Purpose
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.
How to Use
- 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).
- Supports the use Z-Score as an alternative to the Percentile method when calculating capability indices for non-normal data (see 'non-normal distribution options' under the red triangle).
- 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. Click on a thumbnail to view in the main window.
