This document discusses the critical chain project management concept introduced by Dr. Eliyahu Goldratt to help projects finish on time and budget. It outlines the five steps: 1) identify constraints, 2) exploit constraints, 3) subordinate everything else to the constraints, 4) elevate constraints, and 5) don't let inertia become new constraints. Buffers are added to the critical chain to account for risks. Tracking focuses on the remaining work in the critical chain and buffers rather than completed work. When properly implemented, critical chain management can improve project team effectiveness, tracking, and decision making to help ensure on-time completion.
