Many leaders and managers have led in improvement initiatives in a variety of different industry sectors. And most believe, when they begin these efforts, they have all the tools they need in their improvement "backpack." They are considered experts in efforts such as Total Quality Management, Preventive Maintenance, Statistical Process Control, Failure Mode and Effects Analysis, and Design of Experiments. And by using the tools from their respective "backpacks," they made substantial improvements to many kinds of processes in a wide array of industry segments. As time passes, however, most feel there is a missing link in their arsenal of tools for improvement. The author faced this same predicament, and he discovered what the missing link was in his improvement tool kit: Theory of Constraints (TOC). Once he learned the details of TOC, his ability to make major improvements jettisoned upward to levels he had not seen before. TOC is the common denominator in all the case studies presented in this book.

This book opens with a chapter on what Theory of Constraints is and why it works so well in improvement efforts. In the second and third chapters, this book covers the important points related to Lean Manufacturing and Six Sigma as well as key points related to variability. Chapter 4 demonstrates how to effectively combine these three components to achieve maximum improvement and the corresponding enhancement to your company’s profitability. The remainder of this book comprises true case studies from different industry segments, using this integrated improvement methodology.

Essentially, this book lays the foundation for what most practitioners are just beginning to understand—this integrated improvement methodology is superior to the three components used in isolation from each other. This book presents a step-by-step method of how to combine the Theory of Constraints, Lean, and Six Sigma, and then demonstrates its effectiveness in a very diverse array of industries.
