Despite the pervasiveness of Six Sigma programs, there is a rising concern regarding implementation failures. One reason many of these implementations fail is because rigorous research is lacking on how to effectively guide implementation. Using a successful Six Sigma program in a network technology company as a case study, this research develops a six-step implementation model. The first step is to perform market-driven strategic analysis. The second is to establish a cross-functional team to drive the initiative. The third step is to identify overall improvement tools. The fourth is to perform process mapping and prioritize improvement opportunities. The fifth step is to develop a detailed plan for low-level improvement teams, and the final step is to implement, document, and revise as needed. We identify key managerial implications of our implementation experience and provide several directions for future research.
