Even if the beta distribution assumption holds, pert assumes that the probability distribution of the project completion time is the same as the that of the critical path because other paths can become the critical path if their associated activities are delayed, pert consistently underestimates the expected project completion time.

Cpm stands for critical path method which was developed by dupont company and applied first to the construction projects in the chemical industry though both pert and cpm techniques have similarity in terms of concepts, the basic difference is, pert is used for analysis of project scheduling problems. The management operation system technique (most) invented in 1961, replaces pert and cpm on construction projects and in program management since its inception, most has gained popularity and is now widely used in both large and small construction.
Software programs on programme evaluation and review techniques (pert) and critical path method (cpm) techniques have been developed to analyze the major overhauling of modern bulldozers. Module 9 project planning and network analysis lesson 19 rules for drawing network analysis 191 introduction a fundamental ingredient in both pert and cpm is the use of network systems as a means of graphically depicting a project.
