Lag and Negative Lag in Dependency Relationships

You can define the lag between tasks as positive or negative. Lag is the predetermined amount of time between the start and/or finish time of two tasks in a project plan. Negative Lag is the amount of time or percentage of task duration in which two tasks can be simultaneously in process in a project plan. You define lag or negative lag on the Dependencies tab of the Task Properties dialog.

Example - Positive Lag

You have two tasks in your project, Task A and Task B, and you want Task B to start three days after Task A finishes. Define the dependency type as Finish-Start type and enter 3.00 as the lag.

Example - Negative Lag

You have two tasks in your project, Task A and Task B, and you want Task A to start two days before Task B ends. Define the dependency type as Finish-Start and enter -2.00 as the lag.
