difference between problem solving and root cause analysis

Root cause analysis (RCA) is the quality management process by which an organization searches for the root of a problem, issue or incident after it occurs.

Issues and mishaps are inevitable in any organization, even in the best of circumstances. While it could be tempting to simply address symptoms of the problem as they materialize, addressing symptoms is an inherently reactive process that all but guarantees a recurring—and often worsening—series of problems.

Ethical, proactive, well-run companies and organizations with a reactive approach will both encounter problems, but the former will experience fewer and recover faster because they prioritize root cause analyses.     

Root cause analysis helps organizations decipher the root cause of the problem, identify the appropriate corrective actions and develop a plan to prevent future occurrences. It aims to implement solutions to the underlying problem for more efficient operations overall.

Organizations perform root cause analyses when a problem arises or an incident occurs, but there are any number of issues that need an RCA. Triggers for a root cause analysis fall into three broad categories.

When real-world materials or equipment fails in some way (for example, a desktop computer stops working or a component from a third-party vendor delivers substandard performance).

When people make mistakes or fail to complete required tasks (for example, an employee fails to perform regular maintenance on a piece of equipment, causing it to break down).

A breakdown in a system, process or policy people use to make decisions (for example, a company fails to train team members on cybersecurity protocols, leaving the company vulnerable to cyberattacks ).

Organizations can conduct root cause analyses for a range or reasons, from commonplace email service disruptions to catastrophic equipment failures. Regardless of the nature or scope of the issue, performing root cause analysis should include the same fundamental steps.

If you have decided to conduct a root cause analysis, your department or organization is likely experiencing some acute issue, or at least looking to make substantive improvements to a particular process. Therefore, the first step of the root cause analysis process should be identifying and defining the problem that you want to address. Without a clearly defined problem, it is impossible to correctly identify the root causes.

When the department has a clear idea of the problem, it’s time to draft a problem statement spelling out the issue for everyone who will help with the RCA.

Once the issue is identified and clearly articulated to all involved parties, leadership should create a project charter, which will assemble a team to complete the analysis. The team should include a facilitator to lead the team through the analysis and any team members with either personal or professional knowledge of the systems, processes and incidents that you will investigate.

Data collection is the foundation of the problem-solving process. It is vital, at this stage, to find every piece of information that can help you identify contributing factors and ultimately the root causes of the issue. This can include collecting photographs and incident reports, conducting interviews with affected parties and reviewing existing policies and procedures. Some questions that you may want to ask during data collection:

• When did the problem start and how long has it been going on?
• What symptoms has the team observed?
• What documentation does the organization or department must prove that an issue exists?
• How will the issue affect employees and other stakeholders?
• Who is harmed or otherwise affected by the existence of this problem?

This is the most important step in the RCA process. At this point, the team has collected all necessary information and starts to brainstorm for causal factors. Effective root cause analyses require openness to all potential underlying causes of an issue, so everyone on the RCA team should enter the brainstorming stage with an open mind. Avoid attempts to determine root causes until every possibility is identified and vetted; starting the incident investigation process with preconceived notions may bias the results and make it more difficult to determine the real root cause.

Once the RCA team has an exhaustive list of possible causes and contributing factors, it is time to determine the root causes of the issue. Analyze every possible cause and examine the actual impact of each one to figure out which possibilities are the most problematic, which ones have similarities and which ones can be altogether eliminated. Be prepared for the possibility that there are multiple root causes to the issue.

After the team narrows the list of possibilities, rank the remaining potential root causes by their impact and the likelihood they are the root cause of the problem. Leadership will examine and analyze each possibility and collaborate with the RCA team to determine the actual root causes.

Once the team settles on root causes and has laid out all the details of the issue, they must start brainstorming solutions. The solution should directly address the root causes, with consideration for the logistics of executing the solution and any potential obstacles the team may encounter along the way. These elements will comprise the action plan that will help the team address the current problem and prevent recurrences.

While all RCAs will include the same basic steps, there are myriad root cause analysis methods that can help an organization collect data efficiently and effectively. Typically, a company will select a method and use root cause analysis tools, such as analysis templates and software, to complete the process.

The 5 Whys approach is rooted in the idea that asking five “Why?” questions can get you to the root cause of anything. 5 Whys implores problem solvers to avoid assumptions and continue to ask “why” until they identify the root cause of a problem. In the case of a formalized organizational root cause analysis, a team may only need to ask three whys to find the root cause, but they may also need to ask 50 or 60. The purpose of 5 Whys is to push the team to ask as many questions as is necessary to find the correct answers.

A failure mode and effects analysis is one of the most rigorous approaches to root cause analysis. Similar to a risk analysis, FMEA identifies every possibility for system/process failure and examines the potential impact of each hypothetical failure. The organization then addresses every root cause that is likely to result in failure.

Pareto charts combine the features of bar charts and line charts to understand the frequency of the organization’s most common root causes. The chart displays root causes in descending order of frequency, starting with the most common and probable. The team then addresses the root cause whose solution provides the most significant benefit to the organization.

An impact analysis allows an organization to assess both the positive and negative potential impacts of each possible root cause.

Change analyses are helpful in situations where a system or process’s performance changed significantly. When conducting this type of RCA, the department looks at how the circumstances surrounding the issue or incident have changed over time. Examining changes in personal, information, infrastructure, or data, among other factors, can help the organization understand which factors caused the change in performance.

An event analysis is commonly used to identify the cause of major, single-event problem, like an oil spill or building collapse. Event analyses rely on quick (but thorough) evidence-gathering processes to recreate the sequence of events that that led to the incident. Once the timeline is established, the organization can more easily identify the causal and contributing factors.

Also known as a causal factor analysis, a causal factor tree analysis allows an organization to record and visually display—using a causal factor tree—every decision, event or action that led to a particular problem.

An Ishikawa diagram (or Fishbone diagram) is a cause-and-effect style diagram that visualizes the circumstances surrounding a problem. The diagram resembles a fish skeleton, with a long list of causes grouped into related subcategories.

DMAIC is an acronym for the Define, Measure, Analyze, Improve and Control process. This data-driven process improvement methodology serves as a part of an organization’s Six Sigma practices.

This RCA methodology proposes finding the root cause of an issue by moving through a four-step problem solving process. The process starts with situation analysis and continues with problem analysis and solution analysis, concluding with potential problem analysis.

An FTA allows an organization to visually map potential causal relationships and identify root causes using boolean logic.

Barrier analyses are based on the idea that proper barriers can prevent problems and incidents. This type of RCA, often used in risk management, examines how the absence of appropriate barriers led to an issue and makes suggestions for installing barriers that prevent the issue from reoccurring.

Companies that use the RCA process want to put an end to “firefighting” and treating the symptoms of a problem. Instead, they want to optimize business operations, reduce risk and provide a better customer experience. Investing in the root cause analysis process provides a framework for better overall decision-making and allows an organization to benefit from:

Continuous improvement : Root cause analysis is an iterative process, seeking not only to address acute issues, but also to improve the entire system over time, starting with the underlying cause. The iterative nature of root cause analysis empowers organizations to prioritize continuous process improvement.

Increased productivity : Preventing downtime, delays, worker attrition and other production issues within an organization saves employees time, freeing up bandwidth to focus on other critical tasks.

Reduced costs : When equipment breaks down or software bugs cause delays, organizations lose money and workers get frustrated. Root cause analysis helps eliminate the cost of continually fixing a recurring issue, resulting in a more financially efficient operation overall.

Better defect detection : When companies fail to address underlying issues, they can inadvertently affect the quality of the end product. Addressing persistent problems before they snowball protects the organization from revenue and reputational losses that are associated with product defects down the line.

Reduced risks : Improving business processes and systems keeps equipment running safely and helps workers avoid safety hazards in the workplace.

Root Cause Analysis: What It Is & How to Perform One

• 07 Mar 2023

The problems that affect a company’s success don’t always result from not understanding how to solve them. In many cases, their root causes aren’t easily identified. That’s why root cause analysis is vital to organizational leadership .

According to research described in the Harvard Business Review , 85 percent of executives believe their organizations are bad at diagnosing problems, and 87 percent think that flaw carries significant costs. As a result, more businesses seek organizational leaders who avoid costly mistakes.

If you’re a leader who wants to problem-solve effectively, here’s an overview of root cause analysis and why it’s important in organizational leadership.

Access your free e-book today.

What Is Root Cause Analysis?

According to the online course Organizational Leadership —taught by Harvard Business School professors Joshua Margolis and Anthony Mayo— root cause analysis is the process of articulating problems’ causes to suggest specific solutions.

“Leaders must perform as beacons,” Margolis says in the course. “Namely, scanning and analyzing the landscape around the organization and identifying current and emerging trends, pressures, threats, and opportunities.”

By working with others to understand a problem’s root cause, you can generate a solution. If you’re interested in performing a root cause analysis for your organization, here are eight steps you must take.

8 Essential Steps of an Organizational Root Cause Analysis

1. identify performance or opportunity gaps.

The first step in a root cause analysis is identifying the most important performance or opportunity gaps facing your team, department, or organization. Performance gaps are the ways in which your organization falls short or fails to deliver on its capabilities; opportunity gaps reflect something new or innovative it can do to create value.

