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

    Answer: Program Evaluation and Review Technique (PERT)

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

  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?

    Answer: Parkinson's Law awareness

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

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

    Answer: Finish-to-Start (FS)

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

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

    Answer: Work Package Authorization

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

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

    Answer: Apply resource leveling or resource smoothing

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

  6. A schedule baseline differs from the project schedule in that the baseline:

    Answer: Is the approved version used as a comparison for performance measurement

    The schedule baseline is the approved version of the schedule that serves as a fixed reference point for measuring and reporting schedule performance.

  7. The formula for calculating PERT expected duration using three-point estimates is:

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

    The PERT beta distribution formula weights the most likely estimate four times more than the optimistic or pessimistic estimates: (O + 4M + P) / 6.
