A Systematic Review on Critical Chain Project Management

Theory of Constraints (TOC) is the parent concept for the development of critical chain project management (CCPM). CCPM is the application of TOC. The project management literature has taken a keen interest in this. The key element of CCPM such as the Theory of Constraints, CCPM scheduling, Activity duration, types of buffers and their positioning, and buffer sizing techniques are reviewed by the author. This includes activity duration factors such as student syndrome and Parkinson’s laws. Multitasking affects project cost and CCPM & TOC provide the solution. The authors conclude that, even though CCPM contains several useful principles, it does not entirely address all project management requirements. As a result, companies should exercise extreme caution when excluding conventional project management techniques.
