In the theory of constraints, the pace of a bottleneck production operation is controlled by the pace of which element?

In the theory of constraints, the pace of a bottleneck production operation is effectively controlled by its capacity, which is inherently linked to the concept of the "weakest link." The bottleneck represents the limiting factor in the production process that restricts overall output, and it does so by determining the maximum rate at which products can be processed through the entire system.

The idea behind the weakest link is that in any process, the slowest component will cap the performance of the entire system. Therefore, even if other operations are capable of producing at a faster speed, the entire production flow is ultimately limited by the bottleneck. This means that to enhance overall throughput, one must address and optimize the weakest point in the process. Thus, the bottleneck dictates the rhythm of production, and any improvements surrounding it would not yield significant advantages unless the bottleneck itself is effectively managed.
