The five whys is based on a misguided reuse of a strategy to understand why new features should be added to products, not a root cause analysis. To avoid these issues, Card suggested instead using other root cause analysis tools such as fishbone or lovebug diagrams .
For example, an "Is/Is Not" worksheet is a common tool employed at D2, and Ishikawa, or "fishbone," diagrams and "5-why analysis" are common tools employed at step D4. In the late 1990s, Ford developed a revised version of the 8D process that they call "Global 8D" (G8D), which is the current global standard for Ford and many other companies in ...
The example of a 5-whys analysis of a car not starting illustrates an almost perfect example of the 5-whys failing. First you need to ask the right questions - and in this case there are almost five whys for every 1 of the first five whys. The car won't run.

Sample Ishikawa diagram shows the causes contributing to problem. The defect, or the problem to be solved, [1] is shown as the fish's head, facing to the right, with the causes extending to the left as fishbones; the ribs branch off the backbone for major causes, with sub-branches for root-causes, to as many levels as required.
The basis of the technique is to ask "why" five times to identify the primary causal factor behind a particular issue. It is suitable for a range of problem complexities and is often used in conjunction with other root cause analysis tools, such as fishbone diagrams and cause-and-effect tables. Although it may seem simplistic, the 5 Whys can be ...
