study interviews is to practice doing cases with a partner. There are many aspects of case study interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing product manager case study interviews with a partner, make sure that you are spending enough time after the mock interview to deliver feedback. Most of your learning and improvement will come from these valuable feedback sessions.

Do not move onto the next step until you have done at least 5 to 10 cases and are beginning to feel more comfortable with product manager case study interviews.

5. Practice with a former or current product manager

At this point, I strongly recommend asking former or current product managers to give you a mock interview. This will significantly help improve your performance on product manager case study interviews.

Doing a practice interview with a former or current product manager is highly beneficial because they know exactly what great answers sound like and can give you high-quality feedback to help improve the quality of your answers.

You can find former or current product managers among your friends, classmates, colleagues, and your broader LinkedIn network.

6. Work on your improvement areas

The last step in preparing for product manager case study interviews is to work on strengthening your improvement areas. Examples of common improvement areas or deficiencies include:

• Developing a comprehensive and structured framework or approach
• Generating creative and innovative ideas
• Using appropriate logic to make decisions
• Considering trade-offs and alternatives
• Communicating clearly and concisely

Try to work on improving one thing at a time. This will be much more effective than trying to improve on all of your weaknesses at once.

How To Conduct a Product Analysis? A Step-by-Step Guide With Case Studies

⭐️ Establish clear objectives for your product analysis to ensure that the metrics you track are meaningful and aligned with your business goals.

⭐️ Dive deep into quantitative and qualitative data to understand user behavior and product performance comprehensively.

⭐️ Online surveys are a powerful tool for gathering user feedback and providing insights for competitive analysis, helping you understand your market position.

⭐️ Regularly map and evaluate the user journey to identify and rectify pain points, bottlenecks, and areas for UX improvement.

⭐️ Use the actionable insights from product analysis to drive continuous improvement and innovation, ensuring your product remains user-centric and competitive.

Do product analytics metrics haunt you? Are there so many to choose from that you don't even know where to start? Well, product analysis can be an overwhelming task if you don't approach it strategically.

With this guide, for example.

We'll show you that you don't have to measure everything to conduct a sound product analysis. We'll take you by your hand to slowly but surely go through every step of the process. And finally, we'll show you how others do it using online surveys as an additional data source of customer feedback .

Buckle up, and let's go 🚀

So, what is digital product analysis?

Product analysis is a process of analyzing how customers engage with digital products. It involves tracking user behavior, understanding engagement patterns, and using this information to improve the product's functionality and user experience.

Gathering real-time data helps you move beyond surface-level metrics to uncover actionable insights. With this information, you can optimize customer journeys, increase customer lifetime value , and make data-driven decisions to grow your business.

What is the purpose of product analysis?

Would you like the short or long answer? Before we decide on that, let's see what John Cutler, former Product Evangelist at Amplitude, says about a lot of the Product teams out there:

Many teams have very little sense of their current impact. So the idea of improving decision quality doesn't resonate. It's a paradox of sorts. Without situational awareness, the idea of improving situational awareness feels distant and abstract.

In: The Analytics ROI Paradox

You probably get the idea by now and the short answer as well. But just for the record—you need product analysis to know .

To know if your product sticks, identify trends, assess your current impact, and make it bigger. We could also say it's for data-driven decision-making, but it's 2024, and we're all fed up with buzzword-dropping.

Now for the long answer . You just cannot afford guesswork anymore. A comprehensive product analysis process is necessary to gather relevant data on how different user groups engage with your product.

You need to know precisely what the user journey looks like, how the product features perform, what the customer satisfaction level is, and where your product lands in competitive product analysis.

It's the only way to increase the quality of your decisions and:

💎 Create a user-centric product Your users should always be at the core of what you create, so a thorough understanding of product analytics data is crucial to developing a product they'll fall in love with.

💎 Build well-targeted marketing campaigns There's no money to burn on marketing anymore, so you better get to know your users well. And fast. Perform user segmentation to build user personas and effectively connect with your potential customers.

💎 Drive continuous improvement A digital product is a never-ending story, a non-finite commitment, and so should be improving on it. The product analysis process should be, at its heart, continuous, meaning it should be a part of daily work for Product teams. Only then can it bring value and unlock the potential of your product.

Step 1. Establish goals and objectives

"How smart," you might think ironically. As blunt as this point is, it is also unavoidable if you aim to implement product analytics successfully.

You may track an endless number of "key" metrics, but will they make any sense if you don't define product analysis objectives in the first place? Well, they might, but chances are your team will start eating its own tail trying to figure out what's really important.

So, you must ask yourself a fundamental question: Why do you want to run a product analysis? 🧐

Is it to monitor the overall product health or user satisfaction? Maybe it's about troubleshooting your conversion or checking if your product onboarding goes smoothly.

Product analytics metrics will also show user engagement and help you perform the retention analysis or measure new feature impact, as well as prioritize product roadmap

A thorough product analysis of your user segments can also pinpoint the target market, so you actually position yourself in the right niche, multiplying your chances for conversion .

It's your call, but before you get down to analyzing data, you must have your objectives clear.

Step 2. Know your product and how users interact with it

No matter the "why" behind it, if you're analyzing feature adoption or how users engage post-onboarding, you must know the ropes of your product. Inside out. And back.

But it doesn't end here. Once you master all the intricacies of your product, it's time to do the very same thing from the user's perspective because it's not about you (quoting the Ancient One ⤵️)

Gather data on product overview

Before you start looking at the product through your users' lens, make sure you have the basic facts straight and you know the answer to this, seemingly simple question:

What problem does your product solve, and how does it work?

Apart from the obvious, it should also reveal your value proposition along with the target audience.

Now, how do you learn your users' perspective?

The best way to start off—e at your own dog food 🦴 . It's the fastest way to understand how your product features work in practice and what can potentially cause user concerns.

Having the basics grounded, let's move to data collection and dig into your qualitative and quantitative data.

Quantitative data to capture user behavior

Let's put it straight: you can't and shouldn't measure everything . Too many metrics in your product data collection will overload your teams and obscure significant data. Nonetheless, there is a golden standard of key metrics to track, no matter what.

📡 User behavioral analytics will help you understand how users interact with your product. Metrics to have a look at page views, clicks, session duration, and conversion rate.

📡 User retention and churn are the ultimate scales of your success, and you need to be on top of them. Always.

A consistently growing retention level is a sign that you deliver as a company—the product performance is good, marketing strategies work, and user expectations are fulfilled (or even surpassed).

Conversely, with a growing churn rate, you need to dive deep into product analysis and find the culprit fast. Is it the product itself? Maybe it's positioned to the wrong target audience? Or maybe it crashes way too often?

📡 Customer lifetime value (LTV) is a metric you can use to segment your users to identify patterns in their behavior. Especially those who bring the most revenue. Analyze their customer journey , how they use the product, what they need , and...act accordingly.

Following your top-tier user preferences gives you a fair chance of boosting conversion and pushing your product in the right direction.

💡TIP: Don't be satisfied with raw data.

No matter what metrics you choose to follow, remember to always build a context around them; otherwise, they'll end up in the vanity metrics cemetery. For example, 100k pageviews standalone look good, but with a 4-second average session duration or a 1% conversion rate, there's clearly an issue to solve.

Qualitative data to capture user insights

Quantitative and qualitative data are the yin-yang of product analysis. You can never grasp the entirety of user experience without analyzing both.

So, where should you take qualitative data from while running a product analysis report?

💌 Customer feedback comes in all shapes and sizes. You can get customer feedback from your customer-facing teams : Support, Success, and Sales. While it's an important source of learning the user's POV, it shouldn't be the only one.

We will make an educated guess that most of your customer base will be reluctant to reach out to support. In fact, the ACA Survey Report shows that 43% of customers would rather clean a toilet than call customer support.

Although we should probably take this particular result with a pinch of salt, you have to remember that most dissatisfied customers leave silently. That's why it's crucial to be proactive when it comes to collecting customer feedback .

And that's where online surveys come in handy for many different purposes. Be it measuring product satisfaction, feature validation, or finding the product-market fit . Easily distributed at different touchpoints, be it in-product, in-app , website pop-up , or email , online surveys are sidekick to getting customer insights fast and in bulk (and they also serve for the quantitative research!).

💌 Customer interviews are the obvious choice for getting valuable user insights, but they require more resorts and time. However, they are definitely the best method to get an in-depth perspective from your users. Just don't forget that they will make the analysis process longer and will most probably require a separate team member specializing in user research to look into this qualitative feedback to identify patterns and trends.

💌 Customer testimonials and online reviews , again, a rather reactive than proactive way to collect user feedback . Nevertheless, it's crucial to keep a finger on a pulse and react quickly when negative reviews come in. Otherwise, it can end up with trust issues from potential customers and influence your user retention rate.

Step 3. Evaluate user experience

With all the collected data on the table, it's time to use it properly and get down to a proper product analysis to understand user engagement and identify trends. But before, don't forget to map out the digital journey—it will help you analyze data.

Map the user journey

When thinking about digital customer journey mapping , think globally. And focus on the user. Don't get entangled in the intricate relationships between Marketing, Customer Success, or Product teams. Instead, look at it as a whole experience.

Examine how your customers move along the path with user flow data and mark any potential friction point or bottleneck. The product analytics data you collected should help you pinpoint any potential flaw in the user flow that can affect satisfaction levels and even raise the user acquisition cost .

Analyze user behavior data

Understanding how different types of users interact with your product is essential. To stay on top of user engagement, you may want to track metrics such as:

• Page views : Are certain pages or features attracting more attention?
• Clicks : What are users clicking on the most?
• Session duration : How long are users staying on your product?
• Conversion rates : At what rate are users taking the desired action?

Collecting this data with your product analytics tool allows you to notice specific trends among your users. Some may use your product daily, leveraging many features, while others might log in less frequently and use only a few. This will help you build your power and casual user segments—a handy resource for analyzing feature usage and product roadmap prioritization.

You can also consider segmenting users into categories:

• Free vs. paid users: Are paid users engaging more and getting more value?
• Active vs. dormant users: How many users are consistently active? Who has stopped using the product, and who has returned after a period of inactivity?
• Regional differences: Are there usage patterns based on geographic regions?

Performing a user journey analysis can reveal users' paths to achieving their goals within your product. This process will help you identify the following:

• Pain points: Where do users struggle or get frustrated?
• Bottlenecks: Where does the user flow slow down or stop?
• UX improvement areas: Which parts of the product need a design overhaul or simplification?

Tips for a thorough analysis:

💎 Prioritize metrics that reflect user engagement and satisfaction. 💎 Use segmentation to understand different user behaviors and needs. 💎 Map user journeys to visualize the user experience and identify improvement opportunities. 💎 Actively seek out and address user pain points to enhance the overall user experience.

Step 5. Perform competitive analysis

Your product does not exist in a vacuum; thus, you need proficient market intel and knowledge of what's up and coming in your niche. Competitive product analysis is an auxiliary yet powerful tool to enrich your product analysis report.

You can use secondary research to gather information about products you compete with. Compare features, pricing , and unique selling points, and finally, conduct trends analysis to understand the impact of feature adoption over time.

Running a competitive product analysis will help you explain the value of understanding your product's position in the market and how it compares to competitors. But that's not all. You should also discuss using competitive insights to differentiate your product and identify areas for innovation.

Step 6: Optimize and monitor

Okay, with all the data on the table, you now need to put it into action. Based on the gathered user feedback, collected data, and trend analysis, it's time to identify areas for improvement and optimization. How do you do it in practice? Look at some of the case studies below and get inspired.

Remember that monitoring product and user behavior is a continuous commitment. That's why you should establish a regular cadence for running your product analytics.

How user feedback can help in product analysis - case studies

Helps in the continuous discovery (medscape).

Using surveys within a Continuous Discovery framework, Medscape 's Product teams have enhanced their product development by directly incorporating user feedback. Contextual surveys have been key in recruiting users for interviews and validating hypotheses, leading to actionable insights.

This approach underscores the value of user feedback in driving product decisions and fostering customer-centric innovation.

Helps validate new features faster

Intergiro 's product team used in-app surveys to validate new features and collect user insights during the product validation process. They periodically set up surveys in different parts of their product to get pinpoint feedback on specific elements.

For example, when developing a bulk payment feature to improve the payment flow for users who processed hundreds of operations manually, Intergiro first released it as a beta version to companies that provided initial feedback. The beta launch allowed them to collect valuable insights fast and make quick fixes before the public launch, reassuring the team that they provided a valuable addition to facilitate client operations.

Helps find the product market fit

Landing used Survicate's product-market fit survey to continuously measure how well their platform meets user needs and expectations. The PMS survey acts as a health check for Landing's value proposition, providing qualitative feedback that gets analyzed and transformed into new roadmap items.

As Liz from Landing notes, the survey feedback reveals gaps between what they assume users want versus their actual needs.

