TOGAF 9 Enterprise Continuum
9 likes5,881 views
The document describes the Architecture Continuum which illustrates how architectures are developed and evolved across different levels ranging from Foundation Architectures to Organization-Specific Architectures. A Foundation Architecture provides common building blocks and standards, while Common Systems Architectures guide integration of specific services for common solutions. Industry Architectures then guide integration of common and industry-specific components for industry solutions. Organization-Specific Architectures most relevant to customers by describing final deployment of components for a particular enterprise.
TOGAF 9 Enterprise Continuum
- 3. 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.
- 4. 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.
- 5. 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
- 6. 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
- 7. 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.

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.

- 9. 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.
