CPM projects the activity duration in a deterministic What is the probability that the project will be completed before the late-payment deadline? Select one: a. It is ideal for projects where the duration of tasks is uncertain. Difference between PERT and CPM PERT 1. to monitor large and complex projects. PERT, on the other hand, employs a probabilistic model. Jun 10, 2018 · #YouTubeTaughtMe Updated video: https://youtu. It uses network diagram 4. CPM, on the other hand, is a backward-looking method, meaning that it is used to monitor and control the progress of a project. In this article, we will explore the differences between CPM and PERT in detail. b) CPM assumes activity durations can vary. PERT uses one time estimate. to plan large and complex projects. near 1. In simple words, in PERT network interest is focused upon start or completion of events and not on activities themselves. 1 Introduction to CPM / PERT Techniques 2. com/i. The fundamental difference between PERT and CPM is that PERT uses three time estimates for each activity while CPM makes the assumption that activity times are known with certainty. C. It also does not manage the scheduling of all types of resource allocation. It is deterministic 5. So it is deterministic. FALSE Slack is the amount of time an activity can be delayed without delaying the entire project. , Which is not a significant Differences between PERT and CPM CPM is a statistical technique used to control cost and time, often found in construction project management. PERT is a technique of planning and control of time. PERT optimizes resources by identifying the critical path of tasks and allocating resources to these tasks. Over the years, PERT has evolved to include a number of additional features and capabilities. PERT assumes that activity durations are known c. Apr 7, 2023 · Welcome To Class Series. Mar 22, 2021 · Some of the major differences between PERT and CPM are given below: PERT is a visual project management technique where we plan, schedule, organize, coordinate and control uncertain activities. PERT is a variant of Critical Path Analysis that takes a more skeptical view of the time needed to complete each project stage. The main difference between PERT and CPM is that. PERT is More accurate than CPMb. O PERT assumes that activity durations are known. D) CPM assumes activity durations can vary E) PERT employs three time estimates for each activity 27) The ES of an activity that has only one predecessor is simply The primary purpose of PERT and CPM is to identify the critical path and determine the minimum duration required to complete a project.
