DPMO Process Sigma Table

Defects per million opportunities (DPMO) is the number of defects in a sample divided by the total number of defect opportunities multiplied by 1 million. It is used for measuring the level of performance and gain of performance of a process. Use this DPMO Process Sigma table to find the equivalent process sigma metric and yield for a DPM.
