What is the purpose of PERT?
Program Evaluation and Review Technique (PERT) is a method used to examine the tasks in a schedule and determine a Critical Path Method variation (CPM). It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project.
Why do we use PERT and CPM?
PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.
What is PERT and how can we use it?
A PERT chart, sometimes called a PERT diagram, is a project management tool used to schedule, organize and coordinate tasks within a project. It provides a graphical representation of a project’s timeline that enables project managers to break down each individual task in the project for analysis.
What is requirement of PERT?
All events need to be completed in sequence. PERT activity – The performing of a task, recorded by the time taken to do so and the resources required. PERT sub-activity – The breaking-down of activities within an activity. Optimistic time – As the name suggests, the minimum time required to complete an activity.
What is PERT and its advantages?
It provides a graphical display of project activities that helps the users understand the relationships among the activities. It is the ideal technique for tactical level planning and operational level control of projects. It is effective in planning single project activities in any type of industry.
Is PERT or CPM better?
To achieve the end goal of a project on time, PERT and CPM are two project management techniques that every management should implement….PERT vs CPM.

What is PERT example?
A PERT chart uses circles or rectangles called nodes to represent project events or milestones. These nodes are linked by vectors or lines that represent various tasks. For example, if an arrow is drawn from Task No. 1 to Task No.
How is the PERT used in project management?
In project management, Project Evaluation Review Technique or PERT is used to identify the time it takes to finish a particular task or activity. It is a system that helps in proper scheduling and coordination of all tasks throughout the project.
What are the advantages and disadvantages of Pert?
Advantage: Answering the What-If’s A PERT chart enables you to create milestones for your project. During the time between each milestone, you can use the chart to identify any possible outcomes or obstacles that your project may face. This means you can quickly address them, or prepare for them, to help your project stay on track.
What do you need to know about a PERT Chart?
A true PERT chart involves a 3-point estimation technique, which assigns three possible duration estimates to each task: This estimation technique allows project managers to calculate a more realistic project schedule. And makes it easier to calculate “what-if” scenarios.
Where did the concept of Pert come from?
It’s actually a military term that was developed by the Polaris submarine research team way back in 1959 when they were trying to create a nuclear weapons program. Since then, many industries have adopted this process to help them effectively manage their marketing strategies, their business projects and many other kinds of projects.
