Enteprise Architectures The central message here is the notion of "Organizational Anatomy". Drawing on the experiences from using the System Anatomy (see the entry "System Development", an enterprise is modeled as dependent activity domains; from the most basic on to the ones providing services/products to the market and other clients. This implies that the enterprise is modeled as a "fractal" structure, where each domain ultimately is structured from the activity modalities; something that is not found in other enterprise architecture frameworks such as, for example, Zachman. Moreover, this conceptualization departs from the individual in the organization; thus eschewing the problematic modeling of the individual as an system element among other in, for example, VSM (Viable System Model).
