Enterprise Architecture

(Enterprise) Architecture has emerged as a key discipline in dealing with continuous change/transformation in which models play a key role. In most current modelling languages (e.g. ArchiMate) there is a clear distinction between business concepts and IT concepts. The question that is addressed in this paper is: is that still justified? It is argued that a more symbiotic relationship between human actors and computer actors, performing essential (business) behaviour side by side is the way to long term success. We also briefly touch upon the impact of such change in (modelling) approach on the way we deal with these transformations from a methodological point of view.
