Fixing Special Causes is NOT Improvement

I have noticed that many Quality Improvement teams focus on special causes, not common causes. That’s not Quality Improvement. Here’s why:



“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].

“I was out working with one brewery, and they brought me into where the team was, and the team talked about all their little projects and everything else, but guess what? They were all doing special cause analysis.

“Workarounds are anti-improvement, focusing on nothing but special causes. That’s not improvement, that’s just dealing with day-to-day chaos. Improvement is when you start to reduce defects and errors, or increase patient satisfaction, or do something else.

I’m here on Ka’anapali Beach in Maui taking a little vacation, but I was thinking about this: “I’ve talked to a lot of people and they seem to think that that they have all these meetings where they fix special causes and they think they’re doing Quality Improvement. They’re not. If you’re just fixing special causes, that’s part of the Fix-It Factory. You want to become part of the Prevention Factory.
