OK,
Like I said I wear alot of hats here and I do all our QC work as well. I have a new project for which I have to do some SPC paperwork on. You know, bs CPK over 1.33, blah blah. I have been trying out various versions of QC software that does this for a couple years and not found one I really like. Now keep in mind that I am NOT a formally trained QC professional so common sense language works best. So, what program do you use? Or what would you recommend for me?
I have used some of the Excel based programs, and to be honest they seem to assume too much of my knowledge in the area (they are too raw and not neophyte friendly if you will). All I usually need to do is enter my data and print a pretty chart for QC eye wash
It's almost always the same, 30 piece sample, characteristic is length, upper and lower limits. I just want to be able to say "hey I'm doing a 30 piece sample here, here's the info and sample measurements, what's the CPK of the process?". Am I asking too much? Last program I used gave me a crazy CPK of 21.XXX when I know it should have been 1.XXX. Am I unaware of different scales or standards? In other words, is there an Fahrenheit and a Celsius in the CPK world?
Is there a good program out there for an infrequent user like myself? Money isn't really an issue if it fits my bill. Thanks
