Department of Defense Architecture Framework - Version 2.0 Viewpoints

Version 2.0 Viewpoints

In DoDAF V2.0, architectural viewpoints are composed of data that has been organized to facilitate understanding. To align with ISO Standards, where appropriate, the terminology has changed from Views to Viewpoint (e.g., the Operational View is now the Operational Viewpoint).

All Viewpoint (AV)

Describes the overarching aspects of architecture context that relate to all viewpoints.

Capability Viewpoint (CV)

New in DoDAF V2.0. Articulates the capability requirements, the delivery timing, and the deployed capability.

Data and Information Viewpoint (DIV)

New in DoDAF V2.0. Articulates the data relationships and alignment structures in the architecture content for the capability and operational requirements, system engineering processes, and systems and services.

Operational Viewpoint (OV)

Includes the operational scenarios, activities, and requirements that support capabilities.

Project Viewpoint (PV)

New in DoDAF V2.0. Describes the relationships between operational and capability requirements and the various projects being implemented. The Project Viewpoint also details dependencies among capability and operational requirements, system engineering processes, systems design, and services design within the Defense Acquisition System process.

Services Viewpoint (SvcV)

New in DoDAF V2.0. Presents the design for solutions articulating the Performers, Activities, Services, and their Exchanges, providing for or supporting operational and capability functions.

Standards Viewpoint (StdV)

Renamed from Technical Standards View. Articulates the applicable operational, business, technical, and industry policies, standards, guidance, constraints, and forecasts that apply to capability and operational requirements, system engineering processes, and systems and services.

Systems Viewpoint (SV)

Articulates, for legacy support, the design for solutions articulating the systems, their composition, interconnectivity, and context providing for or supporting operational and capability functions. Note, System has changed in DoDAF V2.0 from DoDAF V1.5: System is not just computer hardware and computer software. System is now defined in the general sense of an assemblage of components - machine, human - that perform activities (since they are subtypes of Performer) and are interacting or interdependent. This could be anything, i.e., anything from small pieces of equipment that have interacting or interdependent elements, to Family of Systems (FoS) and System of Systems (SoS). Note that Systems are made up of Materiel (e.g., equipment, aircraft, and vessels) and Personnel Types.

The architectures for DoDAF V1.0 and DoDAF V1.5 may continue to be used. When appropriate (usually indicated by policy or by the decision-maker), DoDAF V1.0 and V1.5 architectures will need to update their architecture. When pre-DoDAF V2.0 architecture is compared with DoDAF V2.0 architecture, concept differences (such as Node) must be defined or explained for the newer architecture. In regard to DoDAF V1.5 products, they have been transformed into parts of the DoDAF V2.0 models. In most cases, the DoDAF V2.0 Meta-model supports the DoDAF V1.5 data concepts, with one notable exception: Node. Node is a complex, logical concept that is represented with more concrete concepts.