"Without this feedback, we're looking at an ocean through a straw."

By continuously validating their product-market fit through user insights, Landing can build a community-driven platform that truly meets customer demands.

And for more product-market fit inspiration, dive into PowerUs' story .

More use cases that can help you with product analysis

There are many more examples of how online surveys can help you gather data for sound product analysis. If you're on a mission to improve your customer journey, have a look at Hitta's case , how they employed NPS surveys to pinpoint bottlenecks, and how designing feedback loops helps them.

Speaking about NPS and customer centricity, you should definitely have a peek at how Preply fosters a company culture of "customer obsession" with NPS as their North Star metric.

If you're curious about how you could use the product feedback data, check Workwise's case study . And if you'd like to see if surveys could work along A/B testing and user satisfaction topics— wetter.com's story is a read to recommend.

Back up your product analytics data with customer feedback

Analyzing your product is a must; however, with the amount of data at hand, the vital part is to prepare well. Knowing the "why" behind your product analysis will save you a lot of trouble and potential chaos in your product team.

While quantitative data coming from your product can serve as a good outline for the story you seek to reveal, using customer feedback will fill the gaps with context and give you a fuller picture of the digital journey you offer.

And that’s where Survicate thrives. With us, you can run surveys that collect all kinds of statistical data (NPS, CSAT, CES, to name just a few), but surveys can also uncover more nuanced information collected with open-ended questions . 

Importantly, you no longer have to fear the tedious open text analysis, as Survicate offers an AI text response analysis that will automatically group user feedback into topics, saving you a lot of time (and probably nerves). 

Lastly, while we’ve already mentioned AI, you can also create your surveys automatically by simply describing your needs. Never has survey research been more effortless.

To ensure you’re making the most of your case studies, we’ve put together 15 real-life case study examples to inspire you. These examples span a variety of industries and formats. We’ve also included best practices, design tips and templates to inspire you.

Let’s dive in!

Table of Contents

What is a case study, 15 real-life case study examples, sales case study examples, saas case study examples, product case study examples, marketing case study examples, business case study examples, case study faqs.

• A case study is a compelling narrative that showcases how your product or service has positively impacted a real business or individual. 
• Case studies delve into your customer's challenges, how your solution addressed them and the quantifiable results they achieved.
• Your case study should have an attention-grabbing headline, great visuals and a relevant call to action. Other key elements include an introduction, problems and result section.
• Visme provides easy-to-use tools, professionally designed templates and features for creating attractive and engaging case studies.

A case study is a real-life scenario where your company helped a person or business solve their unique challenges. It provides a detailed analysis of the positive outcomes achieved as a result of implementing your solution.

Case studies are an effective way to showcase the value of your product or service to potential customers without overt selling. By sharing how your company transformed a business, you can attract customers seeking similar solutions and results.

Case studies are not only about your company's capabilities; they are primarily about the benefits customers and clients have experienced from using your product.

Every great case study is made up of key elements. They are;

• Attention-grabbing headline: Write a compelling headline that grabs attention and tells your reader what the case study is about. For example, "How a CRM System Helped a B2B Company Increase Revenue by 225%.
• Introduction/Executive Summary: Include a brief overview of your case study, including your customer’s problem, the solution they implemented and the results they achieved.
• Problem/Challenge: Case studies with solutions offer a powerful way to connect with potential customers. In this section, explain how your product or service specifically addressed your customer's challenges.
• Solution: Explain how your product or service specifically addressed your customer's challenges.
• Results/Achievements : Give a detailed account of the positive impact of your product. Quantify the benefits achieved using metrics such as increased sales, improved efficiency, reduced costs or enhanced customer satisfaction.
• Graphics/Visuals: Include professional designs, high-quality photos and videos to make your case study more engaging and visually appealing.
• Quotes/Testimonials: Incorporate written or video quotes from your clients to boost your credibility.

2. WeightWatchers Completely Revamped their Enterprise Sales Process with HubSpot

WeightWatchers, a 60-year-old wellness company, sought a CRM solution that increased the efficiency of their sales process. With their previous system, Weightwatchers had limited automation. They would copy-paste message templates from word documents or recreate one email for a batch of customers.

This required a huge effort from sales reps, account managers and leadership, as they were unable to track leads or pull customized reports for planning and growth.

WeightWatchers transformed their B2B sales strategy by leveraging HubSpot's robust marketing and sales workflows. They utilized HubSpot’s deal pipeline and automation features to streamline lead qualification. And the customized dashboard gave leadership valuable insights.

As a result, WeightWatchers generated seven figures in annual contract value and boosted recurring revenue. Hubspot’s impact resulted in 100% adoption across all sales, marketing, client success and operations teams.

Hubspot structured its case study into separate sections, demonstrating the specific benefits of their products to various aspects of the customer's business. Additionally, they integrated direct customer quotes in each section to boost credibility, resulting in a more compelling case study.

4. How WOW! is Saving Nearly 79% in Time and Cost With Visme

This case study discusses how Visme helped WOW! save time and money by providing user-friendly tools to create interactive and quality training materials for their employees. Find out what your team can do with Visme. Request a Demo

WOW!'s learning and development team creates high-quality training materials for new and existing employees. Previous tools and platforms they used had plain templates, little to no interactivity features, and limited flexibility—that is, until they discovered Visme.

Now, the learning and development team at WOW! use Visme to create engaging infographics, training videos, slide decks and other training materials.

This has directly reduced the company's turnover rate, saving them money spent on recruiting and training new employees. It has also saved them a significant amount of time, which they can now allocate to other important tasks.

Visme's customer testimonials spark an emotional connection with the reader, leaving a profound impact. Upon reading this case study, prospective customers will be blown away by the remarkable efficiency achieved by Visme's clients after switching from PowerPoint.

Visme’s interactivity feature was a game changer for WOW! and one of the primary reasons they chose Visme.

“Previously we were using PowerPoint, which is fine, but the interactivity you can get with Visme is so much more robust that we’ve all steered away from PowerPoint.” - Kendra, L&D team, Wow!

Visme’s interactive feature allowed them to animate their infographics, include clickable links on their PowerPoint designs and even embed polls and quizzes their employees could interact with.

By embedding the slide decks, infographics and other training materials WOW! created with Visme, potential customers get a taste of what they can create with the tool. This is much more effective than describing the features of Visme because it allows potential customers to see the tool in action.

To top it all off, this case study utilized relevant data and figures. For example, one part of the case study said, “In Visme, where Kendra’s team has access to hundreds of templates, a brand kit, and millions of design assets at their disposal, their team can create presentations in 80% less time.”

Who wouldn't want that?

Including relevant figures and graphics in your case study is a sure way to convince your potential customers why you’re a great fit for their brand. The case study template below is a great example of integrating relevant figures and data.

This colorful template begins with a captivating headline. But that is not the best part; this template extensively showcases the results their customer had using relevant figures.

The arrangement of the results makes it fun and attractive. Instead of just putting figures in a plain table, you can find interesting shapes in your Visme editor to take your case study to the next level.

5. Lyte Reduces Customer Churn To Just 3% With Hubspot CRM

While Lyte was redefining the ticketing industry, it had no definite CRM system . Lyte utilized 12–15 different SaaS solutions across various departments, which led to a lack of alignment between teams, duplication of work and overlapping tasks.

Customer data was spread across these platforms, making it difficult to effectively track their customer journey. As a result, their churn rate increased along with customer dissatisfaction.

Through Fuelius , Lyte founded and implemented Hubspot CRM. Lyte's productivity skyrocketed after incorporating Hubspot's all-in-one CRM tool. With improved efficiency, better teamwork and stronger client relationships, sales figures soared.

The case study title page and executive summary act as compelling entry points for both existing and potential customers. This overview provides a clear understanding of the case study and also strategically incorporates key details like the client's industry, location and relevant background information.

Having a good summary of your case study can prompt your readers to engage further. You can achieve this with a simple but effective case study one-pager that highlights your customer’s problems, process and achievements, just like this case study did in the beginning.

Moreover, you can easily distribute your case study one-pager and use it as a lead magnet to draw prospective customers to your company.

Take a look at this case study one-pager template below.

This template includes key aspects of your case study, such as the introduction, key findings, conclusion and more, without overcrowding the page. The use of multiple shades of blue gives it a clean and dynamic layout.

Our favorite part of this template is where the age group is visualized.

At first, Workato searched for a simple scheduling tool. They soon discovered that they needed a tool that provided advanced routing capabilities based on zip code and other criteria. Luckily, they found and implemented Chili Piper.

As a result of implementing Chili Piper, Workato achieved a remarkable 75–80% conversion rate and improved show rates. This led to a substantial revenue boost, with a 10-15% increase in revenue attributed to Chili Piper's impact on lead conversion.

This case study example utilizes the power of video testimonials to drive the impact of their product.

Chili Piper incorporates screenshots and clips of their tool in use. This is a great strategy because it helps your viewers become familiar with how your product works, making onboarding new customers much easier.

In this case study example, we see the importance of efficient Workflow Management Systems (WMS). Without a WMS, you manually assign tasks to your team members and engage in multiple emails for regular updates on progress.

However, when crafting and designing your case study, you should prioritize having a good WMS.

Visme has an outstanding Workflow Management System feature that keeps you on top of all your projects and designs. This feature makes it much easier to assign roles, ensure accuracy across documents, and track progress and deadlines.

Visme’s WMS feature allows you to limit access to your entire document by assigning specific slides or pages to individual members of your team. At the end of the day, your team members are not overwhelmed or distracted by the whole document but can focus on their tasks.

While pandemics don't happen every day, you can look through your customer’s journey and highlight a specific time or scenario where your product or service saved their business.

The story of Vogmask and Rush Order is compelling, but it simply is not enough. The case study format and design attract readers' attention and make them want to know more. Rush Order uses consistent colors throughout the case study, starting with the logo, bold square blocks, pictures, and even headers.

Take a look at this product case study template below.

Just like our example, this case study template utilizes bold colors and large squares to attract and maintain the reader’s attention. It provides enough room for you to write about your customers' backgrounds/introductions, challenges, goals and results.

The right combination of shapes and colors adds a level of professionalism to this case study template.

8. AMR Hair & Beauty leverages B2B functionality to boost sales by 200%

With limits on website customization, slow page loading and multiple website crashes during peak events, it wasn't long before AMR Hair & Beauty began looking for a new e-commerce solution.

Their existing platform lacked effective search and filtering options, a seamless checkout process and the data analytics capabilities needed for informed decision-making. This led to a significant number of abandoned carts.

Upon switching to Shopify Plus, AMR immediately saw improvements in page loading speed and average session duration. They added better search and filtering options for their wholesale customers and customized their checkout process.

Due to this, AMR witnessed a 200% increase in sales and a 77% rise in B2B average order value. AMR Hair & Beauty is now poised for further expansion and growth.

9. How a Marketing Agency Uses Visme to Create Engaging Content With Infographics

SmartBox Dental , a marketing agency specializing in dental practices, sought ways to make dental advice more interesting and easier to read. However, they lacked the design skills to do so effectively.

Visme's wide range of templates and features made it easy for the team to create high-quality content quickly and efficiently. SmartBox Dental enjoyed creating infographics in as little as 10-15 minutes, compared to one hour before Visme was implemented.

By leveraging Visme, SmartBox Dental successfully transformed dental content into a more enjoyable and informative experience for their clients' patients. Therefore enhancing its reputation as a marketing partner that goes the extra mile to deliver value to its clients.

For example, this case study highlighted Visme’s collaboration tool . With Visme’s tool, the SmartBox Dental content team fostered teamwork, accountability and effective supervision.

Visme also achieved a versatile case study by including relevant quotes to showcase each tool or feature. Take a look at some examples;

Visme’s collaboration tool: “We really like the collaboration tool. Being able to see what a co-worker is working on and borrow their ideas or collaborate on a project to make sure we get the best end result really helps us out.”

Visme’s library of stock photos and animated characters: “I really love the images and the look those give to an infographic. I also really like the animated little guys and the animated pictures. That’s added a lot of fun to our designs.”

Visme’s interactivity feature: “You can add URLs and phone number links directly into the infographic so they can just click and call or go to another page on the website and I really like adding those hyperlinks in.”

You can ask your customers to talk about the different products or features that helped them achieve their business success and draw quotes from each one.

Jasper, an AI writing tool, lacked a scalable content strategy to drive organic traffic and user growth. They needed help creating content that converted visitors into users. Especially when a looming domain migration threatened organic traffic.

To address these challenges, Jasper partnered with Omniscient Digital. Their goal was to turn their content into a growth channel and drive organic growth.

37 Product Analyst Interview Questions in 2024

Introduction.

A product analyst is a hybrid role between a data analyst and a business analyst. At its core, product analysts work cross-functionally with other teams to bring new products to the market by using data to drive decision making.

