Three years ago, I accompanied a coal mining procurement team on a tour of two excavator manufacturing plants. The first factory had a shiny floor, brand new equipment, and a red carpet on the tour path; the second factory had grease stains on the floor, the equipment looked used, and the workers were hammering on the jigs and fixtures. Coal mine...
