It can be a tax service or a service that provides a tax product. Enterprise Architecture Requirements are required by federal law, IRS enterprise architecture principals, and vision and strategy mandates. 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. Data architecture in the EA covers the following areas: Data modeling, categorization and relevant subject areas. Traceability of Privacy and Technical Security Requirements to Business Process Security & Privacy Considerations. IRS Organization Descriptions, which are part of the IRS EA Organization Model View, identify and describe the organizational entities that comprise the IRS. 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 System Design items provides a high-level description of the design of the systems needed to satisfy the functional, performance, security and privacy, and system management requirements detailed in the System Requirements . The Location Types definitions do not try to define organizational locations, which tend to change over time. Here is our take: Business Architecture components: Strategy Clarification: Business architecture needs to start with understanding the “why” or the strategic rationale of an enterprise. These key concepts are: The enterprise context diagram profiles the business environment in which the IRS operates. The bottom line: more cost, less value. 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. The ESP complies with high-level section 508 requirements. The Enterprise Transition Strategy (ETS) describes the overall IRS vision and strategy, and how existing and proposed investments align to it. Enterprise architecture management (EAM) is a structured approach that an enterprise uses for creating, managing, and using enterprise architecture to align business and IT. It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. In addition to three major framework components discussed above. EA continuously assess the IRS landscape and proactively identifies and validates needed changes. Section 508 compliance is a driver for the design of interfaces for all IRS systems. 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. Enterprise Target Architecture and its sub-components including EA Strategy and Function, EA Roadmap, EA Principles, EA Requirements, Business Architecture, Organization and Location, Data Architecture, Application and Technology which covers System Architecture, System Interfaces, Technical Architecture, Application Architecture, Security Architecture, System Management Architecture, Technical Guidance and Design Patterns, Service Repository and Service Oriented Architecture, and Enterprise Standards Profile. The EA describes the Enterprise-level, future-state functional requirements that will support the modernized IRS. These operational policies and procedures must be well defined and, in most cases, captured in the IRS Systems Standards Profile (SSP). The components … The Enterprise-wide Sequencing Plan describes how the existing and proposed investments align to the IRS vision and strategy. The EA describes the future-state business processes that will support the IRS. 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, … Defines the ERP architecture through the physical components of hardware, software, data and networking. It also is likely that the tools that are deployed may vary from one platform type to another. Only products listed in the ESP, a technical product repository, may be deployed (e.g. The Enterprise Systems Management (ESM) Requirements exist primarily because systems and networks are not currently self-healing. 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. 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. This will lead to expansion and refinement of the performance requirements specified herein, and may result in replacement of some of the requirements based on supplemental sources. 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. Ensuring that their business results are consistent with the business services offered, business process visions, and supporting high level process designs. Coordinating and optimizing key business operations and services across the organization. The RA allows the user to identify the impact of each planned project release on the current IT production environment (CPE) in terms of newly built business applications, data stores, data interfaces, and infrastructure systems as well as project releases that will modify or permit the retirement of existing systems. Ensuring that their business results are consistent with the mission and vision of the Agency. These standards contain technical criteria specific to the usage of technologies. Allocation of Security Mechanisms to System Components: Allocates the security mechanisms specified in the Security Requirements model to target logical business systems. Each release architecture specifies the state of the enterprise after the system deployments planned for a fiscal year. As appropriate, Enterprise Functional Requirements and Data Requirements are allocated to these systems. Inform IT Investment Prioritization and Decision Making: The ETB provides a framework for identifying and evaluating potential investments and ensuring their alignment with a common enterprise vision. EA Analysis and Design Element #3: Current Architecture. 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. If a term does appear in both, the definition in the Glossary of IRS Business Terminology has precedence. The Project Chartering process includes guidance for completing the alignment portion of the Charter, a sample of a completed EA Alignment table, a collection of charter documents, and a link to the Enterprise Life Cycle Process Management Office (ELCPMO) project charter data item description document. The inclusion of all systems components in the management solution is vital to ensure a consistent, cost-effective, and highly available operating environment. 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. Security Risk Assessment: Estimates the relative degree of security risk associated with major target system components. The EA provides business scenarios that demonstrate how selected business processes contained in the EA support key business events. 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. 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. Purpose: An enterprise architecture is a strategic information asset base which defines the mission, the information and technologies necessary to perform the mission and the transitional processes for implementing new technologies in response to the changing needs of the mission. Infrastructure: provides computing and communication systems/networks/platforms supporting IRS people and applications. The intent of the ConOps framework is to: Conceptualize a holistic future state of an organization based on organizational and technological changes. Functions that are organized primarily by the business areas described in Business Processes. ERP … IRS business processes are associated with the specific Location Types at which they are performed in process / location type matrices. It 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. Security Categories of ETA Business Processes: Identifies FIPS 199 security categories for target business processes. reusable set of well-defined functionality that encapsulates its implementation and exporting it as a higher-level interface 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 is useful for this discussion to define three hierarchically related aspects of strategic planning (see Figure 2.2): 1. It is divided into the Glossary defining all terminology and the Acronyms List defines acronyms used in the EA. 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. Arrays of management capabilities must be provided in order to achieve a "best-practice" ESM solution for the IRS. EA describes programmatic requirements as those based on security and privacy; the IRS; and all agencies. These problems, first recognized 20 years ago, have today reached … 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). The ABA represents the IRS' Current Production Environment (CPE) with business applications, external systems, and external trading partners. Security Categories of ETA Business Processes. The software components described above are of no use without people to author the data, maintain the services, and use the services. 