A Difference Between the Program Evaluation and Review Technique and Critical Path Method Is That

PERT and CPM are the tools that are used to manage and schedule the events and activities of the project. Both of these tools are used to manage or control time. These tools also maintain the resources and many other aspects of the project. To achieve the project goals these tools are very helpful. Both the tools are network-based which shows the catamenia sequence of the events and the activities. In this article, we will talk over in detail the difference between PERT and CPM. The plan evaluation and review Technique (PERT) is suitable for the projects where completion time of projects is unknown. And (CPM) Critical path method is adopted where the completion time of the project is stock-still.

CPM is used in the construction industry. In the structure industry, in that location are many types of major projects. Mostly these projects have to be completed in a certain fourth dimension period or every bit fast equally can. There are many big projects in civil construction like road projects, Hydroelectric projects, and many other large constructions of conventional sources of energy. These methods have a common arroyo to designing the network to find its critical path. There are used for the successful completion of the projection so, they connect with each other. But at that place are many differences betwixt Pert and CPM which nosotros will discuss in this article.

PERT vs CPM

Parameters	PERT	CPM
Meanings	It is a direction technique that is used to manage uncertain activities and events of a projection.	CPM is a direction Method used to manage defined activities of a particular projection.
What is it	A planning technique is used to command the project'southward completion fourth dimension.	CPM is a method that is used to control the cost and time of the project.
Preference	PERT gives preference to events of the project.	It gives preference to the activities of the projection.
Evolutions	It is evolved every bit a enquiry and development projection.	CPM is evolved as a construction projection.
Model	Probabilistic.	Deterministic.
Main focus	Time	Trade-off and Time price.
Estimates	Three times	Single time.
Fits for	Time estimates with high precision.	Reasonable time approximate.
Nature	Non-repetitive.	Repetitive.
Used for	Uncertain and unpredictable activities.	Fixed or predictable activities.
Crashing	The crashing concept is Non applicable	Crashing concepts is applicative.
Suitable for	Evolution and research projects.	Civil construction and other not-inquiry projects.

What is PERT

PERT stands for Program Evaluation and Review Technique. This technique is used to programme and identify the fourth dimension taken for the completion of particular activeness and outcome of the project. In this planning technique organizing, coordinating, scheduling, and controlling uncertain activities takes place.  Charts are created in PERT which shows the graphical representation of the events and the activities. This technique studies and shows the least time is taken to consummate the activity and minimum time for the completion of the projects.

This technique uses fourth dimension as a variable. The part first role is to break the project into the events and the activities. Later the breaking of the project next pace is to make proper sequence is managed. And then time is considered for each event and the activity and then notice a critical path.

History of PERT

United states Navy special projects office Missile system partitioning developed pert dorsum in 1957. Pert is adult during the product of the UGM-27 missile. And and then it is implemented in the winter Olympics from 1965 to 1968. The primary aim of this technique is to reduce the cost and time of the project.

Advantages of PERT

• In PERT after the analysis of the critical path, the dissimilar types of uncertainties tin be identified.
• Pert promotes the coordination between other departments of the projects which is very helpful in the decision making.
• Its nautical chart networks prove all the activities past which it is easy to notice that project will complete within the desired budget.
• Pert is time-focused.

What is CPM

CPM stands for Critical Path Method. It is a modeling technique of the projection in which scheduling of projection activities is done in an effective way. This model finds the maximum time taken for an activeness. In CPM information technology Is predicted that the earliest and latest start fourth dimension is possible for every action. As the name indicates the critical path is identified considering if an activity delays all activities have to exist suffered.

In CPM all the activities are listed which accept to perform or complete for the projection completion. After that, the sequence is maintained because many activities are dependent on previous activities. Just means some actives are on starts after the completion of the previous activity. And so estimates the time required for the completion of each activity. subsequently that a disquisitional path is selected. The disquisitional path is the longest sequence of the activities that have to complete on time.

Advantages of CPM

• It identifies the dependency of the activeness very effectively
• CPM identifies critical activities that are very important.
• It also accounts for the sources to be needed for the project.
• It is very helpful to make up one's mind the cost and time for the completion of the project.

Difference Between PERT and CPM

PERT	CPM
Information technology is a project management technique in which planning, scheduling analogous, and controlling of uncertain activities are performed.	CPM is a statical tool or method in which scheduling, planning, organizing, and controlling of divers activities are performed.
Pert manages panning and control on fourth dimension management of the project.	It controls the time and cost of the projection.
It is evolved as a enquiry and development project.	CPM evolved as a construction projection.
PERT is aligned as events.	It is aligned as Activities.
Information technology uses a probabilistic model.	CPM uses a deterministic model.
3 times estimates used in PERT.	A unmarried fourth dimension judge is used.
PERT is best for high precision time estimates.	It is best for reasonable time estimates.
Information technology deals with unpredictable activities.	CPM deals with anticipated activities.
The crashing concept is Non applicable	Crashing concepts is applicative.
Main focus on fourth dimension	Focus on cost and time.
Pert is best suitable for research and development projects.	CPM is all-time suitable for construction projects.

Conclusion

Both of these techniques are very important for project management. PERT and CPM both are time direction techniques. In this current time is very valuable. All of us know that time is money. With the assist of these techniques, we can hands await at the progress of the projection with respect to time and cost. CPM is very helpful to minimize the cost of the project in an constructive mode.

This is all about the divergence betwixt PERT and CPM. Nosotros hope you empathise the concept. If y'all have whatever suggestions please comment on united states of america. For more difference delight go through our website.

What is PERT

PERT stands for Program Evaluation and Review Technique. This technique is used to plan and place the fourth dimension taken for the completion of particular activity and event of the project.
