The document discusses the components of DMAIC, the methodology used in Six Sigma improvement projects. It begins by outlining some key requirements for Six Sigma projects, including leadership commitment, using facts to make decisions, and cross-functional team training. It then describes each stage of DMAIC - Define, Measure, Analyze, Improve, and Control - and lists some potential tools and activities used in each stage. The document concludes by listing several statistical tools that can be used throughout the Six Sigma improvement process.
