Question 1

Which scheduling technique uses three time estimates (optimistic, pessimistic, most likely) to calculate expected activity durations?

Accepted Answer

Program Evaluation and Review Technique (PERT)

Answer

PERT uses three-point estimates (optimistic, most likely, pessimistic) to calculate a weighted average expected duration for each activity.

Question 2

A project schedule network diagram shows activities A→C→E and A→B→D→E. Activity durations are: A=3, B=4, C=2, D=3, E=5. What is the critical path duration?

Accepted Answer

12 days

Answer

Path A→B→D→E = 3+4+3+5 = 15 days; Path A→C→E = 3+2+5 = 10 days; the critical path A→B→D→E is 15 days.

Question 3

What does the term 'free float' mean in project scheduling?

Accepted Answer

The amount of time an activity can be delayed without delaying the early start of any successor activity

Answer

Free float is the amount of time an activity can be delayed without affecting the early start of any immediate successor activity.

Question 4

Which resource optimization technique adjusts start and finish dates without changing the critical path, accepting the resource peaks and valleys that result?

Accepted Answer

Resource smoothing

Answer

Resource smoothing adjusts float activities to meet resource constraints while keeping the critical path and project end date unchanged.

Question 5

A schedule baseline differs from the project schedule primarily because the baseline is:

Accepted Answer

The approved version used for comparison and performance measurement

Answer

The schedule baseline is the formally approved version of the project schedule used as a benchmark for measuring schedule performance.
