Six Sigma

Six Sigma is a process improvement strategy initially adopted in manufacturing. The name Six Sigma is based on a statistical quality measurement that indicates near zero defects. The foundational premise of Six Sigma is the idea that product defects can be removed by improving business processes and eliminating variability of the manufacturing process. Quality management methods that utilize statistical techniques characterize Six Sigma. Methods are so technical that they often require specially trained individuals to fully implement the ideas. Degrees of expertise in Six Sigma are identified by titles borrowed from the martial arts (e.g., Black Belts, Green Belts, etc.). Six Sigma projects follow a defined sequence of steps and have quantified targets.
