Within each box, there are seven sections, each referring to a different piece of information about the task, such as its duration, its slack, and how early or late the task can start or finish. A project’s PERT chart contains a number of boxes, which each represent a project activity or task. The program evaluation and review technique (PERT) involves using a visual mapping tool known as a PERT chart to plan the overall project schedule. There can be other tasks involved in a project too, but if they are not on the critical path, they’re known as float tasks.
The critical path is the group of tasks essential to the project’s success, put in sequential order. Two other popular project management scheduling techniques include the critical path method (CPM) and the program evaluation and review technique (PERT).Ĭritical path method is an approach commonly used in construction project management that bases the project schedule on the project’s critical path, i.e., the number of tasks involved in the project and the order in which those tasks must be completed. Apart from using a Gantt chart, there are a number of other project management scheduling techniques that your team can choose from, depending on your project needs.
