# What Are The Advantages Of PERT And CPM?

## What are the assumptions in CPM?

A project can be sub-divided into a set of predicable, independent activities.

The precedence relationships of project activities can be completely represented by a non-cyclical network graph in which each activity connects directly into its immediate successors..

Disadvantages of Critical Path Method (CPM): In CPM, it is difficult to estimate the completion time of an activity. The critical path is not always clear in CPM. For bigger projects, CPM networks can be complicated too. It also does not handle the scheduling of the resource allocation.

## Why would you use a PERT chart?

PERT charts are generally used before a project begins to plan and determine the duration of each task—so they don’t have to show the actual dates of your project. They also do a better job of showing whether certain tasks need to be completed in order or whether they can be completed simultaneously.

## What is pert formula?

PERT calculates a weighted average as the PERT estimate by using the formula : Pert Estimate = (Optimistic + (4 X Most Likely) + Pessimistic)/6.

## What is the full form of PERT and CPM?

This video tutorial explains you the difference between Project Evaluation and Review Technique (PERT) and Critical Path Method (CPM).

## What is the concept of CPM?

Cost per thousand (CPM), also called cost per mille, is a marketing term used to denote the price of 1,000 advertisement impressions on one web page. If a website publisher charges \$2.00 CPM, that means an advertiser must pay \$2.00 for every 1,000 impressions of its ad.

## What are the limitations of PERT and CPM?

Another of the limitations of PERT and CPM is that the larger the project, the more complicated the diagram. Above a certain level of complexity, all the lines you map out start to look incomprehensible rather than enlightening.

## What is the difference between a PERT and Gantt chart?

Essentially, a Gantt chart is a bar chart that lays out project tasks and timelines linearly. … A PERT chart, on the other hand, is structured as a flow chart or network diagram that displays all the project tasks in separate boxes and connects them with arrows to clearly show task dependencies.

## Why do we use CPM?

The critical path method (CPM) is a project modeling technique that’s used by project managers to find the important deadlines and deliver a project on time. … To find this, project managers use the CPM algorithm to find the least amount of time necessary to complete each task with the least amount of slack.

## What are the advantages of PERT?

The advantages of PERT: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.More items…•

## What are the differences between 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.

## Is PERT or CPM better?

PERT is a technique of planning and control of time. Unlike CPM, which is a method to control costs and time. … PERT technique is best suited for a high precision time estimate, whereas CPM is appropriate for a reasonable time estimate. PERT deals with unpredictable activities, but CPM deals with predictable activities.

## What is meant by CPM?

CPM (cost per mille) is a paid advertising option where companies pay a price for every 1,000 impressions an ad receives. An “impression” refers to when someone sees a campaign on social media, the search engines or another marketing platform.

## What are the uses of PERT and CPM?

A deterministic model is used in CPM. While PERT uses a probabilistic model. PERT is generally used in Research and development projects. CPM is generally used in a Construction project, Projects of repeatable nature like residential construction, rollouts, etc.

## What is PERT CPM chart?

A PERT chart is a project management tool that provides a graphical representation of a project’s timeline. The Program Evaluation Review Technique (PERT) breaks down the individual tasks of a project for analysis.
