Enterprise Architecture Erosion: A Definition and Research Framework Emergent Research Forum (ERF)

Erosion is widely studied in software architecture referring to the gap between what is planned and what is implemented. However, it is not clear what the term means in Enterprise Architecture (EA), a field that deals with the inseparability of applications, business actors, processes, strategy, motivation, and physical infrastructure. This paper defines EA Erosion as a phenomenon of unplanned, emergent, and sometimes unstoppable change in the elements and interactions pertaining to the architecture, with impact in a service region of interest. A research framework is proposed to guide the identification of the regions of interest for erosion factors, impacts, and response actions. Our emergent research shifts the focus from EA representation gaps to the development of EA erosion management capabilities.
