The Enterprise View addresses the relationships between organizations and users, and the roles those entities play in the delivery and consumption of ITS services. Relationships between entities are dependent on the roles those entities take in the delivery of user services.
The building blocks of ARC-IT's Enterprise View are Enterprise Objects that interact to exchange information, manage and operate systems beyond the scope of one organization. The Enterprise View focuses on the relationships between those Enterprise Objects, but also defines how Enterprise Objects interact with Physical Objects, which appear in the Enterprise View as Resources.
The relationships between Enterprise Objects are organized as various types of Coordination: an agreement or contract intended to achieve the common purposes necessary to implement and deliver an ITS service. The relationship between an Enterprise Object and a Resource is a Role: owns, operates, develops, installs, maintains, etc.
In version 8.1, the Enterprise View defines the various roles and relationships that support aspects of the development, installation, operations and maintenance phases of the system life cycle. The enterprise viewpoint specification provides the background for enterprise relationships in the United States, and defines the graphical language used within SET-IT to illustrate project-level enterprise relationships.
