CAPM Practice Question: Project Management Fundamentals and Core Concepts
A project is behind schedule and over budget. The sponsor asks the project manager to reduce costs without affecting the end date. Which constraint should the project manager consider adjusting?
⚠ Common exam trap
CAPM often tests the misconception that you can independently reduce cost without touching scope or time — candidates forget the triple constraint's interdependency and pick 'Resources' or 'Quality' as if they were standalone levers.

Correct answer & explanation
✓
Scope
The triple constraint (scope, time, cost) means you cannot change one without affecting the others. Since the sponsor explicitly wants to reduce costs without moving the end date, time is fixed and cost must decrease — the only remaining lever is scope. Reducing scope (descoping features or deliverables) lowers the work required, which in turn lowers cost while preserving the schedule.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Scope
Why this is correct
Reducing scope removes deliverables or features from the project, which lowers cost and effort while preserving the fixed end date. Adjusting scope is the constraint that can absorb the budget reduction without extending the schedule.
- ✗
Quality
Why it's wrong here
Reducing quality does not lower cost or shorten duration; it accepts defects and rework, which typically increases both. It is tempting because cutting inspection and testing appears to save money immediately, and trading quality is legitimate only when the sponsor explicitly accepts degraded scope or performance.
- ✗
Time
Why it's wrong here
Time is the constraint the sponsor explicitly said must not move, so extending or compressing the schedule contradicts the instruction. It is tempting because crashing the schedule is a familiar cost-reduction response, yet here the fixed end date rules it out as the adjustable constraint.
- ✗
Resources
Why it's wrong here
Adjusting resources changes who and how much capacity performs the work, but the sponsor's constraint is cost reduction with the end date fixed; adding or removing resources does not by itself resolve the budget overrun. It is tempting because resource levelling is a standard schedule-compression lever.
