PROJECT MANAGEMENT
Project Scheduling - Time (CPM and PERT) (E)

 

Project Management

 

 

What is the project? How to select and justify the project? How to plan and execute the project?

 

Posted: Oct 2010


Two methods used for time scheduling of the project, Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT). The four steps to developing a project schedule are the following:

The critical path method (CPM) and program evaluation and review technique (PERT) are methods for estimating the duration of project tasks. The two methods can be used separately, but many projects are planned by both methods.

The purpose of CPM is to calculate the estimated completion time for the previous example. Using the tasks that take the longest, the critical path would look like this:

Task A, Task B, Task C, and Task E. Task D would not be part of the critical path since it can be done simultaneously with Task C and will take less time than Task C. The total estimated time to completion then is:

CPM

Task A (5) + Task B (10) + Task C (8) + Task E (2) = 25 time periods (minutes, hours, etc.)

Project Management is a management method that is used to plan, organize and control project activities. The project is initiated by executive committee that will initiate project work.The basic concept of Project Management is the delegation of general management authority to the Project Leader.



Another method for estimating the duration of activities is PERT. It is referred to as a probabilistic method because it uses a weighted average of three estimates of the duration of an activity. It is preferred when there is a high degree of uncertainty regarding the duration of a task.

Using PERT, the time estimate is determined with the following formula:

T = (O + 4M + P ) ÷6 
 
T –
expected time
O = most optimistic estimate of time
ML = most likely estimate of time
P = most pessimistic estimate of time
