Alliance or alone? how to build interorganizational information systems

This article shows that the builders of interorganizational information systems (IOSs) struggle most with the problem of whether to build them alone or in an alliance mode. It is suggested that the situation should be studied in the light of the transaction costs involved in the application ofthe IOS. The nature of the application to be handled through the IOS should be the main detemrlnant of IOS design. According to the study, as derived from the transaction cost approach, applications with low transaction

costs are suitable for alliance networks whereas those with high transaction costs should be constructed from an organization's own resources. A market-hierarchy/decision-maker model for determining the righi way to participate in IOSs is introduced. There is a visible trend leading to a proportionally greater use of markets. Information technology lowers transaction costs, and more and more products and services become suitable for marketing through IOSs. A case example is dmwn from the Finnish Insurance Industry, where direct writing is the dominant governance structure. The transaction costs in motor vehicle insurance are studied.
