Can anyone give me a little help regarding this, I am new to all of this. I am redesigning our process flow chart, PFMEA and Control Plan. My question is, should all 3 charts be tied together as far as the steps for when we get the material to making it to shipping to customer? More importantly in the process flow chart we have a feature that is either critical or significant. I think that is a must but want to make sure everything is compliant with AIAG and ISO 9001:2015
