Case Study Interview Questions About the Customer's Business

Knowing the customer's business is an excellent way of setting the tone for a case study.

Use these questions to get some background information about the company and its business goals. This information can be used to introduce the business at the beginning of the case study — plus, future prospects might resonate with their stories and become leads for you.

• Would you give me a quick overview of [company]? This is an opportunity for the client to describe their business in their own words. You'll get useful background information and it's an easy prompt to get the client talking.
• Can you describe your role? This will give you a better idea of the responsibilities they are subject to.
• How do your role and team fit into the company and its goals? Knowing how the team functions to achieve company goals will help you formulate how your solution involves all stakeholders.
• How long has your company been in business? Getting this information will help the reader gauge if pain points are specific to a startup or new company vs. a veteran company.
• How many employees do you have? Another great descriptor for readers to have. They can compare the featured company size with their own.

Before you can start putting together your case study, you need to ask your customer's permission.

If you have a customer who's seen success with your product, reach out to them. Use this template to get started:

Thank you & quick request

Hi [customer name],

Thanks again for your business — working with you to [solve X, launch Y, take advantage of Z opportunity] has been extremely rewarding, and I'm looking forward to more collaboration in the future.

[Name of your company] is building a library of case studies to include on our site. We're looking for successful companies using [product] to solve interesting challenges, and your team immediately came to mind. Are you open to [customer company name] being featured?

It should be a lightweight process — [I, a product marketer] will ask you roughly [10, 15, 20] questions via email or phone about your experience and results. This case study will include a blurb about your company and a link to your homepage (which hopefully will make your SEO team happy!)

In any case, thank you again for the chance to work with you, and I hope you have a great week.

[Your name]

If one of your customers has recently passed along some praise (to you, their account manager, your boss; on an online forum; to another potential customer; etc.), then send them a version of this email:

Hey [customer name],

Thanks for the great feedback — I'm really glad to hear [product] is working well for you and that [customer company name] is getting the results you're looking for.

My team is actually in the process of building out our library of case studies, and I'd love to include your story. Happy to provide more details if you're potentially interested.

Either way, thank you again, and I look forward to getting more updates on your progress.

You can also find potential case study customers by usage or product data. For instance, maybe you see a company you sold to 10 months ago just bought eight more seats or upgraded to a new tier. Clearly, they're happy with the solution. Try this template:

I saw you just [invested in our X product; added Y more users; achieved Z product milestone]. Congratulations! I'd love to share your story using [product] with the world -- I think it's a great example of how our product + a dedicated team and a good strategy can achieve awesome results.

Are you open to being featured? If so, I'll send along more details.

Case Study Benefits

• Case studies are a form of customer advocacy.
• Case studies provide a joint-promotion opportunity.
• Case studies are easily sharable.
• Case studies build rapport with your customers.
• Case studies are less opinionated than customer reviews.

1. Case studies are a form of customer advocacy.

If you haven't noticed, customers aren't always quick to trust a brand's advertisements and sales strategies.

With every other brand claiming to be the best in the business, it's hard to sort exaggeration from reality.

This is the most important reason why case studies are effective. They are testimonials from your customers of your service. If someone is considering your business, a case study is a much more convincing piece of marketing or sales material than traditional advertising.

2. Case studies provide a joint-promotion opportunity.

Your business isn't the only one that benefits from a case study. Customers participating in case studies benefit, too.

Think about it. Case studies are free advertisements for your customers, not to mention the SEO factor, too. While they're not promoting their products or services, they're still getting the word out about their business. And, the case study highlights how successful their business is — showing interested leads that they're on the up and up.

3. Case studies are easily sharable.

No matter your role on the sales team, case studies are great to have on hand. You can easily share them with leads, prospects, and clients.

Whether you embed them on your website or save them as a PDF, you can simply send a link to share your case study with others. They can share that link with their peers and colleagues, and so on.

Case studies can also be useful during a sales pitch. In sales, timing is everything. If a customer is explaining a problem that was solved and discussed in your case study, you can quickly find the document and share it with them.

4. Case studies build rapport with your customers.

While case studies are very useful, they do require some back and forth with your customers to obtain the exact feedback you're looking for.

Even though time is involved, the good news is this builds rapport with your most loyal customers. You get to know them on a personal level, and they'll become more than just your most valuable clients.

And, the better the rapport you have with them, the more likely they'll be to recommend your business, products, or services to others.

5. Case studies are less opinionated than customer reviews.

Data is the difference between a case study and a review. Customer reviews are typically based on the customer's opinion of your brand. While they might write a glowing review, it's completely subjective and there's rarely empirical evidence supporting their claim.

Case studies, on the other hand, are more data-driven. While they'll still talk about how great your brand is, they support this claim with quantitative data that's relevant to the reader. It's hard to argue with data.

An effective case study must be genuine and credible. Your case study should explain why certain customers are the right fit for your business and how your company can help meet their specific needs. That way, someone in a similar situation can use your case study as a testimonial for why they should choose your business.

Use the case study questions above to create an ideal customer case study questionnaire. By asking your customers the right questions, you can obtain valuable feedback that can be shared with potential leads and convert them into loyal customers.

✨ Case Study Analysis Definition

A case study analysis is used to examine a problem and find a solution to it. This type of analysis is typically used in business as well as in other spheres, such as education, healthcare, and social sciences. The main feature of such a study is that it’s rooted in a real-life context.

Researchers use direct observations, interviews, tests, and samples to gather data for their case studies. This information is then used to develop solutions and recommendations backed with evidence.

🔎 Structure of a Case Study Analysis

Usually, a case study analysis consists of 6 parts. Each one is dedicated to a particular aspect and serves its own purpose. Let’s take a closer look at them and see how they differ.

Introduction

An introduction describes the context of the examined topic and provides substantial background on the case study’s subject. When you write it, keep in mind the following questions:

• What is your case study about?
• What is the primary goal of your research?
• Why is it important?

Problem Statement

The next part introduces the main problem or issue the study will be focusing on. Typically, it’s concerned with a challenge faced by an individual or organization in question. The problem statement provides a clear focus for the whole research.

Now, it’s time for the most interesting part—the analysis itself. When it comes to business problems, students can use various approaches, such as:

This part presents several ways to resolve the issue in question. The solutions must be realistic and achievable. It’s also worth to mention their pros and cons and thus identify the most potent ones.

Recommendations

This part focuses on the best possible solutions to the problem identified in the previous section. It explains how to implement it in practice and how it will help eliminate the issue. It may also suggest ways to deal with other, minor problems involved in the case.

Conclusions

Now, it’s time for the final part of the analysis: your conclusions . Here is what you need to do:

• Summarize the results of your case study analysis and explain how they relate to the research’s main problem.
• Be sure to emphasize how vital your study is and how it helps to make the issue more manageable.
• Make further suggestions based on your findings.

✍️ How to Write a Case Study

Now you know what to include in your case study. But how do you write one that is truly outstanding? Just follow our step-by-step guide:

1. Pick a Case to Explore

Choosing the right topic is essential. You need to do it early on to ensure that the research subject is sufficiently explored.

