Six Sigma is a business management strategy originally developed by Motorola. In 2009 widely applied in various industrial sectors, though the application is not without controversy. Six Sigma aims to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes. Realized by using 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 made a calculation of the target. These targets can be financial (cost reduction or profit increase) or whatever is critical to the customer of the process (cycle time, safety, delivery, etc.).
