The Process Capability launch window also contains the following options and specifications:
By
Produces a separate report for each level of the By variable. If more than one By variable is assigned, a separate report is produced for each possible combination of the levels of the By variables.
Specify Alpha Level
Specifies the significance level for confidence limits.
Show Spec Limits Dialog
Specifies how to handle columns that do not have specification limits.
Note: It is good practice to ensure that specification limits for all process variables are specified as Spec Limits column properties or to load specification limits from a Limits Data table. (See Limits Data Table.) Otherwise, you can specify limits interactively in the Spec Limits window that appears after you click OK in the launch window (unless you select No (skip columns with no spec limits) on the launch window).
