Question

List and expain the six steps of the PERT CPM process. (Quantitative Analysis)

Answer 1

Program evaluation and review technique and Critical path method both are useful for project management and scheduling the work. The major steps involved in PERT are as follows

• Define the project and prepare the Work breakdown structure:- In this phase properly define the objectives of project, important milestone and work division for fulfilment of each milestone activities
• Develop the realtionship:- This includes set of activities or series of activities involve in a project and the inter realtionship of it , interdependence of each activities over other .
• Draw the basic network which connects all the activities:- this helps in giving a visual representation of interconnected activities,nodal points etc. This gives a proper idea about the successor and predecessor of activities and how many parallel activities are there .
• Assigning time and cost estimations:- This provides the time require for each activity and the estimated cost for each. This helps in evaluating the high cost and high time consuming activities.
• Compute the longest path involves which is also called critical path. This gives the important path which take longer time and any delay in the critical path can delay the entire project deadlines too.
• Make use of network to plan, schedule , monitor and control. :- This is the final step of activities to properly plan , scheudule and oversee the project progress abd contorlling it by putting things on track by following the network diagrams.