For example, suppose you want to examine how COVID-19 has affected the hospitality sector. In that case, you can choose either a representative case, such as a large hotel chain, or an outlier case, such as a small Bed and Breakfast that has managed to survive the pandemic. The latter case may sound more interesting, but if there's not enough information available on it, it's best to choose the former.

2. Formulate a Problem Statement

Now, you should clearly and concisely formulate the central problem you will be focusing on. To do it, answer the 5 Ws:

• What is the problem you’re researching?
• Who is affected by it?
• Where does it occur?
• When did the problem arise?
• Why is this issue significant?

If you need help with this part of your analysis, you can always use our research problem generator .

3. Gather Evidence & Collect Data

Data gathering can be done through both primary and secondary sources of information . You can use a range of research techniques, such as observations, surveys, and interviews. It is crucial to make sure the data you’ve collected is pertinent to the case study.

4. Describe Your Findings & Analyze Them

Next, you analyze trends and themes in your data. This analysis must be supported by facts and evidence. Use various analysis methods to make your study more in-depth.

5. Provide Solutions & Recommendations

Develop several possible solutions using the information you’ve gathered. Once you’ve done it, answer the following questions:

• What are the pros and cons of these solutions?
• Which one can be the most beneficial?
• How can the entity you’re analyzing implement it in practice?

The more detailed your recommendations are, the better. If possible, try to include aspects such as timeline, resource allocation, and KPIs for monitoring.

2024 Guide: 20+ Essential Data Science Case Study Interview Questions

Case studies are often the most challenging aspect of data science interview processes. They are crafted to resemble a company’s existing or previous projects, assessing a candidate’s ability to tackle prompts, convey their insights, and navigate obstacles.

To excel in data science case study interviews, practice is crucial. It will enable you to develop strategies for approaching case studies, asking the right questions to your interviewer, and providing responses that showcase your skills while adhering to time constraints.

The best way of doing this is by using a framework for answering case studies. For example, you could use the product metrics framework and the A/B testing framework to answer most case studies that come up in data science interviews.

There are four main types of data science case studies:

• Product Case Studies - This type of case study tackles a specific product or feature offering, often tied to the interviewing company. Interviewers are generally looking for a sense of business sense geared towards product metrics.
• Data Analytics Case Study Questions - Data analytics case studies ask you to propose possible metrics in order to investigate an analytics problem. Additionally, you must write a SQL query to pull your proposed metrics, and then perform analysis using the data you queried, just as you would do in the role.
• Modeling and Machine Learning Case Studies - Modeling case studies are more varied and focus on assessing your intuition for building models around business problems.
• Business Case Questions - Similar to product questions, business cases tackle issues or opportunities specific to the organization that is interviewing you. Often, candidates must assess the best option for a certain business plan being proposed, and formulate a process for solving the specific problem.

How Case Study Interviews Are Conducted

Oftentimes as an interviewee, you want to know the setting and format in which to expect the above questions to be asked. Unfortunately, this is company-specific: Some prefer real-time settings, where candidates actively work through a prompt after receiving it, while others offer some period of days (say, a week) before settling in for a presentation of your findings.

It is therefore important to have a system for answering these questions that will accommodate all possible formats, such that you are prepared for any set of circumstances (we provide such a framework below).

Why Are Case Study Questions Asked?

Case studies assess your thought process in answering data science questions. Specifically, interviewers want to see that you have the ability to think on your feet, and to work through real-world problems that likely do not have a right or wrong answer. Real-world case studies that are affecting businesses are not binary; there is no black-and-white, yes-or-no answer. This is why it is important that you can demonstrate decisiveness in your investigations, as well as show your capacity to consider impacts and topics from a variety of angles. Once you are in the role, you will be dealing directly with the ambiguity at the heart of decision-making.

Perhaps most importantly, case interviews assess your ability to effectively communicate your conclusions. On the job, data scientists exchange information across teams and divisions, so a significant part of the interviewer’s focus will be on how you process and explain your answer.

Quick tip: Because case questions in data science interviews tend to be product- and company-focused, it is extremely beneficial to research current projects and developments across different divisions , as these initiatives might end up as the case study topic.

How to Answer Data Science Case Study Questions (The Framework)

There are four main steps to tackling case questions in Data Science interviews, regardless of the type: clarify, make assumptions, gather context, and provide data points and analysis.

Step 1: Clarify

Clarifying is used to gather more information . More often than not, these case studies are designed to be confusing and vague. There will be unorganized data intentionally supplemented with extraneous or omitted information, so it is the candidate’s responsibility to dig deeper, filter out bad information, and fill gaps. Interviewers will be observing how an applicant asks questions and reach their solution.

For example, with a product question, you might take into consideration:

• What is the product?
• How does the product work?
• How does the product align with the business itself?

Step 2: Make Assumptions

When you have made sure that you have evaluated and understand the dataset, start investigating and discarding possible hypotheses. Developing insights on the product at this stage complements your ability to glean information from the dataset, and the exploration of your ideas is paramount to forming a successful hypothesis. You should be communicating your hypotheses with the interviewer, such that they can provide clarifying remarks on how the business views the product, and to help you discard unworkable lines of inquiry. If we continue to think about a product question, some important questions to evaluate and draw conclusions from include:

• Who uses the product? Why?
• What are the goals of the product?
• How does the product interact with other services or goods the company offers?

The goal of this is to reduce the scope of the problem at hand, and ask the interviewer questions upfront that allow you to tackle the meat of the problem instead of focusing on less consequential edge cases.

Step 3: Propose a Solution

Now that a hypothesis is formed that has incorporated the dataset and an understanding of the business-related context, it is time to apply that knowledge in forming a solution. Remember, the hypothesis is simply a refined version of the problem that uses the data on hand as its basis to being solved. The solution you create can target this narrow problem, and you can have full faith that it is addressing the core of the case study question.

Keep in mind that there isn’t a single expected solution, and as such, there is a certain freedom here to determine the exact path for investigation.

Step 4: Provide Data Points and Analysis

Finally, providing data points and analysis in support of your solution involves choosing and prioritizing a main metric. As with all prior factors, this step must be tied back to the hypothesis and the main goal of the problem. From that foundation, it is important to trace through and analyze different examples– from the main metric–in order to validate the hypothesis.

Quick tip: Every case question tends to have multiple solutions. Therefore, you should absolutely consider and communicate any potential trade-offs of your chosen method. Be sure you are communicating the pros and cons of your approach.

Note: In some special cases, solutions will also be assessed on the ability to convey information in layman’s terms. Regardless of the structure, applicants should always be prepared to solve through the framework outlined above in order to answer the prompt.

The Role of Effective Communication

There have been multiple articles and discussions conducted by interviewers behind the Data Science Case Study portion, and they all boil down success in case studies to one main factor: effective communication.

