Can you explain Float and Slack?

 Posted by ArticlesMaint on 9/30/2009 | Category: Project Management Interview questions | Views: 9323

Float (also known as slack, total float and path float) is computed for each task by subtracting the EFT from the LFT (or the early start from the late start). Float is the amount of time the task can slip without delaying the project finish date. Free float is the amount of time a task can slip without delaying the early start of any task that immediately follows it. In the previous question figure ‘EST, EFT, LST and LFT’ we have computed the float for every activity. For instance ‘Get Faculties’ has a slack of 10, ‘Advertisement’ task has a slack of 20 days and so on.
