Unlocking the true potential of any process or problem often lies in the simple act of asking why. In the fast-paced world we live in, it’s easy to get caught up in the rush of finding quick solutions without fully understanding the underlying causes. That’s where the art of conducting a successful why why analysis comes into play. By delving deeper into the root causes of an issue, you can uncover valuable insights and make informed decisions that lead to impactful changes. In this article, we will explore the power of asking why and how to conduct a why-why analysis effectively.
Why Why Analysis is where your search for one of the simplest and effective problem solving methods ends. Widely used in the world of lean development, this method also known as the 5 Why Analysis, cuts through false alarms and leads you to the root cause of a problem.
The Why Why Analysis involves asking why five times in a row to get to the root cause of an issue. This simple yet effective analytical process can be used in both personal and professional settings.
In a previous blog post, we discussed how to use the 5 whys analysis as an effective way to drill down to the root cause of a problem.
The reason it is so powerful is that it allows you to ask why until you reach a basic, fundamental reason for the problem. Once you have uncovered the root cause, you can then work on fixing it. In this blog post, we will discuss 5 reasons why you should perform a why why analysis.
What is a Why Why Analysis?
The Why Why Analysis is a problem-solving strategy that helps you break down complex problems into smaller, more manageable pieces. It was developed by Toyota Motor Corporation in the 1970s as a way to improve its manufacturing process.
“The basis of Toyota’s scientific approach is to ask why five times whenever we find a problem … By repeating why five times, the nature of the problem as well as its solution becomes clear.” – Taiichi OhnoTweet
The Why Why Analysis works by asking “why” five times in a row. Each time, you drill down further into the problem until you reach the root cause. This technique can be used to solve all sorts of problems, from manufacturing defects to customer service issues.
Also known as the “5 Why Analysis”, it uncovers the root causes of problems or issues.
Whether you’re a business owner looking to improve efficiency, a project manager seeking to troubleshoot problems, or simply someone who wants to enhance their problem-solving skills, mastering the art of asking why is a skill that can set you apart from the rest. Join us as we delve into the fascinating world of why-why analysis and discover how it can transform the way you approach challenges.
How to perform a why why analysis?
The 5 Why analysis involves asking the question “why” repeatedly until you reach a root cause. This technique can be used in business, engineering, and product development contexts.
The why why analysis is a great way to troubleshoot problems because it helps you to identify the root cause of the issue. Once you know the root cause, you can take steps to address it. The technique is also helpful for understanding how products and services work.
The steps of a Why Why analysis are:
- Define the problem
- Ask why the problem occurred
- Ask why each answer to the previous question occurred
- Repeat until you reach a root cause
- Create a plan to solve the problem
What is a problem? Define the problem
A problem is an unwanted or unpleasant situation that needs to be fixed. Problems can arise from many different things, such as a malfunctioning product, a customer service issue, or a natural disaster.
When something goes wrong, it’s important to identify and solve the problem as quickly as possible. This can be difficult, especially if the problem is complex or there are multiple issues to deal with. However, by taking the time to understand the problem and come up with a plan to fix it, you can minimize the damage and keep your customers happy.
The first step is to determine what the problem is. This may seem like a simple task, but it can be surprisingly difficult to accurately identify the root cause of a problem. Be specific and concise in describing the issue at hand.
The Why Questions (Examples)
The “5 Why” analysis begins by asking “Why?” five times in succession until you reach the root cause of the problem. The following example will help illustrate how the “5 Why” analysis works.
Suppose you are a manager at a manufacturing company. One of your employees has been injured on the job. You ask him what happened and he tells you that he was using a power saw to cut some wood when the saw kicked back and hit his arm.
Then you ask him why the saw kicked back and he says that the blade was dull and he was not using a saw blade guard. Next question is why he was not using a saw blade guard and he says that it was not on the saw when he got it from the supply room.
Ask him next why the guard was not on the saw and he says that the last person who used the saw did not put it back on. Finally you ask him why the last person did not put it back on and he says that she did not think it was necessary because she did not damage the blade.
At this point, you have reached the root cause of the problem: The employee was injured because the last person who used the saw did not put the blade guard back on, causing the current employee to use a dull blade without protection.
The “5 Why” analysis is a simple but effective tool that can help you identify root causes of problems so that you can take steps to prevent them from happening again. This analysis can be used in any situation where you need to identify the cause of a problem so that you can take corrective action.
The why why analysis is based on the premise that most problems have multiple causes and that each individual cause can have its own set of causes.
By repeatedly asking the question “why,” you can drill down to the root cause of a problem. This process is also sometimes referred to as a “cause and effect” analysis.
To use the why why analysis, simply ask the question “why” five times in succession. For each answer, ask the question again. Here’s an example:
Problem: The car won’t start.
- 1st why: Why won’t the car start? The battery is dead.
