Unique Aspects of the Book
The Course on Six Sigma
Management has numerous features that make this book unique.
- Contains coverage of the
foundation 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,
and 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 Define - Measure - Analyze - 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 then 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 that provide a detailed examination of all the steps involved in
using the Define Measure Analyze Improve Control (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.
