Introduction

So it is with Six Sigma methodology. Many claim to know it, and others claim they have done it. The fact of the matter is, however, that inconsistencies exist in Six Sigma implementation, training, and results. This is partly due to the fact that, as of this writing, there still is no recognized body of knowledge (BOK) (the reader should be aware that the published American Society for Quality (ASQ) and others, including the author’s, that have attempted to identify the BOK have not been met with 100% acceptance, including as regards certification). In addition, Six Sigma methodology is to a certain extent enshrouded in mystique. It is hoped that we will help diffuse this mystique and present the implementation and training in a format that many can use. We start by focusing on diffusion.