Product analyst interview questions assess the unique skill set needed to pull this balancing act off. You can expect plenty of data analytics questions - namely SQL writing and statistics - as well as business/product sense questions. These interviews are designed to test your ability to use data in making sound product decisions.

Product Analyst Interviews: What Questions Get Asked?

Product analyst interviews vary by company. However, after analyzing more than 15,000 product analyst interview experiences, we know the most commonly asked topics are product metrics case studies, SQL questions, and data analytics:

• Product Case Study Questions - These questions ask you to evaluate new features and improve existing products.
• SQL Questions - You will be asked to write SQL code to query and manipulate large databases.
• Analytics Questions - Analytics questions test your ability to generate actionable insights from data.
• A/B Testing / Experimentation Questions - These questions relate to running experiments and understanding tradeoffs.
• Python Questions - You will be asked to write Python code to manipulate data and write scripts for analysis.
• Statistics and Probability - These questions are asked to assess your understanding of statistical concepts needed to analyze large data sets.
• Behavioral Questions - These questions focus on projects, your work experience, resume and communication skills.

What Is the Interview Process for Product Analysts?

Product analyst interviews typically include 3-5 rounds that assess your technical skills, product intuition, and ability to communicate. Google Product Analyst interviews , for example, include three rounds:

Step 1: Recruiter Screen

The majority of tech companies use recruiter screens as a first step. This provides the recruiter the chance to get to know the candidate and understand if the candidate is right for the role, assess communication skills and see if the candidate has a genuine interest in the role.

Step 2: Technical Screen

A technical round assesses your technical skills. Specifically, SQL and product intuition are tested during this round. You will be asked to write SQL queries and functions to solve problems.

You can also expect product case study and metrics questions. These questions ask you to analyze data and use that analysis to answer questions about a product.

Step 3: On-Site Round

During the on-site round, you can expect more technical and product rounds. Many companies also do a one-on-one with the product manager (PM). This interview assesses your knowledge of the product, and to see if your product intuition is a strong match.

Product Case Study Questions

Product case study questions assess your ability to use data to influence product decisions. Typically, these questions ask about feature changes, metrics anomalies, measuring product success and/or product improvements.

1. How would you determine why the number of comments per user is decreasing at a social media company for the last three months?

To add context on why the question is being posed, even though comments per user is decreasing, overall the company has been consistently growing users month-over-month for three months.

• Jan: 10000 users, 30000 comments, 3 comments/user
• Feb: 20000 users, 50000 comments, 2.5 comments/user
• Mar: 30000 users, 60000 comments, 2 comments/user

Using this model, you might also model churn as Month 1 - 25%, Month 2 - 20% and Month 3 - 15%. Knowing that some users are churning off the platform each month, what can you infer about the decrease in comments per user?

2. What’s the first change you would make or new feature that you would add to product X?

Interviewers ask this question to see that you have done your research and have knowledge of the company’s products. In particular, they want to know:

• If you understand what the product is and its features.
• If you understand who the target audience is.
• If you recognize the problem the product solves for the audience.

Prior to the interview, create some answers for a question like this. In particular, you should propose changes or new features that will enhance the product, address a problem and align with the company’s overarching objectives.

3. How can you use the Facebook app to promote Instagram?

This product question is more focused on growth and is actively in Facebook’s growth marketing analyst technical screen. With growth questions, we have to come up with solutions in the form of growth ideas and provide data points for how they might support our hypothesis.

One hypothesis we could propose is that implementing notifications to Facebook users of friends that have joined Instagram would help to promote Instagram. So if a user’s friend on Facebook decides to join Instagram, we could send a notification to the user that their friend joined Instagram. We can test this hypothesis by implementing an A/B test . We can randomly bucket users into a control and test group where the test group gets notifications on Facebook each time their friend joins Instagram, while the control group does not. At the end of the test, we can observe the sign-up rate on Instagram between the two groups.

4. You have ten experiment ideas for improving conversion rates on an ecommerce website. How do you choose which ideas to test?

One of the most effective ways is to conduct quantitative analysis. You can measure the opportunity size of each idea using historical data.

For example, if one of the ideas was to introduce cart upsells, you could analyze the number of multi-item orders historically. If only a small percentage of customers purchase multiple items, introducing upsells would be a sizable opportunity. You might then choose an A/B test related to cart upsells.

5. Which variables might Uber use to estimate pick-up ETA, besides the ETA from the GPS system?

With metrics questions, start by listing broad variables that could affect ETA. In this case, that would include things like:

• Driver speed - Some drivers may be faster than others.
• Finding the passenger - Locations that experience large crowds would make it harder to locate a passenger.
• Weather conditions - Poor weather conditions could slow pick-up times.
• Wrong turn rates - An area where drivers are prone to wrong turns could slow pick-up times.
• Construction Seasonality - Construction and street/housing improvement projects tend to occur at higher rates during certain times of year, and could impact road access in high density areas.

Once you’ve created a list of broad variables, you can then start to go deeper and choose which ones might have the greatest effect. Weather, how crowded a location is, and wrong turn rate could all help to improve the accuracy of the ETA model.

6. How would you decide whether updating the permanent deletion rate of Dropbox’s trash feature is a good idea?

Let’s say that Dropbox wants to change the logic of the trash folder from never permanently deleting items to automatically deleting items after 30 days. How would you validate this idea?

See a step-by-step solution to this question on YouTube:

7. How can we measure Netflix’s success in acquiring new users through a 30-day free trial?

More context. Let’s say at Netflix we offer a subscription where customers can enroll for a 30-day free trial. After 30 days, customers will be automatically charged based on the package selected, unless they opt out. What metrics would you look at?

First step, think about Netflix’s business model. They want to focus on:

• Acquiring new users to their subscription plan.
• Decreasing churn and increasing retention.

How would this free-trial plan affect how Netflix might acquire new users or manage their customer churn?

SQL Product Analyst Questions

The types of SQL questions in product analyst interviews range from definition-based discussions, e.g. “When would you use DELETE vs TRUNCATE?” , to writing queries based on provided data. Multi-step SQL case studies are also common. These questions ask you to propose metrics, and then write SQL to pull those metrics.

8. What is the difference between the WHERE and HAVING clause?

Both WHERE and HAVING are used to filter a table to meet the conditions that you set. The difference between the two is shown when they are used in conjunction with the GROUP BY clause. The WHERE clause is used to filter rows before grouping (before the GROUP BY clause) and HAVING is used to filter rows after grouping.

9. What are the different types of joins? Explain them.

There are four different types of joins:

• Inner join: Returns records that have matching values in both tables
• Left (outer) join: Returns all records from the left table and the matched records from the right table
• Right (outer) join: Returns all records from the right table and the matched records from the left table
• Full (outer) join: Returns all records when there is a match in either left or right table

10. How would you isolate the date from a timestamp in SQL?

EXTRACT allows us to pull temporal data types like date, time, timestamp and interval from date and time values.

If you wanted to find the year from 2022-03-22, you would write EXTRACT ( FROM ):

11. Write a SQL query to get the last transaction for each day.

More context. Given a table of bank transactions with columns id , transaction_value , and created_at (date and time for each transaction), write a query to get the last transaction for each day. The output should include the id of the transaction, datetime of the transaction, and the transaction amount. Order the transactions by datetime.

Because the created_at column is in DATETIME format, we can have multiple entries that were created at different times on the same date. For example, transaction 1 could happen on ‘2020-01-01 02:21:47’, and transaction 2 could happen on ‘2020-01-01 14:24:37’.

To make partitions, we should remove information about the time that the transaction was created. But, we would still need that information to sort the transactions

Is there a way you could do both these tasks at once?

12. How do you create a histogram using SQL?

Let’s say you wanted to create a histogram to model the number of comments per user in the month of January 2020. Assume the bin buckets have intervals of one.

A histogram with bin buckets of size one means that we can avoid the logical overhead of grouping frequencies into specific intervals.

For example, if we wanted a histogram of size five, we would have to run a SELECT statement like so:

13. How will you write a query to get the post success rate?

More context. A table contains information about the phases of writing a new social media post. The action column can have values post_enter , post_submit , or post_canceled for when a user starts to write a post (post_enter), successfully posts (post_submit), or ends up canceling their post (post_cancel).

Write a query to get the post success rate for each day in the month of January 2020. You can assume that a single user may only make one post per day.

Let’s see if we can clearly define the metrics we want to calculate before just jumping into the problem. We want the post success rate for each day over the past week. To get that metric let’s assume post success rate can be defined as:

(total posts submitted) / (total posts entered)

Additionally, since the success rate must be broken down by day, we must make sure that a post that is entered must be completed on the same day. What comes next?

14. We have a table that represents the total number of messages sent between two users by date on messenger. What are some insights that could be derived from this table?

In addition to thinking through possible insights, what do you think the distribution of the number of conversations created by each user per day looks like? Write a query to get the distribution of the number of conversations created by each user by day in the year 2020. This visualization can also help you hone the insights to be gleaned.

Data Analytics Questions

Analytics questions are a subset of SQL questions, and often require SQL code writing. These questions assess your ability to pull actionable insights from data. In these questions, you might be asked to pull metrics or perform a multi-step data analytics case study.

15. We have a hypothesis that the Clickthrough Rate (CTR) is dependent on the search result rating. Write a query to return data to support or disprove this hypothesis.

This is a classic data analytics case study type question, in that you are being asked to:

• Create a metric to analyze a problem.
• Pull the metric you created with SQL.

With this question, start by thinking about how we could prove or disprove the hypothesis. For example, if CTR is high when search ratings are high, and low when search ratings are low, then the hypothesis is supported. With that in mind, you can solve this problem by looking at results split into different search ratings buckets.

16. Given three tables representing customer transactions and customer attributes, write a query to get the average customer order value by gender.

Quick solution. For this problem, note that we are going to assume that the question states the average order value for all users that have ordered at least once. Therefore, we can apply an INNER JOIN between users and transactions.

17. Given a table with customer purchase data, write a query to output a table that includes every product name a user has ever purchased.

More context. The products table includes id , name and category_id information for customers. In addition, your output should include a boolean column with 1 if the customer has previously purchased that product category, or 0 if they have not.

Additionally, the table should have a boolean column with a value of 1 if the user has previously purchased that product category and 0 if it is their first time buying a product from that category.

Your output should look like this:

A/B Testing and Experimentation Questions

Product analysts are tested on their ability to design, conduct and evaluate A/B tests. These questions explore A/B testing and statistics, and include definitions-based questions and A/B testing case studies.

18. What is the difference between a t-test and a z-test?

The biggest difference comes down to sample size. Z-tests are best performed when the experiment has a large sample size, while t-tests are best for small sample sizes.

Further, a z-test is a statistical test that is used to determine whether the means of two samples are different, a calculation which requires variance to be known as well as a large sample size. A t-test is a type of statistical test that is used to determine if the means of two samples are different, and the datasets that you have used must follow a normal distribution while potentially having unknown variance.

19. How do you structure a hypothesis for an A/B test?

A question like this assesses your foundational knowledge of A/B testing. A sample response might include that there are three components you need:

• The variable.
• The result.
• A rationale for why the variable produced the given result.

Then, provide an example. If you wanted to know what effect an upsell offer on a cart had on users (more personalized vs. best-sellers), you might say: If we personalize the upsell offer (variable), then customers will convert at higher rates (result), because the personalized upsells are more relevant for the audience (rationale).

20. What types of questions should you ask before designing an A/B test?

This question assesses your ability to design an A/B test. First, ask about the problem the A/B test is trying to solve. This will help you tailor the questions you would ask. Some examples you might use are:

• How big is the sample size?
• Is this a multivariate test?
• Are the control and test groups truly randomized?

21. You are A/B testing a feature to increase conversion rates. The results show a .04 p-value. How would you assess the validity of the result?

Let’s start out by asking some clarifying questions here:

• What details is the interviewer leaving out of the question?
• Are there more assumptions that we can make about the context of how the A/B test was set up and measured that will lead us to discovering invalidity?
• What rephrasing of the question would help us understand more about the problem at hand?

Basically, this type of question is asking: Was the A/B test set up and measured correctly? If it was set up and measured correctly, what could we say about the p-value?

22. How would you measure the impact that financial incentives have on user response rates?

More context. The results of an A/B test show that the treatment group ($10 reward) has a 30% response rate, while the control group without rewards has a 50% response rate. Can you explain why that happened? How would you improve the experimental design?

See a step-by-step solution for this question on YouTube:

Python Interview Questions for Product Analyst

Product analyst interviews may include basic Python questions, especially for coding-intensive roles. In particular, Python questions cover definitions or ask you to perform a basic-to-intermediate coding exercise.

