The answer is resource leveling, the correct technique to adjust a schedule when a resource is available only 50% of the time. Resource leveling directly addresses resource constraints by modifying task start and finish dates to match the limited availability, preventing over-allocation and ensuring the resource’s work is spread across the timeline proportionally. On the Project Management Professional PMP exam, this scenario tests your understanding of how resource leveling handles partial availability, often appearing in questions about schedule compression or resource optimization traps—common pitfalls include confusing it with resource smoothing, which does not extend the project duration. Remember the memory tip: “Leveling limits, smoothing stays within float”—leveling adjusts for constraints like 50% availability, potentially lengthening the schedule, while smoothing only shifts tasks within existing slack.
PMP Process — Managing Technical Aspects Practice Question
This PMP practice question tests your understanding of process — managing technical aspects. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is developing the project schedule and needs to account for a resource that is only available 50% of the time. Which technique should be used to adjust the schedule?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Resource leveling
Resource leveling is the correct technique because it adjusts the schedule to account for resource constraints, such as a resource being available only 50% of the time. This technique modifies start and finish dates based on resource availability, ensuring the resource is not over-allocated. In this scenario, leveling would spread the resource's work across the schedule to match the 50% availability, potentially extending the project duration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Crashing
Why it's wrong here
Crashing adds resources to shorten duration, but does not adjust for limited availability.
✓
Resource leveling
Why this is correct
Resource leveling adjusts start and finish dates to match resource availability.

✗
Fast tracking
Why it's wrong here
Fast tracking performs activities in parallel, increasing risk, not resolving resource constraints.
✗
Critical path method
Why it's wrong here
Critical path method focuses on sequence and duration, not resource availability.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse resource leveling with schedule compression techniques like crashing or fast tracking, mistakenly thinking they can adjust for resource constraints when they are designed to shorten the schedule, not manage limited availability.
Detailed technical explanation
How to think about this question
Resource leveling is often applied using algorithms that consider resource calendars and availability constraints, such as a resource being available only 50% (e.g., 4 hours per day). Under the hood, this can cause the critical path to change if the constrained resource is on a critical activity, potentially creating a new resource-critical path. In real-world scenarios, this is common in matrix organizations where shared resources (e.g., a senior engineer) split time across multiple projects, requiring leveling to avoid overallocation and schedule conflicts.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
