“Six Sigma” quality is a buzzword in the quality community throughout the world. “Six Sigma” quality is defined as achieving reduction in the variation which allows for a ± 1.5 sigma shift (Harry Mikel 1997). It is also described as a philosophy, methodology, and a breakthrough strategy to solve problems. This paper presents an in-depth examination into the heads and tails of the “six-sigma quality” concept. The objective is to become better informed about the benefits of six-sigma quality. Actual examples and case studies illustrate its merits and warn against limitations and misuses. The ultimate objective is to understand six-sigma quality and place it in an appropriate context to reap the benefits.
