Northrop Grumman Newport News geared its lean value stream toward meeting customer commitments rather than strictly using it as a means to improve production. The company is constantly measuring its progress on customer contracts by using scorecards that help managers determine how close or how far they are to meeting customer agreements. Through this process, the company has saved on materials, stock time and labor. This includes a 58% materials savings in the torch repair cell, a 61% reduction of touch time in the shipyard and a 5.8-day reduction in dock-to-stock time.
