In other words, the priority for production during the war was consistency and control, not saving time or increasing profits, though wartime demand and wage controls kept corporate coffers full. An alternative form of automation popular among machinists, “record-playback,” was never seriously pursued, although it was also efficient. Unlike numeric control, the record-playback method was analog, storing the precise movement of a machinist, and so still required a skilled hand. Rather than pursue efficiency, management sought to wrest control of production away from the machinists.
