This set of tools embodies the whole TOC and helps identify and manage constraints in projects. Nowadays, from a project management perspective, multiple tools derived from the TOC have been developed, also known as Thinking Processes (TP). On the other hand, for any type of project management, the Critical Chain Project Management) (CCPM) has been developed. Looking at manufacturing management, the primary methodology used is the DBR, standing for Drum-Buffer-Rope. The first application of TOC was for manufacturing but it has evolved and is now applicable for any type of project management. These Five Focusing Steps are : Identify, Exploit, Subordinate, Elevate and Warning. To do so, five steps have been definedĪs the key steps of all the methods derived from TOC. The overall goal is to eliminate these constraints in order to enhance performance. These limiting factors or constraints, also referred as bottlenecks, are slowing down the process of a system. Indeed, among these activities, one acts as a constraint upon the entire system, i.e. It considers every system as a chain of activities that operates one after another and hypothesizes that this chain is not stronger than its weakest link. TOC is based on an iterative method for improvement. This theory is a problem-solving management method. Goldratt as well as other contributors and has become a notable method in the world of management. It has been developed continuously since then by Dr. Eliyahu Goldratt in his bestselling novel « The Goal ». The Theory of Constraints (TOC) was introduced in 1984 by Dr.
