Before revision: For some examples, NASA quotes the following progress ratios in experience curves from different industries: Cost Estimating Web Site - Learning Curve Calculator Aerospace: 85% Shipbuilding: 80-85% Complex machine tools for new models: 75–85% Repetitive electronics manufacturing: 90–95% Repetitive machining or punch-press operations: 90–95% Repetitive electrical operations: 75–85% Repetitive welding operations: 90% Raw materials: 93–96% Purchased parts: 85–88% Experience curve discontinuities The experience curve effect can on occasion come to an abrupt stop.
