Chapter 10. Demystifying e-Procurement: ... > Evolution of e-Procurement Models

Evolution of e-Procurement Models

The e-procurement marketplace is still young; however, the new business models required to serve this market are evolving rapidly. Table 10.1 lists the seven basic types of e-procurement trading models in use and shows their key differences. Note that each of the trading exchanges described in Table 10.1 can also be categorized as either a public or a private exchange. Private exchanges can vary widely in size, ranging from a single company automating its procurement function with its suppliers to a large, complex exchange, such as the online auto parts exchange, Covisint, created by GM, Ford, and DaimlerChrysler.

Public exchanges are most often referred to as portals. In these portals, a company or a group of companies list products or services for public consumption. Public exchanges vary in the degree of value they provide, ranging from product catalogs, order processing and approvals, to fulfillment management and customer care.
