Detailed explanation-1: -CPM is activity oriented i.e. CPM network is built on the basis of activities. PERT is event oriented. CPM is a deterministic model i.e. it does not take into account the uncertainties involved in the estimation of time for execution of a job or an activity.

Detailed explanation-2: -Activity-oriented approaches lay emphasis on the understanding of dis-turbances and unforeseen tasks and to the analysis of user or operator responses.

Detailed explanation-3: -The critical path method (CPM) is a step-by-step project management technique for process planning that defines critical and non-critical tasks with the goal of preventing project schedule problems and process bottlenecks.

Detailed explanation-4: -PERT or program evaluation and review technique, is an event oriented method of network planning. In it, the emphasis is focused on the start and completion of events rather than on activities. In the PERT network, the event falls in logical sequence.

Detailed explanation-5: -Following are the basic differences between PERT and CPM: Program Evaluation Review Technique is event-oriented, while CPM is activity oriented. Activity times in CPM technique is related to costs, but this is not the case with PERT as it is event oriented.
