• Resumen

  • The assessment of an automated continuous measurement system used for 100% inspection of a high-volume manufacturing process is considered. The proposed plan has two improvements over the standard plan for assessment. First, the value of using the known process characteristics in the analysis is demonstrated. Second, an alternative sampling plan is described where parts with extreme values are deliberately selected from the group of measured parts, and then are remeasured. This plan, called selection leverage, is shown to be more efficient than the standard plan. The planning and implementation of a leveraged assessment study is also discussed.
