fundamental concepts or properties of an architecture entity in its environment embodied in its elements, relationships, and in the principles of its design and evolution

Architecture collection

group of architectures held by an organization that is subject to governance and management by the organization as a whole

Architecture description

work product used to express an architecture

Architecture entity

thing considered, described, discussed, studied, or otherwise addressed during the architecting effort

Architecture framework

conventions, principles and practices for use by architecture-related activities that have been established within a specific domain of application or community of stakeholders

Architecture view

interest in an entity relevant to one or more of its stakeholders

Enterprise engineering

discipline applied in carting out any efforts to establish, modify, or reorganize any enterprise

Enterprise model
