PK0-005 Practice Question: A project manager is performing schedule…
A project manager is performing schedule compression because the project is behind schedule. The team decides to start a follow-on activity before its predecessor is fully completed. This approach increases the risk of rework. Which schedule compression technique is being used?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fast-tracking
Fast-tracking involves overlapping sequential activities, which increases risk. Crashing involves adding resources to the critical path, which increases cost. Both are schedule compression techniques, but the description matches fast-tracking.
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 extra resources to critical-path activities to compress the schedule, but it does not involve overlapping tasks or starting a successor before a predecessor finishes. The scenario explicitly describes starting a follow-on activity before its predecessor is fully completed, which is the defining mechanism of fast tracking, not crashing. Crashing would be tempting because it is a common compression technique for behind-schedule projects, and it would be correct if the team were instead allocating additional staff or overtime to accelerate a single critical-path task.
- ✗
Critical chain method
Why it's wrong here
Critical chain method uses buffers, not overlapping activities.
- ✓
Fast-tracking
Why this is correct
Fast-tracking overlaps activities normally done in sequence, increasing risk.
- ✗
Resource leveling
Why it's wrong here
Resource leveling adjusts start and finish dates based on resource constraints, not compression.
