What is the difference between leads and lags?

Lead and lag are both used in the development of the project schedule. Lead is an acceleration of the successor activity and can be used only on finish-to-start activity relationships. Lag is a delay in the successor activity and can be found on all activity relationship types.

What is lag and lead time?

When you add lead time to a task, work on that task overlaps work on its predecessor. When you add lag time, you delay the start time of the successor task. Before you can start adding lead or lag time, you need to create a dependency between the two tasks.
