PERT: Meaning and Steps

pert and cpm techniques in project management

An effective project management is necessary to finish the projects without delay and with the available qualifications identified beforehand. A project is defined as a planned undertaking of related activities to reach an objective that has a beginning and an end. Activities with no slack time are said to lie along the critical path—the path that must stay on time for the project to remain on schedule. When things go wrong, however, the very thing that encouraged efficiency might suddenly cause confusion. For the project example used here, you will end up with the same task list as explained in the article on Gantt Charts we will use the same example as with Gantt Charts to compare the two techniques. The variance in the project completion time can be calculated by summing the variances in the completion times of the activities in the critical path.

If tasks are sequential, show which stages they depend on. WorkLenz is a software application that serves as a virtual project manager with intelligent agent features. In the diagram above, activities are 1 week long, 2 weeks long, and 1 day long. The earliest start and finish times of each activity are determined by working forward through the network and determining the earliest time at which an activity can start and finish considering its predecessor activities. There are three networking techniques commonly used as project management aids in planning and scheduling. After that, the dependency between the activities is determined. The understanding of your customer's organization will foster a stronger relationship between the two of you.

Week 5 1 week Parallel E L. There are many assumptions involved in each estimate, and these assumptions are illustrated in the three-time estimate he would prefer to give to each activity. It is a very important technique in the field of project Management. At Event 3, we have to evaluate two predecessor activities — Activity 1-3 and Activity 2-3, both of which are predecessor activities. Weeks are a commonly used unit of time for activity completion, but any consistent unit of time can be used.

This can help dispersed employees to operate efficiently by having a common understanding of the expected work flow. Thanks and All the best. The activities are represented by arrowed lines and events by circles. The aim was to finish the project two years in advance. The world we live in today is experiencing tremendous growth and rapid development; organizations are experiencing more competition now more than an ever and a project manager who wants to stand out would have to utilize all resources at his disposal to deliver quality results at a faster rate.

In this video we have done one illustration problem on which how to i construct the Project network ii Find the expected duration and variance of each activity iii Find the critical path and expected project completion time iv what is the probability of completing the project on or before some weeks. It is not necessary to go into the theory behind the formula. The project workbook is the primary source of information for producing all project reports. Fortunately, there are many tools available to assist with accomplishing the tasks and executing the responsibilities. It is important for project management software vendors to keep things simple and easy to use. There are some basic differences which, while they can be overcome or blurred in manual use of the technique, strongly influence the computer programs and techniques based on each technique.

Come on over and check it out! It is important to identify and distinguish the various activities required for the completion of the project and list them separately. In this method, first of all, a list is prepared consisting of all the activities needed to complete a project, followed by the computation of time required to complete each activity. A method to control cost and time. It provides the management a tool for forecasting the impact of schedule changes and be prepared to correct such situations. The process of the network analysis requires that the project planning be conducted on considerable detail from the start to the finish. Similarly, at Event 4, we find we have to evaluate two predecessor activities — Activity 2-4 and Activity 3-4. The difference in the latest and earliest finish of each activity is that activity's slack.

Critical Path Analysis and PERT

Once we reduce the project to network of activities and events and we estimate activity durations, we are in a position to determine the minimum time required for completion of the whole project. It is commonly used in research and development projects. Focusing too much attention on the critical path can cause managers not to notice possible production improvements in other activities. The greater the amount of adjustments a parent organization must make to fulfill project objectives, the greater chance exists for project failure. This gives the management an opportunity to shift attention to any critical task so that the entire project is completed in time.

The budget should summarize the planned expenses and revenues related to the project. The critical path is determined by adding the times for the activities in each sequence and determining the longest path in the project. It is further assumed that t p and t o are about equally likely to occur whereas the probability of occurrence of t is 4 times that of t p or t o. The understanding of the content and complexity of the project. They are given by: This supports the above concept. These are some of the examples of the use of float to schedule an activity.

When an activity has zero Total float, Free float will also be zero. Because of the nature of net working and net work analysis, it needs a high degree of planning skill and greater amount of details which would increase the cost in time and manpower resources, 3. List All Activities in the Plan For each activity, show the earliest start date, estimated length of time it will take, and whether it is parallel or sequential.