23. What is a split in Python? Why is it used?

A split() is used to separate strings in Python. For example, if the string was “basic python,” the split function would break that into ‘basic’, ‘python’. Here’s an example:

24. Write a Python function to sort a numerical dataset.

25. write a function that can take a string and return a list of bigrams..

At its core, bi-grams are two words that are placed next to each other. Two words versus one word feature in engineering for a NLP model that gives an interaction effect. To actually parse them out of a string, we need to first split the input string. We would use the python function .split() to create a list with each individual word as an input. Create another empty list that will eventually be filled with tuples.

Then, once we have identified each individual word, we need to loop through the list k-1 times (if

k is the amount of words in a sentence) and append the current word and subsequent word to make a tuple. This tuple gets added to a list that we eventually return.

26. Write a function to generate N samples from a normal distribution and plot the histogram. You may omit the plot to test your code.

This is a relatively simple problem because we have to set up our distribution and then generate n samples from it, which are then plotted. In this question, we make use of the scipy library which is a library made for scientific computing.

First, we will declare a standard normal distribution. A standard normal distribution, for those of you who may have forgotten, is the normal distribution with mean = 0 and standard deviation = 1. To declare a normal distribution, we use the scipy stats.norm(mean, variance) function and specify the parameters as mentioned above

Statistics and Probability Questions

Statistics and probability questions are asked to test your data sense, as well as your ability to analyze large datasets. These questions can include basic definitions alongside short statistical problems that require you to make a calculation.

27. How would you explain p-value to a non technical person?

In the simplest terms, p-value is used to measure the statistical significance of a test. The higher the p-value, the more likely you are to accept the null hypothesis (typically that the two variables can be explained by random interaction). A smaller p-value would indicate that there was a statistically significant interaction between the variables, and that you are able to reject the null, which is to say, something more than randomness explains how the variables interact.

28. Determine the cause of drop in capital approval rates.

More Context: Capital approval rates have gone down for our overall approval rate. Let’s say last week it was 85%, but fell this week to 82%, a statistically significant reduction.

The first analysis shows that all approval rates stayed flat or increased over time when looking at the individual products.

• Product 1: 84% to 85% week over week
• Product 2: 77% to 77% week over week
• Product 3: 81% to 82% week over week
• Product 4: 88% to 88% week over week

This would be an example of Simpson’s Paradox, which is a phenomenon in statistics and probability. Simpson’s Paradox occurs when a trend shows in several groups but either disappears or is reversed when combining the data. This is often because the subgroups are offset from each other on the Y-axis, and when aggregated show only the movement between the groups, and not the trends within. For the original example, there could have been quite a few more sales of Product 2, which pulled the overall approval rate down, even though no drop actually occured for the product.

29. Given two fair dice, what is the probability of getting scores that sum to 4? to 8?

This is a simple calculation problem:

There are 4 combinations of rolling a 4 (1+3, 3+1, 2+2): P(rolling a 4) = 3 ⁄ 36 = 1 ⁄ 12

There are 5 combinations of rolling an 8 (2+6, 6+2, 3+5, 5+3, 4+4):

Solution: P(rolling an 8) = 5 ⁄ 36

30. What are the Z and t-tests? What are they used for? What is the difference between them? When should use one over the other?

In the simplest terms, Z-tests and t-tests are statistical tools used to determine if a sample mean is close to a known population mean. Both tests assume the data follows a normal distribution and involve similar hypotheses, but they differ in the probability distribution they use to calculate p-values. Z-tests rely on the standard normal distribution, making them more suitable for large sample sizes where the population standard deviation is known. On the other hand, t-tests use the t-distribution, which has “fatter tails,” making it more appropriate for smaller sample sizes where the population standard deviation is unknown. As the sample size increases, the t-distribution approaches the standard normal distribution.

31. What is an unbiased estimator and can you provide an example for a layman to understand?

In the simplest terms, an unbiased estimator is a statistical tool used to accurately estimate a population parameter. The idea is that, on average, the estimator will give you the correct value of the parameter you’re trying to measure. For example, if you’re trying to determine the average height of people in a city, the sample mean from a well-chosen sample would be an unbiased estimator of the population mean. This means that, if you were to take many different samples, the average of these sample means would converge to the true average height of the entire population, with no systematic overestimation or underestimation.

Product Analyst Behavioral Interview Questions

Behavioral questions are discussion-based, and they are designed to understand if you are the right culture fit for a position. These questions also dig into your past experiences and soft skills. Your responses should reference your work and impact.

32. What are your favorite data visualization techniques?

Before you jump into an answer, work backwards. The best techniques really depend on the data being conveyed. For example, you might choose a donut chart if you’re conveying percentages. Then, provide some examples of your favorite visualizations you have created, what was unique about them, and what techniques you used.

33. What are some of your favorite products and why?

For any product-related role, expect a question like this. First, you want to provide an overview of the product: what it is, key features, etc. Then, explain the problems the product solves for the user (which is you in this case). Finally, explain why the product solves the problem better than competitors.

34. The product manager provides you with unclear directions for a project. What do you do?

If you are given unclear directions, it may be because the PM is not sure how to proceed. First, you might ask some clarifying questions like:

• What is the end goal?
• Are examples available?
• Can you provide some more details?
• What overarching goal is this tied to?

Once you have more information, you can create a plan and run it by the PM, asking for feedback, suggestions or the final green light. A good PM might use your guiding questions to clarify with other stakeholders, so being comprehensive in your probing can create a better result for internal and external partners.

35. How do you stay updated on market trends?

Interviewers ask this question to gauge your passion for analytics and product. To answer, you might talk about:

• Product-related podcasts.
• Blogs or news sources.
• People you follow on Twitter.
• How you gain new skills.
• Interesting case studies you have read.

36. How would you assess the quality of a dataset?

With this question you might talk about performing a data quality assessment and analyzing particular features of the dataset. Some metrics you might be interested in include:

• Completeness
• Consistency

37. What would your first 90 days on the job look like?

Expect a variation of this question. Interviewers ask it to assess your drive and ambition, as well as how fast you can adapt to new situations.

Start with an overview of what you would need. What information would you gather in the first 30 days? How would you familiarize yourself with the product? Then, think about where you might be able to add the most value. If you have deep experience in churn analysis, you could describe jumping into details like analyzing churn, developing predictive models for churn, and identifying opportunities to reduce it.

What Are Product Management Case Study Interviews?

Carlos González De Villaumbrosia

Updated: May 6, 2024 - 10 min read

What is a product management case study interview?

A case study interview, also known as a case interview, is a tool used by many companies to assess a candidate’s analytical, creative, and problem-solving skills. Similar to coding interviews for engineers, they allow the interviewers to simulate a situation that allows your skills to be put into practice.

Quite simply, you’ll be given a situation, and asked to make suggestions or come up with a hypothetical solution or improvement.

In product management, this can be about any number of things. The realm of product managers is vast, and covers many different aspects of product development. As product managers sit at the intersection of business, technology, and design, you could be asked case questions under these umbrellas.

This means that you could be given a case question based on product design, monetization, market research, user segmentation, trends, data, technical development, go-to-market , prioritization…pretty much anything product managers are into!

Example case study interview questions

What’s your favorite product? How would you improve its design?

Which company do you think we should acquire next?

How would you go about launching our product in an emerging market, say, India?

What new feature would you build for Instagram?

How to ace a case study interview

The product design case interview

No, the interview isn't going to hand you a Wacom tablet and ask you to mock up an entire product on the spot! Instead, you’ll be asked to think through some solutions to pretty common design problems. Things like:

How would you improve our in-app messenger?

If we tasked you with making our user interface more inclusive of those with disabilities, how would you approach that?

How would you redesign our homepage to make it more appealing for X demographic?

We’re finding that X number of users don’t make it through the entire onboarding process. What would you do/design to fix that?

The key when being asked a question about how you’d improve the company’s product is not to insult it too heavily. Remember, the people who built it are in the room with you, so if you come in hot with “well, for starters, your homescreen is absolutely hideous and needs a complete do-over”, you’re not going to endear yourself to them. A product manager is a diplomat, so be as diplomatic as possible.

Instead of focusing on how you’d fix what you see as glaring problems, try to come up with something that adds to the product. “I think a chatbot in your user onboarding process would help people to navigate through the process. Here’s where I’d implement it…”

How to ace it

Give your hypothesis: Because everything in product starts with why .

Lay out your approach : Briefly summarize what your approach would be, given your hypothesis. Include things like the research you would need to do, and the preparation the team would need to make.

Identify the user: Companies want user-driven product managers, so definitely make sure you know which user you’re building for.

Describe the solution : How would you actually build the solution? No need to get too technical if that’s not where your skills lie. If that’s the case, talk about how you’d lead the engineering teams to build the solution.

Suggest testing: If you’ve got 2 ideas and you’re not sure which one is better, describe both and talk about the test you’d run to discover which one to roll with.

Prioritize features : Show off your prioritization skills if you’re suggesting more than one feature.

Suggest features for an MVP and plans for a V1 launch:

Finish off by helping the interviewers to visualize what the finished MVP would be like, as well as the plans you’d have for a full release later down the line.

The business-thinking case interview

Business thinking is vital for product managers, as you’re the person that ties what’s being built to the needs of the business. This is why you may be presented with a business problem, so that the interviewer can assess your thought process, and how you approach product strategy.

Business case questions may include things like:

Management wants to build X because a competitor has launched something similar. How would you respond?

If we wanted to move more into the B2B market by launching X, what would you do first?

How would you increase customer adoption for the feature we released last month?

We want to become more product-led in our growth strategy. What recommendations would you make in terms of pricing structure/increasing customer adoption?

Establish market characteristics : This is especially important if your case question is a go-to-market question. If you’re not sure what the market characteristics are, talk about what you would find out before starting the work.

Layout your approach: Briefly summarize what your approach would be.

Prioritize your actions: If you’ve been asked for a step-by-step approach, talk about why you’re doing things in that order.

Provide analysis : Business decisions require a heavy amount of analysis, so be sure to include some competitor/customer/market analysis.

Make recommendations: Talk about the end result in a business sense. Instead of getting into the weeds of feature building etc, give a step-by-step approach of how you’d take a new feature to market, or make business-oriented improvements to a product.

Remember that a business-thinking case question requires an answer that would make C-suite happy. Try to think through your answer for the eyes of management. Think about what brings most business value, and tailor your answer around that.

The technical interview

Here, by technical interview, we don’t necessarily mean the tech interviews that engineers can expect to go through. It’s very rare for product managers to be asked technical questions in an interview, unless they’re specifically applying for a technical product manager role. You’ll usually get some warning in advance that your technical prowess will be tested, either by the recruiter or a hiring manager.

The chances of being given an in-depth technical case interview (aka, a coding interview) are rare, so you’re more likely to be asked a few general questions to gauge your technical ability.

Things like:

What’s your experience with X or Y technology?

Do you feel comfortable managing a team of engineers?

Can you explain the most technical project you’ve worked on?

These are questions that you should be able to answer in the room, because they’re based on your direct experience. So you don’t need to put any special level of preparation into their answers.

You may also be asked some technical questions that allow you to show off your technical knowledge, but are open-ended enough that you can still answer even if you’re not very techy. The goal is to gauge how much technical know-how you already have, not to embarrass you and put you on the spot for not having a computer science degree.

These questions might include:

What feature do you think we should build next? How should we approach building it?

Would you build X solution in-house, or would you outsource development elsewhere?

What partners do you think we should integrate with next? (eg. Slack, Trello)

These are questions that you can approach in your own way, from a technical perspective if you come from that background, or from a people-management/design/business perspective if you don’t.

Product managers and tech skills…what’s the deal?

It’s highly unlikely that you’ll be asked to go through a technical interview, as product managers aren’t the ones who physically build the product. They provide the direction and the insights, and the engineers provide the solutions and the finished product. So what’s gained by seeing how well you can code?

Well, some roles are more technical than others, so obviously in these roles you’d need either a computer science degree or a proven record of technical work, like an engineering background.

But for a regular product manager, you’re less likely to be given a technical case interview, and more likely to just be asked a few very general questions to gauge your knowledge.

1. Give yourself time to think

The worst thing you can do is panic, and rush in with an answer. It’s OK to give yourself time to think. An interview is not a first date, and silences don’t have to be awkward! So pause, and give yourself time to consider your answer before you start.

That’s much better than giving a sub-standard answer that you can’t take back. The interviewer will expect you to need a moment to gather your thoughts, so don’t stress.

2. Hack: The McKinsey case study

Now, you’re bound to go off and do plenty more research on case study interviews, wanting to find out everything you can. So let us give you this secret hack: check out materials for McKinsey case interviews .

“But I want to work at Facebook/Google/Amazon!” we hear you say. “Why would I prep for McKinsey?”

McKinsey is one of the most difficult interviewers out there. Reviews by some previous interviewees makes it seem like the process was designed to help choose the next ruler of Westeros. Their standards are incredibly high, and their case interviews are something that people prep weeks, even months in advance for.

