You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Float or slack is the amount of time that a task in a project network can be delayed without causing a delay to subsequent tasks ("free float") and project completion date ("total float"). Powerpoint Pro V2 Presentation Maker. B (one month longer) This task is on the critical path,This is the time by which an activity may be delayed or extended without affecting the preceding or succeeding activities in any way. It is thus equal to the head event slack. In general, float is the amount of time you can wait to start something and not make it 'late'. It is also equal to the head event slack of the activity Thus interfering float of an activity - TF - EF = (L-E) of the head event of the activity Subcritical Activity : Activity having next higher float than the critical activity is called the subcritical A.
