Part 1 The DMAIC methodology

Six Sigma is an approach developed for businesses and organizations seeking to gain a competitive advantage. Six Sigma practices are designed to be instrumental in:

- driving process improvement and making statistically based decisions,

- measuring business results with a level of reliance,

- provisioning for uncertainty and error,

- combining high returns and benefits in the short, medium and long run, and

- removing the waste from any process.

The sigma score (written Zvalue) is an indicator of process quality that expresses process performance in terms of an ability to provide a product or a service that meets customer and third party specifications and expectations. It is directly related to either

a) the proportion of good or positive outputs (yield) provided by a process, or

b) the proportion of poor or negative outputs [%, ppm or defects per million opportunities (DPMO)] from a process.
