For some companies, quality issues account for up to 40% of operational costs. That’s like setting fire to nearly half your budget!
What if you could spot these problems early on?
Enter the 5 Whys technique—a problem-solving technique born in the halls of Toyota Motor Corporation.
In the 1930s, founder Sakichi Toyoda revolutionized their approach to persistent production issues. Instead of quick fixes, he championed a method of repeatedly asking “Why?”—five times, specifically—to get to the heart of each problem.
The 5 Whys method was later integrated into Six Sigma methodologies—a set of techniques that reduce defects and improve quality in production processes. Today, it is widely adopted across various industries, from automotive to healthcare.
With this guide on using 5 Whys, you’re all set to become your company’s in-house root cause analysis expert. Let’s get started!
How to use 5 Whys for Root Cause Analysis with Examples
Summarize this article for me pleaseUnderstanding the 5 Whys Method
In problem-solving, uncovering an issue’s underlying cause or root cause is essential for implementing effective and lasting solutions.
The 5 Whys technique offers a straightforward and powerful approach to examining problems. It involves repeatedly asking ‘Why?’ until the underlying cause is identified.
What is the 5 Whys method?
Five Whys (or 5 Whys) has been defined as an ‘iterative interrogative technique used to investigate the cause-and-effect dynamics that contribute to a specific issue.’
This technique is a five-step journey into the heart of a problem, a little like peeling an onion. By repeatedly asking “Why?” teams can peel back the layers of symptoms to uncover the underlying root cause.
The framework provides a structured approach to problem-solving where each answer becomes a stepping stone toward a deeper understanding that eventually uncovers the true source of the issue.
Importance of 5 Whys in root cause analysis and problem-solving
The 5 Whys technique plays a crucial role in root cause analysis (RCA) by enabling organizations to:
- Instill a culture of inquiry: It encourages teams to question existing processes and assumptions, leading to continuous improvement
- Identify underlying issues: It helps uncover hidden problems that might not be immediately apparent
- Refine processes: By addressing root causes, companies can improve their processes to prevent future issues
- Enhance decision-making: It promotes data-driven decision-making by basing solutions on fundamental causes rather than symptoms
- Improve project controls: It enhances project controls by uncovering the root causes of deviations, enabling more effective corrective actions

Implementing the 5 Whys methodology is straightforward and can yield powerful insights. Here’s a systematic step-by-step guide on how to implement the 5 Whys:
📌 Step 1: Define the problem: Clearly state the problem you want to solve. Be specific and avoid vague or generic descriptions.
📌 Step 2: Start asking why: Ask “why?” five times, building upon each answer to delve deeper into the root causes of the problem. Each “why” should lead to a more fundamental level of understanding.
📌 Step 3: Find the root cause of the issue: After asking “Why?” repeatedly, analyze the answers to identify the underlying cause of the problem. This may require further discussion and analysis.
📌 Step 4: Implement the solution: Develop and implement a solution that addresses the root cause of the problem. Ensure that the solution is effective and sustainable.
📌 Step 5: Evaluate the solution’s effectiveness and adjust as needed. This process will help resolve the problem, and the final solution will produce the desired results.
You can leverage powerful solutions to enhance your 5 Whys analysis process.
Let’s see an example of the 5 Whys methodology in action:
Problem statement: A patient received the wrong medication during their hospital stay.
Applying the 5 Whys methodology:
1. Why did the patient receive the wrong medication?
The nurse did not complete the patient identification process correctly.
2. Why did the nurse not complete the patient identification?
The patient did not have a wristband for identification.
3. Why did the patient not have a wristband?
The wristband had been removed for a procedure and was not replaced afterward.
4. Why was the wristband not replaced?
The staff was unaware it needed to be put back on after the procedure.
5. Why were they unaware of this requirement?
There was no established protocol or training regarding the replacement of wristbands after procedures.
Identification of root cause and solution implementation
The root cause identified through this process is the lack of a protocol for replacing wristbands post-procedure. To resolve this issue, the hospital can implement a standardized procedure for ensuring that all patients have their identification wristbands replaced immediately after any medical intervention.
You’ve now seen the 5 Whys in action. Is there a simple, straightforward way to adopt it in your organization?

