Abstract
The focal point of this article will be the Program Evaluation and Review Technique (PERT), which is a project management tool used for the scheduling, coordination and control of complex projects. The U.S. Navy originated PERT in 1958 as a tool for scheduling the development of a complete weapons system [1]. It is a network-based technique that uses a flow diagram to represent the interdependencies of tasks in a project.
After the tool's description, this article's outline will follow with the purpose and advantages of this method. The goal of PERT is to provide project managers with a visual representation of the project timeline and to help identify the critical path and critical tasks, which must be completed on time for the entire project to be on schedule and meet the assigned deadline. In addition, PERT provides project managers with a way to estimate project finalisation time and identify potential bottlenecks and risks in the project itinerary.
Subsequently, this article will thoroughly explain how to use the PERT and when its application will be accurate within the estimation of a project. To build a PERT diagram, specific steps must be followed to allocate resources and ensure that the project stays on track.
On the other hand, PERT also has several limitations that will be covered in this composition. For instance, this method has dependency limitations, meaning that activity durations are assumed to be independent [2]. Despite these disadvantages, which will be addressed below, PERT remains a valuable tool for project management and can be used effectively when its limitations are considered.
Finally, this article will propose new approaches and tools for project estimation that will help overcome the PERT limitations.
Keywords: PERT, project management, tool, tasks, duration, estimation, resources and cost.
Introduction
Project Management
- What is a project?
In order to better understand what project management entails, the concept of a project should be explained in advance. Therefore, projects can be defined as temporary efforts to create value through unique products, services, and processes (Project Management Institute, 2023) Cite error: Closing </ref> missing for <ref> tag [2] [3] </references>
