Design for Six Sigma (DFSS), or the Six Sigma DMADV process (Define, Measure, Analyze, Design, Verify), is an improvement system used to develop new processes or products at Six Sigma quality levels. It also can be employed if a current process requires more than just incremental improvement. It is executed by Six Sigma Green Belts and Six Sigma Black Belts, and overseen by Six Sigma Master Black Belts.
