Abstract
Program Evaluation and Review Technique, known as PERT, is a powerful tool used by project managers to plan and execute complex projects. PERT breaks down complicated projects into smaller and more tangible tasks and develops a network diagram with the tasks. The network diagram describes the relation and dependencies between each task and durations for each individual task is estimated. The time estimate of tasks can be calculated through a simple formula taking both a pessimistic, most-likely and optimistic estimations into account, providing an improved projection of the project timeline and deliverables. [1]
A critical path is identified and determined within the network diagram, which is the path of tasks the project must complete on time for the entirety of the project to finish on time. [2] Thus, the critical path determines the time duration of the entire complex project. If tasks on the critical path is delayed, the entirety of the project will be behind schedule. The critical path highlights the tasks that focus for the project to become a succus. Mangers using PERT can include a risk management of the individual tasks to identify problem areas and create a plan to deal with the potential of these problems.
PERT visualizes the tasks needed to complete to finish the project. [3] This can greatly help managers to improve communication, planning and scheduling, identify project stakeholders and improve the execution of the project. PERT is an extremely flexible tools which can be tailored to help the project managers with their specific need, for them to best deliver on their goal or project. This article will provide a guide for project managers to implement PERT when tackling complex projects and a thought example of a project where PERT and CPM is applied to estimate the duration.
