The easiest way to create a new resource is with the Assign Resources dialog. It contains not only the capability to assign resources, but also to delete assignments, replace resources on assignments, and to view work and availability graphs about resources.
The important thing to remember about this dialog is that it always contains assignment information about the currently selected task and you do not have to close it to select a new task. You can still change the selected task while this dialog is open . This makes it a convenient way to view and edit assignments on tasks .
