This is an individual chapter of Theory of Constraints Handbook. âEURœMaking Change StickâEUR shows you how to make your application prepares far more efficient. It starts by examining why modification does not happen: why our efforts frequently cause far less benefits than we had anticipated, and why the benefits we do attain decrease gradually. It then explains a meta-process called the âEURœCycle of ResultsâEUR or CORE, an efficient design for both creating and assessing application strategies. CORE is compared to other company procedures, consisting of sales, DemingâEUR ™ s Plan-Do-Check-Act cycle, and the TOC Five Focusing Steps. It is then put on application planning, with particular emphasis on Critical Chain applications.
