It's appropriate that Volkswagen is scrapping the Inaki Lopez purchasing system as the 1990s wind down. Lopezism's time has come and, mercifully, gone.
Lopez was unscrupulous. Still, his purchasing system at General Motors and VW smashed the old-boy networks that kept the supply chain inefficient for generations. Partly because of Lopez, cars are more affordable today. But the mistrust and excesses of Lopez's policies prompted suppliers not to give his companies their best new technology.
VW is now following DaimlerChrysler in working cooperatively with suppliers. Others should, too.
