So TMC communicates data on distribution and the total global supply chain by sending data back and forth in a preprogrammed format. For example, TMC would send information concerning production of certain cars to the dealer network in the U.S.; so those dealers would then know when those cars had been produced and were going to be delivered. Or Toyota would send orders to overseas suppliers for parts. So it uses IT to manage both the sales and production of its global system. Global marketing particularly is a primary function of e-mail in addition to global intercommunication and coordination among various units, subsidiaries, and suppliers.
