This report presents a framework for business-to-business e-procurement and e-sourcing activities.   The framework comprises of three primary elements - The first component, "electronic channels",   includes the virtual environments that organizations use to procure products and services from   sellers. E-marketplaces, private exchanges, and retail Web sites are the three prominent e-   procurement channels that organizations use to procure products and services. "Primary   procurement processes" form the second component of the framework. Organizations employ   procurement processes to procure through various electronic channels. These processes include   transactional procurement, auctions and RFP processes. The third element of the framework   comprises "secondary e-procurement processes", which include collaboration and contract   negotiation. Organizations use collaboration and contract negotiation during all primary e-   procurement processes. The report discusses the various framework components in detail.
