Covisint, the automotive industry's planned global trading exchange announced earlier this year, is fast building a solid roster of blue-chip companies eager to use the exchange to complement their own e-Business initiatives. "To date, more than a dozen major automotive suppliers have signed letters indicating their intent to participate in Covisint," said Gregory Mekjian, a member of the Covisint planning team. "By signing letters-of-intent, these suppliers are indicating their acceptance of the concept and expressing their willingness to provide input to the planning process of this groundbreaking business-to-business initiative."
