Managing a portfolio of supplier relations in internet-driven electronic market places. A theoretical discussion

Abstract

Corporative buying has changed from simple purchasing to e-sourcing, which means transforming the interaction between companies from transactional to relational relations. The following paper presents the conceptual framework of a supplier-buyer portfolio, when sourcing is done over the Internet. The perspective chosen is Supply Chain Management. Differing between three types of internet-driven electronic market places (private, consortia and independent e-market), different cooperative business relations have to be set up by supply management. © 2003 by Springer Science+Business Media New York.
