PK0-005 Practice Question: During project planning, the team identifies that…
During project planning, the team identifies that a key developer is only available 50% of the time. This is an example of which type of constraint?
⚠ Common exam trap
PK0-005 often tests the confusion between resource constraints and schedule constraints, as limited availability can impact the schedule, but the root cause is resource availability.

Correct answer & explanation
✓
Resource constraint
A resource constraint refers to limitations on the availability of resources, such as personnel, equipment, or materials. The key developer being available only 50% of the time is a classic example of a resource constraint because it restricts how much work can be assigned to that person.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Technical constraint
Why it's wrong here
Availability of a person is a resource constraint, not a technical one; technical constraints concern solution architecture, tools or standards. It tempts because the developer's skill is technical, but the limiting factor here is their time, which belongs in resource planning.
- ✓
Resource constraint
Why this is correct
A key developer available only half the time limits the amount of labour the project can apply, which is a resource constraint. Resource constraints concern the availability, quantity or capability of people, equipment or materials, distinct from time, cost or scope limitations.
- ✗
Schedule constraint
Why it's wrong here
Schedule constraints govern the project timeline and deadlines, not the quantity of a resource's available working time. A developer available only 50% is a resource constraint; schedule would apply if the completion date itself were fixed or compressed.
- ✗
Cost constraint
Why it's wrong here
Cost constraint concerns the approved budget and funding limits for the project. A developer's 50% availability restricts time, not money, so it maps to the schedule constraint; cost would apply if the budget for that resource were capped.
