Business Domain (Top Level Element) Sub domain (assigned to a Business Domain) For each Business Domain a Business Capability Map exists. This map assigns to each sub domain all belonging business capabilities. In general, business capabilities claim to be free of overlap, express abilities organizations require or offer and provided a logical grouping of these services. A business capability answers the question of “what” a service carries out, clearly distinguishing from the analogous question of “how” something is being carried out. All business capabilities, especially when introduced into a reference architecture, must conform to these principles.