Finding those gaps requires leveraging the “leader as beacon” form of leadership.

“Leaders are called upon to illuminate what's going on outside and around the organization,” Margolis says in Organizational Leadership , “identifying both challenges and opportunities and how they inform the organization's future direction.”

Without those insights, you can’t reap the benefits an effective root cause analysis can produce because external forces—including industry trends, competitors, and the economy—can affect your company’s long-term success.

2. Create an Organizational Challenge Statement

The next step is writing an organizational challenge statement explaining what the gap is and why it’s important. The statement should be three to four sentences and encapsulate the challenge’s essence.

It’s crucial to explain where your organization falls short, what problems that poses, and why it matters. Describe the gap and why you must urgently address it.

A critical responsibility is deciding which gap requires the most attention, then focusing your analysis on it. Concentrating on too many problems at once can dilute positive results.

To prioritize issues, consider which are the most time-sensitive and mission-critical, followed by which can make stakeholders happy.

3. Analyze Findings with Colleagues

It's essential to work with colleagues to gain different perspectives on a problem and its root causes. This involves understanding the problem, gathering information, and developing a comprehensive analysis.

While this can be challenging when you’re a new organizational leader, using the double helix of leadership —the coevolutionary process of executing organizational leadership's responsibilities while developing the capabilities to perform them—can help foster collaboration.

Research shows diverse ideas improve high-level decision-making, which is why you should connect with colleagues with different opinions and expertise to enhance your root cause analysis’s outcome.

4. Formulate Value-Creating Activities

Next, determine what your company must do to address your organizational challenge statement. Establish three to five value-creating activities for your team, department, or organization to close the performance or opportunity gap you’ve identified.

This requires communicating organizational direction —a clear and compelling path forward that ensures stakeholders know and work toward the same goal.

“Setting direction is typically a reciprocal process,” Margolis says in Organizational Leadership . “You don't sit down and decide your direction, nor do you input your analysis of the external context into a formula and solve for a direction. Rather, setting direction is a back-and-forth process; you move between the value you'd like to create for customers, employees, investors, and your grasp of the context.”

5. Identify Necessary Behavior Changes

Once you’ve outlined activities that can provide value to your company, identify the behavior changes needed to address your organizational challenge statement.

“Your detective work throughout your root cause analysis exposes uncomfortable realities about employee competencies, organizational inefficiencies, departmental infighting, and unclear direction from leadership at multiple levels of the company,” Mayo says in Organizational Leadership .

Factors that can affect your company’s long-term success include:

• Ineffective communication skills
• Resistance to change
• Problematic workplace stereotypes

Not all root cause analyses reveal behaviors that must be eliminated. Sometimes you can identify behaviors to enhance or foster internally, such as:

• Collaboration
• Innovative thinking
• Creative problem-solving

6. Implement Behavior Changes

Although behaviors might be easy to pinpoint, putting them into practice can be challenging.

To ensure you implement the right changes, gauge whether they’ll have a positive or negative impact. According to Organizational Leadership , you should consider the following factors:

• Motivation: Do the people at your organization have a personal desire for and commitment to change?
• Competence: Do they have the skills and know-how to implement change effectively?
• Coordination: Are they willing to work collaboratively to enact change?

Based on your answers, decide what behavior changes are plausible for your root cause analysis.

7. Map Root Causes

The next step in your analysis is mapping the root causes you’ve identified to the components of organizational alignment. Doing so helps you determine which components to adjust or change to implement employee behavior changes successfully.

Three root cause categories unrelated to behavior changes are:

• Systems and structures: The formal organization component, including talent management, product development, and budget and accountability systems
• People: Individuals’ profiles and the workforce’s overall composition, including employees’ skills, experience, values, and attitudes
• Culture: The informal, intangible part of your organization, including the norms, values, attitudes, beliefs, preferences, common practices, and habits of its employees

8. Create an Action Plan

Using your findings from the previous steps, create an action plan for addressing your organizational problem’s root cause and consider your role in it.

To make the action plan achievable, ensure you:

• Identify the problem’s root cause
• Create measurable results
• Ensure clear communication among your team

“One useful way to assess your potential impact on the challenge is to understand your locus of control,” Mayo says in Organizational Leadership , “or the extent to which you can personally drive the needed change or improvement.”

The best way to illustrate your control is by using three concentric circles: the innermost circle being full control of resources, the middle circle representing your ability to influence but not control, and the outermost circle alluding to shifts outside both your influence and control.

Consider these circles when implementing your action plan to ensure your goals don’t overreach.

The Importance of Root Cause Analysis in Organizational Leadership

Root cause analysis is a critical organizational leadership skill for effectively addressing problems and driving change. It helps you understand shifting conditions around your company and confirm that your efforts are relevant and sustainable.

As a leader, you must not only effect change but understand why it’s needed. Taking an online course, such as Organizational Leadership , can enable you to gain that knowledge.

Using root cause analysis, you can identify the issues behind your organization’s problems, develop a plan to address them, and make impactful changes.

Problem, Symptoms & Root Cause Analysis (RCA) Examples

Last updated: 30th Jan, 2024

Have you found yourself stuck in a cycle of solving the same or similar problems over and over again? Ever wondered why some solutions seem to only offer a temporary fix? Have you wondered if you have identified the correct problem or if you are trying to fix one of the symptoms? The key lies in your understanding of how we define problem statements, associated symptoms, root causes , and approach to problem-solving , which is fundamentally rooted in analytical thinking and critical thinking . What exactly is the difference between a problem and its symptoms ? And why is it crucial to conduct a root cause analysis to arrive at a lasting solution?

In both personal and professional spheres (workplace), the ability to identify correct problems and solve them is highly valued. Often, the issues we face are more complex than they first appear. Simply treating the visible symptoms of a problem rarely offers a lasting solution . This is where analytical thinking comes into play . Understanding the difference between a problem and its symptoms, and the role of root cause analysis in identifying and solving the actual problem, is a cornerstone of analytical thinking. This blog aims to throw light on these distinctions and demonstrate the importance of root cause analysis, empowering you to approach problems with a more analytical mindset for enduring solutions.

What is a Problem?

In the context of problem-solving, a “ problem ” is a situation or condition that represents the obstruction for an entity (a person or a thing) to remain in or achieve the desirable or ideal state of being. Problems can also be referred to as “ challenges “. For example, a company aims to achieve a 20% increase in sales revenue by the end of the year. The problems or challenges that the company may face can be some of the following:

• Determining whether the product is not positioned correctly, and then coming up with the most apt product positioning in the manner that matches the needs of the customer
• Analyzing marketing strategy, identifying gaps, and coming up with a marketing strategy to reach out to potential customers matching the product positioning
• Create a potential customer pipeline from which X% can convert into the real ones
• Determine a sales strategy that can help make the sales to the potential customers.
• Determine the most apt communication channels for the potential customer to reach out and enquire
• Need for timely and cost-effective customer service

When the entity is moved to the ideal state (positive change) or most desirable condition, the problem stands resolved . The thing that takes the entity from an undesirable to a desirable state is called the solution .

Often, what we initially identify as a problem turns out to be merely a symptom of the underlying problem (or root cause). Symptoms of a problem can be understood as the indicators of the underlying “real problem”. Unlike symptoms , which are mere indicators or manifestations of the problem or real problem , the real problem itself is the root cause that leads to the observable symptoms. It is very important to discern between the symptom and the real problem. If not done well, there is a risk of solving the “ symptoms ” when you think that you are solving the problems.

Here is a problem vs symptom example . When you have a cough problem, it is important to differentiate between whether a cough is a problem and take medicines for it, or, if a cough is due to some lung problem and take the medicine to cure that lung-related problem.

Here is another example to understand problem vs symptoms . Let’s say, when a business is experiencing declining sales, one may call out the problem as “declining sales”. However, the “declining sales” is merely a symptom. The actual problem or the root cause can be traced to poor customer service based on the root cause scenario. It is the core issue that needs to be identified and resolved to bring about a positive change.

What are Symptoms? What’s the difference between Symptoms & Problems?

Symptoms of a problem are the observable effects or indicators that point towards an existing problem ; they are not the problem themselves. These are the signs that something is wrong, but they often don’t reveal the underlying cause. Understanding the distinction between symptoms and the actual problem is crucial because treating symptoms won’t eliminate the root issue.

The following are some of the problem vs symptom, or, symptom vs root cause examples :

• On the personal front, let’s consider recurring headaches. You might think the problem is the headache itself, but that is a symptom. The real problem or the root cause could be anything from dehydration to stress. Taking painkillers will temporarily relieve the headache but won’t resolve the underlying issue causing it.
• In a business setting, consider declining sales. At first glance, you might think the problem is the product or its pricing. However, declining sales are a symptom. The actual problem or the root cause could be poor customer service or ineffective marketing. Addressing only the symptom by slashing prices may bring a temporary boost in sales but won’t provide a long-term solution

By identifying and treating the root cause or actual problem rather than its symptoms , you can find a lasting solution that prevents the issue from recurring. This approach not only saves time and resources but also promotes better analytical thinking and decision-making.

