Comments on: Not Just Asking Why? – Five Investigations http://theleanthinker.com/2008/10/21/not-just-asking-why-five-investigations/ Thoughts and insights from the shop floor.

Too many have interpreted 5 Whys as an activity that can be completed at a flipchart in 5 min. or less. Thanks for emphasizing that facts and critical thinking are the key to successful root cause analysis. Mark, brilliant stuff. 5 Whys should really be called 5 Investigations (not as catchy, I guess).

Too much literature out there identifies it as a way to "find the root cause" Thanks! Curt – you bring up the cause/effect diagram and point out the correct way to use it – to identify *possible* causes! Too much literature out there identifies it as a way to “find the root cause”

Thanks!

Using your analysis, each why is accompanied by systematic problem-solving approach. By using a cause and effect diagram at each "why", a team will consider all possibilities and either verify or eliminate identified causes before moving to the next "why". This prohibits the shotgun approach of jumping to the perceived solution too fast, and allows the team to highlight the root cause. Great points- 5 Why is usually over-simplified.
