Spec Limits Column Property
When you perform a capability analysis, you can use Column Properties > Spec Limits to save specification limits as a column property. The Spec Limits property applies only to numeric columns.
Some processes have one-sided specifications. Some have no target. You can enter any of these that apply: a lower specification limit, an upper specification limit, or a target value.
Figure 10.10 displays the Spec Limits section of the Column Properties window for OZONE in the sample data table Cities.jmp.

Tip: Saving specification limits as a column property ensures consistency when you repeat an analysis.
