The document outlines the five steps of the Theory of Constraints for improving a system: 1) Identify the system's constraints, 2) Decide how to exploit the constraints, 3) Subordinate all other decisions to exploiting the constraints, 4) Elevate the constraints, and 5) If elevating breaks a constraint, return to step 1. It provides examples of applying these steps to identify and address bottlenecks in a manufacturing system to maximize throughput.
