Hi, we have situation in our company. We are pretty new in IATF QMS so I hope that someon will answer my question. We make drawing and send it to our supplier. They are also IATF certified and they established communication protocol (similar to feasibility study) where they propose different solutions for dimensions which they are not capable to achieve. My question is: do we have to change drawing according to theirs proposal or is it enough just to enclose communication protocol/ feasibility study to the drawing in our ERP. Thank you in advance.
