Six Sigma Life Cycle

This chapter presents the Six Sigma Life Cycle approach, a framework that comprises two interlinked models: the Six Sigma Project Life Cycle model and the Technical System Life Cycle model. The Six Sigma Project LC model consists of a detailed and comprehensive process intended to guide managers and team leaders along all the relevant stages of a Six Sigma project, from identification to post-project, helping them to achieve the project’s goals with minimum expenditure of effort and resources. The Technical System LC model aims to assist them towards the best decision of which Six Sigma methodology, roadmap and toolbox should be used, depending on the degree and type of innovation that are involved in the project scope. Two case studies are described to demonstrate the practical application and usefulness of the framework.
