Many organizations that deploy Lean and Six Sigma eventually hit what is referred to as the “performance measurement wall.” These organizations begin with the right intentions, however, the bottom-line results from their Lean and Six Sigma initiatives are often illusionary because they are focused on the wrong targets. One of the major reasons for this […]

After a rocky start developing the project’s primary metric, a Six Sigma team was able to increase the accuracy rate of dispenser maintenance calls, resulting in potential savings for the company of more than a million dollars.

A key measurement of Six Sigma effectiveness is the application of appropriate metrics.
