The EA describes linkages between every Tax Administration Services, Support Delivery of Services and Internal Management of IRS Resources business process as defined in the End-to-End Business Process Views. reusable set of well-defined functionality that encapsulates its implementation and exporting it as a higher-level interface Ensuring that their teams communicate with a common language to understand the business and its supporting technology. Taken as a whole, these Work Products define the measures necessary to protect sensitive IRS assets, including taxpayer information. 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. As such, these Work Products are the core of the IRS EA. ArchiMate consists of three components– a language core, which was defined in the version 1.0 of the standard, and some language extensions that appeared later, namely the motivation extension that made possible the specification of motivation models and linked them to enterprise architecture… Infrastructure architecture. These can be enterprise wide or for that matter solely focus on a single line of business. Capacity and performance planning To plan your deployment capacity and … Additional legislative requirements include Federal Acquisition Requirements (FAR) regulations. IRS business processes are associated with the specific Location Types at which they are performed in process / location type matrices. Arrays of management capabilities must be provided in order to achieve a "best-practice" ESM solution for the IRS. It identifies emerging technology trends and their potential applicability to different IRS business functions, enabling different stakeholders to identify potential technology opportunities in support of business needs. In the IRS EA, logical systems are defined across the Enterprise. These performance requirements are primarily based on the performance goals specified in the Process Thread Performance Matrix (provided in the EA’s Performance Architecture section). The Location Model View consists of Location Type Definitions which identify and classify all of the distinct types of locations where the IRS conducts business (directly or indirectly) or where critical functions are performed. Figure 1-8: Examples of EA Components. The Business Architecture comprises the following content areas: Business Services and Processes, including a description of an initial set of Business Services. To demonstrate cross-business process integration. The Target Architecture is available through a Web-based two-layer framework providing access to the major components of the Enterprise Architecture: The Target EA Framework provides pre-established views or perspectives across multiple EA functions as the means to access small content segments based on specific EA topics. 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. Allocation of Security Mechanisms to System Components: Allocates the security mechanisms specified in the Security Requirements model to target logical business systems. 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 Enterprise Technology Blueprint is a living document that is continuously reviewed and updated as appropriate. The ESP focuses on the functionality of standards and approved products. Audience: (1). STM is essential to the successful alignment of individual products, standards, and technologies to the Target Enterprise Architecture. Course Hero is not sponsored or endorsed by any college or university. The Functional Work Products define and mandate what the IRS Enterprise must do. Business Owners - Business Operating Units, Agency Wide Shared Services, Security and IT Operations. The IRS EA discusses Enterprise System Management (ESM) as the basis for designing and deploying a complete systems management capability at the IRS. The field initially began to address two problems: 1. The Enterprise Transition Strategy (ETS) describes the overall IRS vision and strategy, and how existing and proposed investments align to it. achieve dramatic improvements in productivity and quality? This information is critical for integrated portfolio planning and project sequencing. 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. There are three primary uses supported by the ETB. 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. 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 Information Dictionary is located within the Glossary of IRS Business Terminology. 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. Poor business alignment—Organizations were finding it more and more difficult to keep those increasingly expensive IT systems aligned with business need. These definitions establish the enterprise-wide terms, nomenclature, and hierarchical structuring of locations, so that consistent names and meanings are used across the enterprise. Process definitions that provide a robust description of processes and sub-processes, including key activities, data inputs and outputs, and security and privacy considerations. 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. 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. Table 8 enumerates and describes each of the components. Data Strategy: develops a coherent approach that will reduce data redundancy and the large operating costs caused by multiple, replicated or similar data stores. The Enterprise Architecture Requirements initiative include programmatic, security, and privacy requirements. The Business Process Model includes: Process hierarchies in the form of decomposition diagrams that show structure. The bottom line: more cost, less value. 