Ensure a common approach for understanding, comparing, and integrating architectures, Act as a key enabler for acquiring and fielding cost-effective and interoperable capabilities, Align with architecture references produced by international standard bodies, produce standard DoDAF / MODAF / NAF products as well as commercial extensions, leverage cross-industry, standards-based approaches (e.g., MDA, UML, SysML) to enhance tool and architecture data interoperability, MDA foundation enables UAF to evolve with DoDAF v2 and beyond (i.e. 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. All Viewpoint (AV) – Describes the overarching aspects of architecture context that relate to all viewpoints. As such, systems should be designed to automate the process, not to encode the organizational responsibilities, to keep these two independent of each other.

This ‘grid’ structure, represents the various ‘subjects of concern’ (rows) and ‘aspects of concern’ (columns), as shown below: The Unified Architecture Framework® (UAF®) is based on the Unified Profile for DoDAF and MODAF™ (UPDM™).