This has a double result for you. One, there are swathes of resources out there specifically to prep for this behemoth of a case interview. Two, if you can give a McKinsey-standard answer to a case interview, you’ll outshine the competition easily!

3. Practice ahead of time

While you can’t be totally sure what you’ll be asked in a case interview, you can still prepare.

The smart thing to do is to practice case interview questions ahead of time. The way to do this is to pick apart the job posting you’re interviewing for, and identify what the main responsibilities are.

Case interview preparation is absolutely essential for acing product manager interviews, as you’re bound to be asked a hypothetical question sooner or later in the interview process.

4. Don’t feel pressured to give a perfect answer

Companies know how much time, research, and information goes into making informed product decisions. So if they’ve asked you to propose a new feature for their product as part of your interview, they’re not looking for something they can actually implement from you. They just want to see how you think, and what your analytical and problem-solving skills are. It’s also a test of your communication skills, seeing how you present yourself and your ideas.

So don’t pressure yourself into giving an answer that’s on par with the work their existing product managers do. That’s like beating yourself up for not running as fast a Usain Bolt when you do your first ever 5K.

Product analytics case study: how to measure user retention

About a year ago I started working with a successful wearable-device company. This company hired me to help them with two main challenges:

• Make their organization more data-driven
• Help them better understand their product retention and usage

In this post I'm going to cover how we achieved these goals and how you can do the same for your own organization. The lessons I share in each section are relevant for any organization making significant changes to their BI infrastructure.

My client was kind enough to agree to me writing this case study but I decided to keep their identity private so that I can share as much as I can about the process and what we learnt.

Discovery and data audit

The first step I take when helping a client become more data-driven is to conduct a discovery and data audit .

The main goals of this phase include:

• Learning the business. This includes target market, sales cycle, the product and anything else which may be relevant.
• To get a sense of the existing tools, systems and data.
• To write up a road map, a project list, and any major concerns or road blocks I identify.

I learnt the following information about my client during the discovery phase:

• They sold a wearable-device that synced with your smart phone via an app.
• They had apps for both iOS and android devices.
• They were collecting a lot of data on the usage of their device.
• Their data silos included a MySQL database, Intercom and Firebase analytics.
• There were a number of possible ways to make the company more BI-friendly.

The BI road map for a wearable-device company

After the initial discovery of the business, I was able to draw up a road map for centralizing the companies data in a data warehouse.

The idea is to move all the relevant data into a single data base to make it easy to build dashboards and to conduct analyses. This would allow a quicker delivery time and to allow more individuals to get value from the company's data.

A data warehouse would also make it easy for future analysts to immediately provide value to the company.

An overview of my plan can be seen in the diagram below:

The BI stack that I recommended to my client included:

• Data warehouse : BigQuery
• ETL solution : Stitch
• Event tracking : Segment or Firebase (we ended up sticking with Firebase)
• Dashboarding : Tableau

Key lessons learnt during the discovery phase:

• The costs involved and available budget are the two most critical variables that need to be discussed at this stage. Implementing BI infrastructure is costly and a long-term investment.
• There were a number of nuances related to Firebase that needed further investigation. We didn't want to leave any doubt in our plan and I conducted a lot of research on the limitations of Firebase. In the end Firebase was more than what we needed and since it was free, we stuck with it.

Data silos and BI stack

My client had their product data spread out in a number of different data silos. These included a MySQL database, Intercom and Firebase. At a later stage a MongoDB was also introduced which added complications.

Since Firebase would act as our event tracking solution, and it has its own integration with BigQuery, I decided to go with BigQuery as our data warehouse.

The challenge was to move the MySQL, MongoDB and Firebase data into BigQuery.

We managed to move these sources into BigQuery by using a combination of ETL scripts that we wrote and Stitch . Before we started moving these sources into BigQuery we made sure to set up a replication process so that the scripts and Stitch were not running on the production databases.

We were able to easily push the Firebase events into BigQuery by using the native integration between the two tools.

One major advantage of BigQuery is the ease of creating views. Once I had all the data silos in BigQuery I could build smart tables made up of data from numerous sources.

One example of such a table is the "master users" table. This table includes user properties and aggregations from all the data sources. Each row represents a user and the columns represent user-specific information. This table would become central in all the dashboards I built for the product team.

Key lessons learnt during the implementation phase:

• It was very helpful to have a point of contact within R&D. After completing a few of these projects, I'd say that it is critical to have one person in R&D that can work with the analyst / BI consultant.
• A few months after starting the process the company made a major change to their back-end. This created a ton of issues with the road map and a lot had to change. One change was adding MongoDB to the tech stack. MongoDB is not very BI-friendly. We worked through these changes and adapted.

Setting up Tableau

A critical piece of the BI puzzle is data visualization. A data warehouse provides a ton of value to analysts but in order to share that value, you need dashboards. Tableau is my first choice and thankfully my client trusted my decision to go with Tableau.

One major decision that needs to be taken when setting up Tableau is to go with Tableau Online or Tableau Server. There are a number of pros and cons with each which I've covered in detail in this introductory post to Tableau .

In order to speed up the process and eliminate reliance on R&D we went with Tableau Online. We started with a single license of Tableau Online and Tableau Desktop.

We introduced Tableau on day 1 because I was able to connect to replicas of the data silos and conduct analyses for my client.

I was able to answer key questions relating to retention by accessing usage data and working with it in Tableau Desktop.

Retention and usage dashboards

Once the initial data was being pushed into BigQuery I as able to focus my energy on building robust dashboards for the product team.

Below are some screenshots of some of the dashboards I built for my client.

Notice the user-level filters like gender and age. Since all of our product data is in one database, BigQuery, it is easy to blend it with usage and retention data and then build very robust dashboards.

Key lessons learnt during the dashboard building phase:

• It took time for me to understand the style of data visualizations the key consumers preferred. I've learnt to take my time with building dashboards and work as closely as I can with the consumers.
• Training and follow ups are also critical to improving adoption of dashboards.

When my client hired me 12 months ago they needed help better understanding their product retention and usage.

Today the product team has a number of powerful dashboards that they use to track key KPIs and answer ad-hock questions on their own.

Their data warehouse continues to scale as does their user base and the foundation is in place to quickly analyze their product and users in the form of analyses or dashboards.

The head of product and his product manager are using these dashboards to frequently update the CEO and other executives in the organization. Overall everyone in the company is smarter when it comes to understanding how people are using their device and mobile apps.

Thanks for reading.

Product case studies are an important tool that businesses use to showcase their products and demonstrate their value. They are especially crucial for companies that have innovative and complex products that require explanation and demonstration to potential customers. A product case study can help potential customers to understand a product's features, benefits, and the results they can expect when using it. In this article, we will explore the importance of product case studies, how to identify the right products for case studies, tips for creating compelling case studies, and best practices for promoting them.

Why Product Case Studies are Important for Businesses

Product case studies provide businesses with a platform to showcase their products in a real-life scenario and demonstrate how they solve customers' problems. By doing so, businesses can communicate the value of their products to potential customers and build trust with them. According to a study by MarketingSherpa, 71% of B2B buyers read case studies during their decision-making process, making them a highly effective marketing tool. Case studies provide social proof and credibility that inspire others to use the product and generate leads. Additionally, product case studies can be repurposed into blog posts, website pages, social media posts, and email marketing campaigns, giving businesses an ongoing source of content to engage their audiences.

How to Identify the Right Products for Case Studies

The first step in creating a successful product case study is identifying the right product to showcase. The ideal product is one that solves a problem that your ideal customer faces, has unique features that set it apart from competitors and generates positive results. It's important to consider the availability of resources, such as time, budget, and personnel. You also need to assess how representative the product is of your business's value proposition and goals. Finally, consider the potential impact of the case study and how well it aligns with the target audience's interests.

Tips for Choosing the Best Format for Your Product Case Study

The format of your product case study will depend on the product, audience, and objective of your study. Common formats include written case study, video case study, podcast case study, and presentation format. The chosen format should match the objectives of your study, the target audience's preferences, and your available resources. The format should be well-designed, clear, persuasive, and include all relevant information that the reader or viewer needs to know about the product.

Elements of a Compelling Product Case Study

Effective product case studies share certain elements that make them compelling to readers and viewers. The elements include the background of the company and customer, the problem or pain point that the customer faced, the solution offered by the product, the implementation and usage of the product, and the results achieved by the customer. A good product case study should be well-structured, engaging, and informative. It should have a clear and concise message, a call to action, and be supported by data and quotes from the customer or expert.

Steps to Creating a Successful Product Case Study

The process of creating a successful product case study encompasses various steps that businesses should undertake. The first step is to identify the product, identifying the customers who use it and their needs. The second step is to collect data by researching, interviewing customers and experts. The third step is to create a structure or outline that guides the case study, including the key elements mentioned above. The fourth step is to draft the case study, edit it, and get feedback from customers and experts. Finally, businesses should promote the case study to their ideal audience through multiple channels.

Real-life Examples of Successful Product Case Studies

There are numerous examples of successful product case studies that businesses can use to inspire their strategies. One example is the Dropbox case study, a written case study that showcases Dropbox's product's integration with other services, cost savings for businesses, and customer feedback. Another example is the Hubspot case study, a video case study that focuses on the customer's business challenges, the solution, and the results achieved by their partnership with Hubspot. These case studies are well-written, engaging, and informative, providing valuable insights for potential customers.

How to Measure the Success of Your Product Case Study

After creating and promoting a product case study, it's essential to track its success to improve future strategies. Metrics such as the number of views, engagement, clicks, leads generated, sales, and customer retention rate can provide insights into the case study's effectiveness. Additionally, reviewing customer feedback such as testimonials, ratings, and reviews can give businesses valuable insights into the impact their product case study had on customers.

Best Practices for Promoting Your Product Case Studies

After creating a product case study, it's critical to promote it to reach your ideal audience effectively. Best practices for promoting your product case studies include using multiple channels such as social media, email marketing campaigns, press releases, website pages, blog posts, and paid advertising. Additionally, segmenting the audience based on their interests and preferences can increase engagement and lead generation. Finally, businesses should measure and analyze the metrics to adapt their strategies based on the case study's feedback.

Common Mistakes to Avoid in Creating Product Case Studies

Creating compelling and effective product case studies can be challenging, and it's essential to avoid common mistakes that can hinder their impact. Common mistakes include failing to target the right audience, not having a clear message or value proposition, making the case study too sales-oriented, or lacking concrete data and statistics. It's crucial to have a thorough understanding of the product, the customers, and their needs, and providing an objective evaluation of the results to avoid these pitfalls.

How to Use Customer Feedback in Your Product Case Studies

Customer feedback is an essential source of insights for businesses that want to create engaging and effective product case studies. The feedback can be collected through customer satisfaction surveys, interviews, and reviews. By incorporating customer feedback in product case studies, businesses can improve the credibility of the study, provide social proof and build trust with potential customers. Additionally, customer feedback can help businesses to improve their products, services, and marketing strategies based on customer needs and preferences.

The Role of Storytelling in Creating Effective Product Case Studies

Storytelling is a powerful tool in creating compelling and persuasive product case studies. By telling the customer's story, businesses can connect emotionally with potential customers and demonstrate the benefits, value, and relevance of the product. Storytelling can also make the case study more engaging, memorable, and relatable. The story format can help simplify complex concepts and make it easier for customers to understand the product's features and benefits.

Tips for Conducting Interviews with Customers and Experts for Your Product Case Study

Conducting interviews with customers and experts is a crucial step in creating accurate and informative product case studies. Tips for conducting successful interviews include preparing a structured agenda or script, identifying the right experts and customers, asking open-ended questions, listening actively, taking detailed notes, and following up after the interview. By conducting thorough and well-prepared interviews, businesses can gather valuable insights, quotes, and data that can help shape the product case study effectively.

How to Incorporate Data and Statistics in Your Product Case Study

Data and statistics can provide valuable insights that justify the value and impact of the product being showcased in the case study. When incorporating data and statistics in a product case study, it's essential to use credible and reliable sources, present the data in a clear and concise format, and link the data to the customers' needs and challenges. Data and statistics can also help businesses to identify trends and patterns in their customer behavior and preferences, leading to better marketing strategies and product development.

The Benefits of Using Video in Your Product Case Study

Video is a powerful and engaging format that can increase the impact and reach of product case studies. Video case studies can offer a more immersive and engaging experience for potential customers, allowing them to see the product's features, benefits, and value in action. Video case studies can also be easily shared across multiple social media platforms, generating greater brand awareness and recognition. Additionally, video case studies can provide visual data, graphs, and diagrams that can be more impactful than written or spoken testimonies.

