# Establish task dependencies

We need to define dependencies in our project schedule to ensure that the tasks are completed in the appropriate sequence.  Specifically, when the predecessor task is completed, the successor task can be started. 

A well-designed dependency network defines all these relationships ensuring that all work is scheduled in the appropriate sequence to deliver the project as quickly as possible.  
 

To establish *dependencies:*

1.  Ensure you have the appropriate project open with the **Task** tab selected and the **Timeline view** active.  
     
2.  **Hover** your mouse over the end of the **Gantt bar for the successor**, and then click and drag to the **beginning** of the successor task.  
     
3.  Release the mouse to create the dependency.  
     
4.  Create additional dependencies in the same way.   
     
5.  **Gaps** and **Overlaps** can be created by dragging the **Blue Gantt bar.**  
     
6.  Dependencies can be **deleted** by **right mouse clicking** on the end of the dependency arrow and selecting **Delete Dependency** and selecting the appropriate one to delete.
