In addition, DoDAF 2. It addressed the Deputy Secretary of Defense directive that a DoD-wide effort be undertaken to define and develop a better means and process for ensuring that C4ISR capabilities were interoperable and met the needs of the warfighter. It broadened the applicability of architecture tenets and practices to all Mission Areas rather than just the C4ISR community. This document addressed usage, integrated architectures, DoD and Federal policies, value of architectures, architecture measures, DoD decision support processes, development techniques, analytical techniques, and the CADM v1. In April the Version 1. The repository is defined by the common database schema Core Architecture Data Model 2.

It defines a way of representing an enterprise architecture that enables stakeholders to focus on specific areas of interests in the enterprise, while retaining sight of the big picture.
To assist decision-makers, DoDAF provides the means of abstracting essential information from the underlying complexity and presenting it in a way that maintains coherence and consistency.
Each viewpoint has a particular purpose, and usually presents one or combinations of the following: Broad summary information about the whole enterprise e.
Narrowly focused information for a specialist purpose e. Information about how aspects of the enterprise are connected e. However, it should be emphasized that DoDAF is fundamentally about creating a coherent model of the enterprise to enable effective decision-making.
The presentational aspects should not overemphasize the pictorial presentation at the expense of the underlying data. 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. The Systems Viewpoint , for Legacy support, is the design for solutions articulating the systems, their composition, interconnectivity, and context providing for or supporting operational and capability functions.
In the past, decision-makers would look at DoDAF offerings and decide which were appropriate to their decision process. Additionally, older version Architectural Description products were hard-coded in regard to content and how they were visualized.
Many times, these design products were not understandable or useful to their intended audience. DoDAF V2. The viewpoints categorize the models as follows: As illustrated below, the original viewpoints Operational Viewpoint, Systems and Services Viewpoint, Technical Standards Viewpoint, and the All Viewpoint have had their Models reorganized to better address their purposes.
The Services portion of the older Systems and Services Viewpoint is now a Services Viewpoint that addresses in more detail our net-centric or services-oriented implementations. DoDAF V1. The Systems Viewpoint accommodates the legacy system descriptions. The new Standards Viewpoint can now describe business, commercial, and doctrinal standards, as well as the technical standards applicable to our solutions, which may include systems and services.
The Operational Viewpoint now can describe rules and constraints for any function business, intelligence, warfighting, etc. Workshops have brought the Systems Engineering community and the architecture community closer together in defining the DoDAF architecture content that would be useful to the Systems Engineering process, and this has resulted in an understanding which the entire set of viewpoints and the underlying architectural data can be used in the System Engineering processes.
The approach to the presentation of Architectural Description moves away from static and rigid one-size-fits-all templates of architecture portrayals for architects. The term we have coined is "Fit-for-Purpose" presentation.
What is DoDAF Framework
Go to start of metadata The Department of Defense Architecture Framework DoDAF is an architecture framework for the United States Department of Defense DoD that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views. These views are artifacts for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabular, structural, behavioral, ontological, pictorial, temporal, graphical, probabilistic, or alternative conceptual means. This Architecture Framework is especially suited to large systems with complex integration and interoperability challenges, and it is apparently unique in its employment of "operational views". These views offer overview and details aimed to specific stakeholders within their domain and in interaction with other domains in which the system will operate. The DoDAF provides a foundational framework for developing and representing architecture descriptions that ensure a common denominator for understanding, comparing, and integrating architectures across organizational, joint, and multinational boundaries. It establishes data element definitions, rules, and relationships and a baseline set of products for consistent development of systems, integrated, or federated architectures.
