A Business Interaction model does not concentrate on the definition of the organizational units, but rather on the communication and passing of goods and information between political boundaries. The purpose of a Business Interaction Model is to understand the interfaces between these political islands, and between the business and its environment.

Business interaction models can be partitioned into business processes. These process views can automatically populate the people aspect of standard Workflow models for more detailed activity-level analysis.

Communication Modeler

Communication models specify the important communications that exist among organizational components (markets, organizations, roles and people), process components (business domains, processes and activities), physical assets (locations, facilities and equipment), and system components (systems and stores).

Included in this set of communication modelers is an overall Communication Modeler, Location Modeler, System Modeler, and Storyboard (or User Interface) Modeler. These models, along with their supporting components, provide the means to define complex communication patterns and networks that support the enterprise.

Organization Modeler

The Organization models define and structure the organizational components of the enterprise along with their fundamental inter- and intra-business interactions. The organizational components supported are markets, organizations, roles, and people.

Organization models specify the vertical organizational hierarchy or reporting structure of an enterprise or a portion of the enterprise. Business Interaction models provide a horizontal view of peer organizational components along with the named interactions that exist between the organizational components.

Location Modeler

A Location model is a hierarchy that organizes the locations, facilities, and equipment discovered for a business domain. A number of Location models may be created for the business domain, categorized by subject.

One model may organize the facilities of the business. For example, the highest location may be a business site, which contains specific buildings, which contain specific floors, which in turn contain specific work areas, etc. Another Location model may relate customer locations. For example, a business' markets may be organized into countries, which in turn contain specific regions, which contain specific states, etc.

System Modeler

A System model defines a decomposition structure of systems, subsystems, and user interfaces. A system is defined to be a network of automated components that work together to provide functionality that satisfies specific requirements. The system designed to support functional business requirements is frequently referred to as an application system.

Systems can be viewed as software that consists of a coordinated set of distinct (as seen from other users’ perspectives) functions. Accordingly, systems can range from a massive network supporting multiple organizations to a system that is a functional part of another system.
