This book deals with the details of “how” and “why” and is directed at those responsible for implementing iTLS, a unique approach for integrating the Theory of Constraints (TOC), Lean, and Six Sigma methodologies where the financial and other benefits of applying together are significantly larger than applying the techniques separately. 

Any professional responsible for making significant contributions to the performance of their organization could benefit from application of iTLS. You will find that your performance results will improve quickly and tangibly. Positive results include improved customers´ experiences, increased throughput, reduced costs, and better leadership. Authors Pirasteh and Fox know the core problem of what causes various improvement approaches to fail, and in response provide a new model that combines TOC, Lean, and Six Sigma into a unique program called TLS. When TOC, Lean, and Six Sigma (iTLS) are combined in a unique fashion results improve dramatically. A scientifically conducted study in the United States showed that iTLS projects produced more than four times the benefits of either Lean or Six Sigma projects. Subsequent experiences in other countries have produced even greater benefits. iTLS has been implemented in 15 countries in a variety of operations, including discrete and transactional environments, with phenomenal success. The resulting benefits include significant improvements in quality, productivity, and profitability. Authors also have developed an understanding of how these internal improvements can be further leveraged to increase sales, market share, and profits.

If your intention is to learn how to systematically improve quality, process reliability, and throughput while creating a wasteless enterprise, then this book is for you!

An Executive edition is available for senior leaders and decision-makers who decide “if” their company should adopt an iTLS approach and would like to quickly understand the essence of the best way to implement continuous improvement approaches to gain the maximum results rapidly.
