Theory of Constraints (TOC)
A management philosophy developed by Dr. Eliyahu M. Goldratt that is broken down into three interrelated areas - logistics, performance measurement, and logical thinking. Logistics include drum-buffer-rope scheduling, buffer management, and VAT analysis. Performance measurement includes throughput, inventory and operating expense, and the five focusing steps. Logical thinking includes identifying the root problem (current reality tree), identifying and expanding win-win solutions (evaporating cloud and future reality tree), and developing implementation plans (prerequisite tree and transition tree).
