The topic of supply chain integration is still in its
infancy. This study included only first tier suppliers to the
respondent firm. Future research should address the issue
of how deep the integration should go. Information
exchanges and collaborative efforts could extend to
second and third tier suppliers, however we do not know if
those efforts would result in significant differences in
operational performance. Further, the role of manufacturing
process capability remains to be explored. For
example, it is conceivable that manufacturing process
flexibility is another mediating variable for eBusiness
capability. Research could also explore the differences
between SMEs and large firms in the relationships
between eBusiness capabilities and production information
integration. There are many opportunities for future
research in this area.
