The Gantt view displays a timeline for a schedule or template that graphically represents the duration of tasks and the dependencies between them. Bars represent duration, and arrows represent dependencies. You can view the predecessor relationships between tasks, for example, Task A must complete before Task B, and view the status of predecessor tasks. You can also see the parent-child task relationships (aggregations), in the hierarchy, for example, Task A is comprised of two subtasks, Task B and Task C.
You might choose to use the Gantt view when you create a template to see the predecessor relationships between the tasks, or to verify the precedence order after adding tasks to a schedule. You can use the Gantt view to see the status of predecessor tasks to other tasks, and see the status of tasks that are predecessors to other group member tasks.
Within the Gantt Chart and Calendar views, viewing a schedule or template with a very large number of tasks may cause the view to cycle a very long time. It is recommended to filter the view down to a smaller number of tasks when reviewing the schedule or template in these views.
You can drag new tasks into the Gantt view and update a task using a double-click or menu option. You can drag a task to a new start date and stretch the task duration. You can filter to flatten the task hierarchy and sort by task status. Tasks that have child tasks are indicated by an arrow, which you can click to expand or collapse the task hierarchies.
