Process Mastery was written by a real world practitioner. Highly competent in both the technical aspects of the methodology and the psychology of change and human behaviour, the author has carefully blended both ends of the change spectrum into a reference for improvement leaders. It is profound in its simplicity and provides easy, chronological access to the tools. Each of the DMAIC chapters is concluded with a comprehensive tool users guide and checklists and tollgate questions. You are not expected to read it, rather it was written for you to reference it and take away something new every time you opened it.
