In some studies supplier integratio

In some studies supplier integration is modeled as a construct separate from customer integration or internal integration (e.g., Scannell et al. 2000; Petersen et al. 2005; Swink, Narasimhan and Wang 2007), whereas in others it is subsumed into other integration constructs (e.g., encompassing internal and supplier integration; Maloni and Benton 2000; Vickery, Jayaram, Droge and Calantone 2003; Droge, Jayaram and Vickery 2004; Sanders and Premus 2005;
Aryee, Naim and Lalwani 2008).
