Many total quality management methodologies have been introduced in recent decades. Six Sigma has emerged as a breakthrough methodology. With Six Sigma, we are solving problems and improving processes using as our basis one of the most powerful tools of human development: the scientific method. The basis of the Six Sigma methodology is the DMAIC cycle. It consists of five stages: define, measure, analyze, improve, and control. The roles of people involved in Six Sigma projects are also an important issue. Using martial arts comparisons, these roles can be categorized into Master Black Belts, Black Belts, Green Belts, Yellow Belts, Champions, and Managers. In this chapter, we give an overall view of Six Sigma and a basic description of the interaction between the different elements involved in this methodology.