All the analysis in the world will not help if interviewees cannot verbally work through and highlight their thought process within the case study. Again, interviewers are keyed at this stage of the hiring process to look for well-developed “soft-skills” and problem-solving capabilities. Demonstrating those traits is key to succeeding in this round.

To this end, the best advice possible would be to practice actively going through example case studies, such as those available in the Interview Query questions bank . Exploring different topics with a friend in an interview-like setting with cold recall (no Googling in between!) will be uncomfortable and awkward, but it will also help reveal weaknesses in fleshing out the investigation.

Don’t worry if the first few times are terrible! Developing a rhythm will help with gaining self-confidence as you become better at assessing and learning through these sessions.

Product Case Study Questions

With product data science case questions , the interviewer wants to get an idea of your product sense intuition. Specifically, these questions assess your ability to identify which metrics should be proposed in order to understand a product.

1. How would you measure the success of private stories on Instagram, where only certain close friends can see the story?

Start by answering: What is the goal of the private story feature on Instagram? You can’t evaluate “success” without knowing what the initial objective of the product was, to begin with.

One specific goal of this feature would be to drive engagement. A private story could potentially increase interactions between users, and grow awareness of the feature.

Now, what types of metrics might you propose to assess user engagement? For a high-level overview, we could look at:

• Average stories per user per day
• Average Close Friends stories per user per day

However, we would also want to further bucket our users to see the effect that Close Friends stories have on user engagement. By bucketing users by age, date joined, or another metric, we could see how engagement is affected within certain populations, giving us insight on success that could be lost if looking at the overall population.

2. How would you measure the success of acquiring new users through a 30-day free trial at Netflix?

More context: Netflix is offering a promotion where users can enroll in a 30-day free trial. After 30 days, customers will automatically be charged based on their selected package. How would you measure acquisition success, and what metrics would you propose to measure the success of the free trial?

One way we can frame the concept specifically to this problem is to think about controllable inputs, external drivers, and then the observable output . Start with the major goals of Netflix:

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

Looking at acquisition output metrics specifically, there are several top-level stats that we can look at, including:

• Conversion rate percentage
• Cost per free trial acquisition
• Daily conversion rate

With these conversion metrics, we would also want to bucket users by cohort. This would help us see the percentage of free users who were acquired, as well as retention by cohort.

3. How would you measure the success of Facebook Groups?

Start by considering the key function of Facebook Groups . You could say that Groups are a way for users to connect with other users through a shared interest or real-life relationship. Therefore, the user’s goal is to experience a sense of community, which will also drive our business goal of increasing user engagement.

What general engagement metrics can we associate with this value? An objective metric like Groups monthly active users would help us see if Facebook Groups user base is increasing or decreasing. Plus, we could monitor metrics like posting, commenting, and sharing rates.

There are other products that Groups impact, however, specifically the Newsfeed. We need to consider Newsfeed quality and examine if updates from Groups clog up the content pipeline and if users prioritize those updates over other Newsfeed items. This evaluation will give us a better sense of if Groups actually contribute to higher engagement levels.

4. How would you analyze the effectiveness of a new LinkedIn chat feature that shows a “green dot” for active users?

Note: Given engineering constraints, the new feature is impossible to A/B test before release. When you approach case study questions, remember always to clarify any vague terms. In this case, “effectiveness” is very vague. To help you define that term, you would want first to consider what the goal is of adding a green dot to LinkedIn chat.

5. How would you diagnose why weekly active users are up 5%, but email notification open rates are down 2%?

What assumptions can you make about the relationship between weekly active users and email open rates? With a case question like this, you would want to first answer that line of inquiry before proceeding.

Hint: Open rate can decrease when its numerator decreases (fewer people open emails) or its denominator increases (more emails are sent overall). Taking these two factors into account, what are some hypotheses we can make about our decrease in the open rate compared to our increase in weekly active users?

Data Analytics Case Study Questions

Data analytics case studies ask you to dive into analytics problems. Typically these questions ask you to examine metrics trade-offs or investigate changes in metrics. In addition to proposing metrics, you also have to write SQL queries to generate the metrics, which is why they are sometimes referred to as SQL case study questions .

6. Using the provided data, generate some specific recommendations on how DoorDash can improve.

In this DoorDash analytics case study take-home question you are provided with the following dataset:

• Customer order time
• Restaurant order time
• Driver arrives at restaurant time
• Order delivered time
• Customer ID
• Amount of discount
• Amount of tip

With a dataset like this, there are numerous recommendations you can make. A good place to start is by thinking about the DoorDash marketplace, which includes drivers, riders and merchants. How could you analyze the data to increase revenue, driver/user retention and engagement in that marketplace?

7. After implementing a notification change, the total number of unsubscribes increases. Write a SQL query to show how unsubscribes are affecting login rates over time.

This is a Twitter data science interview question , and let’s say you implemented this new feature using an A/B test. You are provided with two tables: events (which includes login, nologin and unsubscribe ) and variants (which includes control or variant ).

We are tasked with comparing multiple different variables at play here. There is the new notification system, along with its effect of creating more unsubscribes. We can also see how login rates compare for unsubscribes for each bucket of the A/B test.

Given that we want to measure two different changes, we know we have to use GROUP BY for the two variables: date and bucket variant. What comes next?

8. Write a query to disprove the hypothesis: Data scientists who switch jobs more often end up getting promoted faster.

More context: You are provided with a table of user experiences representing each person’s past work experiences and timelines.

This question requires a bit of creative problem-solving to understand how we can prove or disprove the hypothesis. The hypothesis is that a data scientist that ends up switching jobs more often gets promoted faster.

Therefore, in analyzing this dataset, we can prove this hypothesis by separating the data scientists into specific segments on how often they jump in their careers.

For example, if we looked at the number of job switches for data scientists that have been in their field for five years, we could prove the hypothesis that the number of data science managers increased as the number of career jumps also rose.

• Never switched jobs: 10% are managers
• Switched jobs once: 20% are managers
• Switched jobs twice: 30% are managers
• Switched jobs three times: 40% are managers

9. Write a SQL query to investigate the hypothesis: Click-through rate is dependent on search result rating.

More context: You are given a table with search results on Facebook, which includes query (search term), position (the search position), and rating (human rating from 1 to 5). Each row represents a single search and includes a column has_clicked that represents whether a user clicked or not.

This question requires us to formulaically do two things: create a metric that can analyze a problem that we face and then actually compute that metric.

Think about the data we want to display to prove or disprove the hypothesis. Our output metric is CTR (clickthrough rate). If CTR is high when search result ratings are high and CTR is low when the search result ratings are low, then our hypothesis is proven. However, if the opposite is true, CTR is low when the search result ratings are high, or there is no proven correlation between the two, then our hypothesis is not proven.

With that structure in mind, we can then look at the results split into different search rating buckets. If we measure the CTR for queries that all have results rated at 1 and then measure CTR for queries that have results rated at lower than 2, etc., we can measure to see if the increase in rating is correlated with an increase in CTR.

10. How would you help a supermarket chain determine which product categories should be prioritized in their inventory restructuring efforts?

