Answer: “My Daddy told me to never say ‘Y’ again and the ‘P’ went down my leg.”
Lately, I’ve been asked to provide root-cause analysis training more than ever before in my 14 years as an independent quality/lean consultant. This is interesting in the age of Six Sigma, especially because “analyze” is the heart of DMAIC (define, measure, analyze, improve, control). I further find this interesting in this age of lean, in which the lean tools that are taught to so many people are only possible solutions to good root-cause analysis. I (further) further find this interesting in this age of so many companies being ISO 9001-certified for many years, when the essence of continually improving the effectiveness of the quality management system is good root-cause analysis.
I began to wonder, “Why does root-cause analysis suck?,” and I came up with the following possible root causes. You decide which apply to your company by asking “Why?” somewhere around five times until you find the systemic reason(s) that it sucks at your company.
Drum roll, please. . . .
