Question

Quizplus · Accepted Answer

Breaking the binding constraint means identifying and improving the process that is currently limiting the overall performance of the system. This way, the system can operate at its maximum potential and create more value. Improving all processes simultaneously or making across-the-board cuts may not address the root cause of the problem, and optimizing the contribution margin of individual items is not the main goal of theory of constraints. Therefore, option A is the best choice.
