Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process — from manufacturing to transactional and from product to service.

Six Sigma is a business management strategy, originally developed by Motorola in mid-1980s, Six Sigma is wide spread application in many sectors of industry.

The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV.

  • DMAIC is used to improve an existing business process.
  • DMADV is used to create new product or process designs.