Challenges of implementing the 5 Whys and overcoming them
While the 5 Whys is an effective tool, it is not without its challenges. Here are some common hurdles and strategies to overcome them:
Challenge 1: Stopping at symptoms instead of root causes
It’s easy to get caught in a loop of superficial solutions. Teams might think they’ve nailed the problem when they identify a symptom, but that’s often just the tip of the iceberg.Â
For instance, a customer service team might blame increased complaints on staffing shortages and hire more people. However, if the real issue is poor training, the problem will persist.
Solution: To avoid this trap, encourage your team to keep digging. Ask “Why?” repeatedly—even if you have to ask ‘why’ more than five times—until you unearth the root cause.
Challenge 2: Cognitive biases influencing the analysis
Our own biases can cloud our judgment. Preconceived notions can lead teams to overlook specific causes or jump to conclusions. For example, a manager who blames operators for equipment failures might miss underlying mechanical problems.Â
Solution: To avoid this bias trap, assemble a diverse team with different viewpoints. Back up your “Why?” answers with data and evidence. A study by Harvard Business Review found that diverse teams are 35% more effective at problem-solving because they bring a more comprehensive range of perspectives to the table.
Challenge 3: Failing to involve the right stakeholders
A successful root-cause analysis depends on having all the pieces of the puzzle. If you leave out key stakeholders with firsthand knowledge of the problem, you risk getting a distorted or incomplete picture.Â
For instance, analyzing a production issue without input from line workers might overlook crucial operational details.
Solution: Team members from all levels of the issue should be involved to ensure a comprehensive analysis. This will give you a more complete understanding of the problem. A report by McKinsey & Company found that projects involving cross-functional teams are 20% more successful.
Challenge 4: Stopping at a single root cause
Many problems are like tangled webs, often with more than one root cause. Teams might get excited when they find one underlying cause, but that doesn’t mean they’ve seen it all.Â
Solution: Exploring multiple causes and addressing multiple root causes is essential.
Challenge 5: Not documenting the learnings
Knowledge is power, but only if you keep track of it. Without proper documentation, valuable insights from your 5 Whys analysis can be forgotten. And if you don’t follow up on the solutions, you may have to deal with the same problem repeatedly.
Solution: Implement a systematic approach to documenting your 5 Whys analyses. Use ClickUp Docs to create a centralized repository, such as a wiki, for all your problem-solving efforts.

Problem statement: A car manufacturer notices an increase in defective vehicles.
1. Why are so many of our vehicles involved in traffic accidents this winter?
The number of brakes failing to function has increased.
2. Why are the brakes failing to function this winter?
Because the viscosity of the brake fluid becomes too high in cold weather, it leads to a slower response when applying brakes.
3. Why is the viscosity too high this winter?
Because we changed our brake fuel vendor this year, and the brake fluid we are now receiving tends to thicken in cold weather.
4. Why did we change our brake fuel vendor?
Because the vendor was offering brake fluid at a lower price.
5. Why was the brake fluid of this vendor cheaper?
Because it was meant for warmer countries and lacked anti-coagulant.
Root cause: Cost-cutting decision to change vendors without thoroughly vetting the new product’s suitability for all operating conditions.
Solution: (a) Return to the earlier brake fluid vendor, (b) double-check technical specs for new vendors, and (c) ensure the production head is consulted before changing material vendors.
Resolving software bugs
Problem statement: Bug reports related to the flagship application software are causing incident management issues at the client end due to frequent system crashes during user login.
1. Why does the application crash during login?
Because it throws a null pointer exception.

3. Why is the user object null?
Because the database query returns no result.
4. Why does the database query return no result?
Because the user table is corrupted.
5. Why is the user table corrupted?
Because of an unexpected shutdown during a database update.
Root cause: Lack of robust database management practices to handle unexpected shutdowns and ensure data integrity.
Solution: Establish proper backup procedures and ensure database integrity checks after unexpected shutdowns.
Team problem-solving
Problem statement: A team’s project is consistently behind schedule.
1. Why is the project behind schedule?
Because tasks are delayed.
2. Why are tasks delayed?
Because team members are missing deadlines this month.
3. Why are team members missing deadlines?
Because they’re unclear about priorities.
4. Why are they unclear about priorities?
Because this month, the frequency of communication from the project management office has decreased.
5. Why is there reduced communication?
Because the project manager is overloaded with administrative tasks related to the financial year-end.
Root cause: Inadequate resource allocation, leading to the project manager being overwhelmed with non-project-related tasks, affecting team communication and prioritization.
Solution: Reassign administrative tasks to others so the project manager can focus on team communication and prioritization. Develop a standardized meeting agenda template in ClickUp and provide training on effective meeting management. Implement best practices for effective meeting participation.
Case studies: Practical applications of the 5 Whys
