The Enterprise Systems Management (ESM) Requirements exist primarily because systems and networks are not currently self-healing. Given the broad scope of many of the referenced requirements, some provisions of some of these requirements may not be fully applicable to the IRS business systems modernization program. 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. The IRS has added custodial requirements to manage the receipt and disbursement, and related assets and liabilities, of taxpayer accounts. The IRS Technology blueprint is a living document that is continuously reviewed and updated as appropriate. Figure 107 depicts the Metabase high-level data model for storing the data contained in the enterprise’s architecture. The ETB reflects the vision, goals, and direction identified in higher level planning processes such as the IRS Strategic Plan, IRS Integrated Modernization Business Plan, IT Vision, business unit operational planning, and other sources. The Business Architecture comprises the following content areas: Business Services and Processes, including a description of an initial set of Business Services. Primary Stakeholders: IRS information technology management, analysts, and support contractors. The EA defines and describes allocation of functional and data requirements to systems. The Security Architecture models (work products) contained within the EA describe major security aspects of IRS logical business systems of the IRS Enterprise Target Architecture (ETA). Use of enterprise architectures in managing strategic change; Recently Added Books. The IRS EA presents a high-level view of how the Business Architecture can be used to support key roles in the planning, development, and managing the evolution of the IRS to meet its strategic goals and objectives. Information technology (IT) strategic planning 3. Security Processing Thread: shows the exercise of identification and authentication, access control, and audit mechanisms—both in the infrastructure and in an application—in a representative scenario. Finally, Technical Domains were recently introduced into the MV&S Framework. Twenty years ago, a new field was born that soon came to be known as enterprise architecture. Information returns (bulk file) – one for an account missing a tax return. The Security Requirements model specifies security requirements for the IRS Enterprise Target Architecture (ETA). These segments, or business domains, reflect a purely functional rather than organizational view of the business, and ensure that business priorities remain the focus of IRS IT investments. Process definitions that provide a robust description of processes and sub-processes, including key activities, data inputs and outputs, and security and privacy considerations. Provide a high-level assessment of the impact of the future state changes to the organization. 3 thoughts on “Technical Architecture Components” Pingback: Technical Architecture Component – Service Delivery Model « Enterprise Architecture, IT Strategy & Others. reusable set of well-defined functionality that encapsulates its implementation and exporting it as a higher-level interface The EA provides a security risk assessment model that supports the Enterprise target systems security architecture. Criminal Investigation: enforces criminal statutes of the Internal Revenue Code and related statutes. These can be enterprise wide or for that matter solely focus on a single line of business. The technology architecture model view of the ELC represents the physical platforms and technical infrastructure that supports the operation and use of applications and data in the IRS. Project Managers: support the following activities: Ensuring that key stakeholders (organizations and roles affected by project scope) are involved on the project team. 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 Functional Work Products define and mandate what the IRS Enterprise must do. Sensitivity Classification of ECDM Data Classes (part of the Data Requirements work product). Analysis Data. Provide high level strategic goals from which actionable goals can be derived. The Enterprise-wide Sequencing Plan describes how the existing and proposed investments align to the IRS vision and strategy. Enterprise Architecture directs all users of its products to develop, procure, maintain, or use Information and Communication Technology (ICT) ensure that these technologies provide access to information and data for people with disabilities. In addition, the blueprint is available online for all IRS employees and contractors with access to the intranet, and anyone may contact the EA team with proposed changes, which the EA team evaluates, prioritizes and incorporates as appropriate. 2.3.2 Components The concept of the components are defined as changeable goals, resources, processes and standards. The IRS Release Architecture (RA) is an IRS near-term IT plan encompassing all major and selected (strategic) non-Major IT projects planned for delivery within a sliding timeframe that includes the next three fiscal years. These definitions establish the enterprise-wide terms, nomenclature, and hierarchical structuring of locations, so that consistent names and meanings are used across the enterprise. Relationships between the functions and the data, depicted as objects in UML notation. The ETS summarizes the current state of the current production environment, documents challenges and goals for the IRS by business, technical or service domain, includes the defined portfolio of programs and projects for achieving the transition. These operational policies and procedures must be well defined and, in most cases, captured in the IRS Systems Standards Profile (SSP).

EAM translates the enterprise vision into venture and takes the enterprise … Functions that are depicted in activity diagrams using the Unified Modeling Language (UML) notation. Additional legislative requirements include Federal Acquisition Requirements (FAR) regulations.

Much of the detailed architecture guidance around the technology architecture is provided in the IRS TRM manual. The components … The core IRS business processes support the strategic goals as described in the Strategic Plan. EA Guidance documents include Enterprise Data Standards and Guidelines (EDSG), Service-Oriented Architecture (SOA) Guidance, .NET Guidance, and Design patterns. The following list includes all the Functional Work Products: Traceability of Data and Functional Requirements to Business Processes, Allocation of Functional and Data Requirements to Systems. The RA also documents dependencies between different projects and their releases. The product lifecycle status dates provide guidance for technology insertion, product deployment, and version updates as well as identifying when products are no longer supported and must be removed. the following list includes all the Security and Privacy Work Products: Federal Laws and Regulations Applicable to Security and Privacy (part of the Programmatic Requirements Work Product). Privacy Requirements Models: The primary purpose of the Privacy Requirements model is to specify privacy requirements for the IRS Enterprise Target Architecture (ETA). Arrays of management capabilities must be provided in order to achieve a "best-practice" ESM solution for the IRS. A logical data model is a complete account of the data required by an organization or business area. Security Risk Assessment: Estimates the relative degree of security risk associated with major target system components. An expanded view of the ArcGIS Server site includes content authors, … The ECDM is organized into three top-level subject areas, each of which also divides into three subject areas. Reporting Compliance: directs activities designed to strengthen compliance by identifying taxpayers non-compliant with reporting requirements that impact their tax liability or exempt status. The EA provides summaries of organization-level business concepts of operations (ConOps) that have been completed, processed, and approved for inclusion in the EA.
