Problems using 5-Whys? Read “Under Scrutiny” from Quality Progress to understand why!
Root Cause Analysis Under Scrutiny
Are your root cause analysis results “under scrutiny?” Do you have problems finding the root causes of quality problems, safety incidents, or mechanical failures? It could be because of the root cause analysis tools you use. Some tools have inherent weaknesses that are “built-in.” You will always have problems when faults are built-in to the tools you use.
The article (“Under Scrutiny” – used here by permission – reprinted from Quality Progress, the flagship magazine of the quality professional society ASQ), explains why some techniques commonly recommended for root cause analysis (like 5-Whys) will cause problems when applied to find root causes.

But there is even more wrong with the 5-Why example in the Quality Progress article.
First, you can read about the “debunking” of the article at this link (saved here because the original link went bad):

It seems that instead of asking 5-Whys, they spent over $2,000,000 finding causes of the monument’s problems.

What can you do to overcome the limitations inherent in 5-Whys? Stop being “under scrutiny” and try something new. Something built on a solid foundation of human factors and root cause analysis research.
Time to try something new…
