This Continuum begins with foundational definitions like reference models, core strategies, and basic building blocks. From there it spans to Industry Architectures and all the way to an organization's specific architecture.

Comprises two complementary concepts: the Architecture Continuum and the Solutions Continuum. Together these are a range of definitions with increasing specificity, from foundational definitions and agreed enterprise strategies all the way to architectures and implementations in specific organizations. Such coexistence of abstraction and concreteness in an enterprise can be a real source of confusion. The Enterprise Continuum also doubles as a powerful tool to turn confusion and resulting conflicts into progress.
