Visual Roadmaps for Managed Enterprise Architecture Evolution

Managing the evolution of the Enterprise Architecture (EA) is a key challenge for modern enterprises. Current approaches to address this challenge focus on EA plans, indicating projected future states of the architecture. Nevertheless, these plans neglect the role of the information technology (IT) project, which actually performs the transformation of the current to a planned EA. In this paper, we account for the importance of IT projects as drivers of EA transformation by providing a viewpoint for roadmapping the development of the EA over time. Complementing, we further introduce a conceptual model, which explicates the information demands for such roadmap plans.
