it supports the analysis of these actions and their sequential arrangement, along with determining the proposed duration required for completing each of these tasks with the help of drafting a critical path, is termed as pert analysis. when the organization undertakes a new project, it becomes difficult to determine the time within which the project has to be completed. therefore, to provide the deadline for every task involved in the project and guide them on the sequence of all the activities, pert analysis is considered to be the most suitable method. it also provides an idea of the series in which the various activities are to be carried out and the proposed time taken to complete each task.
pert seems to be a complicated method; however, it is not so if we have a basic understanding of the formulae used in this technique. it is calculated through the following formula: the level of volatility of the time required to carry an activity from the average time is termed as variance in pert analysis. the esj and lci for all the ten events are as follows: as we know that the critical path is the longest path of the pert chart connecting the nodes which fulfil all the four conditions mentioned above. the following table will provide the required data: some may find pert analysis to be a complicated method; however, it is an entirely practical approach in business project planning, which involves huge finance.
it analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project. it estimates the shortest possible time each activity will take, the most likely length of time, and the longest time that might be taken if the activity takes longer than expected. pert analysis informs program managers and project personnel on the project’s tasks and the estimated amount of time required to complete each task. to conduct pert analysis, three-time estimates are obtained (optimistic, pessimistic, and most likely) for every activity along the critical path. after completing step 1, use the (optimistic, pessimistic, and most likely) estimates in the formula below to calculate the pert estimate for the project. although critical path method (cpm) and pert are conceptually similar, some significant differences exist mostly due to the type of projects best suited for each technique.
pert handles uncertainty of the time required to complete an activity by developing three estimates and then computing an expected time using the beta distribution. the percentage of completion of the activity than can be determined.  in 1958, the u.s. navy introduced network scheduling techniques by developing pert as a management control system for the development of the polaris missile program.  pert was introduced as an event-oriented, probabilistic technique to increase the program manager’s control in projects where time was the critical factor and time estimates were difficult to make with confidence. the events used in this technique represent the start and finish of the activities. an expected time is calculated based on a beta probability distribution for each activity from these estimates.
