Factors

In the MSA Design Factors section, add factors for your MSA study.

Note: The MSA Design platform requires one factor with a Part role.

Add Factor

Click to add one or more factors. MSA factors are categorical by default.

Remove

Removes the selected factors.

Add N Factors

Adds multiple factors. Enter the number of factors to add and click Add Factor.

Show Levels

Select to show factor levels. When selected, the following options are available.

Name

Specifies a factor name with a menu to add a level.

Values

Specifies the factor levels, which you can click to edit.

Name

Specifies the name of the factor, which you can click to edit.

MSA Role

Specifies the MSA Role of the factor. Click to select from Operator, Part, Gauge, or None. One factor with a Part role is required.

Note: If your factor name matches an MSA role, that role is automatically assigned.

# of Levels

Specifies the number of levels for a factor.

Randomize

Specifies to randomize the factor in the design table.

Number of Replicates

Specifies the number of replicates between 0 and 10 to include in your design. The number of replicates is the number of measurements in addition to an initial measurement. The default is two replicates, which results in three measurements for each run. To specify a single measurement per run, set the number of replicates to zero.

Replicate Runs

Specifies the run order for replicate runs in the experiment.

Completely Randomized

(Available only when Randomize is set to Yes for all factors.) The run order of the complete design is random.

Batch Repeat

The factor combinations are run in batches. Each replicate set makes up a new batch of runs. The order of runs within each batch is randomized. The variance component error term is the combination of the replicate and the batch-to-batch error.

Fast Repeat

Replicates are run sequentially. The variance component error term is the combination of the replicate and the test-retest error.

Note: A Replicates column is included in the final design table. For the completely randomized run option, the Replicates column is hidden.
