The Five Focusing Steps are the operational core of theory-of-constraints — a repeating managerial cycle that directs attention systematically to the factor most limiting a system's performance. eliyahu-goldratt first articulated them explicitly in theory-of-constraints-book (1990), though the underlying logic was already present in the-goal (1984) through the character of Alex Rogo's plant-floor discoveries.
The five steps are:
1. Identify the system's constraint — the single resource, policy, or factor that limits throughput. 2. Exploit the constraint — get maximum output from it without significant additional investment. 3. Subordinate everything else — align all non-constraint resources to support the constraint's pace, not their own local efficiency metrics. 4. Elevate the constraint — if throughput is still insufficient after exploitation and subordination, invest in increasing the constraint's capacity. 5. Repeat — once a constraint is broken, return to step one, because the constraint will have shifted.
The subordination step (step 3) is the most counterintuitive and the most frequently violated. Conventional management rewards local efficiency, which leads non-constraints to overproduce, creating excess inventory and masking the true constraint. drum-buffer-rope is the scheduling mechanism that operationalizes subordination in production environments, and buffer-management provides the ongoing monitoring signal.
The cycling nature of the process distinguishes TOC from one-time optimization. Goldratt called this the "process of ongoing improvement" (POOGI). The steps apply wherever a system has a goal — manufacturing, projects (critical-chain-project-management), supply chains, and beyond. The financial lens for evaluating each step's impact is provided by throughput-accounting.
