PMI-SP Activity Sequencing 2

Question 1

A project scheduler is modeling a situation where Activity B cannot start until 5 days after Activity A starts. Which type of dependency relationship best represents this?

Accepted Answer

Start-to-Start with 5-day lag

Answer

A Start-to-Start (SS) relationship with a 5-day lag means B cannot start until 5 days after A starts.

Question 2

Which sequencing method uses arrow diagrams where arrows represent activities and nodes represent events?

Accepted Answer

Arrow Diagramming Method (ADM)

Answer

The Arrow Diagramming Method (ADM) uses arrows for activities and nodes for events, unlike PDM which uses nodes for activities.

Question 3

A scheduler discovers that two activities were linked with a mandatory dependency due to a contractual requirement, not a physical one. How should this be classified?

Accepted Answer

Mandatory external dependency

Answer

A contractual requirement imposed by an external party creates a mandatory external dependency.

Question 4

In a network diagram, Activity X has three predecessors: A (FS), B (FS+3 days lag), and C (FS-2 days lead). If A finishes on Day 10, B finishes on Day 8, and C finishes on Day 12, when is the earliest X can start?

Accepted Answer

Day 11

Answer

X's early start = max(10+0, 8+3, 12-2) = max(10, 11, 10) = Day 11.

Question 5

Which term describes a dependency that originates within the performing organization's own control or project scope?

Accepted Answer

Internal dependency

Answer

Internal dependencies are relationships between project activities that are within the control of the project team.
