Additional Example of Measurement Systems Analysis
Just to be sure, you decide to look at the Bias Comparison chart, which indicates whether an operator is
measuring parts too high or too low. From the red triangle menu next to Measurement Systems Analysis,
select Bias Comparison.
Figure 8.10 Bias Comparison
Looking at the Bias Comparison chart, you make the following observations:
• Operator A and Operator B have detectable measurement bias, as they are significantly different from
the overall average.
• Operator A is significantly biased low.
• Operator B is significantly biased high.
• Operator C is not significantly different from the overall average.
Classify Your Measurement System
Examine the EMP Results report to classify your measurement system and look for opportunities for
improvement. From the red triangle menu next to Measurement Systems Analysis, select EMP Results.