The following are some of the key differences between symptoms and the problems or root cause :

• Symptoms when resolved can reappear after some time. Problems or root causes when resolved stay resolved.
• Symptoms are evident . They can be easily identified. Problems or root causes are difficult to unearth or determine. They can be deep-rooted .
• A problem can manifest in the form of many symptoms.

What is Root Cause Analysis (RCA)? Why is it needed?

Root Cause Analysis (RCA) is a structured approach for identifying the underlying causes of what is referred to as the problem (symptoms on the surface) . The goal is to find out what, how, and why something happened, thereby preventing recurrence. It’s like a detective’s investigation to find the “criminal” causing the symptoms, which in this context, are the undesired outcomes or challenges.

RCA is valuable because it helps you go beyond treating symptoms to find the real problem. It’s the difference between mopping up a water leak and fixing the pipe that’s leaking. By focusing on the root cause, you not only solve the immediate problem but also prevent similar issues in the future.

For instance, if a company is facing high employee attrition, addressing the symptoms might involve conducting exit interviews and providing compensation packages. However, a root cause analysis may reveal that the real issue is a toxic work culture or poor management. Addressing these root causes would lead to more effective and lasting solutions.

There are various methods for conducting RCA, and the choice often depends on the complexity of the problem and the resources available. Some popular techniques include:

• The 5 Whys : This method involves asking “Why?” repeatedly (usually five times) to drill down into the layers of a problem.
• Fishbone diagram : This visual tool allows you to categorize potential causes of a problem, helping to identify the root cause systematically.
• Analytical thinking : One can break down problems into sub-problems and continue this process until one reaches to most fundamental problems.
• First principles thinking : One can analyze a problem based on final, formal, material, and efficient causes and then repeat the process.

By understanding and applying these RCA techniques, you can develop a more analytical approach to problem-solving, thereby addressing issues at their core and preventing future recurrence.

Process for Arriving at the Root Cause of Symptoms / Problems

The following represents the process for arriving at the root cause of stated symptoms or problems:

• Distinguish Between Problem and Symptom : Your first task is to determine if what has been stated is the problem or merely a symptom of something deeper. For instance, experiencing a headache is generally a symptom, not the underlying problem itself.
• Identify the Underlying Problem : If what is stated is a problem, well and good. However, if you’ve identified a symptom, your next step is to discover what the problem could be. For example, if you’re dealing with headaches, the underlying issue may be something like ill-health.
• List All Observable Symptoms : Expand your perspective by identifying all the symptoms related to the issue at hand. This will give you a more comprehensive view and may provide additional clues about the root cause.
• Generate Cause Hypotheses for Stated Symptoms : Formulate hypotheses for what could be causing the symptoms for the identified problem. This step is essentially a diagnosis . Employ techniques like the “Five Whys” to dig deeper and identify potential underlying causes.
• Test Each Hypothesis to identify the real root cause : For each hypothesized cause, perform diagnostic tests to either validate or negate it. This could be in the form of data collection, interviews, or even controlled experiments. The aim is to gather evidence that either supports or refutes each hypothesis.
• Identify the Root Cause : After you’ve rigorously tested each hypothesis, you should be able to pinpoint one root cause that stands out as the most likely “actual problem” or “root cause” of the issues you’re observing.

Defining Problem Statement

The problem statement should consist of information related to the following:

• Ideal state: The ideal state outlines what the perfect scenario would look like once the problem is solved. This sets the vision and provides a clear goal for problem-solving efforts.
• What : Define the problem precisely. You can use root cause analysis to dig deep into the “What” aspect.
• Why : Identify why the problem is important.
• Where : Specify the areas or departments affected.
• When : Determine when the problem occurs or comes to notice.
• Who : Note who is impacted, either directly or indirectly.
• How : Describe the nature of the impact, be it financial, operational, or emotional.
• Outcome as a result of problem resolution : The outcome section elaborates on what success looks like, linking back to the ideal state. It can include quantitative and qualitative measures that indicate the problem has been solved.

Understanding the difference between a problem and its symptoms is the cornerstone of effective problem-solving. Many times, organizations or individuals get sidetracked by addressing symptoms without ever reaching the core issue. By employing a structured approach, like distinguishing between problems and symptoms, identifying all associated symptoms, formulating hypotheses for root causes , and rigorously testing these hypotheses, you set the stage for finding the actual root cause of the problem. This not only saves time and resources but also leads to long-lasting solutions.

From an analytical thinking standpoint, mastering this approach equips you with a crucial skill set. It helps you avoid the pitfalls of surface-level solutions and encourages a deeper understanding of challenges. So the next time you’re confronted with a “problem,” take a step back and consider: Is this the real issue, or is it just the tip of the iceberg? The answer to this question could be the first step toward effective and sustainable problem-solving.

Better problem solving with root cause analysis (with template)

If you walk into your kitchen to find your favorite vase smashed on the floor, it might be safe to assume that the grinning cat nearby was the root cause of this problem. If only it was this simple in business and we could just say “the cat did it.” Product problems are often much more complex and connected to a variety of root causes.

If you think of a weed, the surface is only the problem you can immediately see. However, if you cut the weed from the ground level, it’s likely to grow back from the root. This is just like fixing product problems with a band-aid with little to no investigation of a root cause — it’s likely to return.

These types of problems need a more thorough root cause analysis (RCA) to determine how, and why the problem happened, and how to prevent it in the future.

What is root cause analysis?

Root cause analysis is a tool you can utilize when determining the true cause of a problem. You might have assumptions about what the cause of a problem might be or experience biases towards one as the main cause.

Performing a root cause analysis can help you determine what the underlying causes of a problem are to help address a more impactful and valuable solution:

What are the 4 steps in a root cause analysis?

When you’re trying to uncover the roots of a problem, it can be daunting to figure out where to start. The process to conduct a root cause analysis can be broken down into a few easy steps:

• Define the problem
• Identify and map the problem causes
• Identify the evidence that supports your causes
• Create a root cause analysis report and set up your action plan

1. Define the problem

A clear definition of the problem is the first step. Sometimes problems are easy to identify, like a broken link. More often, problems can be abstract and need clarification, like a decrease in overall purchases through a site or an increase in bugs reported.

Here are some more examples of problems:

• A 20 percent drop in customer purchases placed from the shopping cart page from the previous week
• 60 percent of customers on hold end up dropping their call and, as a result, the company has experienced a decrease in NPS scores
• A 40 percent increase of customer reported issues with using the folders feature in a CRM
• A 15 percent decrease in user engagement with a core feature on a social media site

It’s also critical to understand how to define a problem:

2. Identify and map the problem causes

Using tools like a fishbone analysis and the Five Whys framework can help you put together causes and start to categorize themes of the problem. When going through a Five Whys diagram, try to come up with a few alternate pathways and you might notice overlapping areas.

Each example of a Five Whys diagram is accurate, but only looking at one cause can prevent you from understanding the fuller picture. For example, there was more than one reason why the Fyre Festival failed and it’s important to identify overlapping themes to avoid leaning on only one cause:

In a product example, there might be numerous reasons why session times have decreased, or user reported bugs are up.

After evaluating the size, impact, general cause themes, and urgency of the problem, you’ll have a better understanding of how much effort will be needed for the analysis. The larger the problem on the surface, the more underlying causes you might find. Even simple problems can sometimes have numerous causes to consider and you need to determine how in-depth you need to dig to “unroot” the causes.

It’s also critical to check all your bases. Once you have evaluated and categorized the different potential causes to a problem, use the following as a checklist to ensure you’re covering all areas of where and how this problem happened. Be sure to identify any changes or recent events that might have occurred that could have impacted the problem.

• Demographics : is the problem happening to one specific demographic? Only happening to iPhone users? Users in a specific location?
• Time specific : when did the problem happen? Is it continuing to happen? Did the problem only occur during a specific time? You might discover that the problem is related to a time-specific cause, like a release or outage
• User journey : did anything change within the user journey? Map the workflow to determine if any new developments have occurred
• External factors : is this an issue with a third party integration? Did a competitor launch a successful new feature that might be taking business from you? Some of these external factors could be out of your control, but important to recognize
• Internal factors : how many feature releases happened during this time frame? Was there any product downtime or maintenance at that time?

3. Identify the evidence that supports your causes

Collecting evidence is a key part of a root cause analysis. Without evidence, your problem causes are based on assumptions and potentially harmful biases.

Start evaluating any data you might have available. Using session replay tools like LogRocket can help you collect evidence of the problem. Here are a couple of examples of the type of data that can be used to collect evidence:

• User count — number of users impacted by the problem
• Usage — daily, weekly, or monthly active users and a decrease or increase in session time
• Decrease or increase in events — for example, a decrease in users selecting the Add to cart button from a page or an increase in error pages
• Error tracking and user frustration — tools like LogRocket can help track where things are going wrong in your product and surface critical issues
• Qualitative evidence — run user interviews or user-submitted feedback with tools like Loom. Are multiple users running into the same roadblock? Are you seeing the same complaint from multiple users in feedback tickets?

4. Create a root cause analysis report and set up your action plan

Collect your evidence and root cause evaluation into an RCA template. Once you have your causes identified and your discovery efforts into one root cause analysis report, you can start creating a plan to address the problem and prevent it from happening in the future.

