A business role is defined as a named specific behaviour of a business actor participating in a given context. The actor performs the behaviour of the role.

A business role can be fulfilled by more than one business actor. Conversely, a business actor may fulfil more than one business role. For example, given a named teacher, their roles may include those in the domains.

A business role will usually exist in an organisation whether or not a given actor fulfils it or not.

A business role may be assigned to one or more business processes or business functions. A business interface or an application interface may be used by a business role, while a business interface may be part of a business role (composition relationship).

The name of a business role should preferably be a noun.
