A measurement system's analysis tools used here are to assess the precision and accuracy of the measurement system. Commonly, tools such as Gage R&R are used to assess the precision of both the measurement device and the operators to the variation in the process.
The R&R in Gage R&R stands for repeatability and reproducibility. These terms indicate the variation in measurements by the measuring device when performing repeated measures on items and the variation between operators.
Accuracy can be assessed by using Type 1 Gage studies and linearity and bias studies. Typically, they can include calibration studies to ensure that a measurement device is recording the correct values.
Finally, attribute studies can be used to assess the ability of appraisers to make visual inspections.
Gage R&R studies performed on paper or in applications such as Excel can often be held in a very different format to that of the columns in Minitab. To resolve this problem, the crossed...