- 2nd why: Why is the battery dead? The alternator isn’t working.
- 3rd why: Why isn’t the alternator working? The alternator belt is broken.
- 4th why: Why is the alternator belt broken? The alternator belt was not replaced when the last tune-up was performed.
- 5th why: Why wasn’t the alternator belt replaced during the last tune-up? The mechanic did not notice that the alternator belt was worn during the last tune-up.
The solution here is reviewing and adding the missing steps in the SOP to be followed by the mechanic.
The Top 5 Reasons Why You Should Perform A Why Why Analysis
When it comes to problem solving, many people instinctively turn to brainstorming. However, this technique is often ineffective, as it can be difficult to come up with good solutions when you’re under pressure. A Why Why analysis is a more effective problem-solving strategy that can help you find creative solutions to complex problems.
Here are the five reasons why you should perform a Why Why Analysis:
The 5 Why analysis helps you to:

Understanding the importance of asking “Why”.
Asking “why” is a fundamental aspect of critical thinking and problem-solving. It allows us to challenge assumptions, identify gaps in our knowledge, and gain a deeper understanding of the situation at hand.
When we ask why, we open the door to a world of possibilities and opportunities for improvement. It is through this act of questioning that we can uncover the hidden factors that contribute to a problem and find innovative solutions.
Conducting a why why analysis involves a systematic approach to asking why multiple times to get to the root cause of an issue. This technique, popularized by the Toyota Production System, helps to uncover the underlying factors that contribute to a problem and allows for targeted problem-solving efforts.
By asking why repeatedly, we can peel back the layers and uncover the true cause rather than merely addressing the symptoms.
What Are the Benefits of Conducting a Why Why Analysis?
The benefits of conducting a why why analysis are numerous and far-reaching. Firstly, it allows for a more comprehensive understanding of the problem at hand. By going beyond surface-level observations, we can identify the underlying causes and address them directly.
This leads to more effective problem-solving and prevents the same issues from recurring in the future.
Secondly, a why why analysis promotes a culture of continuous improvement within an organization.
By encouraging employees to question the status quo and seek out the root causes of problems, organizations can foster a sense of ownership and empowerment. This, in turn, leads to increased efficiency, innovation, and overall success.
Lastly, conducting a why-why analysis enables data-driven decision making. By systematically collecting and analysing data, organizations can make informed choices based on evidence rather than intuition. This reduces the risk of making hasty decisions that may have unintended consequences.
What Are Some Common Challenges and How to Overcome Them in a Why-Why Analysis
While conducting a why why analysis can be highly beneficial, it is not without its challenges. Here are some common challenges that may arise and strategies to overcome them:
1. Limited data:
In some cases, it may be challenging to gather sufficient data to support the analysis. To overcome this, leverage existing data sources, conduct additional research, or consider implementing data collection mechanisms to ensure you have the necessary information.
2. Biased perspectives:
Different stakeholders may have different perspectives and biases that can influence the analysis. To mitigate this challenge, ensure a diverse group of individuals is involved in the analysis process. Encourage open and honest communication, and consider using facilitation techniques to ensure all voices are heard.
3. Lack of time and resources:
Conducting a thorough why-why analysis requires time and resources. To overcome this challenge, prioritize the most critical problems and allocate resources accordingly. Break down the analysis into manageable steps and set realistic timelines to ensure progress is made.
4. Resistance to change:
Implementing changes based on the findings of a why-why analysis may face resistance from individuals or teams. To address this challenge, involve key stakeholders early in the process and communicate the rationale behind the proposed changes.
Provide training and support to facilitate the transition and address any concerns that may arise.
By being aware of these challenges and proactively addressing them, you can ensure a smooth and successful why-why analysis.
Tools and Techniques to Use in a Why-Why Analysis
There are several tools and techniques that can enhance the effectiveness of a why-why analysis. Here are a few commonly used ones:
1. Five Whys: The Five Whys technique involves repeatedly asking why to uncover the root cause of a problem. By asking why at least five times, you can delve deeper into the underlying factors that contribute to the issue.
2. Fishbone Diagram: Also known as a cause-and-effect diagram, a fishbone diagram helps visually map out the various factors that contribute to a problem. It provides a structured approach to identifying potential causes and can uncover relationships that may not be immediately apparent.
3. Pareto Analysis: Pareto analysis involves identifying and prioritizing the most significant causes contributing to a problem. By focusing efforts on the vital few causes, you can maximize the impact of your problem-solving efforts.
4. Root Cause Analysis: Root cause analysis is a systematic approach to identifying the underlying cause of a problem. It involves gathering data, analyzing the causes, and determining the actions needed to prevent recurrence.
These tools and techniques can be used individually or in combination to conduct a thorough why-why analysis and uncover the root causes of a problem.
