Describe what might be done to improve the measurement and improvement strategy for a company that has an alloy sheet manufacturing process with three material reduction stages: hot rolling, grinding, pickling. The company currently only inspects for thickness of alloy sheets after pickling. They take 45 readings per sheet. They currently do not take readings in the same locations. If one reading fails, the entire sheet is reworked. They are wondering what type of data collection makes sense for their process. They picked a sample of 45 per sheet because somebody calculated it as statistically significant for their process.
