Are PERT/CPM methods planning or control techniques? * Network Planning Techniques, : PERT CPM Critical Path Method Program Evaluation & Review Technique Project management technique that shows the time taken by each component of a project, and the total time required for its completion. step-by-step project management technique for process planning that defines - critical and non-critical tasks with the goal of preventing time-frame problems. ideally suited to projects consisting of numerous activities that interact in a complex PERT breaks down the project into events and activities, and lays down their proper sequence, relationships, and duration in the form of a network. manner Difference between CPM & PERT CPM PERT . CPM works with fixed PERT works with deterministic time probabilistic time CPM is useful for repetitive PERT is useful for non and non complex projects with repetitive and complex projects a certain degree of time with uncertain time estimates. estimates. . CPM includes time-cost trade . PERT is restricted to time off. variable, CPM- for construction projects. PERT- used for R&D programs Abbreviation PERT - Project Evaluation and Review Technique CPM - Critical Path Method Focus PERT The main focus of PERT is to minimise the time required for completion of the project CPM - The main focus of CPM is on a trade-off between cost and time, with a major emphasis on cost- cutting
