1. Scenario:
You’re managing a software development project. A stakeholder requests a new feature that requires additional time. You want to meet the original deadline without cutting scope. What should you consider first?
A. Crashing the schedule
B. Re-baselining the schedule
C. Fast tracking activities
D. Extending the schedule
✅ Answer: C. Fast tracking activities
Explanation: Fast tracking allows you to perform activities in parallel that were initially planned in sequence, potentially meeting the deadline without altering the scope. However, it may increase risk.
2. Scenario:
While reviewing the schedule, you notice one activity has zero total float. What does this indicate?
A. It can be delayed without impacting the project
B. It's ahead of schedule
C. It’s on the critical path
D. It has slack time
✅ Answer: C. It’s on the critical path
Explanation: Zero float indicates a critical activity—any delay here will delay the entire project.
3. Scenario:
You are reviewing progress with your team and find SPI = 0.80. What does this suggest?
A. Project is ahead of schedule
B. Project is behind schedule
C. Project is on schedule
D. You are under budget
✅ Answer: B. Project is behind schedule
Explanation: Schedule Performance Index (SPI) < 1 means the project is not progressing as planned schedule-wise.
4. Scenario:
The client wants a product delivered earlier. You add more resources to critical path activities to compress the timeline. What technique is this?
A. Lead time
B. Crashing
C. Fast tracking
D. Resource smoothing
✅ Answer: B. Crashing
Explanation: Crashing involves adding resources to speed up critical path activities, often at a higher cost.
5. Scenario:
During planning, you can't define the detailed schedule for all phases. You decide to plan the near-term work in detail and the future phases at a high level. What technique are you using?
A. Bottom-up estimating
B. Decomposition
C. Rolling wave planning
D. Monte Carlo simulation
✅ Answer: C. Rolling wave planning
Explanation: Rolling wave planning allows for progressive elaboration of work as it becomes clearer over time.
6. Scenario:
You’re sequencing activities and decide to use a Finish-to-Start relationship with a 3-day lag. What does this mean?
A. The successor can start immediately
B. The successor starts 3 days after the predecessor finishes
C. The predecessor must wait 3 days
D. There is no dependency
✅ Answer: B. The successor starts 3 days after the predecessor finishes
Explanation: A lag in a Finish-to-Start relationship delays the start of the next activity after the previous one ends.
7. Scenario:
Your project has been experiencing repeated schedule delays. You want to prevent further slippage and closely monitor future progress. What should you implement?
A. Monte Carlo simulation
B. Schedule compression
C. Schedule forecasting
D. Schedule baseline
✅ Answer: C. Schedule forecasting
Explanation: Forecasting helps you predict future schedule performance and take action before delays occur.
8. Scenario:
A team member suggests working on two tasks at the same time to speed up delivery, even though they were originally planned sequentially. What risk management concern does this raise?
A. Lack of quality
B. Increase in project cost
C. Schedule baseline violation
D. Increased risk of rework
✅ Answer: D. Increased risk of rework
Explanation: Fast tracking activities increases the risk of errors and rework due to incomplete predecessors.
9. Scenario:
You're updating the project schedule after approving a change request that adds a new deliverable. What should be updated first?
A. Activity list
B. Schedule baseline
C. WBS dictionary
D. Risk register
✅ Answer: A. Activity list
Explanation: Once scope changes are approved, new activities must be identified and added to the activity list before re-baselining.
10. Scenario:
Two critical path activities overlap due to a recent change. The client asks for assurance that the new timeline is feasible. Which technique should you use?
A. Crashing
B. Schedule compression
C. Simulation (e.g., Monte Carlo)
D. Parametric estimating
✅ Answer: C. Simulation (e.g., Monte Carlo)
Explanation: Simulations help assess schedule feasibility and understand variability in timelines, especially after changes.
