I. INTRODUCTION The Beginnings of Six Sigma Companies have spent millions of dollars and countless hours trying to lower production costs and reduce the amount of rejected items. A revolutionary principle that attempts to solve these problems was first developed by Motorola Corporation and is known as the Six Sigma concept. This concept was first introduced in the early 1980s and only became widely known about ten years later. By this time General Electric CEO Jack Welch and Allied Signal CEO Larry Bossidy had given some credibility to the Six Sigma concept through the success of their own organizations (Pheng and Hui 2004). Six Sigma has since become a fairly common quality concept.II. WHAT IS SIX SIGMASix Sigma DefinedSix Sigma has successfully moved away from other conceptual qualities through its focus. This concept focuses on “communication of measurable error ratios” (Williamsen 2005: 41). The goal of Six Sigma is to achieve an “error ratio of three parts per million with an incidence of 99.9996%” (Williamsen 2005: 41). The men who initially developed the Six Sigma concept, Harry and Schroeder, define Six Sigma as “a disciplined method that blends extremely rigorous data collection and statistical analysis to identify sources of errors and ways to eliminate them” (Pheng and Hui 2004: 482 ). . Before the introduction of Six Sigma, quality meant producing products to a standard and ensuring that they did not go outside previously specified limits. Post Six Sigma has expanded the definition of quality to include both the economic value created by the product and the practical uses of it for those who use it and those who produce it (Pheng and Hui 2004).