You’re working as a Data Scientist in a local grocery chain’s data science team. The business team has decided to allocate store floor space by product category (e.g., electronics, sports and travel, food and beverages). Help the team understand which product categories to prioritize as well as answering questions such as how customer demographics affect sales, and how each city’s sales per product category differs.

Modeling and Machine Learning Case Questions

Machine learning case questions assess your ability to build models to solve business problems. These questions can range from applying machine learning to solve a specific case scenario to assessing the validity of a hypothetical existing model . The modeling case study requires a candidate to evaluate and explain any certain part of the model building process.

11. Describe how you would build a model to predict Uber ETAs after a rider requests a ride.

Common machine learning case study problems like this are designed to explain how you would build a model. Many times this can be scoped down to specific parts of the model building process. Examining the example above, we could break it up into:

How would you evaluate the predictions of an Uber ETA model?

What features would you use to predict the Uber ETA for ride requests?

Our recommended framework breaks down a modeling and machine learning case study to individual steps in order to tackle each one thoroughly. In each full modeling case study, you will want to go over:

• Data processing
• Feature Selection
• Model Selection
• Cross Validation
• Evaluation Metrics
• Testing and Roll Out

12. How would you build a model that sends bank customers a text message when fraudulent transactions are detected?

Additionally, the customer can approve or deny the transaction via text response.

Let’s start out by understanding what kind of model would need to be built. We know that since we are working with fraud, there has to be a case where either a fraudulent transaction is or is not present .

Hint: This problem is a binary classification problem. Given the problem scenario, what considerations do we have to think about when first building this model? What would the bank fraud data look like?

13. How would you design the inputs and outputs for a model that detects potential bombs at a border crossing?

Additional questions. How would you test the model and measure its accuracy? Remember the equation for precision:

Because we can not have high TrueNegatives, recall should be high when assessing the model.

14. Which model would you choose to predict Airbnb booking prices: Linear regression or random forest regression?

Start by answering this question: What are the main differences between linear regression and random forest?

Random forest regression is based on the ensemble machine learning technique of bagging . The two key concepts of random forests are:

• Random sampling of training observations when building trees.
• Random subsets of features for splitting nodes.

Random forest regressions also discretize continuous variables, since they are based on decision trees and can split categorical and continuous variables.

Linear regression, on the other hand, is the standard regression technique in which relationships are modeled using a linear predictor function, the most common example represented as y = Ax + B.

Let’s see how each model is applicable to Airbnb’s bookings. One thing we need to do in the interview is to understand more context around the problem of predicting bookings. To do so, we need to understand which features are present in our dataset.

We can assume the dataset will have features like:

• Location features.
• Seasonality.
• Number of bedrooms and bathrooms.
• Private room, shared, entire home, etc.
• External demand (conferences, festivals, sporting events).

Which model would be the best fit for this feature set?

15. Using a binary classification model that pre-approves candidates for a loan, how would you give each rejected application a rejection reason?

More context: You do not have access to the feature weights. Start by thinking about the problem like this: How would the problem change if we had ten, one thousand, or ten thousand applicants that had gone through the loan qualification program?

Pretend that we have three people: Alice, Bob, and Candace that have all applied for a loan. Simplifying the financial lending loan model, let us assume the only features are the total number of credit cards , the dollar amount of current debt , and credit age . Here is a scenario:

Alice: 10 credit cards, 5 years of credit age, $\$20K$ in debt

Bob: 10 credit cards, 5 years of credit age, $\$15K$ in debt

Candace: 10 credit cards, 5 years of credit age, $\$10K$ in debt

If Candace is approved, we can logically point to the fact that Candace’s $\$10K$ in debt swung the model to approve her for a loan. How did we reason this out?

If the sample size analyzed was instead thousands of people who had the same number of credit cards and credit age with varying levels of debt, we could figure out the model’s average loan acceptance rate for each numerical amount of current debt. Then we could plot these on a graph to model the y-value (average loan acceptance) versus the x-value (dollar amount of current debt). These graphs are called partial dependence plots.

Business Case Questions

In data science interviews, business case study questions task you with addressing problems as they relate to the business. You might be asked about topics like estimation and calculation, as well as applying problem-solving to a larger case. One tip: Be sure to read up on the company’s products and ventures before your interview to expose yourself to possible topics.

16. How would you estimate the average lifetime value of customers at a business that has existed for just over one year?

More context: You know that the product costs $\$100$ per month, averages 10% in monthly churn, and the average customer stays for 3.5 months.

Remember that lifetime value is defined by the prediction of the net revenue attributed to the entire future relationship with all customers averaged. Therefore, $\$100$ * 3.5 = $\$350$… But is it that simple?

Because this company is so new, our average customer length (3.5 months) is biased from the short possible length of time that anyone could have been a customer (one year maximum). How would you then model out LTV knowing the churn rate and product cost?

17. How would you go about removing duplicate product names (e.g. iPhone X vs. Apple iPhone 10) in a massive database?

See the full solution for this Amazon business case question on YouTube:

18. What metrics would you monitor to know if a 50% discount promotion is a good idea for a ride-sharing company?

This question has no correct answer and is rather designed to test your reasoning and communication skills related to product/business cases. First, start by stating your assumptions. What are the goals of this promotion? It is likely that the goal of the discount is to grow revenue and increase retention. A few other assumptions you might make include:

• The promotion will be applied uniformly across all users.
• The 50% discount can only be used for a single ride.

How would we be able to evaluate this pricing strategy? An A/B test between the control group (no discount) and test group (discount) would allow us to evaluate Long-term revenue vs average cost of the promotion. Using these two metrics how could we measure if the promotion is a good idea?

19. A bank wants to create a new partner card, e.g. Whole Foods Chase credit card). How would you determine what the next partner card should be?

More context: Say you have access to all customer spending data. With this question, there are several approaches you can take. As your first step, think about the business reason for credit card partnerships: they help increase acquisition and customer retention.

One of the simplest solutions would be to sum all transactions grouped by merchants. This would identify the merchants who see the highest spending amounts. However, the one issue might be that some merchants have a high-spend value but low volume. How could we counteract this potential pitfall? Is the volume of transactions even an important factor in our credit card business? The more questions you ask, the more may spring to mind.

20. How would you assess the value of keeping a TV show on a streaming platform like Netflix?

Say that Netflix is working on a deal to renew the streaming rights for a show like The Office , which has been on Netflix for one year. Your job is to value the benefit of keeping the show on Netflix.

Start by trying to understand the reasons why Netflix would want to renew the show. Netflix mainly has three goals for what their content should help achieve:

• Acquisition: To increase the number of subscribers.
• Retention: To increase the retention of active subscribers and keep them on as paying members.
• Revenue: To increase overall revenue.

One solution to value the benefit would be to estimate a lower and upper bound to understand the percentage of users that would be affected by The Office being removed. You could then run these percentages against your known acquisition and retention rates.

