2022 PMP Critical Path Method: How to Calculate Critical Path

The PMP Critical Path Method (abbreviated as CPM) is one of the most widely used schedule network analysis techniques, as described in the online PMP courses. The PMP Critical Path Method is based on determining the longest path through the network diagram.

Once the schedule network has been created during Project Schedule Management’s develop schedule process, you will be able to determine the start and end dates for each activity. This information will be available from the beginning of your project until the end. The order in which activities are completed will depend on their relationship. The PMP critical path method is used to determine the longest possible path between the start and the end of an activity. This will give us the duration of the project. We will be discussing how the PMP critical pathway is calculated and the key points regarding the PMP critical route method. This method is very important, so make sure to include it in your PMP study plan. You can also use the online PMP exam simulator to test your knowledge.
What is the definition of PMP Critical Path and Near Critical Paths?

The PMP Critical Path definition PMBOK pdf explains that it is the “longest duration path through a network diagram” and determines the fastest time to complete a project. The project duration will be determined once the PMP critical path has been established.
The PMP Critical Path is determined when all activities are identified from the beginning to the end of the network diagram. After identifying all possible paths of activities, the longest path from the beginning to the end will be the PMP critical path.
Near critical path is the closest path to the critical path in terms time. Let’s assume that your critical path for your project is 18 months. If 17 months is the closest path to 18 months as shown in the network diagram, then this will be the near-critical path.
What is Float?
It is better to describe Float in this context. Slack is also known as Float. It refers to the time that an activity can be delayed, without causing project delays. There are three types of float. Let’s take a look at each one.

Total Float: Total float is the amount time an activity can be delayed, without delaying the project’s end date or any intermediary milestone. Let’s say that a project activity does not meet the PMP critical path. This activity is not on the PMP Critical Path so any delay can be compensated. There is a limit to this. You can’t delay it too long and you risk exceeding the PMP critical path duration, which will lead to project delays. This tool allows you to determine how long you can delay an action without affecting the duration of your project.
Free float: This refers to the time that an activity can be delayed but not delaying its early start date. The activity’s early start date shows when the activity can be started. An activity’s success will depend on the availability of other activities and constraints. It will therefore have an early start time. Free float is the time that an activity can be postponed without affecting its early start date.
Project Float is the amount of time that an activity can be delayed, without delaying an externally imposed project completion.
PMP critical path activities must have zero floating points. This is because PMP critical path activities have the longest project completion path, so any activity on the critical path should have zero floats. Project delays will be caused by any delay in a PMP-critical path activity.
How is the Float of an Activity Calculated?
Two ways to calculate the float of an activity are possible. Either the early start is subtracted from late finish, or the early finish is subtracted form late finish. Ho
