PMI-SP Activity Sequencing 5

Question 1

A project manager is sequencing activities and realizes that Activity Y cannot finish until Activity X has been started. Which PDM relationship applies?

Accepted Answer

Start-to-Finish (SF)

Answer

Start-to-Finish (SF) means the successor (Y) cannot finish until the predecessor (X) has started.

Question 2

During activity sequencing, the project team decides to sequence installation of electrical systems before plumbing based solely on crew availability preferences, even though either could go first physically. This is an example of:

Accepted Answer

Discretionary dependency

Answer

Discretionary dependencies are established based on knowledge of best practices or team preferences, not physical constraints.

Question 3

Which tool used during Sequence Activities helps a scheduler visualize and confirm that all logical relationships are complete and there are no open-ended activities?

Accepted Answer

Project schedule network diagram

Answer

The project schedule network diagram reveals open ends (activities with no predecessors or successors) that indicate incomplete logic.

Question 4

A schedule network shows Activity P with Total Float of 0 and Activity Q with Total Float of 4 days. Which statement is correct?

Accepted Answer

Activity P is on the critical path; Activity Q has 4 days of flexibility

Answer

Zero total float means Activity P is on the critical path; Activity Q can be delayed up to 4 days without affecting the project end date.

Question 5

When using the Precedence Diagramming Method, what does a 'merge' activity represent?

Accepted Answer

An activity that receives inputs from multiple predecessor activities

Answer

A merge activity is one that has multiple predecessors — multiple paths converge into a single activity.
