5 why and fish bone both the techniques are used for RCA of problem and the result of both the techniques are the same. I want to know on what basis one should select one of the methods. Like whether it should be based on kind of problem description or just any one can be used for all problems.
5 why's and fishbone analysis are related. i mean, 5 why's can be a part of Fishbone analysis. It can used to analyze any kind of problems.
the only thing is ,for fishbone analysis its good if you have a brainstorm session, in order to get the right why's / causes for the problem, so that the problem can be prevented in future.[by taking preventive actions based on the root cause identified]
