Moffett wants to improve its sourcing of strategic materials from its suppliers, enabling sourcing decisions to be made far more quickly, by means of electronic negotiation. They want to obtain goods at a low cost by having suppliers compete against each other in a reverse auction with expressive bidding. Students are asked to design a reverse auction-like electronic negotiation mechanism for use between this company and its suppliers. In the design report, students need to outline and evaluate the different dimensions of the design space of reverse auctions, and finally make a well-reasoned selection recommendation. They will consider dimensions such as: bidding language (which offer formats are supported), buyer's business constraints, negotiation process, pricing rules, and winner determination.
