Would a customer sign off on an instruction be an acceptable method of allowance for visual criteria? The customer does not want to issue a deviation nor a print change but is OK with the visual criteria. We have the understanding that an email is not a contract therefore it is not acceptable so we have pushed for deviations and print updates.
Also, if the visual criteria is submitted with PPAP would this be enough?
