The Programme Evaluation Review Technique (PERT) and the Critical Path Method
Critical path method
The critical path method (CPM) is an algorithm for scheduling a set of project activities. The critical path method (CPM) is a project modeling technique developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley, Jr. of Remington Rand. Kelley and Walker related their …
What is the difference between CPM and Pert?
Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT) are popular time management tools used by managers to coordinate the projects. Both are used for designing the project network and show a logical sequence of activities incomplete or in progress.
What is Pert in project management?
In project management, the 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.
What is critical path in PERT CPM?
The Critical Path in PERT CPM The critical path is the sequence of project network activities in CPM and PERT. It determines the duration of the tasks and hence, of the entire project. Delay in its task delays the project.
Why do we use Pert instead of time?
Working Apart. Because PERT assumes that the duration between tasks is probable instead of absolute, it does a better job of capturing the risks for projects such as research and development, in which the time taken to complete each task is more uncertain.
What is the importance of PERT and CPM in strategic management?
The techniques of PERT and CPM help greatly in completing the various jobs on schedule. They minimise production delays, interruptions and conflicts. These techniques are very helpful in coordinating various jobs of the total project and thereby expedite and achieve completion of project on time.
What is the purpose of PERT CPM how is it used in the industry?
PERT and CPM assist management in identifying the longest time-consuming, or consuming path through a network of tasks or activities as a basis for planning, executing, and controlling a project. The techniques help managers to optimize the longest time duration in order to minimize the total project cost and time.
How would PERT and CPM techniques be used in decision making?
1. 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.
Where is PERT and CPM used?
PERT (Program Evaluation and Review Technique) was first used in the development of submarines capable of firing Polaris missiles. CPM (the Critical Path Method) was used to manage the annual maintenance work in an oil and chemical refinery.
What is PERT and CPM explain with examples?
PERT – PERT is a popular project management technique that is applicable when the time required to finish a project is not certain. CPM – CPM is a statistical algorithm which has a certain start and end time for a project. Model Type. PERT – PERT is a probabilistic model. CPM – CPM is a deterministic model.
What is PERT business management?
Program Evaluation Review Technique (PERT) is a project management planning tool used to calculate the amount of time it will take to realistically finish a project. PERT charts are used to plan tasks within a project — making it easier to schedule and coordinate team members.
Which of the following is an advantage of PERT & CPM?
Both PERT and CPM are essential project management tools that divide the activities as per function and responsibility that helps in proper coordination of work with the different teams involved in the project. It allows the managers to take timely decisions that reduces delays in the completion of projects.
When the PERT CPM was first used?
First developed by the United States Navy in 1958, it is commonly used in conjunction with the critical path method (CPM) that was introduced in 1957.

What are the uses of PERT?
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 CPM and where it is used?
The critical path method (CPM) is a technique where you identify tasks that are necessary for project completion and determine scheduling flexibilities. A critical path in project management is the longest sequence of activities that must be finished on time in order for the entire project to be complete.

What is the difference between CPM and PERT?
PERT and CPM are techniques of project management useful in the basic managerial functions of planning, scheduling and control. PERT stands for “ Programme Evaluation & Review Technique” and C PM are the abbreviation for “Critical Path Method”. These days the projects undertaken by business houses are very large and take a number of years before commercial production can start.
What is the very careful technique of CPM and PERT?
What we have basically described above is the very careful technique of CPM and PERT which consists of decomposing project into activities and then ordering activities according to their relationships to find out the shortest time required to carry on an activity.

What would a budget officer do with the total value of sales schedules?
He would also estimate market prices of the sales and give the total value of sales schedules of the units to be produced and assign machines for their manufacture. He would also plan the requirements of labour and other inputs and give all these schedules together with the number of units to be produced to the accounts manager who would provide cost of production data to the budget officer.
What is the longest path in a network?
To do so, we must find the longest path or sequence connecting the activities through the network. This is called the ‘critical path’ of the project. The longest path is the critical path. In our example, there are two paths. One is connecting circle numbers 1, 2, 4 and 5. This path will take 14+10 + 10 = 34 days.

But use of these tools does not guaranty the desired outcome due to bad management problems, natural calamities, strikes by labors etc.
What is the difference between CPM and PERT?
The difference between the CPM and PERT is that the PERT is mainly used where the time required for completion of each of the activities involved cannot be accurately defined nor are the resources to be used for the activity readily available. The events could however be readily definable.
When to use CPM?
CPM is used where activities are definable and measurable and minimum overall cost is of the utmost importance. Most large projects can be portrayed by a graph or network of jobs. Characteristics of construction projects to make it amenable for analysis by PERT or CPM are:
