    Answer: CPM and PERT use different activity time estimates.

    Explanation:

    Program (Project) Management and Review Technique (PERT) is appropriate when the project time needed to complete different activities are unknown while the Critical Path Method or CPM is fitted for recurring projects in nature. PERT deals with activities that are not predictable but CPM deals with repetitive activities. PERT focuses/concentrates on time while CPM focuses on time-cost & trade-off. Also, PERT requires three-time estimate while CPM requires one-time estimate. PERT uses a probabilistic model and on the other hand, CPM uses a deterministic model. In PERT, a technique of planning and controlling time is used but CPM uses a technique to control cost and time.

    The correct answer is letter "D": CPM integrates time and cost performance while PERT is based solely on time performance.

    Explanation:

    The Project Management and Review Technique also called PERT is used to plan and control the time of uncertain activities during the development of a project. The PERT is an event-oriented technique. The Critical Path Method or CPM is a statistical technique used to control the cost and time of well-defined activities of a project. The CPM is activity-oriented.
