The document discusses the Theory of Constraints (TOC), a management paradigm that views any system as being limited by a small number of constraints. It explains that TOC uses the "five focusing steps" to identify the system's constraint, exploit it, subordinate everything else to it, elevate it, and ensure it does not reoccur. The document provides details on each step and emphasizes that TOC views continuous improvement as an ongoing process of addressing constraints through efficient management and leadership.
