The Six Sigma phenomenon has followed the TQM movement as the latest thrust for many companies seeking to improve their performance and effectiveness. The purpose of this paper is to review the basic concepts of Six Sigma, its benefits, and successful approaches for implementation. In particular, we benchmark the practices of the General Electric Company, one of the leaders and innovators in implementing the process. We conclude that keys for successful implementation include upper management support and involvement, organizational infrastructure, training, tools, and links to human resources‐based actions.
