A PERT diagram not only shows the relationship among various steps in a project, it also serves as an easy way to calculate the critical path.
Correct Answer: A
A PERT (Program Evaluation Review Technique) diagram is indeed used to show the relationships among various steps in a project. It is a project management tool that lays out the tasks necessary to complete a project and the time associated with each task. By calculating the earliest start and finish times for each task, it is possible to identify the critical path, which is the sequence of tasks that determines the shortest time possible to complete the project. Any delay in the critical path will delay the entire project. Therefore, a PERT diagram serves as an easy way to calculate the critical path, making the statement true.
