ITPEC IP October 2025 — Question 15 of 100
Bottleneck — the slow component limits the performance achievable by the entire system.
Even if other components have unused capacity, work cannot flow faster than the constrained stage can process it. Identifying and improving the bottleneck therefore often gives a larger overall benefit than optimizing already-fast parts.
Answer (d)
Why not others:
- (a) Throughput is the amount of work completed per unit time, not the limiting component
- (b) Defragmentation reorganizes stored data blocks
- (c) Flowchart is a diagram of processing steps and decisions
Key rule: End-to-end performance is governed by the tightest constraint; optimize the bottleneck before components that do not limit the flow.
