Theory of Constraints

Theory of Constraints (TOC) is an overall management philosophy that aims to continually achieve more of the goal of a system. If that system is a for-profit business, then the goal is to make more money, both now and in future. TOC consists of two primary collections of work: 1) The five focusing steps and their application to operations; 2) The Thinking Processes and their application to project management and human behavior.

Also called constraints management, it is a set of tools that examines the entire system for continuous improvement. The current reality tree, conflict resolution diagram, future reality tree, prerequisite tree and transition tree are the five tools used in its ongoing improvement process.
