Capability Analysis JMP Add-In

November 2017: note from the author:

This add-in may not work as intended on MacOS.

This add-in is designed to produce an attractive graphical rendition of a process capability study, and to make it easy to perform analyses across multiple columns of data.

  • Convenient navigation is delivered using a "wizard metaphor".
  • Distribution fitting is automatically performed.  You can control the alpha level at which choices are made (including the ability to force  a normal fit).
  • Buttons on the main window allow you to drill-down and view the "native" JMP output via the distribution platform.
  • Specification limits are retrieved from column properties and can also be added / amended manually.
  • Process capability statistics can be summarised across all columns in both tabular and graphical formats.
  • Easily save / export images of your analysis.
  • Interactive dashboard with colour-coded icons for each variable and sliders that allow you to control Cp and Cpk thresholds.  The dashboard is linked to the main window (click on an icon and the main window will update).

Version 3.00 of the add-in introduces a thumbnail previewer.


The thumbnails can be arranged vertically or horizontally.


The vertical arrangement is designed to sit next to the main window whilst the horizontal layout is intended to fill the full screen.


Hover over a thumbnail to view Cp/Cpk indices

As with app-stores, ratings are a useful mechanism for users to voice their requirements and for developers hear what is and what is not useful.  Based on number of viewings this is probably my most popular addin - but is it actually used or useful - with zero ratings and comments I have no idea.

As the release of version 12 of JMP approaches I'll be making a decision as to whether or not I will discontinue supporting this add-in.  Currently I have no reason to continue with it, so please if you are using it and would like to have it maintained for future versions of JMP please let me know.

This is excelent! nice Add-in very useful since simplifies some steps when data is analyzed.

Thanks kely.  It's been a time since I've updated it so if you find any problems or have ideas for improvements please let me know as I'll be looking at issuing an update over the next few months.


How about add-in for JMP standard edition?

It ought to work with standard JMP

Useful tool for process capability, thank you.   I'd like to see it report the Ppk indices as this has quickly become a more functional indices for larger sample sizes over time.



Does this work on JMP 13? 

I have found it to be very useful tool, I think it would be advantage if option is provided to upload specficiations limits.
