The three-dimensional framework … ERP vendors, including SAP, Oracle, and Microsoft… Data models of more than a few data classes are organized as a hierarchy of subject areas, each more narrowly defined than the subject area containing it, until they are small enough to allow comprehension of the entire subject area in a diagram or two. It also includes interfaces, key attributes, and information related to Privacy and Civil Liberties Assessments. The goals of defining these common decisions are to: Ensure that projects deliver functionality that can be integrated and maintained in the IRS environment. Security Requirements: Specifies security requirements–particularly, technical (that is, information technology [IT]) security requirements–for the Target Architecture, Traceability of Privacy and Technical Security Requirements to Business Process Security and Privacy Considerations: Traces the security requirements of the previous model to what are called the security considerations of target business processes, Crosswalk of NIST SP 800-53 and ETA Security Requirements: A crosswalk of the Target Architecture technical security requirements and the controls specified in NIST SP 800-53, Recommended Security Controls for Federal Information Systems, Revision 1, Other Models of the Target Architecture Security View.

It involves firm leadership, a complete knowledge of organizational structure, a … Producing an Enterprise-wide solution provides for a high degree of flexibility with regard to implementing evolutionary changes to the operational model with the least amount of disruption to service levels. The vision and strategy framework is built on the functional segmentation of the IRS, representing the core mission business functions that directly relate to front-line tax administration. The Enterprise-Wide Sequencing Plan (EWSP) provides an evolving view of programs and projects and graphically depicts their relationships and impacts across the enterprise. It uses EA methods and visualizations to depict the complex interrelationships between the envisioned business capabilities, data, applications and systems, technologies and infrastructure. The OEAF: Information Architecture Domain consists of the following components: The ETS also provides an organization-wide view of programs and projects across the agency, giving leadership the visibility to use the EA for organization-wide planning.

Enterprise Architecture Planning model consists of four levels: Level 1 - getting started : This layer leads to producing an EAP workplan and stresses the necessity of high-level management commitment to support and resource the subsequent six components (or steps) of the process. This model also indicates the FIPS 199 security category of Taxpayer data and Personally Identifiable Information (PII). Primary Stakeholders: IRS information technology management, analysts, and support contractors. Information returns (bulk file) – one for an account missing a tax return. Infrastructure architecture. Two risk estimates are given: (1) for the component unprotected by any security mechanisms and (2) for the component protected by the security mechanisms described in the Allocation of Security Mechanisms to System Components model of the Security Architecture. Knowledge Management (KM) Data. Authoritative data definitions and guidelines. The Security, Section 508, and Privacy Work Products are a subset of the Systems Architecture work products. Taken as a whole, these Work Products define the measures necessary to protect sensitive IRS assets, including taxpayer information. While the first model shows the form of the systems security architecture, the second model shows something of its behavior. Federal Enterprise Architecture is OMB policy on EA standards. IRS Organization Descriptions, which are part of the IRS EA Organization Model View, identify and describe the organizational entities that comprise the IRS. This section includes the scope, purpose, and objectives of Enterprise Architecture. As such, these Work Products are the core of the IRS EA.

These 508 standards, requirements, and regulations include the provisions for building 508-specific technical requirements, functional performance criteria, and both system and user interfaces into the design. The need for systems management is not limited to any specific platform, system, or application types, but rather, extends to all platforms, systems, and applications that are deployed at the IRS. Functions that are depicted in activity diagrams using the Unified Modeling Language (UML) notation. The web-based Change Request management application is accessed by IT partners to modify the ESP. The RA provides an integrated view of the IRS-wide consolidated IT project portfolio and its effect on the Enterprise Architecture and IT environment. Data architecture in the EA covers the following areas: Data modeling, categorization and relevant subject areas. Segment architecture is developed to support a clear and concise value proposition linked to the agency mission, as well as to its strategic goals and objectives. To achieve this objective, segment architecture is used to identify the enterprise segments and to link enterprise-level planning with the development and implementation of solution architecture. The IRS EA describes processing threads that are used to demonstrate how system software applications are involved in executing high-level business processes. Overview. It encompasses three tiers of the distributed computing architecture and includes data and voice networks, call centers and video communication and other physical components of IRS' IT environment.

The IRS EA captures the current state of the IRS Enterprise in an As-Built Architecture, defines the desired future state of the IRS Enterprise in a Target Architecture, and defines a plan for getting from the current state to the desired future state in an Enterprise Transition Plan. The EA defines and describes allocation of functional and data requirements to systems. The EA is composed of the following three major components and many sub-components within each major component: As-Built Architecture including all information technology applications. The IRS EA describes high-level system performance requirements. These key concepts are: The enterprise context diagram profiles the business environment in which the IRS operates. Third party support also is addressed. This reference architecture uses the WorldWideImporterssample database as a data source. The scope encompasses the entire IRS Enterprise, including advisory functions, such as Chief Counsel and the National Taxpayer Advocate, as well as all Operational Support components. The multi-tier approach includes web, application, and database tiers of servers. To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture … Filing and payment compliance for an LMSB tax return. STM identifies, approves, and manages the technology products, service contracts (including cloud), and standards that define the business initiatives affecting IT.

This translates into specific focus areas – delivering applications for the IRS, delivering the filing season, and maintaining legacy technology systems. The Enterprise Systems Management (ESM) Requirements exist primarily because systems and networks are not currently self-healing. A logical data model is a complete account of the data required by an organization or business area.