How to Leverage Social Media to Amplify your Product Case Study

Social media is a powerful tool that can be used to amplify the reach and engagement of product case studies. Tips for leveraging social media include identifying the right social media platforms, creating shareable content that resonates with the audience, using relevant hashtags, tagging influential people in the industry, and promoting the content to targeted audiences. Social media can also be used to generate feedback, encourage testimonials, and gain insights into customers' views and opinions.

The Importance of A/B Testing in Optimizing your product case study

A/B testing can provide valuable insights into how potential customers interact with product case studies and what elements are most persuasive. A/B testing involves creating two versions of the product case study, each with a slightly different element, such as colors, headlines, or calls to action. By measuring how customers interact with each version, businesses can identify which elements are most effective and optimize the case study accordingly. A/B testing can lead to increased engagement, conversion rates, and customer satisfaction.

Best practices for collecting qualitative data through surveys and interviews

Collecting qualitative data through surveys and interviews is a valuable source of insights for product case studies. Best practices for collecting qualitative data include creating a structured interview process or survey, identifying the right questions, avoiding leading questions, listening actively, encouraging detailed responses, and using open-ended questions. Additionally, businesses should ensure confidentiality and anonymity to encourage honest and objective feedback from customers and experts.

Top mistakes businesses make when creating product case studies

Creating effective and compelling product case studies can be challenging, and businesses can make common mistakes that can hinder their impact. Common mistakes include not targeting the right audience, failing to have a clear message or value proposition, making the case study too sales-oriented, and lacking concrete data and statistics. It's crucial to have a thorough understanding of the product, the customers, and their needs, and providing an objective evaluation of the results to avoid these pitfalls.

The role of branding in creating an effective product case study

Branding plays a crucial role in creating an effective and persuasive product case study. The case study should reflect the brand identity and voice, including logos, fonts, and colors. It should also align with the target audience's preferences and interests and embody the brand's values, mission, and vision. An effective product case study should differentiate the brand from competitors and communicate the unique selling proposition. Lastly, brand consistency should be maintained across all channels and formats used to promote the case study.

Product Management Case Study Interview Preparation Guide

Preparing for a product management case study interview can seem daunting. With the right preparation strategy, anyone can master this critical PM interview component.

First, we'll demystify case study interviews and their role in assessing PM candidates. Then you'll learn step-by-step techniques to solve case studies, along with sample responses. By the end, you'll have a game plan to confidently showcase your product thinking.

Introduction to Product Management Case Study Interviews

Product management case study interviews are an important part of the interview process for aspiring product managers. In these interviews, candidates are presented with a business case scenario and asked to analyze the situation, identify key issues, and propose data-driven solutions.

Preparing for PM case study interviews requires dedicating time to understand what these case studies entail, as well as practicing sample cases. With the right preparation, candidates can confidently demonstrate their skills in areas like product strategy, analytical thinking, and communication.

Understanding the Role of Case Studies in PM Interviews

Product management case studies aim to simulate real-world scenarios a PM could face. Interviewers use case study questions to evaluate how candidates would:

• Analyze ambiguous business situations
• Identify the key issues and problems
• Research potential solutions
• Use data and metrics to support decisions
• Communicate recommendations effectively

Essentially, case study interviews enable hiring managers to assess if a candidate can think strategically and make product decisions like an experienced PM.

Rather than testing specific subject knowledge, case studies evaluate a candidate's structured problem-solving abilities. Preparing for these interviews is therefore critical for aspiring product managers.

The Importance of Preparation for Product Management Success

Taking time to prepare for PM case studies interviews is an investment that pays dividends in the long run. Preparation builds three key success skills:

• Structured analytical thinking: Practice analyzing sample cases to develop a methodical approach to solving problems. Break down issues, research multiple solutions, use data to decide, and clearly communicate recommendations.
• Product management knowledge: Understand PM strategy frameworks to analyze case details from a product perspective. Recognize how elements like market conditions, user needs and tech constraints affect product decisions.
• Communication abilities: Construct logical narratives that explain your analysis and recommendations. Prepare to answer follow-up questions on the feasibility, impact and priorities of your proposed solutions.

With these core skills developed through case study preparation, candidates can tackle product management roles with the strategic thinking required to succeed. The time invested is well worth the career advancement and leadership opportunities that follow.

Dissecting Product Management Case Study Interview Questions

Product management case study interviews aim to evaluate a candidate's analytical thinking, problem-solving abilities, communication skills, and overall fit for the product management role. Here are some of the most common types of PM case study interview questions you may encounter:

Challenges in Product Design and How to Navigate Them

Product design case studies focus on the ideation, prototyping, and testing involved in bringing a new product to market. Some examples of product design case study questions include:

• How would you design an app to allow travelers to easily book flights, hotels, rental cars, and other travel arrangements all in one place? Walk through your thought process from idea generation to prototyping and user testing.
• Our company is looking to launch a smart home device. How would you approach the product design process? Outline key considerations around hardware components, software capabilities, target consumer segments, pricing strategy, and go-to-market plan.

To tackle these types of case studies, structure your thought process using a framework like the double diamond design process. Clarify the problem you are trying to solve, ideate potential solutions, describe how you would prototype and test your ideas, and determine how to measure success once launched. Discuss tradeoffs you may need to make regarding features, pricing, and timeline. Provide realistic examples if possible.

Strategizing for Product Success: A Look at Product Strategy Case Studies

Product strategy case studies deal with high-level strategic issues like market positioning, growth opportunities, and competition. Some examples include:

• Our food delivery app has solid market share in urban areas. How would you expand into suburban and rural markets? Consider pricing, driver supply, restaurant availability, and marketing tactics.
• Our e-commerce site seems to have hit a plateau in terms of new customer acquisition. How would you analyze why and determine new strategies for growth?

For these types of case studies, leverage frameworks like Porter's Five Forces to analyze the competitive landscape. Outline the Total Addressable Market (TAM) and serviceable markets to quantify growth potential. Use data to back up your recommendations around pricing, partnerships, marketing channels, and positioning. Discuss risks and provide contingency plans.

Mastering Quantitative Analysis in PM Case Studies

Quantitative PM case studies require breaking down and analyzing numerical data to drive insights and strategy. Examples include:

• Our food delivery app is seeing higher customer churn over the past few months. Based on the provided customer usage data, what insights can you draw about why customers are churning, and what would you recommend to address it?
• We are considering a subscription pricing model for our software rather than a per-seat licensing model. Using the attached financial data, analyze the pros and cons of this pricing change and whether you would recommend for or against it.

For analyzing numerical data, leverage methods like cohort analysis, A/B testing analysis, pricing models, ratio analysis, and forecasting. Structure your thought process, analyze the data to draw insights about root causes, conceptualize solutions or strategic recommendations, and determine how you would measure success if implemented. Quantify the market opportunity and expected business impact to build a compelling case.

Preparing for the variety of PM case studies noted above takes practice over time. Work through examples, learn relevant frameworks, sharpen your quantitative abilities, and hone your communication skills. With diligent preparation, you can master the PM case interview and demonstrate your ability to strategically solve problems.

A Structured Approach to Solving PM Case Studies

A framework all PM candidates should follow when working through a case study.

Clarifying the Case Study Prompt: The First Step to Success

When presented with a product management case study interview prompt, it is crucial to take a moment to clearly understand the key details. This includes clarifying any ambiguous information by asking thoughtful questions of the interviewer.

Be sure to identify the product management case study interview goals and constraints provided in the prompt before beginning your analysis. Understanding these guides will enable you to tailor your response appropriately.

For example, key goals may relate to increasing revenue, improving user retention rates, or reducing customer support cases. Constraints could include budget limitations, technical capabilities, or timelines.

Taking the time upfront to comprehend the case study setup will pay dividends in structuring an effective response later on. Don't rush this step!

Why Structuring Matters: Organizing Your Case Study Response

With a clear understanding of the product management case study interview prompt established, the next step is organizing your response. This is where outlining an agenda slide can be invaluable.

An agenda slide visually sequences the main points you intend to cover in your response. This demonstrates to your interviewer that you can methodically break down the complex problem presented in the case study.

Typically, an effective agenda slide for a PM case study interview will include:

• Clarifying questions
• Key assumptions
• Quantitative analysis
• Qualitative analysis
• Recommendations

Walking through each agenda item in a structured manner lends credibility to your thought process. It also ensures all critical aspects are covered before presenting your final recommendations.

Skipping this organizing step often leads responses feeling disjointed or lacking strategic insight. So take the time to outline your game plan!

Analytical Super Hack: Systematic Analysis for Insightful Conclusions

With your response structured, you can now dive into systematically analyzing the details presented in the product case study examples .

A helpful framework here involves first conducting quantitative analysis based on any numerical data provided - user numbers, conversion rates, revenue metrics, etc. Identify trends in the data and form hypotheses about what could be driving observed outcomes.

Next conduct qualitative analysis based on descriptions of user pain points, customer feedback quotes, persona details, etc. Look for common themes that either validate or disprove your hypotheses.

Finally, synthesize your quantitative and qualitative analyses to uncover powerful insights that will inform your recommended solutions. Don't jump straight to the recommendations without backing them up with analytical rigor!

Following this structured analytical approach demonstrates the strategic thinking and attention-to-detail that PM interviewers are looking for. So don't forget this super hack!

Essential PM Metrics and Concepts for Case Study Mastery

Optimizing user funnels in product management.

Understanding user funnels is critical for product managers. A funnel visualizes the customer journey from initial awareness to becoming an engaged user. Key metrics include:

• Acquisition : The number of new users acquired over a period. This measures the effectiveness of acquisition channels.
• Activation : The percentage of new users who have a meaningful first experience with the product. This indicates whether the onboarding flow is working.
• Retention : The percentage of users who continue using the product over time. This quantifies engagement and stickiness.

To optimize funnels, product managers should:

• Set goals for each metric and prioritize improvements
• Analyze data to identify drop-off points in the funnel
• Run experiments to reduce friction and improve conversion

For example, if activation rate is low, we could A/B test tweaks to the onboarding flow. Getting the funnel right is key for sustainable growth.

The Art of Market Sizing for Product Managers

There are two main approaches to estimating total addressable market (TAM):

• Top-down : Start with the total spending in an industry, then segment by product category and buyer persona. Apply adoption rate assumptions.
• Bottom-up : Identify target customers, understand their spending habits, then extrapolate to the broader market.

For example, a PM could research the pet care industry TAM, narrow to pet insurance, then apply an adoption curve for their specific product. Or survey potential customers on willingness-to-pay.

Being able to accurately size markets helps prioritize opportunities and forecast growth potential. Assumptions should be validated through customer research.

Exploring Monetization Models in Product Management

There are several common monetization models:

• Subscription : Users pay a recurring fee for ongoing access, e.g. SaaS apps. Provides predictable revenue.
• Ad-supported : Free for users, revenue from advertisements. Scales with user base.
• Transactional : Users pay per transaction, e.g. ecommerce. Revenue aligns with usage.
• Freemium : Free tier to acquire users, paid tier for advanced features. Upsell opportunity.

Choosing the right model involves evaluating customer willingness-to-pay, competitive landscape, and marginal costs. Testing pricing sensitivity can optimize monetization strategy.

Understanding monetization early helps build business models that work long-term. Pricing should balance value delivered and market standards.

Mastering the Product Manager Case Study Presentation

Designing impactful product manager case study slides.

When designing slides for a product manager case study interview presentation, focus on creating a logical flow that clearly conveys your thought process.

Here are some tips:

• Lead with the framework. Open by introducing the framework you will use to structure your response (e.g. Market Sizing, 5 Cs, Pros/Cons). This sets expectations.
• Use simple, readable slides. Avoid cramming slides with too much text or complex graphics. Use bullet points, headings, and simple charts to communicate key points.
• Map the framework to slides. Devote individual slides to each part of the framework so your presentation aligns logically.
• Visualize data-driven points. Use basic charts, graphs, or illustrations to visualize market size analyses, financial models, or user research insights.
• Summarize key takeaways. Close by recapping your overall recommendation and next steps in a final summary slide.

Effective Verbal Delivery Techniques for PM Interviews

When presenting your case study analysis, focus on speaking clearly while engaging your interviewer:

• Make eye contact. Look up from your slides frequently and make eye contact with your interviewer rather than reading directly from slides.
• Speak slowly and clearly. Nerves can accelerate speech, so consciously slow your pace. Enunciate words clearly as well.
• Use natural gestures. Use hand gestures and facial expressions to help convey your points rather than stiff body language.
• Gauge reactions and adjust. Observe interviewer reactions and body language. If they seem confused, clarify or provide more context.
• Be conversational. Pose rhetorical questions and speak conversationally rather than a rigid, scripted delivery.

