Slack time is the amount of time that an activity can be delayed without delaying the project’s finish date. It is calculated as the difference between the activity’s latest start time and its earliest start time.
An activity is a task that must be completed in order to finish the project. An event is a point in time at which something happens, such as the start or finish of an activity.
