PMI Project Planning & Scheduling 2

Question 1

Which scheduling technique uses probabilistic time estimates to account for uncertainty in activity durations?

Accepted Answer

Program Evaluation and Review Technique (PERT)

Answer

PERT uses three-point estimates (optimistic, most likely, pessimistic) to handle schedule uncertainty and calculate expected durations.

Question 2

A project manager applies a 15% buffer to all activity estimates before finalizing the schedule. This practice most directly indicates a failure to apply which principle?

Accepted Answer

Parkinson's Law awareness

Answer

Padding estimates inflates the schedule and reflects poor awareness of Parkinson's Law, where work expands to fill the time allotted.

Question 3

When two activities must finish before a third can start, this represents which type of logical relationship?

Accepted Answer

Finish-to-Start (FS)

Answer

Finish-to-Start is the most common dependency, where the successor activity cannot begin until the predecessor activity is complete.

Question 4

Which document formally authorizes work packages and assigns responsibility to performing organizations in the project plan?

Accepted Answer

Work Package Authorization

Answer

Work Package Authorization documents formally authorize work to begin and assign accountability for deliverables within the project plan.

Question 5

During schedule development, the project manager identifies that a resource is assigned 150% capacity during week 3. The BEST corrective action is to:

Accepted Answer

Apply resource leveling or resource smoothing

Answer

Resource leveling adjusts start and finish dates based on resource constraints to resolve overallocation without necessarily crashing the schedule.
