Different methods to create the matrix for collecting MSA data: ? manually not efficient, error prone, hard to randomize ? repeatedly use Minitab patterned data CalcMake Patterned DataSimple Set of Numbers ? use Minitab DOE “Create Factorial Design” ? GRRsetup custom Minitab macro ? Example MSA: ? plan an MSA study for ?3 Operators, 10 Samples per trial, 2 Trials? ? We want to create a Minitab file with the following columns ? Part or Sample, Operator, Trial, Measurement 019 MSA35 Effective Date: 2/2023 Copyright 20232023 Sigma Breakthrough Technologies, Inc. Used with permission. Copyright 2023 Cummins, Inc.
