Business Layer Behavior Elements

Based on service-orientation, a crucial design decision for the behavioral part of the ArchiMate metamodel is the distinction between “external” and “internal” behavior of an organization.

The externally visible behavior is modeled by the element business service. A distinction can be made between “external” business services, offered to external customers, and “internal” business services, offering supporting functionality to processes or functions within the organization.

Several types of internal behavior elements that can realize a service are distinguished: a process view and a function view; two elements associated with these views, business process and business function, are defined.

A business interaction is a unit of behavior similar to a business process or function, but which is performed in a collaboration of two or more roles within the organization.

A business event is something that happens (externally) and may influence business processes, functions, or interactions.

In the Business Layer, three types of internal behavior element are defined: business process, business function, and business interaction.
