What is Six Sigma?
 
 
There is not only one answer to what is Six Sigma. 
 
Firstly, six sigma is a management philosophy.  It is a customer based approach realizing that defects are expensive.  Fewer defects mean lower costs and improved customer loyalty.  The lowest cost, high value producer is the most competitive provider of goods and services.  Six Sigma is a way to achieve strategic business results.
 
Secondly, six sigma is a statistic.  Six Sigma processes will produce less than 3.4 defects or mistakes per million opportunities.  Many successful six sigma projects do not achieve a 3.4 ppm or less defect rate, which indicates that there is still opportunity.
 
Thirdly, six sigma is a process.  To implement the six sigma management philosophy and achieve the six sigma level of 3.4 defects per million opportunities or less, there is a process to be used.  The Six Sigma process is Define, Measure, Analyze, Improve, and Control (DMAIC).
 
6 Sigma Methods

All 6S projects go through the followings stages:

  1. Project selection targeting at under performing business processes or products.
  2. Process exploration. On this stage the business process is formalized into Y=F(Xs) function, where Y is important characteristic of the product or process and Xs are inputs bringing variations to the Y.
  3. Statistical analysis of the elements of Y=F(Xs) formula. Variations in Y are reduced, and performance is improved.
  4. Business plan to implement/sustain achieved improvements.
