Manage the individuals who can access your instance by defining them as users in the
system. Create user groups, and assign users to them. Use roles to specify what different users
and user groups can see and do.
A group is a set of users who share a common purpose. Members of groups perform tasks such as
approving change requests, resolving incidents, receiving email notifications, or performing
change request tasks. Assign every user to at least one group.
A good practice is to assign roles to groups rather than to users. Administrators can assign
roles quickly to multiple users by adding the users to the group. If a user moves to another
group, the role assigned to the new group is applied automatically.
