Six Sigma
Six Sigma is a business management strategy, initially implemented by Motorola. As of 2009 it enjoys widespread application in many sectors of industry, although its application is not without controversy.
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects and variability in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization (“Black Belts”, “Green Belts”, etc.) who are experts in these methods. 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).