21. How would you determine which products are to be put on sale?

Let’s say you work at Amazon. It’s nearing Black Friday, and you are tasked with determining which products should be put on sale. You have access to historical pricing and purchasing data from items that have been on sale before. How would you determine what products should go on sale to best maximize profit during Black Friday?

To start with this question, aggregate data from previous years for products that have been on sale during Black Friday or similar events. You can then compare elements such as historical sales volume, inventory levels, and profit margins.

9 Types of Questions in Actual Case Interviews

Case interviews at management consulting firms are among the most difficult job interviews, but they are also quite predictable. Once you know the types of questions they ask, preparation is straightforward.

Using years of experience at McKinsey, as well as field reports from thousands of candidates, I’ve crafted a list of 8 common case interview questions, and in this article, I’ll show you how to answer each of them.

Case interview questions – Overview

Types of case interview questions .

Most questions in case interviews belong to one of these 9 types:

1. Framework/issue tree questions 2. Market-sizing and guesstimate questions 3. Valuation questions 4. Brain teaser questions 5. Chart insight questions 6. Value proposition questions 7. Information questions 8. Math problems 9. Solution-finding questions

In this article, we’ll discuss how to answer each question, along with the necessary tips and tricks.

How to answer case interview questions

There are the fo ur basic steps to answer case interview questions:

• Step 1: Clarify any unclear points in the question
• Step 2: Announce approach and ask for time
• Step 3: Draw issue trees to solve the given problem
• Step 4: Pitch your answer and end with a takeaway conclusion.

This general outline may vary depending on each type and each question – for example, brain teasers or information questions need only the last step, while market-sizing and framework questions need all four steps to deliver the perfect answer.

Type 1 – Framework/Issue tree questions

These are on top of the list among popular case interview questions!

If the interviewer asks you to identify factors contributing to a problem or to break down an entity (such as the revenue of a business), he/she is telling you to draw an issue tree.

And to draw a spot-on issue tree, you need to master consulting problem-solving foundations , the MECE principle , and common consulting frameworks . You should check out our other articles on these topics before moving on, because mastering the issue tree is the key to acing every possible case interview.

You also need good business intuition to draw good issue trees, so that’s all the more reason to start reading every day.

Gastronomia – a gourmet restaurant chain has found the turnover rate among its highly-skilled chefs increasing dramatically for the last 3 years; this has led to a noticeable decline in food quality and increased training costs, among other negative effects.

Which factors would you consider when tackling this turnover problem?

Job: Factors from the job itself. Further divided into 3 sub-branches

• Compensations: are the salaries, bonuses, and benefits attractive enough?
• Difficulty: is the job too difficult?
• Nature: is the job too boring, too unengaging, too repetitive…?

Company: Factors from the work environment within the restaurant chain, surrounding the affected jobs. Further divided into 2 sub-branches

• Cultural environment: is the culture at Gastronomia compatible with the chefs?
• Physical environment: is the physical working environment at Gastronomia safe, comfortable, convenient…?

Competitors: Factors from outside the restaurant chain, related to competing job offers. Further divided into 2 sub-branches.

• Inside industry: are other restaurant chains competing with Gastronomia for skilled personnel?
• Outside industry: are there new career options or changes in existing alternatives that draw chefs away from restaurant chains like Gastronomia?

For detailed guides on issue trees, frameworks and their principles, see the articles on Issue Trees , Case Interview Frameworks, and MECE Principle

Type 2 – Market-sizing & guesstimate

These questions go along the lines of “How many trees are there in Central Park?” or “What’s the market size of pick-up trucks in the USA?”

The key to nailing market-sizing and guesstimate questions lies in not the closest results, but the most logical and structured approaches. In fact, the interviewer expects you to follow these four steps:

Step 1: Clarify: Make sure you and the interviewer are on the same page regarding every detail and terminology, so you won’t be answering the wrong question.

Step 2: Break down the problem: Break the item in the question (number of trees in Central Park, market size of pickup trucks) down into smaller, easy-to-estimate pieces.

Step 3: Solve each piece: Estimate each small piece one at a time; each estimation should be backed by facts, figures, or at least observations.

Step 4: Consolidate the pieces: Combine the previous estimations to arrive at a final result; be quick with the math, but don’t rush it if you aren’t confident.

Unless you come up with something about 10 times the reasonable estimate, don’t worry about being “wrong” – the interviewer is unlikely to have a “correct” number in mind, he/she just wants to see your structured mindset.

This question type is so common, we devote a whole article to it, and our Case Interview End-to-End Secrets Program have a separate package on these questions. Check out our comprehensive guide on Market-Sizing & Guesstimate Questions for more details!

Now, here’s a quick example for you to try and get used to this type:

How many smartphones are sold each year, globally?

• Smartphones are phones using exclusively touch-screens.
• “Sold” means sold to the end-consumers. 
• The market size is calculated at present.

Break down the problem:

The global smartphone market can be divided into three segments – developed countries, developing countries, and undeveloped countries.

In each segment, the annual unit sales of smartphones depend on four variables:

• The percentage of “phone-owning age” people among the population
• The percentage of smartphone owners within the “phone-owning age” group.
• The average, annual, per capita “consumption” of smartphones for those owners.

Solve each piece:

• The population is 1.5 billion in developed countries, 5.5 billion in developing countries, and 1 billion in undeveloped countries.
• 80% of the world population is in the “phone-owning age” (Global life expectancy is 70 and everyone older than 15 years counts towards the “phone-owning age” group)
• 100% of the phone-owning age in developed countries will own a smartphone; the figure in developing countries is 75%, while in undeveloped countries it’s 10%.
• The average smartphone user replaces their phone every 3 years – so they “consume” 0.33 phones each year.

=> Estimated global smartphone market: 1.53 billion units per year

=> Actual 2019 global smartphone sales:  1.37 billion units (error margin: 11.7%).

This market-sizing question is solved using a four-step process, which is explained in this article:  Market-Sizing & Guesstimate Questions

Type 3 – Valuation questions

Valuation questions are about estimating the monetary value of a business, and these are very popular in case interviews too!

Valuation questions are a blend of guesstimation/market-sizing, math, and business. They also require basic finance knowledge. There are three ways to estimate the value of a business:

• The NPV Method: take the net cash flow generated by the business, and discount it to the present to account for time value of money. Basically “this company is worth X dollars because it gives me Y dollars over Z years”. This approach works best when the cash flow from the business is positive and stable.
• The Market Method: take one index of the firm (which can be stocks or anything depending on the industry) and multiply it with an industry multiple (the value of one unit of the said index). In other words, “this company is worth AxB dollars because it has A traffic and each traffic is worth B dollars”. This approach works best when the market is transparent and data on similar firms are accessible – usually with major, established industries such as commercial airlines.

In real case interviews, you have to justify your approach then ask the interviewer to give you the necessary data.

Our client wants to sell his organic-food restaurant (called “Cato’s Cabbage Farm”) to retire. How much is his restaurant worth?

