  • @buckeyeGuy92 The book you need is by Grant and Levenworth. the book is Statistical Quality Control ISBN 0-07-024117-1 (Thank you Gary Cone for remebering which book it is). The first half is SPC and the second half is sampling Or at least the 4th edition is. You need to understand OC curves. If you are learning AQL then you need to understand…[Read more]

    I agree that creating a template is one way to help get all operators to take measurements more representative of one another. And, you are correct that setting up a template to ensure the same points are being taken isn’t representative of the current actual process. So, what might you…[Read more]

  • @BuckeyeGuy92 – one problem off the bat is that you aren’t calculating FPY correctly. It should include all steps, including testing and shipping.

    More generally, the question is – how critical is it to obtain precise data? There seems to be sufficient understanding that this is a problem. Is it agreed that it is sufficiently large to…[Read more]
