thank you for
your answer mr fredy
The5-Why analysis method is used to move past symptoms and understand the true root cause of a problem.
It is said that only by asking "Why?" five times, successively, can you delve into a problem deeply enough to understand the ultimate root cause. By the time you get to the4th or5th why, you will likely be looking squarely at management practices.
I think that you mean the "5 whys". The 5 Whys is an iterative question-asking technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem. (The "5" in the name derives from an empirical observation on the number of iterations typically required to resolve the problem.)