(Supposed the interviewer gives you the following data: his current income from the restaurant is $100,000 per year; two other restaurants in the neighborhood – one with 2 times more customers, and another about 0.75 times, have been sold at $1,800,000 and $1,000,000 respectively).

NPV Method: Cato’s Cabbage Farm value = $100,000 / 10% = $1,000,000

Market Method:

Assume the number of customers for Cato’s Cabbage Farm is 1 “customer unit”, then the two neighborhood restaurants get 2 and 0.75 “customer units”.

• Industry multiple: ($1,800,000+$1,000,000) / (2+0.75) = ~$1,018,182
• Cato’s Cabbage Farm value = $1,018,182 x 1 = $1,018,182

Type 4 – Brain teasers

Brain teasers are the least predictable case interview questions – but even these can be learned!

Brain teasers are riddles designed to test unconventional, creative, and logical thinking. A famous example of this is Accenture’s “How do you put a giraffe in a fridge?”.

Although not as popular as before, brain teasers might still appear in consulting interviews; therefore, you should spend some time to prepare.

Most brain teasers can be allocated into these seven types:

• Logical questions are pure logic riddles – there’s no trick, no illusion, no creativity.

In our Case Interview End-to-End Secrets Program , there are +200 brain teasers to help you prepare for these “unpredictable” questions. You can also read our article about Case Interview Brain Teasers for insights on all of these exciting brain teasers, as well as 30 example questions and answers!

How do you put a giraffe in a fridge?

Open the fridge, put the giraffe in, then close the fridge. The question never says how big the fridge or the giraffe is.

For the logic and approach behind each kind of brain teasers, see the article on Brain Teasers.

Type 5 – Chart insight questions

You can’t be a management consultant without mastering the use of charts – the complex, scary-looking real-world charts such as those included in our Case Interview End-to-End Secrets Program.

In management consulting and case interviews, most charts are one (or a combination) of these four basic types:

• Bar charts compare the values of several items at one point in time, or 1-2 items at several time intervals.
• Line charts illustrate time-series data, i.e trends in data over a continuous period.
• Pie charts illustrate proportions, i.e “parts of a whole” analyses.
• Scatter-plots use data points to visualize how two variables relate to each other.

To read these charts and answer chart-insights questions effectively, you must follow a structured, comprehensive process:

You can find a more detailed guide in the Charts section in our article about Consulting Math.

What can you draw from the following chart?

Trends in chart:

• Steady rise in the number of confirmed deaths to about 70-80 per million;
• Both changes started around March 10-11.
• These sudden rises can be explained by events occurring in early-March, and 2.
• If number of cases is kept low, the threat from COVID-19 will remain minimal, considering a mortality rate of only 2%.

Type 6 – Value proposition questions

No business or consulting candidate can succeed without understanding the customers!

Value-proposition questions are not only about correctly identifying customer preferences, but also about analyzing and delivering the answer in a structured fashion. The former relies heavily on business knowledge and intuition, but the latter can be trained methodically and quickly. Personally, I use a “double issue-tree” – essentially a table with customer segments on one axis and proposed values on the other:

For segmenting customers, you can use the following table. However, don’t over-rely on it, since there may be more relevant and insightful question-specific segmentations.

In some cases, clarification is also necessary – both to avoid “answering the wrong question” and to narrow down the range of customers/values you need to cover in the answer.

What will a customer consider when buying a Toyota sedan?

Clarification: A sedan must be branded “Toyota” to be a Toyota sedan – cars with other Toyota-owned brands such as Lexus or Ranz do not count in this question.

Situational Assessment:

Toyota sedans occupy the entry-level and mid-range price segments, so Toyota customers will be more price-conscious than, for example, Lexus customers.

They are also less likely to lean considerably towards one particular factor, so achieving a balance is extremely important.

Functionality factors:

• Comfort: Toyota sedans are mostly for everyday use, so customers should feel comfortable being inside the car.
• Utility: Toyota sedans are used for multiple purposes, so convenience for a wide range of uses is important.

Cost factors

• Purchase price: A car can be an expensive investment while Toyota’s low-to-mid-range customers are more price-conscious, so having a cheap/reasonable price is important.
• Fuel and maintenance: Maintenance and fuel costs over time are likewise inversely related to the decision to buy a Toyota sedan.

Physical factors

• Performance: Customers are usually drivers themselves, who often pay attention to the technical characteristics of the car (speed, acceleration, handling, etc.)
• Visual design: The car should possess the same level of visual appeal as other competitors in the same segment.
• Build quality: Parts of the car should be assembled in a reasonably good manner.

Emotional factors

• Branding: The car should come from a well-known, reputable brand
• Personal preferences: Some customers choose specific cars simply because they “like” the car.

Type 7 – Information questions

In any problem-solving process, information is one of the overarching concerns!

“Information questions” essentially ask if the piece of data you use is obtainable in the first place. In real consulting work, data is not always available – client team members may refuse to cooperate or there’s simply no data on the subject.

There are many kinds of information sources in case interviews/consulting works, but I’ll divide them into primary and secondary sources. Primary sources means you must do the research yourself (or pay someone else to do it for you), such as customer surveys or mystery shoppings. If someone already did that research, and you use their results, it’s called a secondary source – you can get these from the client , the consulting firm you work for, or third-parties such as market research firms or external industry experts.

You can find out more about these sources and how to cite them in real case interviews through this free Prospective Candidate Starter Pack, which contains a glossary of data sources in consulting.

Our Prospective Candidate Starter Pack has a sheet containing all the possible sources of information in case interviews and consulting projects, among numerous other free resources; you can download and use it to answer these questions, by subscribing to our newsletter at the end of this article.

How do you assess your target customer’s preferences for sports cars?

Primary sources: customer survey, customer interviews, Secondary sources: industry reports, client sales reports, third-party expert interview, client expert interview

Type 8 – Math problems

A lot of information in case interviews and consulting work comes in the quantitative form, so you won’t escape Math by joining the consulting industry!

When you have to do the math, perform back-of-the-envelope calculations in a structured fashion, and say out loud what you’re writing. For one thing, it’s safe; for another, you show that you’re careful, organized, and reliable – just like actual consultants.

We have a Math Practice Tool right here! Use it every day, and you’ll be a master of mental calculations in no time flat!

We have a dedicated article on Consulting Math, which you should definitely read.

Type 9 – Solution-finding questions

What’s the point of analyzing a problem, if not to solve it?!

When dealing with solution questions, keep these four points in mind:

• Firstly, in case interviews as well as real consulting projects, solutions must always solve every root cause of a problem, so remember to check if your solutions are relevant and comprehensive.
• Secondly, every solution must be actionable – if your solutions are too expensive, too time-consuming, etc. for the client, they’re useless.
• Thirdly, the interview expects a highly-structured answer; so segment your solutions based on their characteristics (long-term vs short-term is the easiest segmentation)

Last but not least, deliver at least two solutions, preferably three to five. Otherwise, you’ll appear uncreative and lazy to the interviewer’s eyes.

