Its the abbreviation of Program Evaluation and Review Technique / Critical Path Method.
The critical path method (CPM) is a project modeling technique developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley, Jr. of Remington Rand.Kelley and Walker related their memories of the development of CPM in 1989. Kelley attributed the term "critical path" to the developers of the Program Evaluation and Review Technique which was developed at about the same time by Booz Allen Hamilton and the US Navy. The precursors of what came to be known as Critical Path were developed and put into practice by DuPont between 1940 and 1943 and contributed to the success of the Manhattan Project.
CPM is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of mathematical analysis. Although the original CPM program and approach is no longer used, the term is generally applied to any approach used to analyze a project network logic diagram.
PERT is a method to analyze the involved tasks in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project.
PERT was developed primarily to simplify the planning and scheduling of large and complex projects. It was developed for the U.S. Navy Special Projects Office in 1957 to support the U.S. Navy's Polaris nuclear submarine project. It was able to incorporate uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in projects where time, rather than cost, is the major factor. It is applied to very large-scale, one-time, complex, non-routine infrastructure and Research and Development projects. An example of this was for the 1968 Winter Olympics in Grenoble which applied PERT from 1965 until the opening of the 1968 Games.
This project model was the first of its kind, a revival for scientific management, founded by Frederick Taylor (Taylorism) and later refined by Henry Ford (Fordism). DuPont's critical path method was invented at roughly the same time as PERT.

What is a PERT Chart?
A PERT (Program Evaluation and Review Technique) chart is a graphic representation of a project schedule, showing the sequence of tasks, which tasks can be performed simultaneously, and the critical path of tasks that must be completed on time in order for the project to meet its completion deadline. A Gantt chart is another representation of a project schedule, but specifically uses a bar chart.
When is a PERT diagram useful for systems projects?
PERT diagrams are useful in communicating information about projects through easy visual charts.
Is Autonomics is the study of designing and positioning workplace equipment?
No, that is Ergonomics. Autonomic refers to something that happens involuntarily or spontaneously and is often used in connection with that pert of the nervous system that is not usually under conscious control.

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?
Yes, CPM software is available on the internet. 3d2f.com/tags/cpm/pert/ is a website with free CPM softward downloads. Yes, CPM software is available on the internet. There are many different companies that provide the software at different prices. You can look at the various places to see what requirements you need.

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.
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.
