Hi all.
I have been given the task of compiling documentation required for a PPAP submission. One of these documents require me to calculate the Cpk of the process involved. However, only 1 product can be made per every 8 minutes. I could be wrong, but this leads me to believe that my sample size would be 1 (n=1)
From my understanding, I believe I need to take least 2 samples at same time in order to calculate the Cpk (e.g. 5 samples at time 10:30pm).
How would I go about calculating the Cpk for this?
In addition, there are three Specification Limits that need measuring. Does this mean that 3Cpk's are needed?
Cheers
