The EA describes the future-state business processes that will support the IRS. The IRS Enterprise Technology Blueprint (ETB) articulates the envisioned long-range technology environment and describes how technology will be leveraged and deployed in support of the strategic IRS business direction. The Organization Model View consists of the following: Organization Descriptions identifies and describes the organizational entities that comprise the IRS. Matrices showing the relationship of processes to the organizations where the work is done, the roles that perform the work, and the location types where the work is accomplished. reusable set of well-defined functionality that encapsulates its implementation and exporting it as a higher-level interface Vendor product lifecycles change and the ESP alignment captures the information at approval but may be updated when needed or detected to synchronize with industry changes. 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. These can be enterprise wide or for that matter solely focus on a single line of business. 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 Business Work Products define all business-related aspects of the target state including business processes, organization, and location. From these sources, the ETB synthesizes an architectural vision that in turn serves as a touchpoint to guide more detailed program/project architectural planning, IT strategy initiatives, and other planning activities. Without enforcement of the EA, the IRS risks buying software and building systems that are duplicative, incompatible, and unnecessarily costly to maintain and integrate. Data Strategy: develops a coherent approach that will reduce data redundancy and the large operating costs caused by multiple, replicated or similar data stores. Authoritative data definitions and guidelines. Reporting compliance (remote assistance) requiring an exam. The Enterprise-Wide Sequencing Plan (EWSP) provides an evolving view of programs and projects and graphically depicts their relationships and impacts across the enterprise. Outline the key areas of change between the current and future states. The plan identifies the schedule for enterprise-wide management of multiple, concurrent, and interdependent development efforts. This hierarchical organization parallels the Enterprise Conceptual Data Model’s definitions of taxpayer and third party. The data architecture component of the EA addresses the key principles that affect the way that projects create and use data. The RA manages the complex relationship between projects and releases with planning domains. The IRS has added custodial requirements to manage the receipt and disbursement, and related assets and liabilities, of taxpayer accounts. In general, the IRS’ Enterprise context diagram does not describe interactions among the multiple roles of organizations unless those interactions are applicable to IRS business. It is divided into the Glossary defining all terminology and the Acronyms List defines acronyms used in the EA. The business data, summarized and reorganized for reporting and broad views of types and trends. Enterprise Architecture, of which the As-Built-Architecture (ABA) is one component, is mandated by a series of federal laws to maintain and report annually to OMB on their respective ABAs. Business Architects: support the following activities: Business process reengineering activities, and for planning Business Process Redesign Projects to ensure that project designs align with the business vision and supporting high level process designs and business services. The Systems Architecture is presented in two logical sections: The System Requirements items detail the needs identified during a comprehensive systems analysis. The purposes of this IRM are to: Define the EA and depict the key components of EA, Define how the EA fits within the concept of operations for the business. Enterprise architecture consists of the following three major components: hardware, software, and telecommunications … Which of the following is the unique identifying address for every, Put in order the steps of the process associated with a course. Ensure that projects take advantage of common infrastructure services in order to get maximum return on investment from a shared infrastructure environment, reduce redundant infrastructure, and enhance the use of common security, privacy, services management, and services delivery policies. 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 IRS EA discusses Enterprise System Management (ESM) as the basis for designing and deploying a complete systems management capability at the IRS. The higher level external entities are listed below: EE-1.2 – Organizational Taxpayers (not shown on context diagram), EE-2.0 – Third Parties (not shown on context diagram), EE-2.4 – Other Third Parties (not shown on context diagram), EE-2.4.1 – Other Taxpayer/IRS Intermediaries. Information architecture: identifies where and … IRS Organizations use the business ConOps as a strategic framework in order to express their future state vision. Enterprise architecture consists of the following three major components, 48 out of 51 people found this document helpful, Enterprise architecture consists of the following three major, hardware, software, and telecommunications, business strategy, business goals, and objectives, application architecture, information architecture, and technical architecture, process modeling, process documentation, and business process reengineering, Which of the following is defined as fully understanding the goals of, a process and then dramatically redesigning it from the ground up to. This discussion supplies guidance regarding: Mechanisms deployed to provide ESM core functions. This section includes the scope, purpose, and objectives of Enterprise Architecture.

