Introduction :

Project management involves a series of complex activities, which need to be planned, organized, and executed efficiently to achieve the project goals. One of the essential aspects of project management is determining the critical path. The critical path is the longest sequence of dependent activities that must be completed on time for the project to be finished within the scheduled timeline. In this task, we are given a table of activities with their duration, and we need to determine the critical path by creating a PERT chart and calculating the earliest start time, earliest finish time, latest start time, and latest finish time for each task.

PERT Chart :

Program Evaluation and Review Technique (PERT) chart is a graphical representation of a project's tasks, their dependencies, and the expected time required to complete each task. A PERT chart helps to visualize and organize a project's timeline, allowing project managers to identify the critical path and optimize resources to complete the project on time.

How to Determine :

To determine the critical path using a PERT chart, we calculate the earliest start time (EST), earliest finish time (EFT), latest start time (LST), and latest finish time (LFT) for each task. The critical path is the sequence of tasks that must be completed on time to ensure that the entire project is completed on schedule. The critical path is determined by identifying the tasks that have no slack or float, which means that any delay in completing these tasks will result in a delay in the entire project. The critical path is the longest sequence of tasks from the first task to the last task that has no slack or float.
