A number of architecture frameworks exist, each of which has its particular advantages and disadvantages, and relevance, for enterprise architecture. Several are discussed in Other Architectures and Frameworks .
However, there is no accepted industry standard method for developing an enterprise architecture. The Open Group goal with TOGAF is to work towards making the TOGAF ADM just such an industry standard method, which can be used for developing the products associated with any recognized enterprise framework that the architect feels is appropriate for a particular architecture. The Open Group vision for TOGAF is as a vehicle and repository for practical, experience-based information on how to go about the process of enterprise architecture, providing a generic method with which specific sets of deliverables, specific reference models, and other relevant architectural assets can be integrated.
To illustrate the concept, this section provides a mapping of the various phases of the TOGAF ADM to the cells of the well-known Zachman Framework.
