Common Business Services: includes capabilities that are applicable across business domains and systems, such as case management, workflow management, and document and image management. EA Guidance documents include Enterprise Data Standards and Guidelines (EDSG), Service-Oriented Architecture (SOA) Guidance, .NET Guidance, and Design patterns. A Business Service is a complete business transaction or interaction that the IRS conducts with a customer, partner, or stakeholder. 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. In addition, EA manages performance, functional, and system management requirements and provides traceability of data and functional requirements to business processes. This section includes the scope, purpose, and objectives of Enterprise Architecture. 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 Enterprise Architecture Requirements initiative include programmatic, security, and privacy requirements. 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 defines several key concepts, in order to provide a better understanding of how and where custodial financial controls fit into the EA. Enterprise … Nancy Seiger 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.
