Roles ease the management of permissions for a large number of users. The permissions for a group of users who are assigned to the same role can be updated by changing the role. This saves having to update each user’s permissions individually.
For example, if 40 operators need access to a new component in the station, you may need to update only their shared operator role, and then only if a category has been added or permissions need to be changed. The initial configuration of a station’s security, which involves object permission levels, object categories, roles (permissions) and users may take time to design and set up in some configurations, but the trade off is worth the future time saved when updating the permissions of more than one user at a time.
