| guys: perform in a way that your supervisor would think you are a qualified qc firstly, always follow the guidlines (both writen or verbal are ok)
 secondly, if something out of the guidelines, try to make a judgement just using your common sense and report to your supervisor for a double check. remember, don't never just ask your boss to give an answer, you come up with a proposal to your question and ask if this would be the right way to do.
