PERT and CPM are both project management techniques. PERT stands for Project Evaluation and Review Technique, while CPM stands for Critical Path Method.  PERT is a visual technique that helps project managers plan, schedule, and control uncertain activities. PERT focuses on time planning and control, and incorporates three time estimates for each activity: optimistic, pessimistic, and most likely.  CPM is a statistical technique that helps project managers plan, schedule, and control well-defined activities. CPM is used to manage time and cost. CPM relies on a single, deterministic estimate... Show more

PERT and CPM are both project management techniques. PERT stands for Project Evaluation and Review Technique, while CPM stands for Critical Path Method. 

PERT is a visual technique that helps project managers plan, schedule, and control uncertain activities. PERT focuses on time planning and control, and incorporates three time estimates for each activity: optimistic, pessimistic, and most likely. 

CPM is a statistical technique that helps project managers plan, schedule, and control well-defined activities. CPM is used to manage time and cost. CPM relies on a single, deterministic estimate for each activity duration. 
 

PERT and CPM can be used together. For example, PERT can be used to outline the overall project path for building a home. If the house is needed sooner than expected, CPM can be used to identify the critical path and reduce the overall time required for the project.
