28. The program evaluation and review technique (PERT) method of

scheduling differs from the critical path method (CPM) because the

PERT method:

a. Uses weighted averages of activity durations to calculate project du-

ration.

b. Uses ‘‘dummy’’ activities to represent logic ties.

c. Uses ‘‘free float’’ instead of ‘‘total float’’ in the schedule calculations.

d. Uses bar charts instead of logic diagrams to portray the schedule.
