PMBOK Project Schedule Management Questions and Answers Flashcards

Which process in PMBOK schedule management involves determining the order and logical relationships among scheduled activities?

Answer: Sequence Activities

The Sequence Activities process identifies and documents relationships among project activities, establishing the logical order of execution.

What is a Lead in project scheduling?

Answer: The amount of time a successor activity can start before its predecessor finishes

Lead is the amount of time by which a successor activity can be advanced relative to a predecessor activity, effectively overlapping work.

Resource leveling in schedule management is used primarily to:

Answer: Resolve resource over-allocations, often at the cost of extending the schedule

Resource leveling adjusts start and finish dates to balance resource demand against supply, which can extend the project schedule to resolve over-allocations.

What is the formula for calculating Total Float?

Answer: Late Finish minus Early Finish (or Late Start minus Early Start)

Total Float equals the Late Finish minus Early Finish (or equivalently, Late Start minus Early Start) for any given activity in the network.

Which tool is used during Control Schedule to compare actual schedule performance against the schedule baseline?

Answer: Schedule variance analysis

Schedule variance analysis compares baseline dates to actual or forecasted dates to identify deviations and determine if corrective action is needed.

In PERT (Program Evaluation and Review Technique), the expected duration formula using optimistic (O), most likely (M), and pessimistic (P) estimates is:

Answer: (O + 4M + P) / 6

PERT calculates expected duration as (O + 4M + P) / 6, giving four times the weight to the most likely estimate to produce a weighted average.
