TOGAF 9 Enterprise Continuum

  1. 1. Summarised - 2010
  2. 2. The Architecture Continuum illustrates how architectures are developed and evolved across a continuum ranging from Foundation Architectures, through Common Systems Architectures, and Industry Architectures, and to an enterprise’s own Organization-Specific Architectures.
  3. 3. A Foundation Architecture is an architecture of building blocks and corresponding standards that supports all the Common Systems Architectures and, therefore, the complete enterprise operating environment.
  4. 4. Common Systems Architectures guide the selection and integration of specific services from the Foundation Architecture to create an architecture useful for building common (i.e., highly reusable) solutions across a wide number of relevant domains. Examples of Common Systems Architectures include: a security architecture, a management architecture, a network architecture, an operations architecture, etc. Each is incomplete in terms of overall system functionality, but is complete in terms of a particular problem domain (security, manageability, networking, operations, etc.), so that solutions implementing the architecture constitute re-usable building blocks for the
  5. 5. Industry Architectures guide the integration of common systems components with industry specific components, and guide the creation of industry solutions for targeted customer problems within a particular industry. A typical example of an industry-specific component is a data model representing the business functions and processes specific to a particular vertical industry
  6. 6. Organization-Specific Architectures are the most relevant to the IT customer community, since they describe and guide the final deployment of solution components for a particular enterprise or extended network of connected enterprises. There may be a variety of Organization-Specific Architectures that are needed to effectively cover the organization’s requirements by defining the architectures in increasing levels of detail. Alter natively, this might result in several more detailed Organization-Specific Architectures for specific entities within the global enterprise.
  7. 7. A Common Systems Solution is an An Organization-Specific Solution is an implementation of a Common Systems implementation of the Organization- Architecture comprised of a set of Specific Architecture that provides the products and services, which may be required business functions.

  8. 8.  The TOGAF ADM describes the process of developing an enterprise-specific architecture and an enterprise-specific solution(s) which conform to that architecture by adopting and adapting (where appropriate) generic architectures and solutions (left to right in the continuum classification). In a similar fashion, specific architectures and solutions that prove to be credible and effective will be generalized for re-use (right to left in the continuum classification).  TOGAF itself provides two reference models for consideration for use in developing an organization’s architecture: 1. The TOGAF Foundation Architecture, which comprises a TRM of generic services and functions that provides a firm foundation on which more specific architectures and architectural components can be built. 2. The Integrated Information Infrastructure Reference Model (III-RM), which is based on the TOGAF Foundation Architecture, and is specifically designed to help the realization of architectures that enable and support the vision of Boundary less Information Flow.
