Figure 8.12 Shift Detection Profiler
Change the parameters to see what your chances are of detecting a 3 sigma shift when only one test is
selected. For the Part Mean Shift value, change 2.1701 to 6.51 (2.17 multiplied by 3). Your probability of
detecting a 3 sigma shift goes up to almost 96%.
Next, change the parameters to eliminate bias and see how that affects your chances of detecting warnings.
For the Bias Factors Std Dev value, change 1.1256 to 0. Your probability of detecting warnings goes up to
almost 99%.
Finally, add more tests to see how your probability of detecting warnings changes. In addition to the first
test, select the second, fifth, and sixth tests. Your probability of detecting warnings goes up to nearly 100%.
Examine Measurement Increments
Finally, see how well your measurement increments are working. From the red triangle menu next to
Measurement Systems Analysis, select Effective Resolution.
