PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are two popular techniques used in project management to analyze and plan the tasks involved in completing a project. Both techniques involve creating a network diagram that represents the tasks in a project and their dependencies.
PERT was originally developed by the U.S. Navy in the 1950s to manage the development of the Polaris missile. It is a flexible technique that allows for the incorporation of uncertainty and allows for the calculation of expected completion time based on optimistic, pessimistic, and most likely estimates for each task. PERT is used in projects where the tasks and their dependencies are not fully known in advance and where the project schedule is subject to change.
CPM, on the other hand, was developed by DuPont in the late 1950s and is used in projects where the tasks and their dependencies are well-defined and the project schedule is not subject to change. In CPM, the longest path through the network diagram is identified as the critical path, and the total project duration is equal to the length of the critical path. Any delays on tasks on the critical path will delay the entire project.
Both PERT and CPM are useful tools for managing projects and analyzing the tasks involved. PERT is particularly useful in projects where there is uncertainty, while CPM is more suitable for projects where the tasks and dependencies are well-defined. Both techniques involve creating a network diagram, estimating the duration of each task, and analyzing the relationships between tasks to identify potential bottlenecks or areas for optimization. By using PERT or CPM, project managers can better understand the tasks involved in a project and plan for their completion.
How does PERT and CPM help in project management?
Activity-on-Arrow Example In an AOA project network we can represent activities by arrows. CPM is a deterministic model. Once you are done with listing, designing, and evaluating the tasks, you now have to identify the tasks that form critical paths. This compensation may impact how and where products appear on this site including, for example, the order in which they appear. What is PERT Formula? Critical path method CPM is a resource-utilization algorithm for scheduling a set of project activities. The techniques help managers to optimize the longest time duration in order to minimize the total project cost and time.

A distinction is present between critical and non-critical activities. CPM goals are to check time-bound issues and process that causes blockage in the project. But use of these tools does not guaranty the desired outcome due to bad management problems, natural calamities, strikes by labors etc. Predecessor Task Task that must be completed before another task can be completed. Task or Event A divisible, definable unit of work related to a project, which may or may not include subtasks.

How to find the critical path In order to find the critical path of a project task, the duration of critical and non-critical tasks must be considered. Alternatively, the estimation can also be done by predicting the earliest date of start and finish together with the late start and finish timings. As each of these, in turn, decomposed or broken down into its component tasks, each component receives a number comprised of its parent number plus a unique number of its own. PERT Program Evaluation Review Technique CPM Critical Path Method An analytical project management approach is used to determine the precise time taken by the team to successfully complete the project by managing undefined activities. Using the Considering the formula above, it can be represented in this way Therefore 3 hours is the estimated amount of time your supplies for your party will be delivered using the average of the pert formula CPM Formula Explained in Project Management The The method is based on the concept of the longest path through a network of activities.

PERT vs CPM
Project management and review methods like PERT and CPM. These are early start earliest time a project can be started , late start latest time to start a project , early finish earliest completion of a project and late finish latest time to complete a project without causing delays. Using a methodology or system life cycle analysis, design and implementation steps as a guide, the project is divided into its major steps. What is the use of Pert in project management? CPM is used where activities are definable and measurable and minimum overall cost is of the utmost importance. The students will however notice that this time is shorter than the total time listed under Table 1 which will be 45 days.

. In a CPM chart, the critical path is indicated. The first test was made in 1958, when CPM was applied to the construction of a new chemical plant. CPM does not handle unpredictable activities as well as PERT, but it is solid when the project has a more predictable nature. Decide which activities must precede and which must follow others. It is best suited for repetitive project activities. The arrows connect the nodes or Benefits of Using PERT and CPM It should be clear what the advantages of using PERT CPM are.

It grew out of work at DuPont and has always been closely tied to the construction industry especially in huge civil construction projects. It is an activity-oriented approach method. This path is referred to as the Critical Path, and it represents the minimum amount of time needed to complete the project. Learn more PERT vs. It is also a method used to identify the activities that are most likely to delay the project. The chart is widely used as a project management tool.

Meaning of CPM Critical Path Method or CPM is a well-known project modelling technique in project management. Network Diagrams and Approaches The first step in a PERT or CPM network is to divide the entire project into significant activities in accordance with the work breakdown structure. CPM is that technique of project management which is used to manage only certain i. Each task is connected to its successor tasks in this manner forming a network of nodes and connecting lines. Benefits of CPM In project management, the Critical Path Method CPM is a tool used to determine the sequence of project activities and the duration of each activity. In some cases it may be necessary to label the period columns as period 1, period 2, and so on. The Critical Path Method or CPM has been used in many industries starting from defence, construction, software, aerospace, etc.
