PERT & CPM Chart

In this section, we will learn about the PERT & CPM Chart. Therefore, let’s begin.

CPM Chart –

• Firstly, a Critical Path Method (CPM) is a tool to analyze the project and determine the duration. Moreover, it is based on the identification of “critical path” through an activity network. Also, CPM permits project managers to change duration.
• Secondly, CPM is like a network diagram. In other words, all the steps in the project are connected. Further, you can go through these steps to determine which path dictates the longest amount of time to get through the entire end-to-end process.
• Thirdly, it lays out the longest path of planned activities to the end of the project as well as the earliest and latest that each activity can start and finish without delaying other steps in the project.

PERT Chart –

• A Program Evaluation Review Technique (PERT) refers to a form of diagram for CPM that shows activity in an arrow diagram. However, PERT charts are simpler as they simply show the timing of each step of the project and the sequence of the activities.
• After that, PERT chart is a graphical representation of a project’s schedule which shows the sequence of tasks, which tasks can be performed simultaneously, and the critical path of tasks that must be completed on time in order for the project to meet its completion deadline.
• Lastly, it can record an entire project or a key phase of a project. The PERT Chart permits a team to refrain from unrealistic timetables and schedule expectations, to help identify and shorten tasks to focus attention on most critical tasks.
