DPO Project Planning & Scheduling 2

Question 1

In a project network diagram, which path determines the minimum project duration?

Accepted Answer

The longest path through all activities

Answer

The critical path is the longest sequence of dependent activities and sets the earliest possible project completion date.

Question 2

What does 'total float' represent in network scheduling?

Accepted Answer

The amount of time an activity can be delayed without delaying the project end date

Answer

Total float is the maximum time an activity can be delayed without pushing the overall project finish date.

Question 3

A Finish-to-Start (FS) dependency with a lag of 3 days means:

Accepted Answer

Activity B cannot start until 3 days after Activity A finishes

Answer

A positive lag on an FS relationship adds a mandatory waiting period between the predecessor finishing and the successor starting.

Question 4

During DP project planning, a vessel mobilization activity has Early Start day 5 and Late Start day 9. What is its total float?

Accepted Answer

4 days

Answer

Total float equals Late Start minus Early Start (or Late Finish minus Early Finish), so 9 − 5 = 4 days.

Question 5

Which dependency type allows a successor activity to begin before its predecessor is complete?

Accepted Answer

Finish-to-Start (FS) with negative lag (lead)

Answer

A negative lag (lead) on an FS relationship allows the successor to start before the predecessor finishes, effectively overlapping activities.
