ABSTRACT
A growing percentage of enterprises around the world are implementing technologies and systems to support exchanges with suppliers. Through public and private networks, enterprises worldwide, particularly large enterprises, are increasingly connected to their suppliers. However, the role played by information systems and technologies in the context of exchanges with suppliers is not well known. Information technology (IT) has been presented as both a means for diminishing the importance of relationships with suppliers and as a means of enabling new forms of collaboration. We believe this apparent contradiction can be resolved by focusing on the impact of shared IT on firms' two key objectives: efficiency and learning. We hypothesize that shared IT increases both efficiency and learning, but through different mechanisms and under different conditions.
