On supplier material source inspection, any other relevant criteria other than concentrating on the material (current inspection task)? Lessons learned proved that material inspection only is not enough, as specific nonconformances that was corrected before shipment produced new nonconformance. Where will the best supplier source material inspection occur; is it before, during, or after the production? Thank you fo

I'm sorry what exactly are you look for on this? thanks

I am actively involved in source material inspection and have the opportunity to visit another supplier of manufacturing aerospace industry to do this task very soon. The criteria is primarily inspection in nature on material conformance before it is shipped to our company. Other than this, appreciate feedback on the best practice as addition, if any. Thanks.
