In recent years, managers have recognized how manufacturing capabilities contribute to a company’s overall strategic strength. The ability to respond quickly to customers’ orders, to customize products to match customers’ exact requirements, or to ramp up production rapidly can be a powerful and difficult-to-imitate competitive weapon. But many corporate managers identify their plants’ capabilities only by accident—as a result of chance conversations with plant managers or operations specialists. Consequently, many managers do not have the information necessary to cultivate, shape, and exploit their company’s manufacturing capabilities. As plants develop, however, they need guidance to build capabilities that meet current and future needs. Plant tours can be a powerful way of providing factories with that kind of direction.
