Create Task Dependencies

Create task dependencies in the same project from the Gantt view. When you link two tasks in the WBS, a finish-start dependency is created by default. The topmost task in the hierarchy sequence becomes the predecessor and the bottommost task the successor.

Drag-and-drop the Gantt bars to create any type of task dependency. Once created, you cannot change the dependencies using drag-and-drop, but can move tasks without affecting the dependency. To edit the task dependencies, use the task properties page.

You cannot create dependencies to and from summary tasks.

In the WBS, expand a collapsed summary task to view the dependency lines between its detail tasks and other tasks.

Follow these steps:

1. Open the project.
2. Open the Tasks menu and click Gantt.

   The Gantt view appears.

3. Do one of the following:
   • In the WBS, select the check box next to the two tasks to create a dependency between them, and click the Link icon.
   • In the Gantt chart, grab the source taskbar and drag-and-drop it on the destination taskbar. Use the following guidelines:
     • Drag the right edge of the source taskbar and drop it on the left edge of the target taskbar. Creates a finish-start dependency.
     • Drag the left edge of the source taskbar and drop it on the right edge of the target taskbar. Creates a start-finish dependency.
     • Drag the left edge of the source taskbar and drop it on the left edge of the target taskbar. Creates a start-start dependency.
     • Drag the right edge of the source taskbar and drop it on the right edge of the target taskbar. Creates a finish-finish dependency.