To demonstrate cross-business process integration. STM is essential to the successful alignment of individual products, standards, and technologies to the Target Enterprise Architecture. Internal Management: manages IRS human capital and financial accounting. Allocation of Security Mechanisms to System Components (part of the Security Architecture work product). It can be a tax service or a service that provides a tax product. The ABA allows Business Analysts and Information Technology (IT) professionals to view the CPE from both technical and business perspectives using IRS’ Enterprise Life Cycle’s (ELC) Six Domains of Change, to see interrelationships between technological and business domains, and get information necessary to make informed decisions. EA describes programmatic requirements as those based on security and privacy; the IRS; and all agencies. System complexity—Organizations were spending more and more money building IT systems; and 2. The first one is fiSystem Portalfl, which is an interface between users and the system objects. All IRS organizations that own or manage IT applications in the CPE are required to provide updates to the EA organization so that the ABA remains updated and is as complete as possible in order to answer external data calls for application-related information. The Application and Technology in EA covers the following areas: The technology architecture of the EA represents the hardware, system software, and network components needed to support the implementation of business system applications and application data. It draws its base data from the Enterprise Transition Strategy (ETS). 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). 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 matrix is provided to assist in business case development and provide stronger justifications of proposed improvements to IRS business processes by demonstrating a clearer line of sight to IRS business results. Security Categories of ETA Business Processes. IRS business processes are associated with the specific process / role matrices that accompany each business process area description. IRS business processes are associated with the specific Location Types at which they are performed in process / location type matrices. There are two such models: Allocation of Security Mechanisms to System Components: allocates the security mechanisms specified in the Security Requirements model to system components identified in the IRS Logical Business Systems / Allocation of Functional and Data Requirements to Systems model. The allocation of ESM mechanisms to system components. The IRS EA provides the blueprint for modernizing the IRS.

The IRS EA describes processing threads that are used to demonstrate how system software applications are involved in executing high-level business processes. Audience: (1). Five categories of performance requirements are specified, including Enterprise Workload, Enterprise Response Time, Enterprise Reliability, Maintainability, and Availability Requirements. Builders/Architects - EA Program, IRS developers, and contractor developers. In addition to that model, a supporting model is also included highlighting the traceability of Privacy and Technical Security Requirements to Business Process Security and Privacy Considerations: tracing privacy requirements models to privacy considerations of target business processes. In addition, EA manages performance, functional, and system management requirements and provides traceability of data and functional requirements to business processes. The external entities are organized hierarchically with top-level entities broken down into second-level and sometimes third-level entities. To demonstrate alignment and support of the FEA Performance Reference Model. The ABA represents the IRS' Current Production Environment (CPE) with business applications, external systems, and external trading partners. Customer Service: provides tax law and compliance assistance, taxpayer education, and taxpayer account, refund, and notice inquiries. Figure 107 depicts the Metabase high-level data model for storing the data contained in the enterprise’s architecture. Functions that are organized primarily by the business areas described in functional requirement. This preview shows page 3 - 6 out of 7 pages. Security Risk Assessment: Estimates the relative degree of security risk associated with major target system components. This supports a services approach that complies with the layered approach specified in the TRM. Authors call it enterprise … These critical services are addressed by the service domains, and include cross-cutting data, infrastructure and security services as well as common business functions that can be leveraged to support business domains. The Enterprise Standards Profile is primarily of interest to readers involved with design, development, and product selection. The EA provides summaries of organization-level business concepts of operations (ConOps) that have been completed, processed, and approved for inclusion in the EA. 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. Selecting applications software to support business process and service design.s. In the IRS EA, logical systems are defined across the Enterprise. The Zachman Framework for Enterprise Architecture -- which covers six architectural points as well as six primary stakeholders that aid in defining and standardizing IT architecture components. Privacy Considerations of Target Architecture Business Processes. The description is divided into following set of document segments, which are defined according to the IRS layers and interfaces: The IRS EA provides an overview of the Technical Architecture from the perspective of the three technical views in the Enterprise Lifecycle (ELC) methodology. It is useful for this discussion to define three hierarchically related aspects of strategic planning (see Figure 2.2): 1. The Enterprise Systems Management (ESM) Requirements exist primarily because systems and networks are not