PERT and CPM are the tools that are used to manage and schedule the events and activities of the project. Both of these tools are used to manage or control time. These tools also maintain the resources and many other aspects of the project. To achieve the project goals these tools are very helpful. Both the tools are network-based which shows the flow
sequence of the events and the activities. In this article, we will discuss in detail the difference between PERT and CPM. The program evaluation and review Technique (PERT) is suitable for the projects where completion time of projects is unknown. And (CPM) Critical path method is adopted where the completion time of the project is fixed. CPM is used in the construction industry. In the construction industry, there are many types of major projects.
Mostly these projects have to be completed in a certain time period or as fast as can. There are many big projects in civil construction like road projects, Hydroelectric projects, and many other big constructions of conventional sources of
energy. These methods have a common approach to designing the network to find its critical path. There are used for the successful completion of the project so, they connect with each other. But there are many differences between Pert and CPM which we will discuss in this article.
What is PERTPERT stands for Program Evaluation and Review Technique. This technique is used to plan and identify the time taken for the completion of particular activity and event of the project. In this planning technique organizing, coordinating, scheduling, and controlling uncertain activities takes place. Charts are created in PERT which shows the graphical representation of the events and the activities. This technique studies and shows the least time is taken to complete the activity and minimum time for the completion of the projects. This technique uses time as a variable. The part first part is to break the project into the events and the activities. After the breaking of the project next step is to make proper sequence is managed. Then time is considered for each event and the activity and then find a critical path. History of PERTUs Navy special projects office Missile system division developed pert back in 1957. Pert is developed during the production of the UGM-27 missile. And then it is implemented in the winter Olympics from 1965 to 1968. The main aim of this technique is to reduce the cost and time of the project. Advantages of PERT
What is CPMCPM stands for Critical Path Method. It is a modeling technique of the project in which scheduling of project activities is done in an effective way. This model finds the maximum time taken for an activity. In CPM it Is predicted that the earliest and latest start time is possible for every activity. As the name indicates the critical path is identified because if an activity delays all activities have to be suffered. In CPM all the activities are listed which have to perform or complete for the project completion. After that, the sequence is maintained because many activities are dependent on previous activities. Simply means some actives are on starts after the completion of the previous activity. And then estimates the time required for the completion of each activity. after that a critical path is selected. The critical path is the longest sequence of the activities that have to complete on time. Advantages of CPM
Difference Between PERT and CPM
ConclusionBoth of these techniques are very important for project management. PERT and CPM both are time management techniques. In this current time is very valuable. All of us know that time is money. With the help of these techniques, we can easily look at the progress of the project with respect to time and cost. CPM is very helpful to minimize the cost of the project in an effective way. This is all about the difference between PERT and CPM. We hope you understand the concept.

It is a modeling technique of the project in which scheduling of project activities is done in an effective way What is the main difference between PERT and CPM?PERT vs CPM. What is the main difference between PERT and CPM quizlet?The basic difference between PERT and CPM is that PERT requires three time estimates of activity completion time, whereas CPM uses only a single estimate. The ES of an activity that has only one predecessor is simply the EF of that predecessor.
What is the similarity between PERT and CPM?Both PERT and CPM rely upon the analysis of four primary schedule components, being: A list of all activities required to complete the project. The expected time that each activity will take to complete. The dependencies between each activity.
What is the biggest difference between a PERT chart and a CPM chart in project management?The number of time estimates is the biggest difference between the CPM and PERT diagrams. The PERT has an optimistic time, a pessimistic time, and a most likely time. In addition, the PERT diagram has the time estimates on the arrow vice the node as in the CPM diagram.
