Architecture Framework l “An architecture framework is a tool… It should describe a method for designing an information system in terms of a set of building blocks, and for showing how the building blocks fit together. It should contain a set of tools and provide a common vocabulary. It should also include a list of recommended standards and compliant products that can be used to implement the building blocks.” [TOGAF 8, OpenGroup] l The Department of Defense (DoD) Architecture Framework (DODAF) – 4 Defines a common approach for describing, presenting, and integrating DoD architectures DoD Architecture Framework 1.0 l The Department of Defense (DoD) Architecture Framework (DODAF) – – Defines a common approach for describing, presenting, and comparing DoD architectures Facilitates the use of common principles, assumptions and terminology l The principal objective of the Framework is to – 5 Ensure that architecture descriptions can be compared and related across organizational boundaries, including Joint and multi-national boundaries DODAF Basic Principles - An Integrated Architecture with Three Views Activities/ Tasks Operational View Operational Elements • • • W • W ha In ho t N • Re form Do eed Sy qu at es s t th s ire ion It o B Inf e A tem dt E eD or ct s t o G xc m ivi ha on ha ati tie t e e t It ng on s a Su e D s Ex nd pp o ne or ch t Data Flow Systems X Y Systems View X Standards Y Communications Rules Technical Standards View Z Relates Systems and Characteristics Yto Operational X Needs 6 ility tab or s pp itie Su bil gy pa an ge s Information Flow lo a al ts s no l C on en tie ch ica ati m ili Te chn er ire pab sic Te Op qu a Ba w Re nd C • Ne a • Identifies What Needs To Be Done And Who Does It • Technical Standards Criteria • Specific Capabilities Governing Interoperable Required to Satisfy Information Exchanges Implementation/Procurement Prescribes Standards and Conventions of the Selected System Capabilities Conventions Architecture Framework Views and Viewpoints* TOGAF Views 7 Kruchten’s 4+1 Architecture views RM-ODP Viewpoints DoD Framework Views & Applicable Products View Concerns Business Architecture View Scenarios Enterprise Viewpoint Operational View Stakeholders, Business Process, And Information Flow Models Describes Enterprise and required capability from the Stakeholder’s perspective Data Architecture View None Information Viewpoint Operational/ Systems View Logical Data Models, Physical Schema Describes information and data needed to provide capability Applications Architecture View?

Federal Architecture Frameworks DODAF TEAF General Description Defines a common approach for describing, presenting, and integrating DoD architectures Defines a common approach for describing, presenting, and integrating Treasury/bureau architectures Provides ability to look across federal government projects and identify opportunities to collaborate, consolidate, and identify Information Technology (IT) investments How widespread is its use? Required across DoD • Adaptations in use by NRO, NATO, multiple foreign countries • In use for eight years • Influenced other Frameworks Was used by Treasury and Bureaus for 3 years. “No longer supported” Embryonic, still evolving How much guidance is there for the Architect? • • Provides categories into which aspects of individual project proposals can be mapped • • 9 Prescribes a very highlevel process for getting started Products very specific for detail work New “Desk Book” (Includes “As-Is” to “ToBe” transition strategy, example processes, reference resources) • • Provides more details than FEAF Most products borrowed from DoD FW Adds some IA products to the DoD set FEA Reference Models Federal Architecture Frameworks DODAF 10 TEAF FEA Reference Models Structure Three Views — Operational, Systems, Technical — with various model types assigned to Views Zachman-like matrix Functional, informational, organizational, and infrastructure columns DODAF-like products, Comprised of five reference models — Performance, Business, Service Component, Technical, and Data Reference Models Integration within the Framework Explicit connections between elements across products Explicit connections between elements across products • Business Reference Model (BRM) linked to Budget Function Codes, which can serve as useful starting point to align IT investments to BRM • Simple association rules between models, e.g., each Line of Business (BRM) should have an associated performance measure from the PRM Level of detail addressed Level of detail captured in each product left to Architect in accordance with purpose and scope of architecture Level of detail captured in each product left to Architect in accordance with purpose and scope of architecture Simple hierarchical decomposition within each reference model DODAF Applicability Beyond DoD © 2002 The MITRE Corporation.

Areas for Possible Research l Validate and Clarify the information definitions provided by the DoDAF – – To capture the architecture data elements (object and relationships) described by DoDAF Use DoDAF definitions to define an object model l Validate and Clarify the notation definitions intended by DoDAF – Adjust the object and relationship definitions to include graphics (e.g., modeling notation) and/or formatting characteristics that are required to be common l Facilitate the common usage of such a model – – 40 Define an ontology: identify the generalizations / specializations (supertypes / subtypes) that are appropriate Provide clear, concise descriptions for all the data elements Areas for Possible Research (Cont’d) l Benefits - A DODAF model will: – Provide a common set of objects and relationship definitions (requirements) that can be used by tool vendors to supply software tools that support the development of DoDAF-Compliant architectures – Provide a common set of objects and relationship definitions against which a standard interface can be defined to: v v 41 Enable the sharing of architecture model / products between different tools Enable the implementation of a common repository for architecture data References 42 l ANSI/IEEE 1471-2000 Recommended Practice for Architectural Description of Software-Intensive Systems l Clements, P., F.
