CAPM Practice: Demonstrate an understanding of a project management plan schedule

Crashing adds resources (people, equipment, overtime) to critical path activities to reduce their duration. It typically increases cost because more resources are applied. Crashing should be applied to activities where the cost-duration trade-off is most favorable (shortest duration reduction for least additional cost).

**Why not A:** Resource leveling resolves resource over-allocation by adjusting activity timing, often extending the schedule. It does not shorten the schedule — in fact, it typically lengthens it. Resource leveling is a constraint resolution technique, not a schedule compression technique.

**Why not C:** Schedule compression through scope reduction is not a recognized compression technique. Reducing scope changes what the project delivers, which requires formal change control. True schedule compression (crashing and fast tracking) maintains the original scope while shortening duration.

**Why not D:** Fast tracking involves performing sequential activities in parallel, not adding resources to make activities faster. The question describes adding additional resources to critical path activities, which is the definition of crashing, not fast tracking.
