Six Sigma is a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986. Jack Welch made it central to his business strategy at General Electric in 1995. Today, it is used in many industrial sectors. The concepts and methodologies of Six Sigma, stresses on the use of statistical tools and techniques for improving quality and reducing defects. It focuses on making consistent quality improvements to business processes until it is fully optimized. As a certain quality level is achieved, the organization shifts gears and starts concentrating on achieving other levels of quality. The whole process continues until all the business processes are fully optimized.
Six Sigma projects follow two project methodologies inspired by Deming's Plan-Do-Check-Act Cycle. These methodologies, composed of five phases each, bear the acronyms DMAIC and DMADV.
