Measuring Six Sigma Success

This recent article talks about how GE measured Six Sigma success:

“Engineers and scientists were measured on how many Six Sigma projects they completed during the year.”

Since I know that 4% of the business is causing over half of the waste, rework and lost profit (the 4-50 rule), making everyone do “Six Sigma projects” is a form of overproduction (violating a Lean rule). It creates waste, rework and unhappy employees. It makes people put trivial improvements in Six Sigma format to achieve the goals.

Measure Six Sigma success by bottom-line, profit and productivity enhancing results, not projects. Use data to focus improvements to maximize results and minimize effort. Don’t involve anyone that doesn’t need to be involved.
