Six Sigma is a systematic approach to making significant or breakthrough process improvements. Currently, Six Sigma exists as a team-based problem-solving approach applied by trained project facilitators, which are typically called belts. Depending on the level of expertise in the methodology and improvement tools, belts can be White, Yellow, Green, Black, and Master Black Belts (MBBs). The Master Black Belt is the highest level of expertise in Six Sigma approaches, tools, and techniques.

In companies implementing Six Sigma, the role of Master Black Belt is to train, guide, and coach Black and Green belts to execute their improvement projects efficiently. In addition to this, Master Black Belts are often responsible for overseeing the organization’s entire improvement program with the ultimate responsibility for creating a robust culture of continuous improvement. Thus, the competence of MBBs is critically important for the success and long-term sustainability of Six Sigma in organizations.

This book is ideal for all those who wish to get trained and certified as Master Black Belts and train others to achieve breakthrough results using Six Sigma to shape and execute improvement projects. The book has the right balance between topics such as strategic planning, project selection, stakeholder management, and training design, to advanced statistical techniques such as propagation of errors, destructive measurement systems, general linear models and components of variation, and complex blocking structures in Design of Experiments. This book was written by three expert Master Black Belts certified by the American Society for Quality (ASQ). Moreover, they are from different parts of the world and industry, which brings great diversity to the contents of the book.
