Unit VIII: Business Statistics and Operations Management

Both the techniques use similar technology and same purpose
The use of PERT and CPM techniques is made in both planning and controlling of the project:
CPM was the method developed by DuPont for scheduling and managing chemical plant. projects in 1957.
PERT was specifically developed by the U.S. Navy for the Polaris submarine missile program in 1958.

Feature	PERT	CPM
Time Estimates	Uses three estimates (optimistic, pessimistic, most likely)	Uses a single, fixed time estimate
Uncertainty	Designed to handle uncertainty	Assumes fixed, deterministic durations
Focus	Focuses on probabilistic scheduling	Focuses on critical path and project duration
Use Case	Best for uncertain, complex projects (e.g., R&D, technology)	Best for predictable projects (e.g., construction)
Critical Path	Identifies critical path, but the main focus is on time estimates	Strong emphasis on identifying and managing the critical path
Risk Management	Considers uncertainty and variability	Assumes known durations, less focus on risk
