Process Screening

DecileElephant9 — Fri, 13 Feb 2026 09:15:38 GMT

Hi, I am using JMP 17.2 for Process Screening, and I have a few questions about how to use the platform correctly:

Do all process variables need to be in separate columns rather than stored in a single column—especially when using a Limits Table?
Is it possible to use different types of control charts within Process Screening, or is the chart type fixed?
If we need to use multiple columns as process variables, does that mean they must all share the same subgrouping variable?

I appreciate any guidance from those familiar with JMP Process Screening. Thanks!

Have you checked the JMP Help for Process Screening? If I remember correctly:

No (you can use stacked data instead of wide even with limits table)
No (assuming you mean different control chart for different processes)
Yes (meaning if you use grouping columns, same columns will be used for all the variable columns)

Thanks for the answers — they were very helpful.
I also found additional examples in the JMP documentation here:
https://origin-www.jmp.com/support/help/en/18.2/#page/jmp/additional-example-of-process-screening.shtml#

By the way, is it possible to apply different control chart types to different variables by using JSL? I'm wondering whether a scripting approach can override the single-chart-type limitation in Process Screening.
