It includes identifying factors which are critical for the quality as determined by the customer. It reduces process variation and improvement capabilities, increases stability and designs systems to support the six sigma goal.

The word "Sigma" is a Greek sign used for a statistical term that measures how far a given process deviates from perfection (standards deviation "Two Six Sigma sub-methodologies are called DMAIC (Define, Measure, Analyze, Improve and Control), and DMADV (Define, Measure, Analyze, Design, Verify).

The first step in any Six Sigma project is to clarify the problem and narrow its scope in such a way that measurable goals can be achieved within a few months. Then a team is assembled to examine the process in detail, suggest improvements, and implement those recommendations. In the manufacturing world, project managers and their sponsors typically begin by defining what constitutes a defect and then establish a set of objectives designed to reduce the occurrence of such defects. Measurement . In the second step of a Six Sigma project, the team gathers data and prepares it for high-level analysis.

The team members usually start by identifying the ways in which people fail to act as needed, or by identifying the ways in which people fail to ensure effective control at each stage. Improvement . Recommend, decide and implement improvements. Control . In the final stage of a Six Sigma project, the team creates controls. These are enabling the company to sustain and extend the improvements
