    Below are a number of definitions for EA (taken from https://www.ariscommunity.com/users/koiv/2009-08-20-10-definitions-enterprise-architecture-which-corresponds-yours):


    1. ANSI/IEEE Std 1471-2000: “The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution.”


    2. Cap Gemini: “Enterprise Architecture is the description and visualization of the structure of a given area of contemplation, its elements and their collaborations and interrelations links vision, strategy and feasibility, focusing on usability durability and effectiveness. Architecture enables construction, defining principles, rules, standards and guidelines, expressing and communicating a vision”


    3. Forrester, Gene Leganza, 2001:  “Enterprise architecture consists of the vision, principles and standards that guide the purchase and deployment of technology within an enterprise”


    4. Gartner Group: “Enterprise architecture (EA) is the process of translating business vision and strategy into effective enterprise change by creating, communicating, and improving the key principles and models that describe the enterprise’s future state and enable its evolution.”


    5. Gartner Group, Philip Allega: “Enterprise architecture is the process that interweaves business and IT together”


    6. Institute for Enterprise Architecture Development: “Enterprise Architecture is about understanding all of the different elements that go to make up the enterprise and how those elements interrelate”


    7.MIT Center for Information Systems Research: “Enterprise Architecture is the organizing logic for key business processes and IT capabilities reflecting the integration and standardization requirements of the firm’s operating model.”


    8.The ArchiMate Foundation: “A coherent  whole of principles, methods, and models that are used in the design and realization of an enterprise’s organizational structure, business processes, information  systems, and infrastructure ”


    9.The Open Group: “By being inclusive with all other management frameworks, EA is a discipline that helps the Enterprise define , develop and exploit the boundaryless information flow (BIF*) capabilities in order to achieve the Enterprise’s Strategic Intent.” *Boundaryless Information Flow is a Trademark of The Open Group


    10.US Federal Enterprise Architecture Framework (FEAF): “Enterprise architecture is a management practice to maximize the contribution of an agency’s resources, IT investments, and system development activities to achieve its performance goals. Architecture describes clear relationships from strategic goals and objectives through investments to measurable performance improvements for the entire enterprise or a portion (or segment) of the enterprise”


    Why do I need an enterprise architecture?


    According to TOGAF "the primary reason for developing an enterprise architecture is to support the business by providing the fundamental technology and process structure for an IT strategy".


    TOGAF goes on to state that a good enterprise architecture enables you to achieve the right balance between IT efficiency and business innovation. It allows individual business units to innovate safely in their pursuit of competitive advantage. At the same time, it assures the needs of the organization for an integrated IT strategy, permitting the closest possible synergy across the extended enterprise.


    Special Message from the SIG


    Thank you for visiting the ASUG EA Communities.




    ASUG Annual Conference helped attendees to connect, inspire, and innovate - with focus on making running SAP simple, a reality. Save time, money, and effort by connecting to your peers, year round for real-world customer experiences, ideas, and other insights.

    In May ASUG co-hosted with SAP its Annual Conference in Orlando which was attended by more than 20,000 of its 100,000 members. The 3-day event was packed with so much of technical information and a recap of the event at local ASUG chapter meetings are helping further the reach of the educational content. The Enterprise Architecture SIG is working with ASUG Chapter leaders across the country to help their Chapter members cut through the fog. Philadelphia, Atlanta and Tennessee chapters have included EA content in their chapter meetings over the last two months.

    In March, at the Philadelphia ASUG Chapter meeting, Tim Nguyen (from the EA SIG) co-hosted a session with Chris Pauxtis from SAP to discuss how new technologies are changing traditional data warehousing/data management architectures. Both technical perspectives as well as business centric perspectives including real world use cases were discussed during this very interactive session at the chapter meeting. A follow-on web cast on the same topic was conducted in April, sponsored by the Enterprise Architecture.

    In June, at both the Atlanta and the Tennessee chapter meetings, attendees got a a recap of the Annual Conference. On June 10th Jim Cusick, VP Digital Enterprise Platform from SAP recapped the major announcements from the annual conference enlightening the attendees with  SAP S/4 HANA Value Assurance model to help accelerate Digital Transformation, the new relationship of SAP with Microsoft to run S/4 HANA on Azure Cloud,  the Apple & SAP partnership to support Native iOS S/4 HANA Apps etc. Jim also reviewed with attendees the S/4 HANA Journey Brochure, the various components of the SAP HANA Cloud Platform and finally wrapping the session up with Hasso Platner's keynote highlights.

    Similar content was shared at the Tennessee Chapter meeting by Lloyd Burke, Solutions VP at SAP on Jun 20th in Memphis. By actively working with Chapter leadership, the EA SIG is enabling architecture related content to be a mainstay at Chapter meetings. More such outreach is being planned for chapters across the country! Reach out to us if you want know more about this opportunity.

    We hope to see you  next year at our Annual Conference.
