Chris SeiderParticipant@cseiderInclude @cseider in your post and this person will
be notified via email.I can’t imagine doing SPC on amount in and amount out if you are looking at quality as your pain point. Knowing nothing else of your process, why not look at quality % with a run chart. If you’re going to do SPC, I bet you’d have too many things to investigate if quality goes out of control.
