Use Create Gage R&R Study Worksheet to generate a data collection worksheet for your specific gage R&R study. Minitab requires a certain data organization so that your gage analyses are performed correctly.
This example applies to the Measurement System Analysis Module. For more information, go to www.minitab.com/measurement-system-analysis-module.
The default gage R&R worksheet contains rows for 60 runs. This includes 10 parts, 3 operators, and 2 replicates. The default values should be considered minimum values. You can increase the number of parts, operators, and replicates, however, using smaller numbers of parts and operators will hinder your assessment of repeatability and reproducibility.
In this worksheet, RunOrder lists the order in which the measurements should be taken. Parts and Operators list which operator measures which part for each run. Operator A measures part 6 first, then measures part 4. By default, runs are randomized within operators, so Operator A measures all the parts first, Operator B measures them second, and Operator C measures them third. All operators should measure all the parts before they start the second sequence of replicates. Measurement values may be recorded in C4.
The data collection order in your worksheet will be different than the order in this worksheet, because Minitab randomizes the run order. If you want to generate the same order more than one time, set the base of the random number generator.