Nailing these questions relies on having excellent business intuition; our Case Interview End-to-End Program has a dedicated Business Intuition package, but you should also train a habit of reading consulting and business articles daily, to sharpen your business mind.

A restaurant that relies solely on on-premise dining found the loss of adjacent parking space (due to termination of contract) harming their revenue. How can they fix that?

The solutions for the restaurant’s parking space problem can be divided into two types:

• Short-term solutions: Find new parking space around the neighborhood, or renegotiate for old parking space (possibly at a higher price).
• Long-term solutions: Introduce takeaway items and off-premise dining.

Reminders on case interview questions

The questions are not clear-cut in candidate-led cases.

There are two extremes in consulting case interview format: interviewer-led (McKinsey) and candidate-led (BCG, Bain).

Interviewer-led cases, on one hand, consist of multiple, clear-cut questions in a larger business case context; the candidate navigates through these questions to arrive at the solutions.

Candidate-led cases, on the other hand, have one big problem, which the candidate must break down into small pieces to identify the root causes and deliver solutions.

This list, therefore, is much more relevant to the interviewer-led format; nonetheless, this guide is still quite beneficial for candidate-led cases, because when solving that big problem, you’ll have to tackle small issues similar to the 8 aforementioned question types.

Mastering the fundamentals is crucial to consistent performance

Although it’s good to study the case interview questions, it is no substitute for mastering the fundamental principles.

Learning the exercises without the basics is like building a house without a foundation. My poor neighbor’s house developed a huge crack right down the center because of its weak foundation, so make sure to build your case interview prep a strong one by knowing the basics first.

Once you’ve mastered the fundamentals, you’ll become much more flexible – this quality is getting increasingly important because case interviews are getting less predictable, and more realistic.

If you haven’t, I advise you to read these articles (especially the first 4) before practicing the question types:

• Case Interview 101
• Issue Tree – The Complete Guide
• MECE Principle
• Case Interview Frameworks
• McKinsey Case Interview – Interviewer-led Format
• BCG & Bain Case Interview – Candidate-led Format

Expect the unexpected

If you study those nine question types, rest assured that you’ve covered the majority of questions in case interviews.

However, these are not all the possible questions you might be given. In actual cases, there are always questions that cannot be categorized neatly. If you do not prepare for these questions, it’s easy to be thrown off-balance.

So, how do you prepare for “the unexpected”?

• Master the basics: Focus your efforts on the basics, once you’ve mastered them it’d be comfortable to move on to higher, more sophisticated levels.
• Business Intuition : You need business intuition for a business-related job, it’s simple as that. Nearly every case concerns business in one way or another – even public sector cases. This is why we also teach business intuition in our Case Interview E2E Secret Program.
• Have mock case interviews : Practice case interviews with ex-consultants will help you get a sense of what might happen or how you might be evaluated in actual cases. Highly experienced coaches from MConsultingPrep will review your performance, giving you the most valuable feedback and actionable tips & techniques.

Answering essay questions in exams

Writing an essay in an exam is similar in many ways to writing an essay for an assignment: It needs to be clearly structured, and your ideas need to be linked and supported by evidence.

Essay questions in exams

• Read the question through carefully to make sure you are answering what has been asked.  Missing one part of a question can cost you a lot of marks.
• Make a quick plan of the points you want to include in your answer.
• Use essay structure: introduction, points, conclusion.  But if you run out of time, it can be a good idea to write notes.
• Get right to the point from the beginning.  Use the words from the question to write your first sentence. For example:

Question: What do you think is the most important intercultural communication issue in New Zealand? First sentence: At present in New Zealand the most important intercultural communication issue is...

• Remember to include one idea per paragraph, and to begin each paragraph with a clear topic sentence.
• Make sure your writing is legible.
• Grammar, punctuation and spelling are not as important as in an assignment but should still be of a good standard.

Answering case study questions

Exam questions that ask you to anlayse case studies (also called scenarios) are usually designed to test your ability to relate theories and concepts to real-world situations.

Preparing for case studies before the exam:

• Start by identifying the theories and concepts covered in your course.  Organise and review the information you have on these theories/concepts so you understand them.
• Practice reading case studies and identifying relevant information. It's probably useful to practice doing this with a time limit as you will have one in your exam.
• Practice relating concepts and theories to real-world situations: ask lecturers and check textbooks for practice examples. It is also worth checking past exams for your course to see if there are examples of case study questions.

During the exam

• Take time to plan: Have a clear idea of how much time you have to answer the question. Then plan to spend some time reading the exam question, the case study and planning your answer. Take time to make sure you have understood the case study and know what the exam question is asking you to do:
• Read the exam question(s)
• Then skim read the case study to get the general idea. Highlight or underline key points
• Reread the question to make sure you understand it and to focus your attention when you reread the case study.
• Reread the case study carefully. Make a note of any ideas that you think of.
• Answer the question linking relevant theories and concepts to specific information from the case study. Usually you will need to write your answers in clearly formed paragraphs which have a clear topic that is well-supported with evidence and examples.
• Instead of simply describing or restating information from the case itself, use specific details or examples to support the points you are trying to make. This is where you link theory to the facts from the case study.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

Need of MBA Case Studies

Case i: chemco case.

• ChemCo is a quality leader in the U.K. car batteries market.
• Customer battery purchases in the automobile market are highly seasonal.
• The fork-lift business was added to utilize idle capacity during periods of inactivity.
• This is a low-growth industry (1% annual growth over the last two years)
• Large customers are sophisticated and buy based on price and quality. Smaller customers buy solely on price.
• There is a Spanish competitor in the market who offers low priced batteries of inferior quality.

• GD: Content
• Solved Case Studies
• High quality product, but low end customers care more about price than quality
• Mismanaged product diversification in a price sensitive market
• Alternative 1: Establish an Off-Brand for the fork-lift business
• Alternative 2: Educate the customer market about product quality
• Alternative 3: Exit the fork-lift battery business
• Establishing the firm's quality image
• Increase in market share
• Increase in sales
• Cost of the product
• Protect firm's quality image in the automobile industry
• Redesigned product to reduce the cost of manufacture
• Low price to enable it to compete with Spanish producer
• Make use of the quality leadership in car batteries market
• Offer reliability testing, extended warranties etc. to promote quality image
• Set higher prices to extract surplus from these advantages
• A passive strategy, not proactive
• Recommendations: Alternative 1 is recommended in this case. Since the firm operates in an industry which has low growth, hence it can expand market share and sales only by taking the customers from other players. Hence, it needs to tackle the Spanish competitor head-on by aggressively pricing its product. At the same time, launching a low-priced product under the same brand name erodes the high quality image in the car batteries market. Hence, the best option is to go for an off-brand to target the fork-lift customers who are increasingly becoming price sensitive. This will enable the company to ward off the threat in short-term and build its position strongly in the long-term.