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. To demonstrate alignment and support of the FEA Performance Reference Model. The IRS Technology blueprint is a living document that is continuously reviewed and updated as appropriate. The EA describes the enterprise-level, future-state functional requirements that will support the IRS. IT architecture is used to implement an efficient, flexible, and high quality technology solution for a business problem, and is classified into three different categories: enterprise architecture, solution architecture and system architecture. The focus is on functional and physical locations that are durable over time. This tutorial describes how usages of Software Components are packaged and deployed into Application Deployments in Essential Architecture Manager. Authors call it enterprise … (1) All of the existing content, last updated in 2009, has been revised and replaced. This section also contains summaries of organization-level concepts of operations (ConOps) that have been completed, processed, and approved for inclusion in the EA. 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. A relational database hosting Appian internal data and metadata, plus any additional relational databases hosting Appian business data. This hierarchical organization parallels the Enterprise Conceptual Data Model’s definitions of taxpayer and third party. Security & Privacy: manages the integration of the multiple legislative, regulatory, and departmental requirements specified by federal law, such as the Privacy Act, Presidential Directives, and the E-Government Act, including the Federal Information Security Management Act (FISMA). 2.3.2 Components The concept of the components are defined as changeable goals, resources, processes and standards. However due to the high-level nature of the EA, this discussion is limited to identification of the information exchanged on each system interface. 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. 3 Different Examples of University Enterprise Architecture Principles. 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 IRS EA provides the blueprint for modernizing the IRS. Ensuring that their work is integrated with other projects and within the operating units. Information architecture: identifies where and … The external entities are organized hierarchically with top-level entities broken down into second-level and sometimes third-level entities. (For a list of other models of the security architecture view, see the Security Requirements Section). Allocation of Security Mechanisms to System Components (part of the Security Architecture work product). Application architecture. Security Processing Thread (part of the Security Architecture work product). The Business Work Products also define the overall direction for the business systems. Enterprise Operations: provides efficient, cost effective, secure, and highly reliable computing services for all IRS business entities and taxpayers. They provide the basis for defining architectural strategies and implementing complex IT options. Section 508 compliance is a driver for the design of interfaces for all IRS systems. A logical data model is a complete account of the data required by an organization or business area. The following list includes all the Security, Section 508, and Privacy Work Products: Federal Laws and Regulations Applicable to Security, Section 508, and Privacy, Security Considerations of Target Architecture Business Processes, Section 508 Considerations of Target Architecture Business Processes, Security Categories of ETA Business Processes, Sensitivity Classification of ECDM Data Classes, Traceability of Privacy and Technical Security Requirements to Business Process Security and Privacy Considerations, Crosswalk of NIST SP 800-53 and ETA Security Requirements, Allocation of Security Mechanisms to Systems Components. The Organization Model View consists of the following: Organization Descriptions identifies and describes the organizational entities that comprise the IRS. Business drivers defined in the business architecture lead to the elaboration of functional and technical requirements. By sharing these examples I hope … Security Risk Assessment: Estimates the relative degree of security risk associated with major target system components. Enterprise Transition Architecture and its sub-components including Enterprise Transition Strategy, Release Architecture and Enterprise-wide Sequencing Plan. Employing a set of comprehensive sources of guidance including the Enterprise Lifecycle (ELC) Methodology, the ConOps Guidance Toolkit, and the supplementary materials available on the IRS EA website. For example, a business is a taxpayer when it pays its income tax, and a business is an employer when that business withholds taxes from its employees and submits tax-related W-2 information to the IRS. Without enforcement of the EA, the IRS risks buying software and building systems that are duplicative, incompatible, and unnecessarily costly to maintain and integrate. removal of unsupported products), and to minimize overlapping functionality. 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. The Location Types definitions do not try to define organizational locations, which tend to change over time. A security processing thread presented in Security Processing Thread emphasizes the involvement of infrastructure components as an employee logs on to an IRS workstation and begins working on a filing and payment compliance case. To demonstrate alignment of major IT investments with the FEA Service Component Reference Model (SRM). Filing and Payment Compliance: includes collecting delinquent tax obligations and securing delinquent tax returns. The IRS EA describes processing threads that are used to demonstrate how system software applications are involved in executing high-level business processes. The software components described above are of no use without people to author the data, maintain the services, and use the services. Selecting applications software to support business process and service design.s. ERP … An organization’s ConOps is typically a key driver of changes to any of the six domains of change – organization, location, business process, data, applications and/or technology. It is intended as a full planning and implementation lifecycle for use at all levels of scope defined in the Common Approach to Federal Enterprise Architecture: International, National, Federal, Sector, Agency, … Consolidating or standardizing similar processes and services – as appropriate. 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.