Over 200k developers and product managers use LogRocket to create better digital experiences

Collaborate with a team to brainstorm solutions and discuss which options might address multiple causes. Evaluate if you need both a short-term and long-term solution, depending on the level of effort and urgency required. As part of your analysis report, discuss how you can avoid this problem again in the future and any other risk mitigation plans.

Root cause analysis template

You can use this root cause analysis template on Google Sheets to organization your investigation, collect your evidence, and share with your team to determine next step solutions:

Root cause analysis example

Below is an RCA for Company B, a tax preparation product that experienced an increase in dropped customer calls.

Company B experienced an increase of 60 percent of customers on hold that ended up dropping their call. They also experienced an increase in NPS dissatisfaction and have concerns about losing customers.

After going through a root cause analysis, they discovered an 80 percent increase in user calls during tax season. This increase of call volume indicated much longer wait times to speak to a live agent.

After investigating some of the customer call reasons, they discovered that numerous customers had simple questions that could be answered quickly without too much support.

Company B gathered call logs that confirmed their suspicions. They brought the logs together that demonstrated the simplicity of repeated questions and gathered records of customers that dropped off after a certain amount of time on the phone.

Company B implemented a conversational AI chatbot that could answer generic questions and direct more complex questions to a live agent. Further, they implemented tooltips throughout the tax process flow to help users that appeared to be stuck.

Through the RCA process, you might discover that some parts of the user’s experience are confusing and create a plan to address minor UI challenges.

These solutions helped Company B improve their accessibility and scalability needs during an increase in call volume, without having to add more employee support. Going forward, Company B can plan to monitor call times and continuously evaluate customer service topics to determine where users might need further support and guidance in the future:

Common mistakes to avoid

There are a number of easy-to-fall-into traps when performing root cause analysis, including:

• Don’t rely on assumptions when determining root causes. Use evidence to support to disprove a cause
• Don’t limit your investigation. Go beyond one Five Why framework and be sure to exhaust all possibilities to avoid leaning on the first cause
• Don’t rely on the first idea — come up with multiple solutions to solve a problem
• Don’t work alone. Collaborating with a team will help you come up with a variety of potential solutions or new opportunities
• Don’t think this is a one-time thing. Prepare for the future and discuss risk management and mitigation if you expect this problem to happen again, especially with issues that might be related to factors out of your control. What’s the worst that can happen, and what can we do about it to make sure the problem is addressed quickly with minimal interruption?

Final thoughts

A root cause analysis can be a great tool to help you uncover the true causes of a problem and reduce any reliance on assumptions or biases. With the right investigation and evidence collection, you can learn more about how and why a problem happened and identify causes below the surface.

RCA can ensure your solutions address the root problem and help you better plan for the future.

Root Cause Analysis: A Complete Guide With Examples (2023)

Root Cause Analysis (RCA) is not just a structured method of problem-solving; it's a vital component of organisational leadership. The goal of RCA is to fully understand what caused an issue, allowing for effective corrective actions.

One of the first steps in a successful RCA is identifying performance or opportunity gaps within an organisation. These gaps reflect ways in which an organisation falls short or fails to deliver on its capabilities. RCA helps in pinpointing these gaps, thereby allowing for more targeted solutions.

This article will take you through the benefits of RCA and the three basic types of root causes behind workplace incidents. We’ll then explore the two popular methodologies for RCA and how you can use the RCA methodology to identify them. 

Finally, we’ll share tools and best practices to help you implement a robust RCA framework so you can develop a comprehensive problem-solving process for safety and risk management in your organisation.

Read on to discover how RCA can revolutionise your approach to problem-solving and risk management.

The benefits of Root Cause Analysis (RCA)

Without a structured RCA framework for resolving incidents, organisations risk implementing superficial quick fixes that may address some of the symptoms but not the core problems.

An effective RCA methodology helps an organisation's Health & Safety (H&S) team to identify the root causes of a reported incident in the workplace, which is essential to assign effective preventive or corrective actions . Implementing this framework have many benefits:

• Save time, money, and resources because they can identify and invest in the right preventive and corrective actions.
• Prevent the incident from recurring because they can correct the factors causing the issues.
• Prevent more damage or injury caused by a recurring incident.
• Prevent more downtime caused by a recurring incident.
• Boost productivity because they don’t have to revisit the same incident and spend extra time trying to solve the underlying issues.

The three basic types of root cause

There are three fundamental types of root causes:

• Environmental root cause These are causes related to external factors such as moisture levels, weather, or geography.
• Individual root cause These are causes related to an individual’s behaviour, personal choices, ability, or circumstance.
• Organisational root cause These are causes involving internal organisational structure or processes.

The two popular RCA frameworks

A study by Baylor University Medical Center Proceedings identified two popular RCA frameworks. We will cover each one with an example.

#1: The "5 Whys" Method

This is perhaps the most popular RCA technique because of its simplicity. The method is to ask why something happened at least five times. Here’s an example of how it works.

Incident: A construction worker fell and broke his arm.

• “Ask Why” #1: Why did he fall? Answer: He tripped on a wire
• “Ask Why” #2: Why was the wire on the ground? Answer: It was an extension wire needed to supply power to a tool on the other side.
• “Ask Why” #3: Why was the wire pulled across a thoroughfare? Answer: There was no power socket on the other side.  
• “Ask Why” #4: Why is there only one power socket in that area? Answer: There aren’t enough portable generators on the site.
• “Ask Why” #5: Why aren’t enough portable generators on the site? Answer: The application requesting the budget to rent a few more portable generators is pending approval.

Using this RCA technique, we’ve identified the actual root cause to be an organisational root cause. The solution for the organisation is to improve the process of approving budgets. 

Speeding up the process of approving budgets doesn’t just help prevent future similar incidents. It may also bring the added benefit of improving productivity when construction workers can quickly get what they need to perform their tasks.

Without using this RCA technique, one could have soon concluded that it was solely an environmental or individual root cause. Any corrective actions in these areas are likely to be ineffective or short-term.

#2: Causal Tree

A causal tree is used to evaluate other possible causes that contributed to the incident. This can help organisations identify other possible preventive or corrective actions. Here’s an example of how a causal tree could look like for the same incident example above:

Organisations can explore other possible root causes that need addressing using a causal tree. This RCA methodology is beneficial for identifying root causes across environmental, individual, and organisational categories. Another advantage of using the causal tree framework is that it allows organisations to implement short-term solutions to prevent incidents while they take more time to find answers to more prominent issues. For example, the construction company can implement the short-term solution of placing warning signs in front of extended wires on the ground. Meanwhile, the organisation will look into solving the other root causes identified, such as improving the budget approval process and hazard reporting training.

Common Mistakes to Avoid in Root Cause Analysis

Root Cause Analysis (RCA) can be highly effective in addressing workplace safety issues when done correctly. 

However, there are some common mistakes that organisations make when conducting RCA.

Mistake #1: Jumping to conclusions

One of the most common mistakes is jumping to conclusions without thoroughly examining the available information. This often leads to implementing quick fixes that do not address the root cause of the problem.

Tip: Ensure that you take the time to gather all relevant information and systematically work through the RCA process to identify the underlying cause.

Mistake #2: Focusing only on individual errors

Another mistake is solely blaming individuals for incidents without considering the broader organisational context. This can lead to a culture of blame and an unwillingness to report incidents in the future.

Tip: While it is essential to consider individual factors, also examine organisational root causes and environmental factors that may have contributed to the incident. This will help to create a more comprehensive understanding of the issue and lead to more effective solutions.

Mistake #3: Neglecting to involve the right people

One common mistake organisations make is neglecting to involve the right people in the RCA process. A successful RCA requires input from various stakeholders, including employees directly involved in the incident, supervisors, and management. Collaborative analysis helps in collecting a variety of viewpoints and promotes a sense of collective accountability for workplace safety.

Tip: Involving all pertinent stakeholders in the RCA process is crucial, as it aids in collecting a variety of viewpoints and promotes a sense of collective accountability for workplace safety.

Mistake #4: Inadequate documentation

Poor documentation of the RCA process and its outcomes can lead to a lack of accountability and hinder the implementation of corrective actions.

Tip: Document every step of the RCA process, including the incident description, investigation, root cause identification, and proposed corrective actions. This will help ensure that all stakeholders are aware of their responsibilities and can track the progress of the implemented solutions.

Mistake #5: Failing to follow up on corrective actions

Implementing corrective actions is only one part of the RCA process. Organisations sometimes fail to follow up on these actions, which can lead to a recurrence of the incident or issue.

Tip: Establish a system to monitor the progress of corrective actions and evaluate their effectiveness. Regularly review the implemented solutions and make any necessary adjustments to ensure that the root cause is fully addressed and the risk of recurrence is minimised.

How to implement a robust RCA framework 

To enhance workplace safety, it is crucial to establish a strong RCA framework within your organisation.

These are the following steps to implement such a framework:

• Train the H&S team on how to use the different types of RCA frameworks.
• Make it easy for employees to report incidents and other events like near misses.
• Update the new employee training, health and safety training, and SOP guides on submitting incident reports and conducting RCA.
• Conduct regular health and safety training sessions.
• Creating an action plan: outline the steps to be taken, the stakeholders involved, and the timeline for implementation

The importance of high-quality incident and hazard reports 

The effectiveness of any Root Cause Analysis (RCA) relies heavily on the input data's accuracy and quality. Therefore, it is imperative to have a reliable incident reporting system in place to ensure the provision of high-quality input data.

