Toward a Theory of IOIS Variance
Observing that existing models of inter-organisational information systems (IOIS) have not been developed to explain IOIS variance, in this paper the authors develop three criteria a new theoretical framework should meet: 1) It should support identification of and distinction between essential properties of IOIS; 2) it should explain the resilience of IOIS, that is, why (properties of) IOIS persist in the face of environmental change; and 3) it should offer a way of describing IOIS on organisational and collective levels, that is, the level of various types of collectives of organisations, such as networks, associations or industries. This paper then assesses four theories commonly used in IOIS studies (Transaction Cost Theory, Resource Dependence Theory, Neo-Institutionalism, and Structuration Theory) in view of these three criteria. Based on this discussion, the authors develop a new framework for studying IOIS variance which views IOIS as constellations of aligned practices.
