GM Tests Covisint LinksGM Tests Covisint Links

General Motors Corp. is communicating with some of its largest suppliers through online auto exchange Covisint, giving a potential boost to the unprofitable marketplace founded by the carmaker and competitors Ford Motor Co. and DaimlerChrysler AG. GM is testing Covisint Fulfillment, which provides real-time monitoring of inventory levels between suppliers and manufacturers, parts-usage history and patterns, demand forecasts, and other information. If successful, the pilot will help prove the viability of the year-old exchange.