Here are the characteristics of a high-quality incident report:

• Records the incident's time, date, and location.
• Is honest, clear, and concise.
• Provides accurate information that doesn’t leave out important facts.
• Provide as much context as possible.
• It is written in a first-person, objective observation of what happened, not what they think might have happened.

To write an accurate incident report, employees should be encouraged to start writing the report as soon as possible. 

Delaying writing the report can lead to inaccurate reports or reports without enough detail because the memory gets fuzzy. Whenever possible or relevant, employees should also attach photos for additional context.

To help you navigate the complexities of incident reporting, we strongly recommend downloading our free checklist and comprehensive guide .

Best practices to improve incident reporting and RCA

One of the best practices to improve the quality of incident reports is digitalising the incident reporting process. 

Here’s an example of how Vatix’s incident reporting systems can improve the quality of workplace incident reports and RCA.

• Higher quality incident reports Our mobile platform makes it easy for employees to report an incident from anywhere without the friction of filling out and submitting a paper form. Facilitating on-the-spot reporting for employees minimises the likelihood of postponing or neglecting to report incidents or other events. Faster reporting of incidents also improves the quality of the report. Employees are more likely to record details with better descriptions and upload photos directly from their mobile devices, improving the data needed for an effective RCA.
• Customise incident types to an organisation’s specific needs Our incident reporting software allows organisations to customise the types of incidents employees can report. These templates eliminate the need to print out, distribute, and file multiple forms.
• Easily customise the incident reporting template to capture relevant information. With our incident reporting software, organisations can customise the incident reporting forms to ensure employees submit all required and relevant information. 
• Real-time reporting and location tracking for faster response Paper-based incident reporting causes a lot of delays and it can take hours before supervisors or managers can view the incident reports. With real-time mobile incident reporting, employees can submit incidents on-the-spot and the H&S team will be alerted with a location so they can respond to the incident within minutes. In some cases, faster response time with location tagging can be the difference between life and death.
• Easy to get more context at a glance Unlike manual paper-and-pen incident reporting forms, employees can easily add photographs to the incident report directly from their mobile. The incident reporting app also logs the location and provides visual maps for additional context at a glance.

Improve workplace health & safety processes

By combining mobile incident reporting with an effective RCA strategy, organisations can respond to incidents faster and more effectively to create a positive safety culture, leading to increased productivity and decreased risk of accidents and injuries.

Root Cause Analysis

Tracing a problem to its origins.

By the Mind Tools Content Team

In medicine, it's easy to understand the difference between treating the symptoms and curing the condition. A broken wrist, for example, really hurts! But painkillers will only take away the symptoms; you'll need a different treatment to help your bones heal properly.

But what do you do when you have a problem at work? Do you jump straight in and treat the symptoms, or do you stop to consider whether there's actually a deeper problem that needs your attention? If you only fix the symptoms – what you see on the surface – the problem will almost certainly return, and need fixing over and over again.

However, if you look deeper to figure out what's causing the problem, you can fix the underlying systems and processes so that it goes away for good.

What Is Root Cause Analysis?

Root Cause Analysis (RCA) is a popular and often-used technique that helps people answer the question of why the problem occurred in the first place. It seeks to identify the origin of a problem using a specific set of steps, with associated tools, to find the primary cause of the problem, so that you can:

• Determine what happened.
• Determine why it happened.
• Figure out what to do to reduce the likelihood that it will happen again.

RCA assumes that systems and events are interrelated. An action in one area triggers an action in another, and another, and so on. By tracing back these actions, you can discover where the problem started and how it grew into the symptom you're now facing.

You'll usually find three basic types of causes:

• Physical causes – Tangible, material items failed in some way (for example, a car's brakes stopped working).
• Human causes – People did something wrong, or did not do something that was needed. Human causes typically lead to physical causes (for example, no one filled the brake fluid, which led to the brakes failing).
• Organizational causes – A system, process or policy that people use to make decisions or do their work is faulty (for example, no one person was responsible for vehicle maintenance, and everyone assumed someone else had filled the brake fluid).

RCA looks at all three types of causes. It involves investigating the patterns of negative effects, finding hidden flaws in the system, and discovering specific actions that contributed to the problem. This often means that RCA reveals more than one root cause.

You can apply RCA to almost any situation. Determining how far to go in your investigation requires good judgment and common sense. Theoretically, you could continue to trace the root causes back to the Stone Age, but the effort would serve no useful purpose. Be careful to understand when you've found a significant cause that can, in fact, be changed.

Frequently Asked Questions

Why is root cause analysis important.

RCA allows you to get to the true source of a problem, and stop it in its tracks. This is more effective than simply remedying the symptoms. By identifying and alleviating the root cause of a problem, you can prevent an issue from occurring again in the future.

What is the 5 Whys technique?

The 5 Whys is a common problem-solving technique. You simply ask "why" something is happening until you get to the source of the issue.

Though a useful tool in its own right, the 5 Whys method can be used during a Root Cause Analysis to help you quickly identify different causal factors of a problem.

What are the five steps of a root cause analysis?

RCA has five identifiable steps:

• Define the problem.
• Collect data.
• Identify causal factors.
• Identify root cause(s).
• Implement solutions.

Read on to learn how to carry out each step in your own root cause analysis.

How to Perform a Root Cause Analysis

Step one: define the problem.

Ask yourself the following:

• What do you see happening?
• What are the specific symptoms?

Step Two: Collect Data

• What proof do you have that the problem exists?
• How long has the problem existed?
• What is the impact of the problem?

You need to analyze a situation fully before you can move on to look at factors that contributed to the problem. To maximize the effectiveness of your RCA, get together everyone – experts and frontline staff – who understands the situation. People who are most familiar with the problem can help lead you to a better understanding of the issues.

A helpful tool at this stage is CATWOE . With this process, you look at the same situation from different perspectives: the Customers, the people (Actors) who implement the solutions, the Transformation process that's affected, the World view, the process Owner, and Environmental constraints.

Step Three: Identify Possible Causal Factors

• What sequence of events leads to the problem?
• What conditions allow the problem to occur?
• What other problems surround the occurrence of the central problem?

During this stage, identify as many causal factors as possible. Too often, people identify one or two factors and then stop, but that's not sufficient. With RCA, you don't want to simply treat the most obvious causes – you want to dig deeper.

5 Whys Root Cause Analysis

Use the 5 Whys tool to identify the root causes of a problem quickly. Just ask "Why?" until you reveal each causal factor.

If you need a more in-depth technique to identify possible factors, try these other tools that can help you dig further into each cause:

• Appreciation – Use the facts and ask "So what?" to determine all the possible consequences of a fact.
• Drill Down – Break down a problem into small, detailed parts to better understand the big picture.
• Cause and Effect Diagrams – Create a chart of all of the possible causal factors, to see where the trouble may have begun.

Step Four: Identify the Root Cause(s)

• Why does the causal factor exist?
• What is the real reason the problem occurred?

Use the same tools you used to identify the causal factors (in Step Three) to look at the roots of each factor. These tools are designed to encourage you to dig deeper at each level of cause and effect.

Step Five: Recommend and Implement Solutions

• What can you do to prevent the problem from happening again?
• How will the solution be implemented?
• Who will be responsible for it?
• What are the risks of implementing the solution?

Analyze your cause-and-effect process, and identify the changes needed for various systems. It's also important that you plan ahead to predict the effects of your solution. This way, you can spot potential failures before they happen.

One way of doing this is to use Failure Mode and Effects Analysis (FMEA). This tool builds on the idea of risk analysis to identify points where a solution could fail. FMEA is also a great system to implement across your organization; the more systems and processes that use FMEA at the start, the less likely you are to have problems that need RCA in the future.

Impact Analysis is another useful tool here. This helps you explore possible positive and negative consequences of a change on different parts of a system or organization.

Another great strategy to adopt is Kaizen , or continuous improvement. This is the idea that continual small changes create better systems overall. Kaizen also emphasizes that the people closest to a process should identify places for improvement. Again, with Kaizen alive and well in your company, the root causes of problems can be identified and resolved quickly and effectively.

Tips for Performing Effective Root Cause Analysis

Collaborate with other teams . Gain a diverse range of experiences and expertise by working with relevant people from other teams. They can likely offer different perspectives that will help to find the various causes of the problem.

Don’t play the blame game! Root cause analysis is a tool that helps you and your team overcome problems, but it shouldn’t be used to criticize or blame someone. Instead, try to create a blame-free culture, so that your co-workers feel confident in sharing ideas and insights. This will help you to diagnose the issue quickly and effectively.

Keep your questions open-ended. Leave any assumptions you have about the potential causes of the problem at the door. RCA is a chance to look at a problem with fresh eyes, so use open-ended questions as you work through the five steps. This will allow you to reveal things you didn’t already know, and find the most effective solution.

