The design of an Enterprise Architecture (EA) management function for an enterprise is no easy to accomplish task. Various frameworks exist as well as EA management tools, which promise to deliver guidance for performing EA management. Nevertheless, the approaches presented by them stay either on a level too abstract to provide realization support or are far too generic, neglecting enterprise-specific EA related concerns. In this article, we discuss the architecture framework of The Open Group (TOGAF) and detail on its promising but nevertheless highly generic architecture development method (ADM). This article shows how the generic development steps can be complemented by a pattern based approach to EA management providing guidance for addressing specific EA related concerns with step-by-step methodologies as well as with corresponding viewpoints and information models.
