When you want to solve any problem and want to eliminate the cause of the problem completely, you need strong problem solving tool such as 8d problem solving. And to analyze the root cause of the problem, you need something called 5 why analysis root cause tool that helps to find the most pin pointed root cause, so that you can take the necessary action to eliminate the problem permanently.
Along with 8D analysis tool, the A3 report is also considered to be one of the best problem solving tools of all time, which is now being used by many industries as both helps to effectively solve the problem. The 5 why analysis is the one that sits in the heart of both the problem solving tools, wherein you can identify the root cause and eliminate.
It all starts with a simple question, you know the problem, but you don’t know how to solve it? No matter how big or how small is your problem, the 5 why analysis tool helps to solve your problem effectively by allowing you to easily identify various causes so that you can eliminate the same.
There is no time or date for the problem to occur, it can suddenly happen or arise at any time in any process of your company or business. The problems are bound occur, especially when you think of boosting your business. Most of the problems are symptoms of very deeper issues, which can create a chaos on a later stage without your knowledge.
But you may ask us, how can it be so when you can easily and quickly fix the problem with a simple solution. Well, yes you will provide the solution, but is it a temporary fix or a permanent fix? Obviously, its a temporary fix and problem will arise again and again in the same way or in other different form when you are not fixing it permanently. That’s why you need a root cause analysis tool that helps you to solve the problem permanently and effectively. One such tool is the 5 why analysis root cause identification tool.

What is 5 Why Analysis Root Cause?
Definition of 5 Whys:
The 5 way technique is one of the most effective and most preferred root cause analysis tools in the world of problem solving, TQM, Lean Management, Six Sigma and so on. The 5 why tool effectively helps you to solve difficult of problems to the root by fixing all the causes with proper permanent corrective action that helps in preventing failures and mistakes recurring in future.
The five whys (5 whys) is a problem-solving tool or method that effectively solves a problem by making use of cause-and-effect diagram. The main goal of 5 whys is to find the root cause of a problem or a defect, by successfully asking the question why at-least 5 times in succession for every answer.
Origin of 5 Whys Analysis Tool And Why You Should Use 5 Why Technique?
All of us have already heard about Toyota. The origin of 5 Why analysis tool is happened in Toyota only. In the era of Japanese industry revolution, guy named Sakichi Toyoda, a Japanese inventor and industrialist has developed the five whys analysis tool as part of Toyota Production System (TPS), which is now used by many industries and is considered to be the best lean management tool for root cause analysis.
The Toyota has made it mandatory to ask Why five times whenever there is a problem. For every problem, one must respond with 5 whys until the final root cause is found. This helped Toyota to solve every problem including the most complex ones effectively and efficiently. Once the root cause is found, the Toyota was able to take the necessary permanent corrective actions to irradiate the problem once and for all. This strategy of 5 whys helped in improve the production efficiency drastically.
The Toyota Production System was focused on the successful implementation of 5 why strategy, wherein the team was able to focus on the problem on shop floor rather than the problems on the desks or meeting rooms. With this the decision making of the team was drastically improved with a key focus on processes by understanding what actually is happening in the shop floor.
Thus, the 5 why root cause analysis must be conducted along with the CFT including all process owners and operators. The one who is working on the shop floor, knows better than the ones who is working on meeting rooms. Operators always have a practical experience and knowledge who can give you the actual insights including the most valuable inputs. If required the CFT should also visit the shop floor to analyze the problem practically.
How To Use 5 Why Analysis Tool?
Remember, the 5 why analysis must be conducted by CFT along with Operators too. The CFT must contain all the key stakeholders including Process Owners and Subject Matter Experts (SME’s) too. The more the team is experienced, the problem solving with 5 why analysis is going to be more effective.
The 5 Why tool helps you identify the gray areas or the hidden causes that are really playing the role in development of problem. Thus, the 5 whys will show you the actual source of the problem with which you can effectively implement the corrective actions.
Most of the times when you address a problem, you will often say that it is a human error. But when you actually dive deeper in the root cause analysis, you will come to know that, it is either a process error, system error or the technical error. Only by fixing these causes you can able to nullify the problem. If you just fix the human errors, its never going to solve the actual root problem.
How to use the 5 why analysis root cause:
The 5 why analysis root cause model follows the simple seven step process to find out the exact root cause of any problem. To use 5 whys follow the below steps.
1. Assemble a Team
Remember, the first step in using a 5 whys analysis is to assemble a team of subject matter experts (SME’s). The subject matter expertise can be also called as cross-functional team (CFT) or multi-disciplinary team.
The CFT team must contain all the key stakeholders or the process owners or the key users from all key functions, such as Quality, QMS, Production, Assembly, Project Management, Engineering, Purchase, Supply Chain, Logistics, Stores, Warehouse or Dispatch, and so on.
The team must contain a Champion who is the master in problem solving or in systems, such as from QMS. There should also be a Leader who is going to lead the 5 why analysis from starting to until the counter measures are in place and closed. Champion will ensure that he supports the team and leader with all kinds of tools, countermeasures and decision making.
Choosing a team that is relevant to the problem is very much important. If necessary, you can also involve Operators, Customers, and Suppliers as and when required to completely eliminate the problem.
2. Define the Problem
Defining the problem description is one of the important parts of five why analysis. A problem description is the one that helps you clearly identify the root cause through 5 why analysis. Hence, sit with a CFT team and write down a clear problem description that helps you step on to the process of why why analysis.
