The inescapable conclusion from this study was that the interactive effects of iTLS were superior to the individual results obtained from using either Lean or Six Sigma. For the last decade we have been using a comparable improvement methodology—first reported in the book, The Ultimate Improvement Cycle —and we have achieved analogous results. Although our step by-step method, or pathway, is somewhat different than the Pirasteh and Fox method, the basic beliefs are exactly the same. Significant bottom-line improvement can be achieved when using an integrated approach of TOC, Lean and Six Sigma, as compared to using individual TOC, Lean, Six Sigma or Lean-Six Sigma methodologies. If you are truly interested in improving what your company does and how they do it, then arming yourself with the concepts of the TLS methodology should certainly point you in the right direction. The TLS approach is most likely not the end point in this game, but rather just a step to achieve the next level of understanding. There will be more and possibly even better methods proposed for future use. But as it stands today, understanding and implementing TLS carries the potential to lift your organization to heights not even dreamed of a few years ago. Good luck on your adventure.