Strategies for Handling Questions During Your Case Presentation

Fielding interviewer questions smoothly will demonstrate knowledge and build credibility:

• Listen fully before responding. Let the interviewer finish the entire question before jumping to reply. Repeat back key parts to confirm understanding.
• Ask clarifying questions if needed. Don't be afraid to ask for clarification if a question is unclear. Break the question down into parts.
• Provide concise yet comprehensive answers. Respond directly and fully while avoiding excessively long answers. Stick to relevant insights.
• Admit if you don't know. Don't try to invent answers. If you truly don't know, say so. Offer related experience or insights that could help.
• Connect answers back to framework. Relate your responses directly back to the parts of the framework covered earlier.

By designing structured slides, delivering insights clearly, and handling questions tactfully, you can showcase your product management skills during case study presentations. With practice, the case interview can become a platform to demonstrate your strategic thinking.

Practice with Real-World Product Case Study Examples

Working through real-world product management case study examples with model solutions is an excellent way to prepare for PM case interviews. Here are two examples to try.

Case Study Example: Food Delivery App Prototype Development

You've been asked to evaluate potential features and conduct usability tests for a food delivery app prototype.

Consider key elements like:

• Onboarding flow
• Menu navigation
• Order placement
• Driver tracking

Develop a prioritized list of features to test based on expected impact and effort required. Outline your usability test approach focusing on:

• Testing environment
• Participant criteria
• Key tasks to evaluate
• KPIs to measure

Provide any other recommendations on how to iterate and improve the app experience.

Case Study Example: Crafting a Growth Strategy for a Social Media Platform

A new social media platform wants to compete with incumbents like Facebook and Twitter.

Outline a strategy focused on:

• Defining the target audience
• Key platform differentiators
• Growth channels to activate
• Engagement and retention tactics

Include quantitative projections on addressable market size and multi-year growth trajectories. Provide examples of tactics to drive growth through both product development and marketing initiatives.

Nonylphenol is a very important product for the chemical industry due to its widespread use as a base for several other chemical products. Among the major industrial sectors that use nonylphenol is the production of non-ionic surfactants, which are used from the home and personal care industry to the agrochemical industry. This study aims to define the optimal or quasi-optimal operating conditions for the separation system, which is composed of packed columns. Using simulation tools, the best operating conditions are attained, and the dinonylphenol subproduct generation is minimized. The commercial simulator Aspen Plus ® was used for this study as the analysis tool for the mentioned objectives. The developed model is validated with technical data, measures are taken in a nonylphenol plant, and parameters are used in the same plant. From the obtained data from the plant, the best process performance is evaluated regarding cost-benefit analysis and safety concerns. The study shows a potential to reduce the subproduct production by 30% and the reboilers’ heat loads by 2%.

1. Introduction

Nonylphenol is a very important reactant in the surfactant industry, and its main application is in ethoxylated non-ionic surfactants, which use about 80% of the produced nonylphenol [ 1 ]. Nonylphenol is produced by a reaction between phenol, nonene, and a basic catalyst. The various nonylphenol applications range from the home and personal care industry to the agrochemical industry.

In chemical terms, nonylphenol is an alkylphenol, hence a phenol derivative where one more hydrogen atom in the aromatic ring is replaced by alkyl radicals. The most important alkylphenols are composed of alkyl radicals that have 2–12 carbon atoms. Besides their use as non-ionic surfactants, alkylphenols are also used as phenolic resins, polymeric additives, and agrochemicals. Nonylphenol is produced from an alkene (nonene) by acid catalysis (Lewis acid or ion-exchange resin), ensuring the replacement of hydrogen by the alkyl radical in the aromatic ring [ 1 , 2 ]. The overall reaction is highly exothermic (−23.7 kcal/gmol) and reversible as presented in Figure 1 .

Nonylphenol synthesis overall reaction.

The overall reaction process synthesizes the isomers ortho-nonylphenol and para-nonylphenol, and the latter is the major product. Besides the main product, the process also produces dinonylphenol as a subproduct, and this occurs by the reaction between one nonylphenol molecule with one nonene molecule. Dinonylphenol is much less used in the chemical industry compared to nonylphenol. Hence, an optimal operating point must be defined to reduce the dinonylphenol production to the minimum possible value because if this subproduct is produced in relatively large quantities, then the plant profit is reduced.

A productive process understanding is required to achieve nonylphenol synthesis optimization. Such understanding is done by theoretical studies that allow technical analysis and plant operation planning. Simulation software is used to evaluate the process under several different conditions without interfering in the plant operation. Moreover, by using simulation software, the optimization studies can be better directed saving time and resources that would be spent if the studies were directed toward a non-optimal configuration.

1.1 Nonylphenol production process

Figure 2 presents the nonylphenol productive process used by a major chemical plant in southeastern Brazil. This particular process consists of the following three major unit operations: reaction, phenol recovery, and nonylphenol purification.

Process flowchart for the nonylphenol production process.

The phenol alkylation reaction occurs in two serial mixture atmospheric reactors and is filled with an acid ionic exchange resin bed. Reactor 1 (R-1) operates within an 80–130°C range, and Reactor 2 (R-2) operates within an 85–135°C range. The temperature increase is gradual and based on the accumulated production of 1°C for each 300 ton of produced nonylphenol [ 3 ]. The reaction feed stream contains a phenol excess. The major raw material cost comes from the nonene purchase; hence nonene is the limiting reactant. The feed stream contains trace amounts of water from the phenol and nonane. The overall formation selectivity is 96.3% nonylphenol, 2.7% dinonylphenol, and 1% heavier compounds [ 2 ].

The process is catalyzed by an acid ionic exchange resin that replaces a Lewis acid. The use of the resin catalyst reduces the raw material demand, yields less subproduct production, and allows better control of mixing parameters. On the other hand, using resin catalyst requires increased capital costs, and the catalyst activity decreases with time. Therefore, reaction control must account for the activity reduction to ensure efficient reactors’ operation.

1.2 Phenol recovery

As the name suggests, this stage aims for the recovery of the unreacted phenol. Distillation is the used separation method. A column (D-1) with structured packing (SULZER BX 50) separates phenol from the heavier compounds in the Reactor 2 (R-2) effluent. The column operating pressure ranges from 0.240 to 0.267 bar. The estimated maximum pressure drop from the bottom to the top is about 0.027 bar. Column D-1 temperature profile lies within the 135°C (top) to 256°C (bottom) range.

Column D-1 feed stream is composed of nonylphenol, dinonylphenol, phenol, nonene, nonane, and traces of water. Since nonane lowers the nonylphenol yield in the reaction process, Column D-1 operates with a partial condenser to separate nonane from the unreacted phenol. The vapor distillate stream is mostly composed of nonane, nonene, and water, while the liquid distillate stream is phenol-rich. The vapor distillate stream is condensed in the Nonane Condenser (E-2), and the outgoing condensed stream goes to storage. The liquid distillate stream is recycled to Tank TK-4 at the beginning of the process, so the recovered phenol is reused in the reaction.

Column D-1 bottom stream is composed of heavier compounds, mainly nonylphenol, and dinonylphenol. As the bottom stream does not meet commercial purity requirements for nonylphenol product, the bottom stream goes to Column D-2 to separate nonylphenol from dinonylphenol.

1.3 Nonylphenol purification

The final stage aims, as previously mentioned, the attainment of nonylphenol products complying with market specifications (minimum 95% purity). The purification is done in Column D-2, which uses structured packing (SULZER BX 50). This column operates at a high vacuum (0.067–0.073 bar). Therefore, the pressure drop in the column must be limited to a maximum of 0.007 bar. Column D-2 operating temperature range is from 216°C (top) to 277°C (bottom).

Nonylphenol at market specification is produced at Column D-2 distillate stream. The purified nonylphenol is then cooled in Exchanger E-6 and stored in Tank TK-7. Therefore, the bottom stream is mainly composed of dinonylphenol, which is also cooled (Exchanger E-7) and stored (Tank TK-8).

2. Packed column and process simulation

In the 1950s, chemical industries used more frequently packed columns as distillation equipment [ 4 ]. Usually, packed columns are used for the separation of mixtures with high relative volatility difference, hence mixtures that are relatively easy to separate [ 5 ].

Packed column interiors are basically completely filled with a packing, which is either packed or random. Unlike a plate column, there is no space between stages, and the only empty spaces in the column are at the top, the bottom, and around the feed stream inlet(s).

Random packing is made up of small components such as Rasching and pall rings. These components have defined dimensions and geometric shapes. The column interior is filled with packing but in a random manner. Hence, the packing distribution varies randomly with the column height.

While random packing does not have a definite design, structured packing is designed to be the same throughout the stage height. Structured packing is usually formed by perforated metallic sheets that have corrugated sections, in order to create multiple parallel channels in the packing. The structured packing design forces the liquid and vapor streams to flow in countercurrent through the channels forming a liquid film in the packing surface. In this manner, contact between the liquid and vapor is maximized in the structured packing [ 6 ].

The main downside of structured packing is the need for a high feed stream flow rate, otherwise, the liquid film formation throughout the column transversal area is compromised. Consequently, low feed stream flow rates can reduce the interphase contact in the column resulting in low-efficiency stages [ 7 ].

Compared to structured packing, random packing has a lower capital cost and is installed more easily. However, structured packing is more efficient regarding distillation and imposes a lower head loss. Moreover, depending on the random packing component distribution, a preferential path can be formed, short-circuiting the column, and drastically reducing column efficiency [ 8 , 9 ].

In packed columns, other internals are essential to avoid a non-uniform distribution, a preferential path formation, or even liquid flowing through the column’s internal wall. Among these internals, the main ones are the distributors and re-distributors [ 8 ].

Considering the nonylphenol production process, packed columns are fundamental for safe and large-scale production as shown in Figure 1 . However, as many thorough locus studies, process optimization finds problems due to plant operation requirements. To perform any study test, plant production can be seriously reduced or even halted, yielding a profit loss. Additionally, relatively drastic alterations in process conditions can compromise the ability of the plant to return to its original operating conditions. Consequently, process simulators can provide tools to investigate different operating conditions, and these simulators are nowadays widely used in chemical industries.

Many process simulators are only able to evaluate a process under a steady state. However, some process simulators can predict the system behavior in a transient state, and this means that the simulator can predict the system behavior when a perturbation occurs. For plants that have different operating regimes, meaning that the process must migrate from one steady state condition to a different one, some transient state process simulators can perform real-time optimization. Such resources enable simulated studies a greater versatility, and a more rigorous evaluation and closer to the system’s actual response. This is crucial for the financial assessment of the productive process [ 10 ].

However, the results attained by a process simulator are only as good as the process model built by the engineers responsible for the process simulation. Therefore, the simulation engineers must have a thorough technical knowledge of the process. This means selecting an accurate thermodynamic model must be selected, the adequate unit operations involved in the process, and also arranging these unit operations to create a coherent productive process. Simulation engineers must also correctly interpret the simulation results, in order to ensure that the simulated model predicts the actual operation with precision.

Nowadays, several chemical process simulators are commercially available or even available for free. Aspen Plus® software from Aspen Tech is one of the main available process simulators. This software has an extensive data bank that includes component parameters and unit operations. Hence, this data bank allows Aspen Plus® to achieve accurate simulation results for many processes, specifically for distillation.

3. Case study: nonylphenol separation and purification

The case study focuses on the nonylphenol-production separation system. Therefore, the study encompasses both the phenol recovery-packed column (D-1) and the nonylphenol purification-packed column (D-2). The system was simulated using Aspen Plus® and is shown in Figure 2 .

For the study development, technical data was obtained from an actual nonylphenol production unit. The data contains information related to the equipment, process operating parameters, and stream composition data, including feed streams’ composition and flow rate. With this information, the flowsheet is built in the Aspen Plus® software. For all the different evaluated conditions, optimization is performed to minimize the dinonylphenol production.

3.1 Simulation development

The first step in building the simulation model involved obtaining actual stream data, specifically Column D-1 feed stream and Column D-2 distillate stream. Additionally, the operating parameters for both columns were investigated. A 3-year time interval for data gathering was established from March 2016 to March 2019. The historical data was supplied by the nonylphenol plant. From the data, the average and the standard deviation were calculated, in addition to assessing superior and inferior limits. Only steady-state operation data was considered, so plant startup and shutdown operation data were disregarded. Table 1 presents the maximum and minimum values for Column D-1 feed stream and Column D-2 distillate stream.

Specification limits for separation system sampling points.

The ideal stream composition is defined to attain the case study objective. This is done by evaluating the periods when dinonylphenol was minimum. The plant production data is available in monthly intervals; thus 3 months were selected as the minimum dinonylphenol-production periods.

3.2 Thermodynamic model

The definition of the selected thermodynamic model for the nonylphenol production system simulation is a crucial step for attaining accurate simulation results. The component’s thermodynamic, kinetic, and transport properties are evaluated using the adequate thermodynamic model [ 11 ]. In this manner, the component mixture thermodynamic relations and liquid-vapor equilibrium condition in the columns are precisely calculated, hence yielding accurate outgoing stream calculations.

