https://pubs.opengroup.org/architecture/togaf9-doc/arch/chap35.html The Enterprise Continuum provides methods for classifying architecture and solution artifacts, both internal and external to the Architecture Repository, as they evolve from generic Foundation Architectures to Organization-Specific Architectures. 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). At relevant places throughout the TOGAF ADM, there are pointers to useful architecture assets at the relevant level of generality in the continuum classification. These assets can include reference models from The Open Group and industries at large.
