PMI-SP Critical Path Method 4

Question 1

A project scheduler is analyzing a network and finds that Activity X has Free Float of 0 but Total Float of 5 days. What does this mean?

Accepted Answer

Delaying Activity X will not delay its successor but could delay the project

Answer

Zero free float means any delay impacts the next activity, but positive total float means the project end date is not immediately threatened.

Question 2

When using CPM, which output is MOST useful for identifying where to apply schedule compression effort?

Accepted Answer

Network diagram with float values

Answer

A network diagram displaying float values clearly shows which activities are on the critical path (zero float) and where compression will shorten the schedule.

Question 3

In Activity-on-Node (AON) notation, which of the following represents a dependency relationship?

Accepted Answer

An arrow connecting two activity boxes

Answer

In AON (Precedence Diagramming Method), boxes represent activities and arrows between boxes represent logical dependencies.

Question 4

A project has a planned duration of 90 days. After crashing two critical path activities, the duration drops to 82 days at a cost of $4,000. What is the crash cost per day?

Accepted Answer

$500

Answer

Crash cost per day = Total crash cost ÷ Days saved = $4,000 ÷ 8 = $500 per day.

Question 5

Which statement best describes 'float consumption' during project execution?

Accepted Answer

Actual delays on non-critical activities reduce available float

Answer

As non-critical activities experience delays, their float is consumed, potentially making them critical or creating negative float.
