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?
Resource leveling adjusts start and finish dates to match resource availability.
Why this answer
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.
Exam trap
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.
How to eliminate wrong answers
Option A is wrong because crashing is a schedule compression technique that adds resources or increases work hours to shorten the schedule, not to adjust for limited resource availability. Option C is wrong because fast tracking involves performing activities in parallel that were originally sequential, which increases risk and does not address resource availability constraints. Option D is wrong because the critical path method (CPM) calculates the longest path of dependent activities and determines the shortest project duration, but it does not inherently adjust for resource limitations or partial availability.