• Root Cause Analysis is a useful process for understanding and solving a problem.
• Figure out what negative events are occurring. Then, look at the complex systems around those problems, and identify key points of failure. Finally, determine solutions to address those key points, or root causes.
• You can use many tools to support your RCA process. Cause and Effect Diagrams and 5 Whys are integral to the process itself, while FMEA and Kaizen help minimize the need for RCA in the future.
• As an analytical tool, RCA is an essential way to perform a comprehensive, system-wide review of significant problems as well as the events and factors leading to them.

What Is The Difference Between Root Cause Analysis And Problem Solving?

Manuela Brown

16. February 2023

Root cause analysis and problem solving are two concepts that are commonly used in the field of planning and activities. While both of these terms may seem similar, they are distinct concepts that serve different purposes. In this blog post, we will explore the definitions and benefits of root cause analysis and problem solving, as well as the distinctions between the two.

Root cause analysis is a systematic process for identifying the underlying cause or causes of a problem. It is a problem-solving method that focuses on finding the root cause of a problem in order to develop effective solutions. Problem solving, on the other hand, is a broader concept that involves identifying and resolving problems in general.

In the following sections, we will explore the concepts of root cause analysis and problem solving in more detail, including their definitions, benefits, and differences. By understanding the distinctions between these two approaches, organizations can determine which approach is best suited to their specific needs and goals, and implement more effective solutions to their problems.

Table of Contents

What Is Root cause analysis?

Root cause analysis is a systematic process for identifying the underlying cause or causes of a problem. It is a problem-solving method that aims to find the root cause of a problem in order to develop effective solutions. The goal of root cause analysis is to identify the underlying cause of a problem, rather than just treating the symptoms.

The process of root cause analysis typically involves several steps. The first step is to define the problem and gather data about it. The next step is to identify potential causes of the problem, using tools such as the 5 Whys or Fishbone diagram. The third step is to evaluate and test each potential cause, in order to determine which one is the true root cause. Finally, the fourth step is to develop and implement solutions to address the root cause.

The benefits of root cause analysis include increased efficiency and productivity, reduced costs, and improved customer satisfaction. By identifying the root cause of a problem, organizations can develop more effective solutions that address the underlying cause, rather than just treating the symptoms. This can lead to more long-lasting and impactful improvements, as well as a reduction in recurring problems.

It is important to note that root cause analysis is a systematic and ongoing process, rather than a one-time event. By continually evaluating and improving their processes, organizations can stay competitive and adapt to changing market conditions. Root cause analysis can be used in a variety of industries and settings, including manufacturing, healthcare, and service industries.

What Is Problem solving?

Problem solving is a broad concept that refers to the process of identifying and resolving problems. It is a critical skill for individuals and organizations to have in order to achieve success. Problem solving involves identifying a problem, generating potential solutions, evaluating and selecting a solution, and implementing and evaluating the effectiveness of the chosen solution.

The benefits of problem solving are numerous, including increased efficiency, productivity, and innovation. By identifying and resolving problems, organizations can improve their processes and outcomes, and stay competitive in a rapidly changing business environment. Problem solving is also an essential skill for individuals, as it can help them overcome challenges and achieve their goals.

Effective problem solving requires a number of skills and techniques, including critical thinking, creativity, and collaboration. It is important to approach problem solving in a systematic and organized way, and to consider multiple perspectives and potential solutions. By using a structured approach to problem solving, individuals and organizations can improve their problem-solving skills and achieve better outcomes.

Problem solving can be used in a variety of settings and industries, including healthcare, education, business, and manufacturing. It is an ongoing process that requires continual evaluation and improvement, in order to stay adaptable and responsive to changing circumstances. By mastering the skill of problem solving, individuals and organizations can achieve greater success and reach their full potential.

What Are The Similarities Between Root cause analysis And Problem solving?

While root cause analysis and problem solving are distinct concepts, they do share some commonalities. In this section, we will explore the similarities between the two approaches.

Both root cause analysis and problem solving are focused on identifying and resolving problems. Root cause analysis aims to identify the underlying cause of a problem, while problem solving involves identifying and resolving problems in general.

Both root cause analysis and problem solving require a commitment to data-driven decision making. Root cause analysis involves collecting and analyzing data in order to identify the true root cause of a problem, while problem solving requires the use of data to inform the problem-solving process.

Both root cause analysis and problem solving prioritize continuous improvement. Root cause analysis is an ongoing process of evaluation and feedback, in order to continually improve organizational performance. Problem solving is also an iterative process that requires ongoing evaluation and improvement, in order to stay adaptable and responsive to changing circumstances.

Both root cause analysis and problem solving are collaborative processes. Both approaches require input and involvement from a variety of stakeholders, in order to identify the best solutions and implement changes effectively. Collaboration is essential for creating a culture of continuous improvement and achieving lasting success.

In summary, while root cause analysis and problem solving are distinct approaches to identifying and resolving problems, they do share some commonalities. Both approaches require a commitment to data-driven decision making, prioritize continuous improvement, and are collaborative processes. By understanding the similarities and differences between these two approaches, organizations can determine which approach is best suited to their specific needs and goals, and improve their problem-solving and decision-making skills.

What Are The Differences Between Root cause analysis And Problem solving?

While root cause analysis and problem solving share some commonalities, there are also some key differences between the two approaches. In this section, we will explore the differences between root cause analysis and problem solving.

Root cause analysis is a specific approach to problem solving that is focused on identifying the underlying cause of a problem. Problem solving, on the other hand, is a broader concept that involves identifying and resolving problems in general.

Root cause analysis is a more systematic and structured approach than problem solving, and involves several distinct steps, including defining the problem, gathering data, identifying potential causes, and developing and implementing solutions. Problem solving, while also a structured process, may be less rigorous in its approach, and may involve a more iterative and flexible approach to problem solving.

Root cause analysis is typically used for more complex problems, while problem solving can be used for a range of issues, from simple to complex. Root cause analysis is particularly useful when the underlying cause of a problem is unclear or difficult to identify, and when it is important to develop long-lasting solutions.

Another key difference between root cause analysis and problem solving is that root cause analysis is focused on prevention, while problem solving may be more reactive in nature. Root cause analysis seeks to identify and address the underlying cause of a problem, in order to prevent it from occurring in the future. Problem solving, while also focused on identifying and resolving problems, may not always prioritize prevention.

In summary, while root cause analysis and problem solving share some similarities, there are also key differences between the two approaches. Root cause analysis is a more systematic and rigorous approach, focused on identifying the underlying cause of a problem and preventing it from recurring. Problem solving, while also structured, may be more flexible and iterative in its approach, and can be used to resolve a range of issues, from simple to complex.

Conclusion: Root cause analysis Vs. Problem solving

In conclusion, root cause analysis and problem solving are two distinct approaches to identifying and resolving problems in the field of planning and activities. While both approaches share some similarities, there are also key differences between the two.

Root cause analysis is a systematic and rigorous approach that is focused on identifying the underlying cause of a problem, in order to prevent it from recurring. Problem solving, while also structured, may be more flexible and iterative in its approach, and can be used to resolve a range of issues, from simple to complex.

Effective problem-solving skills are essential for individuals and organizations to achieve success in a rapidly changing business environment. By understanding the distinctions between these two approaches, organizations can determine which approach is best suited to their specific needs and goals, and implement more effective solutions to their problems.

In the end, both root cause analysis and problem solving are valuable tools for problem-solving and decision-making in the field of planning and activities. By prioritizing continuous improvement and data-driven decision-making, organizations can improve their processes, outcomes, and customer satisfaction, and stay competitive in a rapidly changing business environment.

Root Cause Analysis vs. Shallow Cause Analysis: What’s the Difference?

By Bob Latino

Updated: May 25, 2023

Reading Time: < 1 minute

Does regulatory compliance with RCA guidelines ensure operational reliability? Operational Reliability involves the aggregation of Equipment, Process and Human Reliability methods and techniques. What is the difference between troubleshooting, problem solving and root cause analysis? Are the outcomes different when we use The 5-Whys, The Fishbone or a Logic Tree? Can deficiencies in our approach to RCA increase the risk of excessive downtime?

These questions will be discussed in depth and contrasted using a common example to determine if we are using Root Cause Analysis or Shallow Cause Analysis.

Root Cause Analysis, Ishikawa Diagrams and the 5 Whys

Published: June 11, 2018 by Matthew Barsalou

Root cause analysis (RCA) is a way of identifying the underlying source of a process or product failure so that the right solution can be identified. RCA can progress more quickly and effectively by pairing an Ishikawa diagram with the scientific method in the form of the well-known plan-do-check-act (PDCA) cycle to empirically investigate the failure. Often, failure investigations begin with brainstorming possible causes and listing them in an Ishikawa diagram. This is not necessarily wrong, but often the ideas listed do not clearly contribute to the failure under investigation.

Write a Problem Statement

Once a problem-solving team has been formed, the first step in an RCA is to create a problem statement. Although critical for starting an RCA, the problem statement is often overlooked, too simple or not well thought out. The problem statement should include all of the factual details available at the start of the investigation including:

• What product failed
• The failure observations
• The number of failed units
• The customer’s description of the failure

The customer’s description does not need to be correct; it should reflect the customer’s words and be clear that it is a quote and not an observation. For example, a problem statement may start as, “Customer X reports Product A does not work.” The rest of the problem statement would then clarify what “does not work” means in technical terms based upon the available data or evidence. A good problem statement would be: “Customer X reports 2 shafts with part numbers 54635v4 found in customer’s assembly department with length 14.5 +/-2 mm measuring 14.12 mm and 14.11 mm.”

