Every system, whether it is a factory floor, a hospital, or a software development team, has one part that limits how much the whole system can produce. This single limiting factor is called the constraint, and it determines the overall output no matter how efficient the rest of the system is. The Theory of Constraints treats this idea as the starting point for any improvement effort, arguing that fixing things that are not the bottleneck rarely changes the final result. Identifying the constraint is not always obvious because it can…
