Slack time
- It is the amount of time a task can be delayed before the project finish date is delayed. Thus, the slack is the difference between event times denoting the range within which an event time can vary.
- The Earliest Expected Time (TE) is the time when an event can be expected to occur earlier.
- The Latest allowable occurrence time (TE)is the latest time by which an event must occur to keep the project on schedule (without delaying the project).
- Event slack is defined as the difference between the latest event and the earliest event times. i.e. Slack = TL - TE
If TL is the largest allowable event occurrence time, total activity slack (s) is equal to
Latest start time - earliest start time
Latest finish time -earliest finish time (EFT)
Latest allowable event occurrence time - Early finish time