Create an Ishikawa Diagram

An Ishikawa (or fishbone ) diagram should be created once the problem statement is written and data has been collected. An Ishikawa diagram should be viewed as a graphical depiction of hypotheses that could explain the failure under investigation. It serves to quickly communicate these hypotheses to team members, customers and management. Hypotheses that have been investigated can also be marked on the Ishikawa diagram to quickly show that they are not the cause of the failure (Figure 1).

How Did the Failure Happen?

Elements in the Ishikawa diagram should be able to explain how the failure happened. For example, “lighting” is a typical example under “environment”; however, it is seldom clear how lighting could lead to the failure. Instead, the result of bad lighting should be listed and then empirically investigated. In this example, lighting could cause an employee to make a mistake resulting in a part not properly installed. Therefore, the part not properly installed would be listed in the Ishikawa diagram. Simply investigating the lighting could take time and resources away from the investigation so the first step would be to see if a part is installed.

Causes of a part not being installed can be listed as sub-branches, but the priority should be on determining if the part was installed or not. If a part is not correctly installed, then use the 5 Whys on that part of the Ishikawa diagram for investigation. The lighting may be a contributing cause, but it should not be the first one investigated. The Ishikawa diagram should be expanded each time 5 Whys is used. For example, the branch may end up as: material → part not installed → employee skipped operation → work environment too dark → poor lighting → light bulbs burned out.

In this example, the use of 5 Whys led to the true cause of the failure – the light bulbs burned out. Had the 5 Whys not been used, then the employee may have been retrained, but the same employee or somebody else may have made the same or a different mistake due to the poor lighting. Each time a cause is identified, the 5 Whys should be used to dig deeper to find the true underling cause of the failure. Failing to use the 5 Whys risks a recurrence of the failure – the corrective action may only address symptoms of the failure.

Other Potential Causes

Potential causes that do not directly explain the failure, but theoretically could have caused it, can be listed in the Ishikawa. This ensures they will not be forgotten; however, better explanations should be prioritized for investigation. Tracking and monitoring investigation are related actions can be facilitated by copying the Ishikawa items into a spreadsheet such as the one shown in Figure 2.

Here, each hypothesis from the Ishikawa diagram is prioritized and the highest priority hypotheses are assigned actions, a person to carry them out and a due date. This makes it easier for the team leader to track actions and see the results of completed actions. Such a tracking list can also be used to communication the team’s progress to management and customers. New insights may be gained as the investigation progresses. For example, somebody checking the length of a part may have observed damage. This damage could then be entered into an updated Ishikawa diagram and then transferred to the tracking list.

The Scientific Method

The scientific method should be used when investigating the failure. According to biophysicist John R. Platt’s Strong Inference , the scientific method consists of:

• Devising alternative hypotheses
• Devising a crucial experiment (or several of them) with alternative possible outcomes, each of which will, as nearly is possible, exclude one or more of the hypotheses
• Carrying out the experiment so as to get a clean result
• Recycling the procedure, making sub-hypotheses or sequential hypotheses to refine the possibilities that remain and so on

Each item in the Ishikawa diagrams should be viewed as a hypothesis that could explain the cause of the failure under investigation. A good hypothesis should be simple, general, avoid making too many assumptions and should be able to make refutable predictions. A simpler hypothesis is more likely to be correct. In general, it is best to look for the cause closest to the problem and then work back from there using the 5 Whys. The ability to make predictions is essential for testing the hypothesis ; a hypothesis that can’t be tested should not be trusted as there is no way to be sure that it is correct. As Dutch psychologist and chess master Adriaan de Groot said, “Where prediction is impossible, there is no knowledge.”

Integrate the Scientific Method

The scientific method can be integrated into RCA by using cycles of PDCA . The planning phases consist of describing the problem, collecting data and forming a hypothesis.

• P : Whether freshly formed or taken from an Ishikawa diagram, the hypothesis should make some form of prediction (or plan ), such as “measurement deviation” predicting “parts will be measured out of specification.”
• D : The next step is do – where the hypothesis is evaluated. This could be as simple as measuring a part or as elaborate as designing a new type of test method.
• C : The check phase is where the results are evaluated and conclusions are formed.
• A : Act is where the conclusions are acted upon. A hypothesis may be rejected or modified based on new evidence or the results of the testing, or a plan may be created to confirm a supported hypothesis.

If the hypothesis is not supported, then the next one in the prioritized tracking list should be selected and evaluated.

Using Ishikawa diagrams and the scientific method can serve as a standalone methodology for RCA or be used as part of any RCA process that uses Ishikawa diagrams. This approach is completely compatible with methodologies such as 8D and A3 reports.

What Is Root Cause Analysis? | Definition & Examples

Published on 7 January 2023 by Tegan George . Revised on 17 November 2023.

Root cause analysis is a problem-solving approach that uses the analogy of roots and blooms to model cause-and-effect relationships. Rather than focusing on what’s above the surface, root cause analysis troubleshoots solutions to problems by analysing what is causing them.

Root cause analysis is a form of quality management, often used in organisational management, quality control, and in healthcare fields like nursing. Root cause analysis can be a helpful study tool for students, too, when used for brainstorming or memorisation exercises.

It’s easy to draw root cause analysis charts by hand, on a whiteboard or a big piece of paper. Many people use fishbone diagrams as well, or you can download our template below.

Prevent plagiarism, run a free check.

One of the most common ways to conduct root cause analysis is using the ‘5 Whys’ method, popular in lean management. The 5 Whys are an interconnected method of analysis: after defining your problem, you ask ‘why?’  and answer as concisely as possible. The first ‘why’ often leads to the second, which leads to the third, etc.

In short, you continue to ask ‘why’ until the answer provided is no longer a contributor to the broader issue, but a possible solution to that issue. In other words, as you strategise, you’ll sense it’s time to stop when a provided answer has the potential to stop the whole problem from occurring, rather than only one aspect of that problem. This often takes 3-5 ‘whys’ but can definitely stretch out for longer.

You can use this template to map out your whys.

Root cause analysis is a great way to organise your thoughts, but its simplicity leads to a few downsides.

• Great brainstorming tool for individual or group projects.
• Can help identify causal relationships and clarify relationships between variables .
• ‘5 whys’ system can help simplify complex issues and drive possible solutions.

Disadvantages

• Can be overly simplistic, not leaving much room for nuance or variations.
• Path dependence can occur if the wrong question is asked, leading to incorrect conclusions.
• Cannot provide answers, only suggestions, so best used in the exploratory research phase .

There are several common tools used for root cause analysis , the most popular of which include fishbone diagrams , scatterplots, and the ‘5 whys’.

A fishbone diagram is a method that can be used to conduct root cause analysis.

Root Cause Analysis

Tracing a problem to its origins.

In medicine, it's easy to understand the difference between treating the symptoms and curing the condition. A broken wrist, for example, really hurts! But painkillers will only take away the symptoms; you'll need a different treatment to help your bones heal properly.

But what do you do when you have a problem at work? Do you jump straight in and treat the symptoms, or do you stop to consider whether there's actually a deeper problem that needs your attention? If you only fix the symptoms – what you see on the surface – the problem will almost certainly return, and need fixing over and over again.

However, if you look deeper to figure out what's causing the problem, you can fix the underlying systems and processes so that it goes away for good.

What Is Root Cause Analysis?

Root Cause Analysis (RCA) is a popular and often-used technique that helps people answer the question of why the problem occurred in the first place. It seeks to identify the origin of a problem using a specific set of steps, with associated tools, to find the primary cause of the problem, so that you can:

• Determine what happened.
• Determine why it happened.
• Figure out what to do to reduce the likelihood that it will happen again.

RCA assumes that systems and events are interrelated. An action in one area triggers an action in another, and another, and so on. By tracing back these actions, you can discover where the problem started and how it grew into the symptom you're now facing.

You'll usually find three basic types of cause:

• Physical causes – Tangible, material items failed in some way (for example, a car's brakes stopped working).
• Human causes – People did something wrong, or did not do something that was needed. Human causes typically lead to physical causes (for example, no one filled the brake fluid, which led to the brakes failing).
• Organizational causes – A system, process, or policy that people use to make decisions or do their work is faulty (for example, no one person was responsible for vehicle maintenance, and everyone assumed someone else had filled the brake fluid).

RCA looks at all three types of causes. It involves investigating the patterns of negative effects, finding hidden flaws in the system, and discovering specific actions that contributed to the problem. This often means that RCA reveals more than one root cause.

You can apply RCA to almost any situation. Determining how far to go in your investigation requires good judgment and common sense. Theoretically, you could continue to trace the root causes back to the Stone Age, but the effort would serve no useful purpose. Be careful to understand when you've found a significant cause that can, in fact, be changed.

The Root Cause Analysis Process

RCA has five identifiable steps.

Step One: Define the Problem

• What do you see happening?
• What are the specific symptoms?