currently self-healing. The vision, themes, and enterprise technology direction in the TR is used by the IT investment planning team to evaluate the alignment of IT investment proposals with the broader enterprise business and technology decisions. The IRS Target Architecture defines the desired future state of the IRS Enterprise. Enterprise Business Concept of Operations, Process Thread Performance Model (integrated within Business Process Model), Process/Organization Matrices (integrated within Business Process Model), Process/Role Matrix (integrated within Business Process Model), Process/Location Type Matrix (integrated within Business Process Model). The key role of an ERP system is to provide support for such business functions as accounting, sales, inventory control, and production. The JFMIP states that Effective financial management depends upon appropriate control of business transactions, in accordance with internal control standards, and recording business event information in a manner that satisfies multiple users and uses. These definitions establish the enterprise-wide terms, nomenclature, and hierarchical structuring of locations, so that consistent names and meanings are used across the enterprise. 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. The Enterprise-wide Sequencing Plan describes how the existing and proposed investments align to the IRS vision and strategy. The IRS EA presents programmatic requirements for the IRS Business Systems Modernization Program. The ESP focuses on the functionality of standards and approved products. Enterprise architecture consists of the following. 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. There are three primary uses supported by the ETB. A logical data model is a complete account of the data required by an organization or business area. However, regardless of the breadth of management products that are selected for deployment at the IRS, all must conform to a common set of operational policies and procedures, and all must be very closely integrated. Privacy Requirements Models: The primary purpose of the Privacy Requirements model is to specify privacy requirements for the IRS Enterprise Target Architecture (ETA). However in many cases, the performance goals specified by these matrices are incomplete. 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. Other Models of the Target Architecture Privacy View: The privacy architecture view of the Target Architecture consists of other models besides the two named just above. These two glossaries are intended to be mutually exclusive. The Business Process Model includes: Automated and/or manual functions that develop the business processes described in Business Processes. Outline potential areas of process change. Infrastructure architecture. Each … The focus of the Technical Services Domain is the delivery of base products and services (shared resources that can be used on demand by many different applications) that affect the development, operations, and maintenance costs of systems; the time necessary to develop and deploy new or revised capabilities; the flexibility and capability to resource-development efforts; and the effective operational performance of these systems and their ability to provide the desired business results. The Business Process Model includes: Automated and/or manual functions that develop the business processes described in Business Processes. If a term does appear in both, the definition in the Glossary of IRS Business Terminology has precedence. Functions that are organized primarily by the business areas described in Business Processes. Cybersecurity: ensures compliance with federal statutory, legislative, and regulatory requirements governing confidentiality, integrity, and availability of IRS electronic systems, services, and data in accordance with FISMA. These problems, first recognized 20 years ago, have today reached … Ensuring that their project scope is unique and well understood by the project team, key stakeholders and sponsors. Ensuring that their business results are consistent with the business services offered, business process visions, and supporting high level process designs. The IRS EA defines several key concepts, in order to provide a better understanding of how and where custodial financial controls fit into the EA. The following list includes all the Technology Work Products: The Security and Privacy Work Products are a subset of the Systems Architecture work products. Security Categories of ETA Business Processes: Identifies FIPS 199 security categories for target business processes. These are then used to develop a set of abstract systems, which in turn define a set of conceptual target-state applications that manage enterprise data on enterprise-approved technology platforms. Defines the ERP architecture through the physical components of hardware, software, data and networking. The IRS EA defines both an Enterprise Conceptual Data Model (ECDM) and an Enterprise Logical Data Model (ELDM). The ESP presents status about standards and approved products. The EWSP identifies the schedule for enterprise-wide management of multiple, concurrent, and interdependent development efforts. The Business Process Model includes: Process hierarchies in the form of decomposition diagrams that show structure. The IRS mission and strategic goals are implemented through a five-year plan that drives information technology investment decisions based on priorities around modernizing front-line tax administration and supporting technical infrastructure. 2.3.2 Components The concept of the components are defined as changeable goals, resources, processes and standards. 