https://community.jmp.com/t5/Discussions/SPC-Sampling-Rate-Determination/m-p/908455#M106699 I am trying to determine an appropriate sampling plan for a manufacturing process which has a dimensional in process control (a length). There is a USL and LSL with a target. Cpk and Ppk are both coming in at &gt;2 on a sample size of &gt;2000 units across two mfg. lots. <BR /><BR />We sampled at a rate of ~5%. I’m trying to figure out what the minimum sample rate is to ensure quality (95/95 confidence coverage). How do I determine this in jmp?
