Six Sigma

Six Sigma is a process improvement strategy that improves Output quality by reducing Defects.

Six Sigma is named after a statistical concept where a process only produces 3.4 defects per million opportunities (DPMO). Six Sigma can therefore be also thought of as a goal, where processes not only encounter less defects, but do so consistently (low variability).
