This is more of a quality problem example rather than the typical Monday Accident article. It starts with an example of root cause analysis in an old video from the Juran Institute …

Now apply your analytical skills … Is this a good job or a bad job of root cause analysis?

Now read this article that I wrote for Quality Progress titled, Under Scrutiny, posted here:

You don’t need to be a member of ASQ to read the article, just register to see the open access article.

Now you can understand why I don’t think the 5-Whys helped them find root causes. Rather, all it did was help them explain the knowledge they already had.
