Groups, roles, and policies are ways to control who can access the Vocera system and the actions they can perform.
System administrators can establish groups, roles, and policies to manage the system efficiently.
Group is a collection of users with a given set of voice permissions assigned to them. A role is a collection of policies, and a user effectively inherits the policies when assigned a role. The individual policies that we assign to a role are called policy items, and a set of policy items are defined in a policy. Policies are established to govern and manage the system.
The following figure shows the association between user, group, role, policies.
