The Goal

The TL;DR

A plant manager named Alex Rogo has ninety days to save his factory from closure — and in the process, learns the Theory of Constraints. Goldratt's business novel makes operations visceral and unforgettable. The core thesis: the goal of any business is to make money, and only three metrics matter — throughput, inventory, and operating expense. Every system has exactly one constraint at any given time. An hour lost at the bottleneck is an hour lost for the entire system forever. The answer isn't to optimize every station; it's to subordinate everything else to the constraint, exploit it fully, and then elevate it. The Five Focusing Steps provide a practical algorithm that applies to any workflow, from manufacturing to software teams.
