PMI-SP Schedule Compression 3

Question 1

A project manager is crashing a construction project. After crashing activity X by 2 days, the critical path shifts to a new path. What should the project manager do next?

Accepted Answer

Recalculate the network and crash activities on the new critical path

Answer

When crashing changes the critical path, the PM must recalculate and continue crashing activities on the newly identified critical path.

Question 2

Which scenario represents a situation where NEITHER crashing NOR fast tracking is feasible?

Accepted Answer

All critical path activities have external mandatory dependencies that cannot be overlapped and no additional resources exist

Answer

If activities have hard external constraints preventing overlap and no additional resources are available, both compression techniques are infeasible.

Question 3

During a schedule review, the project manager identifies that two activities can be overlapped by 5 days with a lead time applied. This schedule compression approach is known as:

Accepted Answer

Fast tracking with lead

Answer

Applying lead time to allow activity overlap is the mechanism by which fast tracking is implemented in a schedule.

Question 4

A project manager is evaluating crashing options across four critical path activities. Which activity should be crashed FIRST?

Accepted Answer

Activity with the lowest crash cost per day

Answer

Crashing the activity with the lowest cost slope (cost per day saved) minimizes additional expenditure for each day of schedule reduction.

Question 5

Fast tracking is MOST appropriate when which condition exists?

Accepted Answer

Downstream activities can begin with preliminary outputs from upstream activities

Answer

Fast tracking works best when downstream activities can start using preliminary or partial outputs, allowing productive overlap.
