Pl. provide me the examples of how we can calculate the CP & cpk.
MiniTab is probably your best solution, and will also provide a whole wealth of other analytical tools to aid process capability and performance.
It can be done in excel, but is a little cumbersome, seeing that MiniTab will perform the number crunching activity.
Easy to import the data from an excel spreadsheet, and the graphs will export into any MS format (word or power point ) for distribution and presentation.
Dear Denis,
Can U please link a example file.
