DoD Information Enterprise Architecture Version 2.0specific focus area. These RAs, along with general DoD IEA information, provide the basis forcompliance with the DoD IEA. A content navigation support tool, referred to as the IEAInformation Reference Resource (I2R2) is also being developed to accompany the DoD IEAv2.0. The I2R2 consolidates and organizes compliance and guidance information by documenttype, capability type, and other categories to help understand compliance and analysis.Future increments of the DoD IEA will continue to enhance and refine content, as necessary, todescribe changing enterprise strategies and priorities; update relationships, application, and use;and clarify compliance criteria.1.1 PurposeThe purpose of the DoD IEA v2.0 is to provide a strategic level architecture to stakeholders. TheDoD IEA will be extended with detail by developing reference architectures. The content of theIEA and the RAs will be provided in formats supporting different stakeholder needs, donethrough a set of tools that will promote the use of the IEA and RA content for decision-making.These tools focus on the navigation, integration, and use of architectural data and analysis. Theyinclude architecture development tools such as System Architect; data navigation, integration,and use tools such as the I2R2 and Enterprise Elements. The DoD IEA impacts IT efficienciesby:• Establishing the authoritative vision for the DoD IE• Providing the technical enterprise direction necessary to implement the DoD IE vision• Providing context and guidance to critical Department-wide efforts such as the ITEnterprise Strategy and Roadmap (ITESR) and the IT Effectiveness effort• Providing prescriptive architectural content for DoD compliance processes and tools• Providing direction to IT stakeholders in formats supporting their needs through a set oftools that promote IE content-based decision-making1.2 GoalsThe DoD IEA v2.0 provides a means to ensure that all applicable DoD programs, regardless ofComponent or portfolio, align with the DoD IE vision and enable agile, collaborative net-centricinformation sharing. The goals of the DoD IEA v2.0 are to:• Provide the basis for an IE that better enables Warfighting, Business, and DefenseIntelligence domain operations• Provide a traceable line-of-sight from strategic guidance to solution architectures• Provide direction for proper planning for transforming the DoD IT landscape• Enable more informed acquisition of resources• Effectively operate the resulting IT environment2
DoD Information Enterprise Architecture Version 2.0In achieving these goals, it is necessary to describe and institutionalize the capabilities andservices required to meet warfighting operational requirements. To do this, the DoD IEA mustprovide information and descriptions, useable in analysis, that answer stakeholder questions.1.3 ScopeThe DoD IEA v2.0 expands, enhances, and evolves the description of the future IE and supportsDoD IT investment decisions based upon tiered accountability and federation considerations.The Department’s approach to net-centric transformation in this environment is guided by theconcepts of Tiered Accountability and Federation. Tiered Accountability aligns responsibility fordecision making and execution across the Department. Federation ensures decision makers andimplementers understand and align programs and capabilities horizontally and vertically acrossall these levels. A federated approach allows each element (in accordance with its Titleauthority) to leverage the decisions and services of other elements. Each element governs theareas, for which it is responsible, and should acknowledge and maintain consistency withguidance from higher level reference architectures. To improve understanding, Departmentarchitectures depict department-wide rules and constraints while Component architectures depictmission-specific services and capabilities and Solution architectures depict solutions thatconform to higher rules and constraints. The following areas are described in the DoD IEA v2.0:• Operational context for the IE• A traceable line-of-sight from strategic guidance to solution architectures.• IE vision and the capabilities needed to achieve the vision• Activities, rules, services, and standards for providing the IE capabilities• Refined compliance criteria for the DoD IEAThese descriptions are provided through a robust set of architecture views including All Views(AV), Capability Views (CV), Operational Views (OV), Service Views (SvcV), and StandardsViews (StdV). The DoD IEA informs and constrains enterprise-wide decisions that influence therequirements for systems and solutions with a focus on the following three primary sets ofcustomers:a. Architects: Includes architects across capability portfolios, Federal Agencies and DoDComponents. They use the DoD IEA in the development of architectures to align touchpoints and boundaries, as well as to identify interoperability gaps and the requirementsfor federation. DoD architectures, including the DoD IEA, are collectively known as thefederated DoD Enterprise Architecture (DoD EA). This means that DoD Architecturesare autonomous, but they apply common services, processes, and standards to ensureinteroperability. The components of the DoD EA include strategic guidance such aspolicy; the DoD Architecture Framework (DoDAF); the OMB FEA reference models;tools such as repositories and registries; and the set of federated Command/Service/Agency (C/S/A) enterprise, reference, and solution architectures.3