For example, a clear written problem description could be, “Team Flash isn’t meeting its response time targets” or “Software release team Arrow resulted in too many rollback failures”. A problem statement written like this will help you conduct why why analysis and eliminate the root cause easily.
3. Ask the First “Why”
The process of 5 why why analysis starts with asking the first why. For this a leader of CFT can ask the team why the problem has occurred? or why the problem is occurring? For example, the leader can ask, “why isn’t team Flash meeting its response time targets?”.
You may think, asking why sounds very simple, but on a serious note answering the why takes a serious thought. The intention here is to find out the answers that are hidden under beneath the ground that have actually happened that are held responsible and accountable. These answers are the ones that cause the actual problem. Make sure that there aren’t any guesses, such as could have happened, might have happened, and so on.
By doing this way you can able to identify multiple causes of a problem that may create the problem again. To find out such multiple causes you can use, fish bone diagram, that allows you to get down to the multiple causes around 6M’s (Man, Machine, Method, Material, Measurement, and Mother Nature).
4. Ask “Why” 4 More Times
For each of the answers that are generated from the first why, must be further asked with whys at-least 4 more times in succession, so that you can get down to the bottom of the root cause. For every answer, frame another question in response for the answer that you have received.
A question followed by an answer will allow you to get down to the bottom of root cause. If there are multiple causes then ask whys for each one of them at-least 4 times in a row, until you get down to the bottom of the root cause until there are no further answers.
5. Know When to “Stop”
Another important factor that must be considered when you are conducting why why analysis is that, know when to stop asking why. In simple terms, you need to stop asking why when there are no more whys are not left, no useful responses are produced, and cannot go any further. Generally, a why why analysis ends at 5 whys. Sometimes this can go up to 6 whys.
6. Address the Root Cause
Once you have found the root cause, its time to lay down a corrective action or counter-measure followed by a permanent corrective action. Additionally, you can also implement horizontal deployment along with counter-measures for other whys too. Knowing when to stop asking why will allow you to find the perfect root cause to eliminate the problem.
7. Monitor Effectiveness
Once you have completed the 5 why analysis and implemented corrective actions along with horizontal deployment actions, now its time to measure and monitor the effectiveness of corrective actions. The effectiveness must be monitored at-least for 3 months or for 3 dispatches or as per customer requirements and the severity of the problem.
To measure the effectiveness you can use the effectiveness monitoring template and must be measured by CFT or the process owners on a inter-changed departments. You can also conduct layered process audits to measure the effectiveness of implemented actions.
When To Use 5 Why Analysis?
The 5 why analysis can be used anywhere you want where you see a problem and want to solve a problem. It can be used in any type of businesses and industries such as, Automotive, IT Software, IT Services, Healthcare, Aviation, Banking, Agriculture, Military, Space, Telecommunication, Manufacturing, Electronics, and so on. Hence, use 5 whys analysis for,
- Problem solving
- Troubleshooting
- Quality management
- Complex problems
- Simple problems
- In your own life and so on.
However, when the problem is more complex and there are chances of multiple causes, then you need to conduct 5 why analysis along with cause and effect diagram or a failure mode effective analysis (FMEA) to address multiple probable causes effectively. You can also use an is or is not sheet to get better results in writing down the problem and effectively solving the problem.
Factors to keep in mind while conducting 5 Whys Analysis
When you are conducting 5 why root cause analysis you must remember the following factors that impacts the 5 why problem-solving analysis. Treat these factors as the advice for why why analysis.
Advice to conduct 5 why analysis:
- A CFT must conduct the 5 why analysis
- All process owners and key stakeholders including operators must be involved for the 5 why analysis
- Management must be involved and engaged in the discussion of root cause and implementing counter-measures
- A 5 why analysis is not an individual responsibility. The responsibility of conducting a 5 why analysis lies with CFT
- Try to use whiteboards or printed 5 why analysis format rather than computers for better results
- During why why analysis everyone must share their ideas for continual improvements
- A problem statement must be written very clearly and do not just get carried away. The problem must be understood by every member of CFT including operator
- Use cause and effect diagram for better results
- Make sure that you distinguish causes from symptoms
- Always pat attention to the logic of cause and effect diagram relationship
- Never blame the root cause as human error or an operator error
- Root cause must be solved systematically to eliminate the problem completely
- The answers against 5 whys must be more precise and sensible
- Never jump to root cause directly or make conclusions without any base
- The statements made must be based on brainstorm, knowledge, facts, and analysis
- Conduct the 5 why analysis step-by-step and not to rush
- The root cause must be targeted to the process and not the people
- Brainstorm, be sincere, share ideas, and trust each other
- Know exactly when to stop asking why, meaning when the answer for why has no more sense
57 Examples of 5 Why Analysis
The ultimate aim of 5 why analysis is to get to the root of the problem and then fit the problem based on the root cause identified. A root cause can be of two types, one being the detection root cause and the other being the occurrence root cause. The five why analysis allows you to go down to the bottom of problem which could be actually an unexpected problem.
A problem can be of anything. Basically, in businesses the problems are divided into a human problem or human error, process problem, product problem, and a system problem. You must always focus on to solving a problem systematically followed by other types of problems. Hence, it is very important eliminate the root cause systematically in order to not to repeat such problems in future.
Here are few of the examples of five why analysis that you can go through to have better understanding.