Step Two: Collect Data

• What proof do you have that the problem exists?
• How long has the problem existed?
• What is the impact of the problem?

You need to analyze a situation fully before you can move on to look at factors that contributed to the problem. To maximize the effectiveness of your RCA, get together everyone – experts and front line staff – who understands the situation. People who are most familiar with the problem can help lead you to a better understanding of the issues.

A helpful tool at this stage is CATWOE   . With this process, you look at the same situation from different perspectives: the Customers, the people (Actors) who implement the solutions, the Transformation process that's affected, the World view, the process Owner, and Environmental constraints.

Step Three: Identify Possible Causal Factors

• What sequence of events leads to the problem?
• What conditions allow the problem to occur?
• What other problems surround the occurrence of the central problem?

During this stage, identify as many causal factors as possible. Too often, people identify one or two factors and then stop, but that's not sufficient. With RCA, you don't want to simply treat the most obvious causes – you want to dig deeper.

Use these tools to help identify causal factors:

• Appreciation   – Use the facts and ask "So what?" to determine all the possible consequences of a fact.
• 5 Whys   – Ask "Why?" until you get to the root of the problem.
• Drill Down   – Break down a problem into small, detailed parts to better understand the big picture.
• Cause and Effect Diagrams   – Create a chart of all of the possible causal factors, to see where the trouble may have begun.

Step Four: Identify the Root Cause(s)

• Why does the causal factor exist?
• What is the real reason the problem occurred?

Use the same tools you used to identify the causal factors (in Step Three) to look at the roots of each factor. These tools are designed to encourage you to dig deeper at each level of cause and effect.

Step Five: Recommend and Implement Solutions

• What can you do to prevent the problem from happening again?
• How will the solution be implemented?
• Who will be responsible for it?
• What are the risks of implementing the solution?

Analyze your cause-and-effect process, and identify the changes needed for various systems. It's also important that you plan ahead to predict the effects of your solution. This way, you can spot potential failures before they happen.

One way of doing this is to use Failure Mode and Effects Analysis   (FMEA). This tool builds on the idea of risk analysis to identify points where a solution could fail. FMEA is also a great system to implement across your organization; the more systems and processes that use FMEA at the start, the less likely you are to have problems that need RCA in the future.

Impact Analysis   is another useful tool here. This helps you explore possible positive and negative consequences of a change on different parts of a system or organization.

Another great strategy to adopt is Kaizen   , or continuous improvement. This is the idea that continual small changes create better systems overall. Kaizen also emphasizes that the people closest to a process should identify places for improvement. Again, with Kaizen alive and well in your company, the root causes of problems can be identified and resolved quickly and effectively.

Root Cause Analysis is a useful process for understanding and solving a problem.

Figure out what negative events are occurring. Then, look at the complex systems around those problems, and identify key points of failure. Finally, determine solutions to address those key points, or root causes.

You can use many tools to support your RCA process. Cause and Effect Diagrams   and 5 Whys   are integral to the process itself, while FMEA   and Kaizen   help minimize the need for RCA in the future.

As an analytical tool, RCA is an essential way to perform a comprehensive, system-wide review of significant problems as well as the events and factors leading to them.

What is Causal Analysis?  

Causal Analysis, or cause-and-effect analysis, is a systematic approach to understanding the relationships between causes and effects. It involves investigating and identifying factors contributing to a particular outcome or problem. This analysis aims to uncover the underlying causes that lead to a specific event or result. 

This method focuses on examining the connections and relationships between various factors to determine their influence on the outcome. Furthermore, it goes beyond surface-level observations and seeks to understand the root causes that drive a specific occurrence. 

What is Root Cause Analysis?  

Root Cause Analysis (RCA) is a systematic process used to identify the primary cause(s) of a problem or issue. It goes beyond the immediate or surface-level causes and delves deeper to find the underlying issues that contribute to the occurrence of a problem. 

In RCA, the focus is on investigating the primary cause or causes responsible for the problem. It aims to uncover the core issues that give rise to a particular problem rather than addressing only the symptoms or superficial aspects. 

This analysis technique is widely used in industries such as quality management, manufacturing processes, and safety investigations. It is particularly valuable when dealing with recurring problems or issues that require permanent solutions. 

By understanding and addressing the underlying causes, individuals and organisations can achieve long-term improvements and enhance their processes and outcomes.

Causal Analysis vs Root Cause Analysis – Key differences  

1. Scope and focus  

Causal Analysis focuses on understanding the cause-and-effect relationships between different factors and outcomes. It aims to establish connections and identify the reasons behind a specific event or result. 

On the other hand, Root Cause Analysis is more concerned with finding the primary or underlying cause of a problem. It goes beyond immediate or surface-level causes and delves deeper to find the underlying issues that contribute to the occurrence of a problem. 

Causal Analysis provides a broader perspective by examining multiple causes and their relationships. It considers various factors that contribute to a specific outcome. 

In contrast, Root Cause Analysis digs deeper and aims to identify the main cause that triggers a series of events. It focuses on finding the core issues that give rise to a particular problem. 

Take your ITIL skills to the next level with our comprehensive ITIL® Certification Training .  

3. Timeframe consideration  

Causal analysis often focuses on immediate or short-term causes, considering factors directly leading to an outcome.  

While Root Cause Analysis takes a more comprehensive and long-term view, it looks at the underlying factors that may have been present for an extended period and influenced the occurrence of a problem. 

4. Application areas  

Cau sal Analysis is commonly used in fields such as social sciences, economics, and business management. It helps to understand the relationships between variables and predict potential outcomes. 

Root Cause Analysis is frequently employed in quality management, manufacturing processes, and safety investigations. It is particularly useful when dealing with recurring problems and seeking permanent solutions. 

Conclusion  

C ausal Analysis vs Root Cause Analysis provides distinct perspectives on examining causes, with the former exploring relationships and the latter delving into underlying issues. By understanding the differences between the two, organisations can make informed decisions based on the nature of the problem and the desired outcomes.

Problem analysis & Root Cause analysis | Free BA Guide

These 2 types of analysis raise doubts in many business analysts .

Aren’t Problem analysis and Root Cause analysis quite identical?

Don’t we use root cause analysis when solving problems?

Then what’s the difference between them?

1.  Problem Analysis

Let’s first understand Problem analysis.

Problem analysis deals with understanding the problem in details.

How big is the problem?

What is the impact on company/unit performance?

When does it happen?

Whom does it affect?

Is it worth solving the problem?

Why does it happen?

The last question actually pertains to root cause analysis. We need to carry out root cause analysis when the magnitude of the problem is significant.

The technique to carry out Problem Analysis: 5W1H

5W1H is shorthand for “Who, What, When, Where, Why, and How.” It is used both in problem-solving and project planning.

This set of questions is sometimes referred to as the Kipling Method, due to a poem that appeared in Rudyard Kipling’s 1902 “Just So Stories.”

I keep six honest serving-men

(They taught me all I knew);

Their names are What and Why and When

And How and Where and Who.

When using 5W1H for problem analysis, if we address each of the W’s and the H, we will have a better understanding of the issue.

2.  Root cause analysis

Root cause analysis (RCA) is a structured examination of any aspect of a situation to establish the root cause. Two popular techniques for RCA are Fish-bone diagram and Five-whys.

Fish-bone diagram

Fishbone diagrams (also known as Ishikawa or Cause-and-effect diagram) are used to identify and organize possible causes of a problem. Fishbone diagram helps to focus on the cause of the problem versus the solution and organizes ideas for further analysis.

Steps to develop a cause-and-effect diagram:

Capture the issue or problem in a box at the right end of the diagram.

Draw a line from the box across the paper or whiteboard (forming the spine of the fishbone).

Draw diagonal lines from the spine representing major categories of potential causes (people, process, techniques, and policies).

Draw smaller lines to represent deeper causes on each major cause.

Brainstorm categories, and potential causes of the problem, and capture them under the appropriate categories.

Analyze the results. Remember that the group has identified only potential causes of the problem. Further analysis is needed to validate the actual cause, ideally with data.

Brainstorm potential solutions once the actual cause has been identified.

Five-whys is a question-asking process to explore the cause of a problem. Five-whys approach repeatedly asks questions in an attempt to get to the root cause of the problem.

This is one of the simplest facilitation techniques to use when problems have a human interaction component.

Steps to use:

Write the problem on a flip chart or whiteboard.

Ask “Why do you think this problem occurs?”, and capture the idea below the problem.

Ask “Why?” again, and capture that idea below the first idea.

Continue with step 3 until you are convinced the actual root cause has been identified.

Five-whys may take more or less than five times of asking why. The technique is called five-whys because often it takes that many whys to reach the root cause, not because it must be asked five times. Five-whys can be used alone or as part of the fishbone diagram technique. Once all ideas are captured in the diagram, use five-whys approach to drill down to the root causes.

Example 5-Why Analysis

Problem: Our server response time is more than the specified time.

Cause Level 1. The server hardware is slow.

Cause Level 2. Server hardware is slow as it does not have adequate RAM.

Cause Level 3. RAMs are expensive.

Cause Level 4. Adequate budget not approved for RAM.

Hope this article clarifies the similarities and differences between problem analysis and root cause analysis. We welcome suggestions and feedback to improve the discussion.
