What is Six Sigma?

Six Sigma is a set of techniques and tools used for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986. Six Sigma seeks to improve the quality of the output of a process by identifying and reduce the causes of defects and minimizing variability in manufacturing and business processes. It uses a set of quality tools and creates a special infrastructure of people within the organization who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has specific value targets, for example: to reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction, and increase profits.
