As part of your Six Sigma analyses, you can use Minitab® to determine the special Process Capability (Cpk) measure, which can be calculated based on the data supplied by PPM. Process capability describes the stability and reproducibility of a process, i.e., the Cpk value specifies how reliably the specified objectives are achieved.
Procedure
You can create such an analysis in Minitab® by selecting Stat/Quality Tools/Capability Analysis/Normal in the main menu.
To provide the Cpk measure for data export from Minitab®, it must be stored in the Minitab® worksheet. To set the analysis parameters, click the Storage button and select the Cpk option in the dialog box that is displayed.
The Cpk measure is added to the data table from PPM.
You can then use the favorite to easily start the Minitab® evaluation again from PPM.
