Lead and lag

Gantt Suite supports dependencies with lag and lead.

Dependencies can be modified by leads, and lags. Both leads and lags can be applied to all 4 types of dependencies.

PMBOK defines lag as "the amount of time whereby a successor activity will be delayed with respect to a predecessor activity".

In accordance to PMBOK a lead is "the amount of time whereby a successor activity can be advanced with respect to a predecessor activity.


It is possible to set a delay (gap) between tasks by either moving the successor task after the predecessor using drag & drop or by manually editing the task's start date. However, auto-scheduling may eventually adjust the schedule, placing the successor task immediately after the predecessor.

There are a few ways to set lead or lag for a dependency once you hover over it:

  • Double-click the link.

  • Right-click the link and select Edit from the context menu.

  • Right-click the task and select Dependencies from the context menu.
