A system of managing a supply chain via a computer network that includes a manufacturing enterprise is provided. The system includes a host system, a network link to at least one supply chain entity, and an a-source application executing on the host system. The a-source application processes a bill of material file, which includes verifying demographic information, collecting pricing data and items in external warehouse files, and mapping the items to a commodity. The a-source application also generates and transmits a bid request to a web site. The a-source application further receives marketing data including customer demand for manufacturing enterprise components and receives and analyzes bid responses received from the supply chain entities to determine which components are in demand. The a-source application further generates an award notice based in part on customer demand and availability of components produced internally compared to similar components offered by outside sources. The a-source application further transmits the award notice.
