Six Sigma for Green Belts and Champions: Foundations, DMAIC, Tools, Cases, and Certification , has numerous features that make this book unique.

• Contains coverage of the foundations of management necessary for professional Six Sigma management. This includes how to deploy an organization's mission statement throughout an organization through a cascading and interlocking system of key objectives and key indicators, called a dashboard. It is illustrated with many practical and relevant examples.

• Presents a thorough and detailed anatomy of the Six Sigma improvement model, called the DMAIC model. DMAIC is an acronym for DefineMeasureAnalyze Improve-Control. The DMAIC model is a well-tested vehicle for guiding an improvement team through the maze of a complex process improvement project.

• Integrates coverage of Six Sigma management with detailed coverage of those statistical methods that are appropriate for Green Belt and Champion certification. Each statistical method is explained and applied to an example involving actual data in a quality improvement context. Coverage of statistics begins with an introduction and basic definitions, along with graphs and descriptive statistical measures; provides critical insights into probability and probability distributions; and covers the essential topics of confidence intervals, hypothesis testing, design of experiments, and control charts, all from an applied quality improvement perspective. Output from the Minitab statistical software package, widely used in Six Sigma management, is illustrated.

• Includes chapter ending appendixes that provide step-by-step instructions for using Minitab Version 14 for the statistical methods covered in each chapter.

• Includes two case studies in Six Sigma management. Each case study provides a detailed examination of all the steps involved in using the DMAIC Six Sigma approach. One case is from a service industry, and the other relates to manufacturing.

• Includes information on Champion and Green Belt certification exams, along with sample test questions.
