Your project is running behind schedule. You need to compress the schedule without significantly increasing cost. Which TWO techniques should you consider?
Adding resources from non-critical path activities to critical path tasks is a valid schedule compression technique known as crashing. By reallocating existing resources that have float to activities directly impacting the project's end date, the duration of critical path tasks can be reduced. This approach effectively shortens the overall project schedule without necessarily incurring additional direct costs for new resources, making it a cost-effective method when internal resources are available.
Why this answer
Adding resources from non-critical path activities to critical path tasks is a form of resource leveling or resource optimization that can compress the schedule without significant cost increase, as it reallocates existing resources rather than hiring new ones. Option B is correct because fast-tracking involves performing activities in parallel that were originally planned sequentially, which can reduce the project duration without adding costs, though it may increase risk.
Exam trap
The PMP exam often tests the distinction between schedule compression techniques (fast-tracking and crashing) and unauthorized scope or quality changes, so candidates may mistakenly choose options that seem to save time but violate project management processes.
