A Social Ontology for Information System Development

Organizations are changing at an ever-faster pace, as they try to keep up with globalization and the information revolution. Unfortunately, information systems technologies do not support system evolution well, making information systems a roadblock to organizational change. We propose to view information systems as social structures and define methodologies which develop and evolve seamlessly an information system within its operational environment. To this end, this paper proposes an ontology for information systems that is inspired by social and organizational structures. The ontology adopts components of the i* organizational modeling framework, which is founded on the notions of actor, goal and social dependency. Social patterns, drawn from research on cooperative and distributed architectures, offer a more macroscopic level of social structure description. Finally, the proposed ontology includes organizational styles inspired from organization theory. These are used not only to model the overall organizational context of an information system, but also its architecture. Social patterns and organizational styles are defined in terms of configurations of i* concepts. The research has been conducted in the context of the Tropos project.
