Abstract
The first part of this chapter describes what Six Sigma is, why we need Six Sigma, and how to implement Six Sigma in practice. A typical business structure for Six Sigma implementation is introduced, and potential failure modes of Six Sigma are also discussed. The second part describes the core methodology of Six Sigma, which consists of five phases, i.e., define, measure, analyze, improve, and control (DMAIC). Specific operational steps in each phase are described in sequence. Key tools to support the DMAIC process including both statistical tools and management tools are also presented. The third part highlights a specific Six Sigma technique for product development and service design, design for Six Sigma (DFSS), which is different from DMAIC. DFSS also has five phases: define, measure, analyze, design and verify (DMADV), spread over product development. Each phase is described and the corresponding key tools to support each phase are presented.
In the forth part, a real case study on printed circuit board (PCB) improvement is used to demonstrate the application of Six Sigma. The company and process background is provided. The DMAIC approach is specifically followed and key supporting tools are illustrated accordingly. At the end, the financial benefit of this case is realized through the reduction of cost of poor quality (COPQ).
Finally, last part is given over to a discussion of future prospects and conclusions.
