Originally developed in 1986 by Motorola, the business management strategy is now used in many different industries in an effort to improve the quality of products or services produced by the business through the removal of defects and errors. The strategy involves creating groups of people within the business or organization who have expert status in various methods, and then each project is carried out according to a set of steps in an effort to reach specific financial milestones. A six sigma process is defined as one in which 99.99966% of products created are expected to be statistically free from defects. See also Lean Six Sigma.
