An Overview of the Six Sigma Process

Six Sigma is a business management strategy that seeks to identify and remove the causes of defects and errors 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' etc.) who are experts in these methods.

The Six Sigma DMAIC Process

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).
