Motorola originated the Six Sigma trademark, in the eighties. This strategy help identify the main reasons for errors in management and the production process in order to stop it from happening again. By applying Six Sigma, Motorola saved 17 billion dollars, through 2006.

The term "Six Sigma" is a reference to a field of statistics known as 'process capability studies.' PCS is the establishment of a manufacturing process that will produce a very high proportion of the output within the tolerances of the specifications. Processes that operate "six sigma" for a monitored period will produce reduced defect levels in the long-term production cycle.

A hallmark coinage that describes Six Sigma is "whatever leads to customer dissatisfaction" is gone or at least lessened. The Six Sigma Program is: Six Sigma Training, Six Sigma Certification, Six Sigma Black Belt Training and Certification, Six Sigma Green Belt Training and Certification, Six Sigma Online Training.

The series of quality management methods in a Six Sigma system involve the creation of an infrastructure within the host organization, delineated by Black Belts, the experts in their particular method, who mentor the Green Belts, the intermediate level, who in turn mentor other employees further down the rungs. The emphasis is on strong, involved management and support.

Like it's predesessors, Six Sigma seeks to achieve stable and predictable business processes that lead to business success. By identifying the manufacturing and business processes that can be measured, analyzed, improved and controlled, an organization may achieve and sustain an enviable record of nearly faultless production and business management.
