Your contributions enable me to keep focusing on making new tutorials that all engineering students around the word can benefit from. Same goes for activities D, E and H.Thank you to ALL of my Patreon supporters. Note that float for critical path activities will always be zero even if they are common with the next longest (or any other) path.ĭo refer to the video for step-by-step calculation of float in the example below,Īctivity B has a float of 3 which means even if it gets delayed by 3 days the project end date won’t be impacted. The result of this subtraction is the float value for all the activities on the aforementioned path. Calculationįloat is calculated by first finding out the critical path and then subtracting it with the next longest path. The only reason for that is the fact that Float and Slack are essentially the same! Treat them as synonyms as far as Project Management and PMP is concerned.

It is fair to ask that question given how these two terms typically appear together. Now that you have a fair idea about Float, the next question should be about Slack. How much delay can the project absorb, that value is precisely known as float.Īn instant corollary should be that float for activities on critical path should be zero as the critical path activities cannot be delayed at all. Quick Definitionįloat is the amount of time that an activity can be delayed without affecting the project end dateĭoes that ring a bell from our discussion on Critical Path? We talked about how activities not on critical path can be delayed for a while without affecting the project end date. Before moving further make sure you already know about Network Diagrams and Critical Path. We have already discussed some of the important topics that are the basis for this article on Float.
