Abstract
This paper explores in a supply chain context the influences that interorganizational relationships have on the use of information and communication technology (ICT). In particular it analyzes the system use of the emergent patterns of supply chain management (SCM) by considering the underlying supported business processes. The research model was created for the study of the ICT usage patterns and has been applied through a detailed qualitative study conducted on the leading software distributor in Italy. The obtained results lead us to the conclusion that ICT usage emerges from the interaction of parties with available technologies.
