Electronic commerce (e-commerce) can occur between a business and its custo
mers, as well as between a business and its suppliers. To facilitate intero
rganizational e-commerce it is often necessary to share supply and demand i
nformation between supply chain partners. Based on our analysis of supply c
hains in several industries we identify the mechanisms (business processes)
required for effective supply chain management. We also identify the infor
mation system components needed to support these mechanisms, show how the i
ndividual components can be integrated into an information infrastructure f
ramework and identify some technologies currently available that can fit wi
thin our proposed infrastructure. We illustrate the usefulness of our frame
work by simulating convergent assembly (commonly associated with motor vehi
cle and aerospace production) supply chain performance under various inform
ation-sharing strategies supported by our proposed infrastructure. We find
that inventory costs can be reduced while maintaining acceptable order fulf
ilment cycle times. This is true because information, which provides the ba
sis for enhanced coordination and reduced uncertainty, can substitute for i
nventory.
