PK0-005 Project Management Concepts Practice Question
A project manager is leading a team to develop a new mobile application. The project has a fixed budget and a strict deadline. During the execution phase, the stakeholder requests additional features that were not originally planned. Which project constraint is most directly affected by this request?
⚠ Common exam trap
PK0-005 often tests the triple constraint; candidates may pick schedule or cost because the request will ultimately affect them, but the question asks which constraint is most directly affected—the addition of features is a scope change first.

Correct answer & explanation
✓
Scope
The project constraint most directly affected by a stakeholder request for additional features is scope. Scope defines what is included in the project; adding unplanned features expands the scope. While schedule and cost may also be impacted due to the fixed budget and deadline, the request itself is a scope change, which then triggers trade-offs with the other constraints.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Quality
Why it's wrong here
Quality is a performance attribute degraded by cutting testing or review, not the constraint directly altered by adding unplanned features; scope changes first, then cost or schedule absorb the impact. Quality is tempting because rushed delivery often suffers, making it correct when the team compresses verification to meet a fixed date.
- ✓
Scope
Why this is correct
Additional features fall outside the agreed deliverables, directly expanding the project scope. With budget and deadline fixed, this unplanned work creates a triple-constraint conflict: the new requirements cannot be absorbed without either increasing cost, extending the schedule, or renegotiating what was originally committed.
- ✗
Schedule
Why it's wrong here
Adding unplanned features consumes extra effort, but the stem already fixes the budget and deadline, so the immediate constraint hit is scope, not time; schedule shifts only once the added work is estimated and re-baselined. Schedule is the tempting answer because extra features usually extend duration, making it correct when the deadline is flexible.
- ✗
Cost
Why it's wrong here
Cost rises only after the added features are estimated and resourced; the request itself changes scope, and with a fixed budget the manager must negotiate trade-offs rather than assume new funding. Cost is tempting because extra work consumes money, making it correct when the budget is flexible and scope is fixed.
