PMI-SP Schedule Compression 5

Question 1

Which of the following BEST distinguishes fast tracking from crashing in terms of project risk?

Accepted Answer

Crashing increases cost risk; fast tracking increases rework and coordination risk

Answer

Crashing's primary risk is budget overrun, while fast tracking's primary risks are rework and coordination failures from overlapping activities.

Question 2

A project manager is using schedule compression during project execution. The approved schedule baseline shows a planned duration of 120 days, but compression brings it to 105 days. The 105-day schedule is now being used for performance measurement. What must have occurred?

Accepted Answer

A formal change request was approved, revising the baseline to 105 days

Answer

Updating the baseline for performance measurement requires a formally approved change request through the integrated change control process.

Question 3

In the context of schedule compression, what is a 'near-critical path' and why does it matter?

Accepted Answer

A non-critical path with little float that may become critical after compression

Answer

Near-critical paths have minimal float and can easily become critical when the primary critical path is compressed, requiring monitoring.

Question 4

A project manager applies crashing to reduce duration by 4 days. The total crash cost is $20,000 and the crash cost slope for each activity was $5,000/day. How many activity-days were crashed?

Accepted Answer

4 days

Answer

$20,000 total cost ÷ $5,000 per day = 4 activity-days crashed to achieve the 4-day reduction.

Question 5

Which PMI-SP scheduling concept directly supports the decision of WHEN to stop crashing an activity?

Accepted Answer

Crash limit — the point at which further resource addition yields no additional duration reduction

Answer

The crash limit defines the minimum achievable duration for an activity; crashing beyond this point is technically or physically impossible.
