This book summarizes the iTLS approach, a unique integration of 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. This Executive edition is designed for the senior 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.  Those who would like more depth on any section may benefit from the iTLSBOK (iTLS Body Of Knowledge) book, which deals with the details of “how” and is directed at those responsible for implementing iTLS.
