Second root cause: There is an issue with the project management as ideally, a code freeze should happen at least 4 days before the UAT but here the team was working on fixing bugs at the last day.
Following are the key steps in the overall process of conducting a thorough 5 Whys analysis: When you are faced with a problem, the first logical step is to gather relevant team members.
Continuous implementation of practices like 5 Whys has made Toyota the world’s largest automaker.
One of the main reason why 5 Whys is so popular as a root cause analysis technique is its simplicity. There are no fancy steps no acronyms and there is no need for any memorization.
When faced with a lingering or reoccurring problem what do you do?
There are 2 solutions – Just try to resolve the problem and move on Or investigate and analyze to see what is the real source of the problem so that it does not resurface.The technique is suited for simple problem solving, but larger more complex issues should be handled with a more thorough technique although the 5 whys can initially be used to generate potential causes of some problems and to stimulate the thought process.In the following example of a production issue the 5 why problem solving technique is appropriate to use due to the most likely cause of the problem needs to be found quickly and is likely to not require a complex fault finding process.The 5 Whys problem solving technique uses a very simple iterative approach in analysing and attempting to find the root cause of a problem.The 5 why technique originates from the Toyota Manufacturing system pioneered in Japan by the Toyota car company.When an issue occurs with a manufacturing machine the solution is not found by looking at some historical data or manual.A deduction is made by understanding the problem, asking questions to people working there, inspecting and then making a decision.Once the most immediate cause has been identified for the first effect or symptom of a problem and written down, you repeat the process of asking why this is the case or this cause itself is caused by what?The process continues for five times or until the root cause has been reached, thus giving it the name 5 whys.5 Whys, is a proven and widely used technique for ‘Root Cause Analysis’ which helps identify the cause(s) contributing to the occurrence of the problem.This article takes you through the history of 5 Whys, its basics and examples, the correct procedure to conduct 5 Whys analysis and some tips & best practices on 5 Whys.
