In a production system, which term describes the resource whose capacity is less than demand and thus often limits throughput?

• A. Break-bulk
• B. Buffer
• C. Bottleneck
• D. Breakpoint

Answer: (C)

A bottleneck is the resource whose capacity is less than demand and thus often limits throughput. In a production system, the overall rate at which finished products can be produced is governed by the slowest or most overloaded part of the process. That resource constrains the flow, so even if other steps have spare capacity, the system’s output cannot exceed the bottleneck’s rate. You’ll typically see work pile up before the bottleneck and the bottleneck itself runs continuously to its capacity, driving the overall pace of production. Improving the system’s performance usually means easing the bottleneck—adding capacity there, smoothing its workload, or otherwise elevating its effective throughput—since boosting non-bottleneck steps won’t raise the system’s maximum output until the bottleneck is addressed. The other terms aren’t describing the limiting resource: break-bulk relates to dividing shipments, buffer refers to protective inventory or decoupling stock, and breakpoint isn’t a standard term for this concept.
