Six Sigma

A movement, method, and set of techniques focused on improving the consistency of business processes. Relies heavily on statistical techniques to measure success. There are multiple Six Sigma methods, some designed for process improvement and some for designing or redesigning business processes. Most Six Sigma books, however, emphasize incremental process improvement with a major emphasis on reducing the variability in the quality or quantity of the output. Was originated at Motorola in the mid-Eighties by crossing quality control and traditional process redesign.
