Using the Capability red triangle menu, you can add normalized box plots, capability indices, and a summary table, as well as display a capability report for each individual variable in the analysis. These options are described in Capability Platform Options.
You can change the report default preference at File > Preferences > Platforms > Capability. Follow the instructions in Example of the Capability Platform to produce the report shown in Default Results for Semiconductor Capability.jmp.
Default Results for Semiconductor Capability.jmp
The Goal Plot shows, for each variable, the spec-normalized mean shift on the x-axis, and the spec-normalized standard deviation on the y-axis. It is useful for getting a quick, summary view of how the variables are conforming to specification limits. Hold your cursor over each point to view the variable name. The Goal Plot red triangle menu has the following commands:
Goal Plot shows the Goal Plot for the entire data set for the Semiconductor Capability.jmp sample data table after selecting Shade CPK Levels from the Goal Plot red triangle menu.
Mean Shift Normalized to Spec = (Mean(Col[i]) - Target) / (USL[i] - LSL[i])
Standard Deviation Normalized to Spec = Standard Deviation(Col[i])/ (USL[i] - LSL[i])
By default, the CPK slider and number edit box is set to CPK = 1. This approximates a non-conformance rate of 0.0027, if the distribution is centered. The red goal line represents the CPK shown in the edit box. To change the CPK value, move the slider or enter a number in the edit box. Points on the plot represent columns, not rows.
JMP has a preference for plotting PPK instead of CPK. When this is on, the slider is labeled with PPK. You can change the preference at File > Preferences > Platforms > Capability.
The Capability Box Plots show a box plot for each variable selected in the analysis. The values for each column are centered by their target value and scaled by the difference between the specification limits. For each column Yj:
with Tj being the target
Capability Box Plot shows the Capability Box Plot for the Semiconductor Capability.jmp sample data table as described in Example of the Capability Platform. The left and right dotted green lines, drawn at ±0.5, represent the standardized LSLj and USLj respectively. This plot is useful for comparing variables with respect to their specification limits. For example, the majority of points for IVP1 are above its USL, while the majority of its points for IVP2 are less than its target. PNP2 looks to be on target with all data points in the spec limits.
When a spec limit is missing for a column, the box plot is colored. If only the upper spec limit is specified, the box plot is colored blue. If only the lower limit is specified, the box plot is colored red. See Missing Spec Limits. A note at the bottom of the plot describes the calculations used for the plot.
