Abstract: A web-based enterprise application system facilitates strategic e-sourcing for both buyers and vendors. The system provides automation capabilities in both strategic partner selection (providing buyers and vendors with the tools necessary to choose the most suitable long-term business partner or partners) and strategic partner management (providing buyers and vendors with tools and content to build and maintain long-term value-added business relationships). For the former, the system provides an RFP management platform that helps buyers to manage the RFI/RFP process from requirement definition to negotiation and a counterpart proposal management platform that helps vendors to respond to requests for information and proposals by providing them with a flexible, accurate and intuitive online framework. For the latter, the system provides a contract management platform which helps buyers and vendors to build and maintain contracts to further long-term value-added business relationships.
