Here, in the article, you will earn about critical path calculation. You can download free PDF for a full explanation of critical path calculation in project management.
Critical Path Definition
-It’s a sequence of activities where you figure out what the least amount of time is necessary to complete an activity with the least amount of float. So, the critical path is really the longest duration it will take to complete the project.
-The critical path is the longest distance between the start & the finish of your project, including all the activities, their duration, which gives you the actual picture of the project’s actual schedule.
Total Float Definition
Total Float is the amount of time which an activity can be delayed without delaying the project end date.
Total float calculated by subtracting the Early Start date of activity from its Late Start date
(Late Start date – Early Start date), or Early Finish date from its Late Finish date (Late Finish date – Early Finish date).
Free Float Definition
Free float is the amount of time which an activity can be delayed without delaying the early start date of the successor activity.
Free float calculated by subtracting the Early Finish date of the activity from the Early Start date of the next activity (ES of next Activity – EF of current Activity).
When you identify the critical path for the project, you can determine the float for each activity. The float is the amount of time an activity can delay before it causes your project to be delayed . A float is sometimes referred to as slack.
Figuring out the float using the Critical Path Method (CPM) is easy. You will start with the activities on the critical path. Each of those activities has zero float. If any of those activities delayed, the project will be delayed.