Considering that the compounds present in the process are majorly very polar, that no electrolytes are present, and that the operating pressure is lower than 10 bar, the NRTL model was selected. Besides being the appropriate model in the decision tree given by the simulator, previous studies performed by the plant also used the NRTL model, and the results from these previous studies were deemed accurate.

3.3 Distillation column operating data validation

With the selection of the NRTL thermodynamic model, simulations were performed with Aspen Plus® using the columns’ operating date from the unit process flow diagrams (PFD) and equipment data sheet. As these documents also contain the unit material balance for the design condition, this means that the simulation results can be compared with the material balance results.

The packed columns are controlled by the bottom temperature as specified by design. Therefore, this variable was defined as a parameter that must be met by the simulation results. Another important validation point is compliance with the expected outgoing stream composition. In this manner, the nonylphenol in Column D-2 distillate stream must also be met by the simulation results.

For the simulation validation, two situations were considered: comparative evaluation with design conditions and with actual operating conditions obtained from plant instrumentation. For the design scenario, Column D-2 feed and distillate stream compositions are obtained by using the unit material balance, the packed columns’ top and bottom temperatures, the reboilers’ heat loads, and the hot utility flow rate used in these reboilers. For the actual operating scenario, the distillate stream composition is compared with the stream analytical composition measurements, and also by the actual column top and bottom temperature, as well as the measured column temperature profile.

3.4 Operating conditions evaluation

Two operating strategies are feasible to achieve dinonylphenol reduction, which is the study optimization objective. The first strategy consists in reducing the dinonylphenol in the reaction stage. The second strategy is for Column D-2 to produce a distillate stream (nonylphenol product) with the maximum allowable dinonylphenol content. This strategy can be interpreted as contaminating the nonylphenol product to the limit established by market specifications.

Using the 3-month low dinonylphenol yield, the average operating condition values were used as simulation input parameter values. In this manner, it is possible to compare the simulation results of the product outgoing streams for different flow rates. The results define the feed flow rate range that complies with the required production targets, and also the results show how dinonylphenol production varies according to the feed flow rate.

The simulation results also show how the reboilers’ heat loads vary with the feed flow rate. Hence, the hot utility (Thermex) consumption and the resulting operating costs are also evaluated.

3.5 Stream average properties and compositions

Tables 2 and 3 show the main values for the stream operating variables (input and output) for the nonylphenol purification stage. The input variables are used for the simulation model configuration, and the output variables are compared with the simulation results, so the results can be validated.

Average composition for D-1 feed stream and D-2 distillate stream (disregarding water content).

The average composition shown in Table 3 for Column D-1 feed stream was used as simulation input variables. Column D-2 distillate stream composition values are compared with the simulation results. The latter stream average flow rate is calculated for the result comparison. The table shows the production results for the period between 2017 and 2019. Notably, the nonylphenol product stream flow rate shows a decline tendency, since nonylphenol demand has also decreased. For the 3-year period, the average nonylphenol product flow rate is 1195 kg/h ( Table 4 ).

2019 considers the production from January to March, and the projection for the remainder of the year.

3.6 Separation system validation

Table 5 data were obtained from the plant project data. Reflux ratio and reboiler heat input data were obtained from the unit design specifications.

Simulation input data for packed columns D-1 and D-2.

Although the actual Column D-1 condenser is a partial one, the simulation considered a total condenser for simplification purposes. The reason for the use of a partial condenser in column D-1 is for the nonane removal, which was not an objective of the study.

The used structured packing is Sulzer BX 50. The packing was inserted above and below the feed stage. The technical data used in the simulation was also obtained from the unit design data. For Column D-1, the upper part (rectification) packing has a 0.387 m diameter and encompasses Stages 2–4. This part of the column is 1.535 m in height and filled with packing. As for the lower part (stripping), the packing has 0.66 m diameter, and measures 1.345 m of height contemplating Stages 5–7. For Column D-2, the whole vessel has a 0.641 m de diameter. The rectification section is composed of Stages 2–3 and has a height of 0.68 m. The stripping section is composed of stages 4–5 and has a height of 1.195 m.

Thermex is the name of the hot utility used in reboilers. The fluid is the Dowtherm™. A saturated vapor at 280°C, as the design specified. From the fluid data sheet, the latent heat, and the overall heat transfer coefficient were obtained. The Thermex fluid parameter values are given in Table 6 .

Thermex (hot utility) properties.

According to design data, Thermex incoming and outgoing temperatures in the reboilers are equal, and this means that the Thermex vapor is saturated, and only latent is rejected from the hot utility.

Table 7 lists the input data for Column D-1 feed stream in the process simulation for the simulation model evaluation.

Feed stream input data according to design data.

For the first simulation scenario, Column D-1 and D-2 bottom temperatures were set to 256°C and 277°C, respectively. The reboilers’ heat loads were varied so the required separation specification was met. Though the heat load values were kept close to the plant design value. The validation results are given in Table 8 .

Comparison between simulation results and design condition.

temperature variations were calculated using the temperature values in Kelvin.

Overall, the simulator was able to reproduce with good accuracy the actual conditions, although some discrepancies can be observed. Column D-1 bottom presented a very good correlation between simulated and actual data for both major components (nonylphenol and dinonylphenol). However, the simulation yielded a relatively higher phenol content at the bottom compared to the actual data. This occurs as the phenol quantity in the bottom stream is small in absolute numbers both in the simulated results and the actual date. Therefore, small deviations can result in high relative variation. As for Column D-1, both reboiler (E-4) heat load and Thermex flow rate present also low deviation values, 3% and 5% respectively.

For Column D-2 distillate stream, only nonylphenol and nonene presented low relative variation values, and the reason is similar to the one described for Column D-1 bottom stream. An important difference is in the dinonylphenol subproduct stream (bottom), where the simulation yielded a value 68% higher than the actual value. This difference can lead to false optimal points.

For the evaluated production months, Column D-1 feed stream properties are given in Table 9 .

Column D-1 feed stream properties.

Table 10 shows the comparison between simulation results using the D-1 feed stream average flow rate and composition for 2019, and the evaluated 3-month data.

Comparison between simulation results and plant data.

For both the simulation results and the evaluated 3 months, Reactor R-2 effluent stream has a low dinonylphenol content. Hence, D-2 bottom stream (dinonylphenol subproduct) flow rate is small compared to the D-2 distillate stream (nonylphenol product) flow rate. In comparison to Table 3 data, Table 10 shows a significantly lower dinonylphenol content in the D-2 distillate stream. A possible explanation for this difference is that the plant usually operates Column D-2 with a low reflux ratio to deliberately produce a high dinonylphenol content product stream but still in compliance with market demands.

Column D-2 temperature profile is not altered significantly with the flow rate. This is expected as feed composition has a much greater effect on column temperature than feed flow rate. The results prove that as composition varies, temperature varies significantly. Another parameter that has a direct influence on column temperature is the column operating pressure.

As the nonylphenol product becomes purer, the stream’s flow rate decreases. The lower dinonylphenol content in R-2 effluent makes the separation in Column D-2 easier and that can be noted in the lower reflux ratio. Hence, this reduces the plant’s operating cost.

Since composition has a larger effect on column performance than feed flow rate, simulation results are obtained for different dinonylphenol to nonylphenol ratios (DNF). The DNF ratios for the 3 evaluated months are given in Table 11 .

DNF ratio variation for the 3 evaluated months.

In January 2017, the largest DNF ratio variation occurred as the dinonylphenol content in D-2 feed stream reaches the lowest value. This means that for such composition, the D-1 distillate stream already meets market requirements, and this stream could even completely by-pass Column D-2.

3.7 Energy consumption analysis

As columns’ operating conditions are altered, an assessment of the reboilers’ heat loads is made. These heat loads have a direct influence on the hot utility heat load, and also on the financial expenditure to operate the reboilers. Table 12 shows the heat load values per nonylphenol produced.

Simulation results for reboiler heat loads.

For Reboiler E-4, only in March 2019, the heat load surpassed the 2019 average values. For Reboiler E-5, the heat load is lower than the average 2019 value for all months. The same is repeated for the sum of both heat loads.

Therefore, by repeating January 2017 conditions, a 2% energy reduction is attained.

Thermex vapor is generated in a natural gas boiler. The following considerations are made: 100% efficiency in heat transfer from natural gas combustion to Thermex, the natural gas inferior calorific value of 33,500 kJ/m 3 , the natural gas density is 0.7902 kg/m 3 (IEA, 2019), and the natural gas cost is R$2.48/m 3 . Therefore, the heat load cost is 6.29.10 −5 R$/kJ. A financial assessment is made according to the mentioned values and Table 12 values. The results are given in Table 13 .

Expenditure variation for the heat loads’ sum in the 3 evaluated months.

Using the January 2017 value, the expenditure savings in a whole year could amount to R$ 9927.19.

3.8 Minimization of dinonylphenol production

Based on the months when dinonylphenol subproduct stream flow rate was minimal, the operating parameters of the nonylphenol production unit during these months are recommended as operating setpoints. As January 2017 presented the lowest dinonylphenol subproduct stream flow rate, the month’s parameters are given in Table 14 .

Recommended new operating setpoints.

3.9 Analysis of the operating pressure effect

As the purity of distillation column outgoing streams is defined according to process requirements, the distillation column design depends on the definition of two degrees of freedom: the column operating pressure and the reflux ratio (or the number of stages). Column operating pressure influences the equilibrium curve for the heavy and light key components, the column temperature, the condenser and reboiler heat loads, the condenser and reboiler exchange areas, the required utilities, the column diameter, and the column wall thickness, among other factors [ 12 ]. Therefore, defining the pressure is a crucial step in distillation column design.

The greatest challenge in defining the column operating pressure is that there is no established methodology for doing so, instead a handful of heuristics are often used and that can lead to sub-optimal designs [ 13 ]. Thorough optimization studies can be performed to attain a more cost-efficient design [ 14 ] but such studies are not always feasible as many economical parameters can be at the maximum, estimated with a reasonable degree of certainty. Even if the parameters were known, optimizing a distillation column is a time-consuming effort, and depending on the software and hardware used, the obtained solution is likely to be a local optimal and not a global optimal. That does not mean that operating pressure optimization should not be pursued but it means that engineers prefer to use heuristics to quickly attain a solution regardless of whether it is an optimal one or a feasible one.

In spite of optimization study difficulties, project and process engineers must comprehend the operating pressure effects on the distillation column operation. Firstly, relative volatility between light and heavy key components is usually inversely proportional to the operating pressure [ 15 ]. Hence, the lower the column operating pressure is, the higher the relative volatility is, and this means that at lower pressure, separation between key components can be made in fewer stages and with a lower reflux ratio. Evidently, how much pressure affects relative volatility depends on the components being separated. Using Column D-1 feed stream data from Table 7 , the minimum number of stages, minimum reflux ratio, and temperature profiles for Columns D-1 and D-2 are analyzed as a function of the column operating pressure. The results for pressure variation are given in Tables 15 and 16 . For Table 16 , the simulations are made for a D-1 operating pressure of 0.240 bar abs.

Column D-1 operating pressure variation effect.

Column D-2 operating pressure variation effect.

As nonylphenol and dinonylphenol have a considerable difference in molecular weight, and consequently in relative volatility, the results in Tables 15 and 16 show that pressure variation has a small effect on the minimum number of stages and minimum reflux ratio. This small effect is also due to the relatively narrow simulated pressure variation range. As for the columns’ bottom and top temperatures, despite the very low pressures, the temperatures are high. This is expected since dinonylphenol is a large molecule with a very high boiling point. As a suggestion for the plant’s future optimization efforts, operating Column D-1 with an even lower pressure could yield a bottom temperature where Thermex could be replaced with high-pressure steam. As for Column D-2, this is not possible, as this column already operates near full vacuum.

4. Conclusions

The study aimed at subproduct (dinonylphenol) reduction and also heat load reduction. For these aims, a thorough investigation of the design conditions, and historical plant data was made to determine the months that yielded the lowest dinonylphenol production. The plant relies on two strategies to reduce the dinonylphenol production, and these are defining reactor conditions that minimize conversion of nonylphenol into dinonylphenol and increasing dinonylphenol content in the product (nonylphenol) stream to the maximum allowable composition. Aspen Plus® was the simulator used to investigate a new operating condition for the nonylphenol production unit to attain the study goals.

The results indicate that a 36% subproduct reduction is possible. This value is achieved by a comparative analysis between simulation results and data from months where subproduct production reached minimum values. By simulating the nonylphenol plant design conditions, operating parameters are obtained for the reaction, phenol recovery, and nonylphenol purification stages. These recommended parameters are validated using historical plant data. The new simulated condition reduces the reboilers’ heat loads, and this can lead to a 2% reduction in hot utility consumption.
