Six Sigma is a system for improving the quality of organizational processes and products to a level of 3 defects per million--the "six sigma" level of quality. It was originally developed at Motorola in the 1980's and has become one of the most widely discussed and reported trends in business over the past two years, thanks largely to the phenomenal successes of the Six Sigma program at GE, where CEO Jack Welch credits it with millions of dollars in annual cost savings and product quality improvements. Due to the widespread coverage of the Six Sigma program by the business press over the last two years, there is strong demand for books and information on how Six Sigma works and how to implement it. The Six Sigma Handbook is designed for the manager or quality professional who is already familiar with Six Sigma and wants a guide to the basic quality tools and statistics that are the foundation for Six Sigma. In addition to providing a brief overview of the management and organization of Six Sigma, and the underlying philosophy, the book explains in detail the problem-solving techniques and statistical tools most often used in Six Sigma.
