PMI-SP Critical Path Method 5

Question 1

When compressing a schedule using crashing, which activities should be crashed first?

Accepted Answer

Critical path activities with the lowest crash cost per day

Answer

To minimize cost while compressing the schedule, crash critical path activities starting with those that have the lowest crash cost per day.

Question 2

A Finish-to-Finish dependency requires that the successor activity finishes no earlier than how many days after the predecessor's finish (with a 4-day lag)?

Accepted Answer

4 days after the predecessor finishes

Answer

A Finish-to-Finish relationship with a 4-day lag means the successor cannot finish until 4 days after the predecessor finishes.

Question 3

Which of the following is a limitation of the Critical Path Method?

Accepted Answer

CPM assumes unlimited resources are available

Answer

Traditional CPM assumes resources are unlimited and always available, which rarely reflects real-world project conditions.

Question 4

During schedule analysis, a project manager identifies that the critical path has changed after a status update. What is the MOST likely cause?

Accepted Answer

A non-critical activity was delayed beyond its total float

Answer

When a non-critical activity is delayed beyond its total float, it becomes critical and may create a new, longer critical path.

Question 5

In CPM scheduling, a 'dummy activity' in an AOA network is used to:

Accepted Answer

Show logical dependencies without consuming time or resources

Answer

Dummy activities in AOA diagrams are zero-duration, zero-resource arrows that represent required logical dependencies between activities.
