The impact of inter-organizational information systems-enabled external integration on capabilities of buyer–supplier dyads

Increasingly, firms are adopting two major supply chain management initiatives: to undertake external integration with supply chain partners and to implement inter-organizational information systems (IOSs). However, academic researchers have not adequately investigated effects of these types of initiatives. Using empirical data from 154 buyer–supplier dyads, we examined the direct and indirect effects (through external integration) of IOS usage on capabilities of buyer– supplier dyads. We found that external integration plays a mediating role in the relationship between IOS usage and capabilities of buyer– supplier dyad. This is the first study to investigate the effects of IOS usage and external integration on capabilities of buyer–supplier dyad.
