What is the Theory of Constraints primarily about?

• A. Managing bottlenecks to maximize throughput.
• B. Reducing inventory to zero.
• C. Automating bottlenecks.
• D. Forecasting demand fluctuations.

Answer: (A)

Bottleneck management to maximize throughput. The Theory of Constraints focuses on the one part of a process that most limits overall output—the bottleneck—and it teaches you to structure the entire system around that constraint. By exploiting the bottleneck (keeping it busy), subordinating every other step to its pace, and eventually elevating the bottleneck’s capacity, the system’s total throughput rises. The goal is the rate at which the system generates money, not simply pushing inventory to zero or automating parts regardless of impact. Buffers protect the constraint and help synchronize the flow, but the core idea is to identify and manage the bottleneck to improve flow. Forecasting demand fluctuations is about planning, not the central focus of TOC.
