A method is disclosed for automatically identifying and resolving one or more discrepancies in an outsourced manufacturing supply chain in which a plurality of supply chain partners participate. According to this aspect, information representing one or more supply chain events is received from each of the supply chain partners in a database with which each of the supply chain partners may communicate over a public network. One or more rules are applied periodically to the supply chain event information, resulting in generating one or more alerts pertaining to one or more discrepancies that are found in the supply chain event information. The alerts are communicated to the supply chain partners who are participating in a transaction to which the discrepancies relate. Each alert remains active until second information is received that represents a second supply chain event that resolves the alert. According to one feature, the alerts are periodically escalated until they are resolved. A hub-and-spoke supply chain management system that facilitates the foregoing method, and other features, is also disclosed. In other aspects, the invention encompasses a computer apparatus, a computer readable medium, and a carrier wave configured to carry out the foregoing steps.
