With the PERT Analysis, the expected entire project duration and the probability with which the specific deadline can be reached is calculated. This method ensures that the probability of the time duration of each task taking more time than estimated has been minimized. The weighted average is used to calculate the time estimate for each task. The duration estimates range from the best case to the worst case and assume that these estimates are accurate. The time for each task is calculated by estimating three durations: Optimistic, Realistic and Pessimistic. The PERT Technique starts by understanding all the tasks required for the project to complete and how much time it would take each activity to complete. PERT is often mentioned in conjunction with the Critical Path Method (CPM), a similar statistical method for forecasting progress which was developed by project management personnel in the private sector around the same time as PERT.Īlthough there are strong similarities between both techniques, they are complementary tools and are often referred jointly as the PERT/CPM technique. PERT was used from 1965 till the opening of the 1968 Games. The 1968 Winter Olympics in Grenoble is an early example of the usage of the PERT technique. Thus, the technique is most suitable for large-scale, one-time, complex, non-routine infrastructure and Research and Development projects. Navy’s Special Projects Office in cooperation with the management consulting firm of Booz, Allen, and Hamilton when developing the Polaris submarine missile program in 1957. This methodology is favorable for projects where time is a bigger concern than cost, thus this methodology is a popular event-oriented technique. PERT Methodology allows the project manager to devise a budget depending upon the duration of the project without knowing all the details and durations of the tasks and to closely monitor the progress of the project. The PERT chart is a crucial part of PERT methodology as it shows how to schedule, organize and coordinate tasks during a project. PERT or Project Evaluation and Review Technique is a statistical tool that is used in project management to estimating the minimum time required for a project to complete by analyzing all the tasks required and by calculating the minimum time it would take to complete each task in the project. In addition, there are some do’s and don’ts of PERT methodologies that we deem essential to project management for all sorts of managers. If you are a project manager who is just about getting started in the industry, our PERT guide will help you to avoid the pitfalls, which usually the new ones fall in. The following write-up is not a detailed analysis, but it is more than enough to give you a gist of what PERT is. However, we decided to dedicate this weak to the Project Evaluation and Review Technique. The weird thing is that this phenomenon is common all over at different productivity blogs. Since we preach so much about project management and productivity, there aren’t a lot of case studies going on.
