On the Job Gantt view, you can create dependencies if tasks are required to be done in a certain order.
When tasks are set up with dependencies, Any changes to the required task will push out the dependent task along with any scheduled time.
Please be careful when reviewing these changes as the shift in the dependent tasks start date may have caused scheduled time to fall into a weekend or possibly clash with scheduled time for other tasks.
To create a dependency, simply hover over the required task on the Gantt. Whilst hovering you will see a dot appear just after the tasks due date. As you click and drag away from the dot, a dashed line will follow your cursor, continue dragging until you reach the start date of the dependent task.
To delete a dependency, simply double click on the dependency line connecting both tasks.
