Enterprise Architecture

What is an Enterprise?
  • A collection of organizations that share a common set of goals, such as a government agency, part of a corporation, or a corporation in its entirety.
  • Large corporations may comprise multiple enterprises.
  • An "extended enterprise" can include partners, suppliers, and customers.
What is Architecture?
  • The organizational structure of a system or component (IEEE Standard 610, Standard Computer Dictionary: A Compilation of IEEE Standard Computer Glossaries)
  • The fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution (IEEE Standard 1471, IEEE Recomended Practice for Architectural Description of Software-Intensive Systems)
In other words, Architecture is:
  1.  A formal description of a system, or a detailed plan of the system at a component level to guide its implementation
  2. The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time
What is Enterprise Architecture?
  • The organizing logic for business processes and IT infrastructure reflecting the integration and standardization requirements of the firm's operating model (MIT Center for Information Systems Research)
  • A conceptual blueprint that defines the structure and operation of an organization. The intent of an enterprise architecture is to determine how an organization can most effectively achieve its current and future objectives (SearchCIO.com)
