Service-orientation is a paradigm that can be applied in different contexts such as products, technologies and design principles. Service-oriented architecture is not necessarily bound to the technical aspects of enterprise system. It can be defined by using conceptual models that are independent of any implementation technology. The principles of service-orientation can be successfully used for separation of concerns by breaking down enterprise system into coherent non overlapping subsystems. The service concept has potential to integrate various modelling dimensions into one comprehensive graphical description. The primary goal of service-oriented architecture is to align the business design with the IT innovations in order to make both organisational and technical system parts more effective. Since the concept of service is quite comprehensible in different domains, it can be used for bridging a communication gap between business experts and technical system designers. Service-oriented paradigm opens a totally new way of enterprise engineering by using service components that span across the organisational and technical system boundaries.
