The DoDAF provides an important basis for comparing architectures and identifying relevant interfaces. The DoDAF V1.5 SV products are: Technical standards view (TV) products define technical standards, implementation conventions, business rules and criteria that govern the architecture. Le Cadre est une structure simple et logique qui aide à organiser l'infrastructure d'information de l'entreprise. The Capability Models describe capability taxonomy and capability evolution. En plus de la représentation graphique, il y a une exigence particulière concernant la fourniture de métadonnées au référentiel Defense Information Technology Portfolio Repository (DITPR) ou d'autres référentiels d'architecture. One concern about the DoDAF is how well these products meet actual stakeholder concerns for any given system of interest. Le cadre DoDAF s'appuie sur des directives précises, notamment la stratégie des données réseau-centré (Net-Centric Data Strategy, NCDS, 2003). Un article de Wikipédia, l'encyclopédie libre. Les interconnexions entre systèmes définies dans OV sont décrites dans les vues systèmes SV. Conformance ensures that reuse of information, architecture artifacts, models, and viewpoints can be shared with common understanding. This new meta-model is called "DM2"; an acronym for "DoDAF Meta-Model". Cette description est présentée dans le volume III de la version 1.5 (métadonnées, registres de métadonnées). DoDAF has a meta-model underpinning the framework, defining the types of modelling elements that can be used in each view and the relationships between them. Évidemment l’objectif suprême est la réalisation d’applications opérationnelles. The DoDAF is brought to you by Visual Paradigm, a full-featured development platform. A category of persons defined by the role or roles they share that are relevant to an architecture. In the same period the reference model TAFIM, which was initiated in 1986, was further developed. Sinon, il y a un risque (vu dans au moins des initiatives d'architecture DoDAF) de construire des produits qui n'auraient aucun client. 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". The historical analysis shows that the use of DoDAF at the U.S. Department of Defense provides "the most spectacular example of progressing time and money investments in [enterprise architecture], but getting the same unsatisfactory results". La vision de la gestion des données décrite dans DoDAF est basée sur les trois éléments clés identifiés dans NCDS : DoDAF emploie la notion de communauté d'intérêt au sujet des groupes d'utilisateurs qui doivent échanger de l'information pour des objectifs, intérêts, missions, processus d'affaires partagés, et qui doivent pour cette raison disposer d'un vocabulaire partagé pour les informations échangées. Enter its alias and definition. Architectures exist for the purpose of achieving a well-defined system or more broadly for the enterprise, an integrated set of systems of systems (as defined in both the operational and system domains) for a specific time frame or time frames. The sequence of the artifacts listed below gives a suggested order in which the artifacts could be developed. Provide a basis for semantic precision in architectural descriptions to support heterogeneous architectural description integration and analysis in support of core process decision making. DoDAF Version 1.0, although outdated, has some good examples on how to construct AV’s, OV’s, and SV’s. Support discovery and understandability of EA data: Discovery of EA data using DM2 categories of information, Understandability of EA data using DM2’s precise semantics augmented with linguistic traceability (aliases). Core Architecture Data Model (CADM) is designed to capture DoDAF architecture information in a standardized structure. DoDAF est un cadre d'architecture dirigé par les données (exigence data-driven) : Les données sont définies par les objectifs de l'architecture et les exigences des processus de décision définies par la maîtrise d'ouvrage de chaque processus. It establishes a basis for semantic (i.e., understanding) consistency within and across Architectural Descriptions. The tutorial will provide an introduction to the DoD Architecture Framework ( DoDAF). Comme d'autres approches d'architectures d'entreprise, par exemple The Open Group Architecture Framework (TOGAF), DoDAF est organisé autour d'un référentiel partagé pour gérer les produits. How does a particular capability or capabilities support the overall mission/vision? Each of these three levels of the DM2 is important to a particular viewer of Departmental processes: The DM2 defines architectural data elements and enables the integration and federation of Architectural Descriptions. This includes the use of common data element definitions, semantics, and data structure for all architecture description entities or objects. The British Ministry of Defence Architecture Framework (MODAF) is an architecture framework which defines a standardised way of conducting enterprise architecture, originally developed by the UK Ministry of Defence.. In 2004 it was reported that "despite three years of effort and over $203 million in reported obligations, DoD’s architecture remains insufficiently defined, and the way in