Slack Time
The amount of time a task can slip before it affects another taskÍs dates or the project finish date. [D01857]

The amount of time a task has been delayed from its original baseline plan. The slippage is the difference between the scheduled start or finish date for a task and the baseline start or finish date. Slippage can occur when a baseline plan is set and the actual dates subsequently entered for tasks are later than the baseline dates or the actual durations are longer than the baseline plan durations. [D01858]

The amount of slack or float time used up by the current activity due to a delayed start. If an activity without float is delayed, the entire project will slip. [D01859]

Differences between two groups are played down and the strong points of agreement are given the most attention. [D01860]

In resource-scheduling, this refers to an option that modifies the way time-limited scheduling (and resource-limited with thresholds) works. The objective of time-limited scheduling is to minimize the maximum extent that each resource availability needs to be exceeded, and the standard algorithm gives itself the maximum flexibility to achieve this by making use of any excess already incurred. The smoothing option modifies this so that it will not use the excess for a particular activity unless necessary in order to schedule that activity within its total float. [D01861]
