Zones can also be useful for grouping computers that form a natural administrative set or that should be managed by different administrative teams. For example, you may want to group computers that are managed by a local support organization in one zone and computers that are managed by a corporate IT group in another zone.
Using zones, you can then control what different groups of users can do within the zones they have permission to access. For example, you can set up regional zones to provide a separation of duties, authorizing users in San Francisco to manage computers and user profiles in their local office while a team in Barcelona has authority to join computers and manage group profiles for offices located in Spain.
Zones provide a convenient way for you to assign individual administrative responsibilities to specific users or groups based on a set criteria, such as department, geographic location, or functional role.