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. A logical data model takes the conceptual model down a level of detail to the concerns of technical staff rather than the business users. Information technology (IT) strategic planning 3. A complete solution is likely to be composed of a collection of well-integrated products that each provides a subset of the ESM mechanisms. 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 following list includes all of the work products from the Business Architecture and also includes the Programmatic Requirements. This section also contains summaries of organization-level concepts of operations (ConOps) that have been completed, processed, and approved for inclusion in the EA. 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. These can be enterprise wide or for that matter solely focus on a single line of business. It describes the external entities with which the IRS interacts. The goals of defining these common decisions are to: Ensure that projects deliver functionality that can be integrated and maintained in the IRS environment. TOGAF 9 encompasses the entire enterprise architecture … Filing and Payment Compliance: includes collecting delinquent tax obligations and securing delinquent tax returns. EA Guidance documents include Enterprise Data Standards and Guidelines (EDSG), Service-Oriented Architecture (SOA) Guidance, .NET Guidance, and Design patterns. Cybersecurity or information security strategic planningFIGURE 2.2Strategic Planning Enterprise strategic planning involves defining long-term goals and objectives for an organization (for example, business enterprise, government agency, or nonprofit organization) and the development of plans to achieve thes… Authoritative data definitions and guidelines. The Change Request (CR) process ensures that all projects adhere to the standards and guidelines set forth in the EA. Documents and data about how the IRS conducts business. The field initially began to address two problems: 1. The ELC Domains of Change view of the EA is really a summarization of all the technical components of the EA as they guide the development of systems. 3 thoughts on “Technical Architecture Components” Pingback: Technical Architecture Component – Service Delivery Model « Enterprise Architecture, IT Strategy & Others. 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. The business domains support the effective and secure execution of the core mission business functions. The ESM solution deployed at the IRS must be flexible enough to adapt to a wide variety of operational models. By sharing these examples I hope … The Target Architecture comprises the Business Architecture, the Systems Architecture, Application Architecture, Data Architecture, Security Architecture and the Technical Architecture. Audience: (1). It provides high-level perspectives of the application architecture, the data architecture, and the conceptual technology architecture views. The Functional Work Products define and mandate what the IRS Enterprise must do. 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. 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. Business and IT Planners: support the following planning activities: Assessing all proposed business and technology solutions in the context and framework of the Business Architecture to avoid overlaps and duplication of proposed projects. Like other business enterprises, the IRS offers an array of services, similar to a menu or catalog of services that identifies the various products and services that one can obtain from that business enterprise. The IRS EA provides the blueprint for modernizing the IRS. A relational database hosting Appian internal data and metadata, plus any additional relational databases hosting Appian business data. Internal Management: manages IRS human capital and financial accounting. Finally, Technical Domains were recently introduced into the MV&S Framework. This information is critical for integrated portfolio planning and project sequencing. This model also indicates the FIPS 199 security category of Taxpayer data and Personally Identifiable Information (PII). 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 Online Service Repository captures the list of services and their descriptions contained in the IRS. Twenty years ago, a new field was born that soon came to be known as enterprise architecture. The goal of the approval process is to align to the strategic direction, ensure products are supported (e.g. 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 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. These programmatic requirements have been mandated by higher authorities and exist independently of EA. 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. Sensitivity Classification of ECDM Data Classes (part of the Data Requirements work product). Role Definitions identify, classify and explain the roles that support the core business of the IRS. Provides a high level overview of architecture and components, including Bot Creator, Bot Runner and Enterprise Control Room. Consolidating or standardizing similar processes and services – as appropriate. To demonstrate cross-business process integration. It provides IRS business and IT stakeholders a common long-range view of IRS operations from a business and IT perspective and depicts the alignment between business and IT concepts. It informs, guides, and constrains all IRS IT Projects in how to optimize the interdependencies and interrelationships among business operating divisions and the underlying IT that supports operations. (Sensitivity classification indicates whether a data class is sensitive or non-sensitive and, if sensitive, its sensitivity type [for example, Taxpayer, Employee Personal, Law Enforcement].) 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. Exempt organization (IRC Section 6104) public disclosure of 527, Taxpayer receives individual assistance with unpaid balance for previous year’s taxes. Enterprise Services: sets critical enterprise standards to promote compatibility and common practices across the IRS, applies engineering expertise directly to projects and programs, establishes frameworks for IT demand management and prioritization, and establishes governance and control methodologies for the IT portfolio. 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. Future versions of the Business Architecture are expected to provide more complete specification of performance goals. 3 Different Examples of University Enterprise Architecture Principles. One or more search servers. 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 Enterprise Architecture Requirements initiative include programmatic, security, and privacy requirements. Infrastructure architecture. Process definitions that provide a robust description of processes and sub-processes, including key activities, data inputs and outputs, and security and privacy considerations. Unified Architecture Framework (UAF) -- which is a complex but flexible enterprise architecture … Other models of the security view include: Security Considerations of Target Business Processes: Specifies very high-level security requirements for target business processes. It illustrates how these programs and projects fulfill business goals and objectives for IRS domains, the IRS and Treasury. The Business Work Products define all business-related aspects of the target state including business processes, organization, and location. Business drivers defined in the business architecture lead to the elaboration of functional and technical requirements. The Standards and Technology Standards (STM) organization is responsible for administering the configuration and change-management processes. In general, the IRS EA presents a multi-layer technology architecture. 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. 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.
