PK0-005 Project Management Concepts Practice Question
A project manager is reviewing the project constraints. The triple constraint traditionally includes scope, time, and cost. However, quality is also often considered a constraint. Which TWO of the following are part of the triple constraint? (Select TWO).
⚠ Common exam trap
PK0-005 often tests whether candidates include Quality in the triple constraint — Quality is the central outcome, not one of the three legs (Scope, Time, Cost).

Correct answer & explanation
✓
Time
The triple constraint, also called the project management triangle, consists of scope, time, and cost (or schedule and budget). Option A (Time) is correct because schedule/duration is one of the three foundational constraints that must be balanced against the others. Option B (Scope) is correct because the defined deliverables and work required form another core leg of the triangle. Option C (Quality) is not part of the traditional triple constraint; it is often described as a fourth dimension affected by the balance of the three. Option D (Resources) and Option E (Risk) are broader project factors or knowledge areas, not the classic triple constraint components.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Time
Why this is correct
The traditional triple constraint comprises scope, time and cost. Time is one of those three axes, so it satisfies the stem's requirement to identify a triple-constraint component, distinct from quality, which sits outside the classic trio.
- ✓
Scope
Why this is correct
Scope defines the full set of deliverables and boundaries of the project, directly governing what work is authorised. It forms one of the three interdependent legs of the triple constraint alongside time and cost, so any change to scope forces compensating adjustments elsewhere. This satisfies the stem's requirement for a genuine triple-constraint component.
- ✗
Quality
Why it's wrong here
Quality is a derived constraint that sits alongside the triple constraint, not within it; scope, time and cost are the three traditional axes. It is tempting because quality is genuinely managed as a constraint in many methodologies, and would be the right answer if the question asked which factor is often added to the triple constraint.
- ✗
Resources
Why it's wrong here
Resources belong to the expanded project management triangle (with risk and quality), not the traditional triple constraint of scope, time and cost. It is tempting because resource availability genuinely constrains schedules and budgets, and would be correct if the question asked about the competing constraints model rather than the classic triple.
- ✗
Risk
Why it's wrong here
Risk is a separate project constraint, not one of the triple constraint's three elements, which are scope, time and cost. It is tempting because risk management is central to projects and often listed alongside constraints, but it does not define the traditional triple constraint itself.
