Six Sigma is a business management strategy, originally developed by Motorola, that today enjoys wide-spread application in many sectors of industry.

Six Sigma seeks to identify and remove the causes of defects and errors in manufacturing and business processes.[1] It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization (“Black Belts” etc.) who are experts in these methods.[1] Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase)

  1. Six Sigma is a business management strategy first developed by Motorola in 1986, used widely by many successful companies in a wide variety of industries. The core of Six Sigma is to seek improvement in the quality of process outputs by identifying and removing the causes of defects, and minimizing variability in business and manufacturing processes. The term comes from the notion that if “one” has six standard deviations between the process mean and nearest specification limits—practically no output will fail to meet specifications.
