Suppose a corporate Rip Van Winkle who fell asleep on the job a generation ago were to wake up today. He would find his company changed almost beyond recognition. As he wandered through manufacturing, he would rub his eyes at the sight of strange new machines. “Something’s very different,” he would mutter. “The shop floor looks like a laboratory.
