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” […]
