The document discusses the Theory of Constraints (TOC) management approach and its applications in a plant. TOC identifies the weakest link constraining an organization from achieving its goals. The plant aims to decrease inventory, costs and increase cash flow using the 5 steps of TOC: 1) identify constraints, 2) decide how to use bottlenecks, 3) use resources according to steps 1-2, 4) increase bottleneck efficiency, and 5) if new constraints emerge, return to step 1. TOC provides a new way to determine and address hindering factors compared to traditional methods.
