The program evaluation and review technique (PERT) involves charts that display scheduled tasks for project completion. This type of flow chart is a common method used by project managers, and is part of the critical path analysis that focuses on essential tasks for project completion. Project managers often design PERT charts for specific parts of complex projects. Each chart begins with one node that branches out into networks of activities, emphasizing relationships among tasks. PERT has both advantages and disadvantages.
Advantage: Large Project PlanningA PERT chart makes planning large projects easier, according to the University of Pittsburgh School of Information Sciences. It answers three key questions about each activity that help managers identify relationships between tasks and task dependencies. These questions involve how long it will take to complete an activity, and which other activities must occur immediately before and immediately after this activity for effective project completion. PERT is a good way of making these relationships visible in a diagram.
The critical path includes all activities that cannot be delayed without affecting the project completion date. PERT makes the critical path visible, as explained by the University of Virginia. All tasks not on the critical path can have some slack time without affecting project completion time. When the project manager must delay one task to allocate more time to another, the critical path makes clear which tasks cannot be delayed.

What are the limitations of PERT?
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.
What is the disadvantage of cpm?
There are several disadvantages of CPM or Critical Path Method. A few of the disadvantages are CPM is more complicated and complex, doesn't handle scheduling, and you can't estimate completion times.

What is the advantages of a pert chart?
Advantages of a PERT chart is that it's a great mean for visualizing and communicating progress on projects. They usually help the Project Manager to better manage the project.

What is cpm and pert?
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.
What is PERT charts?
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.
Is Cpm software available on the internet?

What is the different between critical path method and program evaluation and review technique?
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.
