- Design for Six Sigma
By systematically applying these steps, with the appropriate tools, practitioners of this approach have been able to save substantial dollars.
The basis of Six Sigma is measuring a process in terms of defects. The statistical concept of Six Sigma means your processes are working nearly perfectly, delivering only 3.4 defects per million opportunities (DPMO). Most organizations in the United States are operating at a 3-4 sigma quality level. This means they could be losing up to 25% of their total revenue due to processes that deliver too many defects, defects that take up time and effort to repair as well as making customers unhappy.
