Groups and roles may seem to be similar concepts, but they have different purposes. Roles are used to grant apps to users, groups are used to delegate administration of users. In a large organization it does not if one person has to manage all users in the organization and groups can help by delegating administration of a collection of users to one individual.
You can create and manage groups under People -> Groups. A group consists of a name and the user who is responsible for managing the group. For example, someone in the Engineering department may be response for all uses in Engineering.