which the department makes business systems investments decisions remains largely unchanged". The actual sequence of view generation and their potential customization is a function of the application domain and the specific needs of the effort. In addition, DoDAF 2.0's specific goals were to: Establish guidance for architecture content as a function of purpose – “fit for purpose”. L'une des préoccupations sur DoDAF est la manière avec laquelle ces produits satisfont réellement les besoins des parties prenantes pour n'importe quel domaine d'intérêt. La structure du cadre d'architecture comporte deux couches : Les produits sont un moyen de visualiser l'architecture de données par des graphiques, des tables, des textes. Other derivative frameworks based on DoDAF include the NATO Architecture Framework (NAF) and Ministry of Defence Architecture Framework. This paper is an aggregation of information about DoDAF, serves as a high lever overview and introduction to DoDAF, introducing key terms, concepts and development methodologies, as well as its application in dealing with enterprise security planning related issues. It establishes data element definitions, rules, and relationships and a baseline set of products for consistent development … For this MBSE methodology is used. In regard to DoDAF V1.5 products, they have been transformed into parts of the DoDAF V2.0 models. la couche de présentation (produits et vues). [1], DoD Components are expected to conform to DoDAF to the maximum extent possible in development of architectures within the Department. On May 28, 2009 DoDAF v2.0 was approved by the Department of Defense. Savoir plus. What services are required to support a capability? 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. Wikipedia. DoD Architecture Framework (DoDAF) In the Department of Defense (DoD), the development of an architecture for a system is called the DoD Architecture Framework (DoDAF). Alors que ce cadre est clairement destiné à des systèmes militaires, il a des possibilités d'applications très larges dans les secteurs privé, public et du bénévolat dans le monde, et ne représente qu'un cadre d'architecture parmi d'autres. SV products focus on specific physical systems with specific physical (geographical) locations. A document that captures the information necessary to develop a proposed program(s), normally using an evolutionary acquisition strategy. L'OMG a démarré un projet visant à standardiser un profil UML pour des cadres d'architecture militaires : UPDM (UML Profile for DoDAF and MODAF). AcqLinks and References: [1] DoDAF Architecture Framework Version 2.02; DoD Architecture Framework Working Group Version 1.0, Volume 1: Definition and Guideline, 9 Feb 04 (Old Version) It establishes data element definitions, rules, and relationships and a baseline set of products for consistent development of systems, integrated, or federated architectures. Elles permettent de travailler ensuite sur quatre types de vues. The Open Group Architecture Framework (TOGAF) is an enterprise architecture methodology that offers a high-level framework for enterprise software development. DoDAF v1.0 a défini une liste de produits comme l'“ensemble minimum de produits requis pour satisfaire la définition d'un OV, SV et TV.” A capability thread would equate to the specific activities, rules, and systems that are linked to that particular capability. Les produits SV fournissent des descriptions graphiques et textuelles des systèmes et des interconnexions entre systèmes qui supportent les fonctions du département de la défense. Establish and define the constrained vocabulary for description and discourse about DoDAF models (formerly “products”) and their usage in the 6 core processes, Specify the semantics and format for federated EA data exchange between:architecture development and analysis tools and architecture databases across the DoD Enterprise Architecture (EA) Community of Interest (COI) and with other authoritative data sources. These products are organized under four views: Each view depicts certain perspectives of an architecture as described below. DoDAF V2.0 is published on a public website.[9]. DoDAF framework provide tools to describe the enterprise architecture – starting from capabilities, going to operational level and then to the system definition. What is our current set of capabilities that we are managing as part of a portfolio? Transition … [7] The current version is DoDAF 2.02 [8] It does this by enabling the capture and presentation of information in a rigorous, coherent and comprehensive way that aids the understanding of complex issues. But to build an architecture description that corresponds to ANSI/IEEE 1471-2000 or ISO/IEC 42010, it is necessary to clearly identify the stakeholders and their concerns that map to each selected DoDAF product. D'autre part, les services web et l'architecture orientée services, qui sont des catalyseurs des architectures réseau-centré, sont aussi intégrés dans cette vision. It was conceived as a way of providing a common means to specify systems for the Department of Defense (DoD) in its many facets and programs. In April 2007 the Version 1.5 was released with a documentation of "Definitions and Guidelines", "Product Descriptions" and "Architecture Data Description". Definition: Architecture development can be thought of as both a process and a discipline that aids the development of mission-effective systems. The DoDAF V1.5 defines a set of products, a view model, that act as mechanisms for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through graphic, tabular, or textual means. the Unified Profile for DoDAF-MODAF (UPDM) and ArchiMate. The current release is DoDAF 2.02. DoDAF versions 1.0 thru 1.5 used the CADM meta-model, which was defined in IDEF1X (then later in UML) with an XML Schema derived from the resulting relational database. The DoDAF specification is a recent upgrade to the 1997 C4ISR-AF specification. In addition, the multi-national IDEAS Group, which is supported by Australia, Canada, Sweden, UK, USA, with NATO observers, has launched an initiative to develop a formal ontology for enterprise architectures. The … This Architecture Definition Guide (ADG) provides a structured approach for populating a ™GENESYS software project with operational architectural information and producing information about the architecture following the Department of Defense Architecture Framework (DoDAF) requirements for viewpoint generation using the reports provided with GENESYS. DODAF stands for Department of Defense Architecture Framework. Only a subset of the full DoDAF viewset is usually created for each system development. Il est bien adapté à de grands systèmes dans une architecture intégrée (integrated architecture) complexe et des enjeux d'interopérabilité. The developing system must not only meet its internal data needs but also those of the operational framework into which it is set. The conceptual level or Conceptual Data Model (CDM) defines the high-level data constructs from which Architectural Descriptions are created in non-technical terms, so that executives and managers at all levels can understand the data basis of Architectural Description. The figure represents the information that links the operational view, systems and services view, and technical standards view. One note: while the DoDAF does not list the OV-1 artifact as a core product, its development is strongly encouraged. The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense, that provides structure for a specific stakeholder concern through viewpoints organized by various views. There may be more than one meaning of DoDAF, so check it out all meanings of DoDAF one by one. The tutorial will begin with a brief introduction to Enterprise Architecture . The DoD EA is defined as a federation of descriptions that provide context and rules for accomplishing the mission of the Department. DoDAF leads to identification what new systems (which does not exist) shall be designed, or which existing systems shall be improved. Otherwise there is the risk of producing products with no customers. The three views and their interrelationships – driven by common architecture data elements – provide the basis for [18] DoDAF proclaims latitude in work product format, without professing one diagramming technique over another. [6], 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. DoDAF in Visual Paradigm. From version 2.0, DoDAF has adopted the IDEAS Group foundation ontology as the basis for its new meta-model. The purpose of DoDAF is to define concepts and models usable in DoD's six core processes: Joint Capabilities Integration and Development (JCIDS), Planning, Programming, Budgeting, and Execution (PPBE). Basics of DoDAF and Architecture Frameworks; DoDAF 1.5; DoDAF 2.02; Introduction to DoDAF training course will teach you about architecting processes, methods, and thought patterns at a practical level. DoDAF leads to identification what new systems (which does not exist) shall be designed, or which existing systems shall be improved. Keep in mind that the abbreviation of DODAF is widely used in … Architectures are organized by mission areas. The Logical Data Model (LDM) adds technical information, such as attributes to the CDM and, when necessary, clarifies relationships into an unambiguous usage definition. f. Les propriétaires de processus de défense ( Defence Process Owners , DPO) ont la responsabilité de définir les frontières, le champ et les lignes directrices de leurs processus et de s'assurer que les interfaces avec d'autres processus sont gérées de manière appropriée. DoDAF is the overarching, comprehensive framework and conceptual model enabling the … These views are artifacts for visualizing, understanding, and assimilating the broad scope and complexities of an architecture … On peut considérer les produits DoDAF, ou au moins les trois vues, comme des points de vue ANSI/IEEE 1471-2000 ou ISO/IEC 42010. Represented in the DoDAF V2.0 DIV-1 Viewpoint. La vue OV fournit des représentations textuelles et graphiques des nœuds et éléments opérationnels, des tâches et activités affectées, et des flux d'information entre les nœuds. In simpler terms, integration is seen in the connection from items common among architecture products, where items shown in one architecture product (such as sites used or systems interfaced or services provided) should have the identical number, name, and meaning appear in related architecture product views.".
