CPM is a statistical technique of project management in which planning, scheduling, organising, coordination and control of well-defined activities take place. 2. PERT is
a technique of planning and control of time
. Unlike CPM, which is a method to control costs and time.
What is the basic difference between PERT and CPM quizlet?
What is the basic difference between PERT and CPM? The basic difference between PERT and CPM is that
PERT requires three time estimates of activity completion time
, whereas CPM uses only a single estimate. The ES of an activity that has only one predecessor is simply the EF of that predecessor.
What is the main difference between CPM and PERT?
| 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. | Orientation type |
|---|
What is the difference between PERT and critical path?
The main difference between PERT and Critical Path is
knowing how long a given task will take
. With PERT, task durations are variable, hence the need to predict time using a model. Critical Path is more useful for projects where task length is easy to predict, such as a construction project or a large conference.
What does CPM PERT mean?
PERT project management
and CPM are two famous managerial techniques. PERT is an abbreviation of the Program Evaluation and Review Technique. CPM is an abbreviation of the Critical Path Method.
What are the similarities and differences between PERT and CPM?
| BASIS FOR COMPARISON PERT CPM | Focuses on Time Time-cost trade-off | Estimates Three-time estimates One time estimate | Appropriate for High precision time estimate Reasonable time estimate | Management of Unpredictable Activities Predictable activities |

What is the use of PERT and CPM?
PERT and CPM are tools used
for managing the construction project activities
and if followed thoroughly, the construction project can be completed within the time limit and within the cost.
Which is not one of the limitations of PERT CPM?
Which of the following is NOT a limitation of PERT?
Only one time estimate can be used for each activity
. Slack is the amount of time an activity can be delayed without delaying the entire project. PERT, but not CPM, has the ability to consider the precedence relationships in a project.
What are the three phases involved in the management of a large project?
- Planning.
- Scheduling.
- Controlling.
What are the phases of project management?
- Project Initiation.
- Project Planning.
- Project Execution.
- Project Monitoring and Controlling.
- Project Closing.
What is CPM and PERT techniques?
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 the PERT critical path?
It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is
determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish
.
What is a PERT diagram?
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. A PERT chart allows managers to evaluate the time and resources necessary to manage a project.
Which is are features of PERT CPM?
7. A PERT network is
activity-oriented
while a CPM network is event-oriented. Explanation: A CPM network is activity-oriented while a PERT network is event-oriented. Event is the completion of an activity or the commencement of an activity.
What does CPM stand for?
CPM stands for
cost per thousand impressions
and is typically used in measuring how many thousands of people your advertising or marketing piece has (hopefully!) left an impression on. CPM is typically used in campaigns that are designed to be seen by thousands of thousands of people.
What are the advantages of PERT?
- Planning For Large Projects in PERT – The scheduling of project activities is done easily with the help of the PERT system by the project manager. …
- Visibility of Critical Path in PERT – The PERT method will show the critical path in a well-defined manner.