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 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. This tutorial describes how usages of Software Components are packaged and deployed into Application Deployments in Essential Architecture Manager. Enterprise Architecture (EA) provides insight into organizations’ business and IT components and how these are interconnected. As these are Software Component… (1) All of the existing content, last updated in 2009, has been revised and replaced. Enterprise architecture management (EAM) is a structured approach that an enterprise uses for creating, managing, and using enterprise architecture to align business and IT. Business investments and resources are also fully aligned with the approved segment architecture. The Data Work Products define what data must be processed and stored by the IRS Enterprise, how it is structured and interrelated, and how it will be stored as listed in the following: The Performance Work Products define how well the IRS Enterprise must perform as listed: The Technology Work Products define the technical infrastructure needed to support the Functional, Data, and Performance Work Products. To demonstrate alignment of major IT investments with the FEA Service Component Reference Model (SRM). As appropriate, Enterprise Functional Requirements and Data Requirements are allocated to these systems. A data server to store application data … These entities are organized hierarchically with summary-level entities sometimes broken down into second- and even third- level entities. IRS business processes are associated with the specific IRS Location Types at which they are performed in Process / Location Type. The Enterprise Architecture Requirements initiative include programmatic, security, and privacy requirements. 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. The EA is essential to the successful evolution of IRS IT systems and the Agency’s necessary accommodation of periodic business changes, and its development of modernized systems. EA continuously assesses the IRS landscape and plans and proactively identifies and validates needed changes. The ESM solution deployed at the IRS must be flexible enough to adapt to a wide variety of operational models. (3). EA leverages existing systems, as defined in the As-Built Architecture, and new development to build capabilities, optimize capacity, manage program costs, and deliver business value on an incremental and frequent basis. A relational database hosting Appian internal data and metadata, plus any additional relational databases hosting Appian business data. The common architecture decisions for technology, application, and data model views (that is, the Technical Architecture) are documented in the Application Architecture (Official Use Only), Data Architecture, and Conceptual Technology Architecture models provided by the EA. In its framework for Federal Financial Management Systems, the JFMIP states that “Effective financial management depends upon appropriate control of business transactions, in accordance with internal control standards, and recording business event information in a manner that satisfies multiple users and uses. The principles contained in the EA are statements describing the preferred architectural direction for the IRS. These scenarios were developed in response to requests from the business community to meet two objectives: To demonstrate that the business processes outlined in the EA provide adequate coverage for the business functions under a variety of business conditions. Each release architecture specifies the state of the enterprise after the system deployments planned for a fiscal year. Arrays of management capabilities must be provided in order to achieve a "best-practice" ESM solution for the IRS. Capacity and performance planning To plan your deployment capacity and … Introducing automation to improve upon manual activities and processes. The security architecture view of the Target Architecture consists of other models besides the three named just above. 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. (1) This transmits revised IRM 2.15.1, Enterprise Architecture (EA), Enterprise Architecture (EA) Overview. The Enterprise Transition Strategy (ETS) describes the overall IRS vision and strategy, and how existing and proposed investments align to it. This translates into specific focus areas – delivering applications for the IRS, delivering the filing season, and maintaining legacy technology systems. Consolidating or standardizing similar processes and services – as appropriate. While the first model shows the form of the systems security architecture, the second model shows something of its behavior. The field initially began to address two problems: 1. The EA defines and describes allocation of functional and data requirements to systems. The Location Type Definitions identify and classify all of the distinct types of locations where IRS conducts business (directly or indirectly) or where critical functions are performed in support of IRS business or technical operations. Software Components are deployed to Application Deployments in the Physical View of the Application Layer in the Essential Meta Model. Conducting compliance certifications – by ensuring project deliverables and designs align with the vision and high level designs contained in the Business Architecture. Analysis Data. Criminal Investigation: enforces criminal statutes of the Internal Revenue Code and related statutes. It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. The focus is on functional and physical locations that are durable over time. The RA also documents dependencies between different projects and their releases. In addition to that model, EA specifies security requirements for traceability of Privacy and Technical Security Requirements to Business Process Security and Privacy Considerations and the crosswalk of NIST SP 800-53 and ETA Security Requirements. ERP … The key standards component is the Enterprise Standards Profile (ESP) database. It also includes interfaces, key attributes, and information related to Privacy and Civil Liberties Assessments. Ensure that projects that develop application services can make certain of these services available to other IRS business systems in order to promote re-use of application functionality and to eliminate duplication of effort and redundant data.
