The capability metrics only display if you specify either an upper or lower specification limit (or both) for the forecast. You can also specify an optional target.
To specify these limits:
Either define a new forecast or select an existing forecast and choose Define, then Define Forecast.
The Define Forecast dialog opens. With process capability features activated, it includes Name, Units, LSL, USL, and Target fields.
Enter specification limits and target values for this forecast into the appropriate fields.
LSL = lower specification limit, USL = upper specification limit, and Target = target value for this forecast. If you prefer, you can enter cell references by typing or browsing.
All of these fields are optional, but Crystal Ball only calculates capability metrics if a value is entered for one or both of the specification limits.
To set forecast preferences at the same time, click the More button,
, beside the Name field.
