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.
The Views described in DoDAF, including those that are legacy Views from previous versions of the Framework, are provided as pre-defined examples that can be used when developing presentations of architectural data.
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.
As the DM2 matures to meet the ongoing data requirements of process owners, decision makers, architects, and new technologies, it will evolve to a resource that more completely supports the requirements for architectural data, published in a consistently understandable way, and will enable greater ease for discovering, sharing, and reusing architectural data across organizational boundaries.
To facilitate the use of information at the data layer, the DoDAF describes a set of models for visualizing data through graphic, tabular, or textual means.
The DM2 defines architectural data elements and enables the integration and federation of Architectural Descriptions. The approach to the presentation of Architectural Description moves away from static and rigid one-size-fits-all templates of architecture portrayals for architects.
In addition to graphical representation, there is typically a requirement to provide metadata to the Defense Information Technology Portfolio Repository DITPR or other architectural repositories. These products are organized under four views:. 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.
These architecture descriptions may include families of systems FoSsystems of systems SoSand net-centric capabilities for interoperating and interacting in the non-combat environment. These views offer overview and details aimed to specific stakeholders within their domain and in interaction with other domains in which the dodat will operate. It broadened the applicability of architecture tenets and practices dodaff all Mission Areas rather than just the C4ISR community.
Department of Defense Architecture Framework
Dodaaf products focus on specific physical systems with specific physical geographical locations. Department of Defense for developing enterprise architecture has been debated:. DoD Business Systems Modernization: DoDAF dodaaf describes in the representation of the artifacts to be generated, but allows considerable flexibility regarding the specific formats and modeling techniques.
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 DoDAF deskbook provides examples in using traditional systems engineering and data engineering techniques, and secondly, UML format. For the purposes of architecture development, the term integrated means that data required in more than one of the architectural models is commonly defined and understood across those models.
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”. Product Descriptions” and a “Deskbook”. The concept of capability, as defined by its Meta-model Data Group allows one to answer questions such as:.
DoD weapons and information technology system acquisitions are required to develop and document an enterprise architecture EA using the views prescribed in the DoDAF. One of the principal objectives is to present this information in a way that is understandable to the many stakeholder communities involved in developing, delivering, and sustaining capabilities in support of the stakeholder’s mission.
Broad summary information about the whole enterprise e.
It establishes data element definitions, rules, and relationships and a baseline set of products for consistent development of systems, integrated, or federated architectures. United States Department of Defense information technology Enterprise architecture frameworks. This page was last edited on dldaf Octoberat Each view depicts certain dodqf of an architecture as described below.
The viewpoints categorize the models as follows: Information about how aspects of the enterprise are connected e. In other projects Wikimedia Commons.
Views Read Edit View history. Each viewpoint has a particular purpose, and usually presents one or combinations of the following: The Systems Viewpoint accommodates the legacy system descriptions.
In the past, decision-makers would look at DoDAF offerings and decide which were appropriate to their decision process. The actual sequence of view generation and their potential customization is a function of the application domain and the specific needs of the effort. 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.
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. The Systems Viewpointfor Legacy support, is the design for solutions articulating the systems, their composition, interconnectivity, and context providing for or supporting operational and capability functions. The three views and their interrelationships — driven by common architecture data elements — provide the basis for deriving measures such as interoperability or performance, and for measuring the impact of the values of these metrics on operational mission and task effectiveness.
These views are .202 for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabularstructuralbehavioralontologicalpictorialtemporalgraphicalprobabilisticor alternative conceptual means. Many times, these design products were not understandable or useful to their intended audience. In April the Version 1. 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 ddaf through viewpoints organized by various views.
It establishes a basis for semantic i. In addition, a note on system engineering is 2.02.

The developing system must not only meet its internal data needs but also those of the operational framework into which it is set. The OV provides textual and graphical representations of operational nodes and elements, assigned tasks and activities, and information flows between nodes.
Systems and services view SV is a set of graphical and textual products 2.022 describe systems and services and interconnections providing for, or supporting, DoD functions.
