CPM (Critical Path Method)
-
CPM is an activity-oriented network.
-
It focuses on activities that make up a project and identifies the critical path — the sequence of activities that determines the project duration.
-
Activities have well-defined, deterministic durations (known in advance).
-
Used for projects like construction, maintenance, manufacturing — where activity durations are predictable.
Additional InformationPERT (Program Evaluation and Review Technique)
-
PERT is an event-oriented network, not activity-oriented.
-
It focuses on events (milestones) and the probabilities of reaching them.
-
It deals with uncertain or variable durations, using probabilistic time estimates (optimistic, most likely, pessimistic).
-
Used for research, R&D, or projects with uncertainty in task durations.
