P E R T is the acronym for Product Evaluation Review Technique. C P M signifies Critical Path Method.
Both are used for planning and scheduling. Steps to create both networks are similar
Critical Path Method (CPM) - A schedule network analysis technique used to identify the schedule flexibility and the critical path of the project schedule network diagram.
CPM -Critical Path Method
Program Evaluation and Review Technique: is a network technique that uses three times estimates for each activity in a project. PERT is probalistic, whereas CPM is deterministic.
A PERT CPM network should primarily serve as a tool for understanding reports and schedules, as it visually represents project tasks, their dependencies, and timelines. By using the network to clarify and analyze project data, stakeholders can effectively manage resources and identify critical paths. Conversely, reports and schedules should be derived from the insights provided by the PERT CPM network, ensuring that they accurately reflect project progress and timelines. This approach enhances decision-making and project control.

PERT/CPM suffers mainly suffers from a main issue is that when the network becomes very big (eg containing hundreds of activities) it becomes almost impossible to handle (printing, reading, etc...). Comparing CPM to CCPM we discover that CCPM has a better utilization of project resources, among other advantages.

Program Evaluation and Review Technique (PERT) lays the foundation of the network diagram or process by which the program will be completed. The Critical Path Method (CPM) is used within PERT to determine a critical path for a project within a program or the program itself if all the duration information is known for the program. CPM is a subset of PERT.