Case II: NAKAMURA LACQUER COMPANY

• The Nakamura Lacquer Company: The Nakamura Lacquer Company based in Kyoto, Japan was one of the many small handicraft shops making lacquerware for the daily table use of the Japanese people.
• Mr. Nakamura- the personality: In 1948, a young Mr. Nakamura took over his family business. He saw an opportunity to cater to a new market of America, i.e. GI's of the Occupation Army who had begun to buy lacquer ware as souvenirs. However, he realized that the traditional handicraft methods were inadequate. He was an innovator and introduced simple methods of processing and inspection using machines. Four years later, when the Occupation Army left in 1952, Nakamura employed several thousand men, and produced 500,000 pieces of lacquers tableware each year for the Japanese mass consumer market. The profit from operations was $250,000.
• The Brand: Nakamura named his brand “Chrysanthemum” after the national flower of Japan, which showed his patriotic fervor. The brand became Japan's best known and best selling brand, being synonymous with good quality, middle class and dependability.
• The Market: The market for lacquerware in Japan seems to have matured, with the production steady at 500,000 pieces a year. Nakamura did practically no business outside of Japan. However, early in 1960, when the American interest in Japanese products began to grow, Nakamura received two offers
• The Rose and Crown offer: The first offer was from Mr. Phil Rose, V.P Marketing at the National China Company. They were the largest manufacturer of good quality dinnerware in the U.S., with their “Rose and Crown” brand accounting for almost 30% of total sales. They were willing to give a firm order for three eyes for annual purchases of 400,000 sets of lacquer dinnerware, delivered in Japan and at 5% more than what the Japanese jobbers paid. However, Nakamura would have to forego the Chrysanthemum trademark to “Rose and Crown” and also undertaken to sell lacquer ware to anyone else the U.S. The offer promised returns of $720,000 over three years (with net returns of $83,000), but with little potential for the U.S. market on the Chrysanthemum brand beyond that period.
• The Semmelback offer: The second offer was from Mr. Walter Sammelback of Sammelback, Sammelback and Whittacker, Chicago, the largest supplier of hotel and restaurant supplies in the U.S. They perceived a U.S. market of 600,000 sets a year, expecting it to go up to 2 million in around 5 years. Since the Japanese government did not allow overseas investment, Sammelback was willing to budget $1.5 million. Although the offer implied negative returns of $467,000 over the first five years, the offer had the potential to give a $1 million profit if sales picked up as anticipated.
• Meeting the order: To meet the numbers requirement of the orders, Nakamura would either have to expand capacity or cut down on the domestic market. If he chose to expand capacity, the danger was of idle capacity in case the U.S. market did not respond. If he cut down on the domestic market, the danger was of losing out on a well-established market. Nakamura could also source part of the supply from other vendors. However, this option would not find favor with either of the American buyers since they had approached only Nakamura, realizing that he was the best person to meet the order.
• Decision problem: Whether to accept any of the two offers and if yes, which one of the two and under what terms of conditions?
• To expand into the U.S. market.
• To maintain and build upon their reputation of the “Chrysanthemum” brand
• To increase profit volumes by tapping the U.S. market and as a result, increasing scale of operations.
• To increase its share in the U.S. lacquerware market.
• Profit Maximization criterion: The most important criterion in the long run is profit maximization.
• Risk criterion: Since the demand in the U.S. market is not as much as in Japan.
• Brand identity criterion: Nakamura has painstakingly built up a brand name in Japan. It is desirable for him to compete in the U.S. market under the same brand name
• Flexibility criterion: The chosen option should offer Nakamura flexibility in maneuvering the terms and conditions to his advantage. Additionally, Nakamura should have bargaining power at the time of renewal of the contract.
• Short term returns: Nakamura should receive some returns on the investment he makes on the new offers. However, this criterion may be compromised in favor of profit maximization in the long run.?
• Reject both: React both the offers and concentrate on the domestic market
• Accept RC offer: Accept the Rose and Crown offer and supply the offer by cutting down on supplies to the domestic market or through capacity expansion or both
• Accept SSW: offer; accept the SSW offer and meet it through cutting down on supply to the domestic market or through capacity expansion or both. Negotiate term of supply.
• Reject both: This option would not meet the primary criterion of profit maximization. Further, the objective of growth would also not be met. Hence, this option is rejected.
• Accept RC offer: The RC offer would assure net returns of $283,000 over the next three yeas. It also assures regular returns of $240,000 per year. However, Nakamura would have no presence in the U.S. with its Chrysanthemum brand name The RC offer would entail capacity expansion, as it would not be possible to siphon of 275,000 pieces from the domestic market over three years without adversely affecting operations there. At the end of three years, Nakamura would have little bargaining power with RC as it would have an excess capacity of 275,000 pieces and excess labor which it would want to utilize. In this sense the offer is risky. Further, the offer is not flexible. Long-term profit maximization is uncertain in this case a condition that can be controlled in the SSW offer. Hence, this offer is rejected.
• Accept SSW offer: The SSW offer does not assure a firm order or any returns for the period of contract. Although, in its present form the offer is risky if the market in the U.S. does not pick up as expected, the offer is flexible. If Nakamura were to exhibit caution initially by supplying only 300,000 instead of the anticipated 600,000 pieces, it could siphon off the 175,000 required from the domestic market. If demand exists in the U.S., the capacity can be expanded. With this offer, risk is minimized. Further, it would be competing on its own brand name. Distribution would be taken care of and long-term profit maximization criterion would be satisfied as this option has the potential of $1 million in profits per year. At the time of renewal of the contract, Nakamura would have immense bargaining power.
• Negotiate terms of offer with SSW: The terms would be that NLC would supply 300,000 pieces in the first year. If market demand exists, NLC should expand capacity to provide the expected demand.
• Action Plan: In the first phase, NLC would supply SSW with 300,000 pieces. 125,000 of these would be obtained by utilizing excess capacity, while the remaining would be obtained from the domestic market. If the expected demand for lacquer ware exists in the U.S., NLC would expand capacity to meet the expected demand. The debt incurred would be paid off by the fifth year.
• Contingency Plan:  In case the demand is not as expected in the first year, NLC should not service the U.S. market and instead concentrate on increasing penetration in the domestic market.

“Chevrolet Discover the Unexpected” by Carol H. Williams

This case study explores Chevrolet's “ DTU Journalism Fellows ” program. The case study uses the initials “DTU” to generate interest and encourage readers to learn more. 

Multiple types of media, such as images and videos, are used to explain the challenges faced. The case study concludes with an overview of the achievements that were met.

Key points from the case study include:

• Using a well-known brand name in the title can create interest.
• Combining different media types, such as headings, images, and videos, can help engage readers and make the content more memorable.

The Met emphasizes the website’s features and interface by showcasing each section of the interface individually, allowing the readers to concentrate on the significant elements.

For those who prefer text, each feature includes an objective description. The case study also includes a “Contact Us” call-to-action at the bottom of the page, inviting visitors to contact the company.

Key points from this “The Met” include:

• Keeping the case study simple and clean can help readers focus on the most important aspects.
• Presenting the features and solutions with a visual showcase can be more effective than writing a lot of text.
