CNST 361 2-21-08 Shared float identifies the fact that the number associated with total float is available (as a total) for all the activities within a path. For example; a path in the schedule made-up of 5 activities has a total float of 7. There are not 7 days of ‘play’ associated with each activity (total of 35 days). If any combination of activities in this path uses the 7 days the total float would drop to 0 and this path would also become critical Shared float is also referred to as Path Float, String float, and Interface Float. Free Float is often referred to as the float associated with a single activity. If there is an opportunity to delay the start or finish of an activity without delay in the earliest start of that activity’s successor; then we are using-up free float. Free float does not reference the predecessors to an activity in order to make a calculation. Independent Float also refers to the float of a single activity:

Unformatted text preview: The difference is that the value of independent float has no effect on either the start or finish of activities directly typing into it. The value associated with independent float will be equal to, or less than Negative Float is a total float value that results when a project is behind schedule. The value becomes negative because the calculations for the early finish of the last activity is past the project agreed-upon end date. When the late dates are calculated; the agee-upon end date is used as the late finish. For example; the agreed-upon end-date is day 20. The early finish of the last activity is day 25. The late finish on the last activity (for the start of the late date calculations) is day 20. Total float = LF-EF = 20-25 = -5 Chapter concludes with discussion on ownership of ‘float’. What options exist with ownership of float....
