At one end of the enormous campus there's an assembly plant that looks very much like every other GM plant. At the other end are buildings of various shapes and sizes that serve as the headquarters for all of the plant's suppliers. The idea is to eliminate inefficiency, creating a perfectly seamless manufacturing process. It's a staggeringly ambitious goal, but then, it's a staggeringly big business with very little margin for error. When you make a bet in the global automobile business, you are wagering billions of dollars in a marketplace that suffers from an estimated overcapacity of 2 million units.
