i am auditing a supplier and i need some input on whether i should i accept their methodology or not...
basically we deal with product that we can sell as-is or we can process and if processed it can go thru our stringent system and if not ; then the supplier program takes precedence. Here is my findings on their metal detection process
1 . metal detection check is done 30 minutes post-startup and about an hr or so before they finish ( ther is no pattern ) as they check every 3 hrs. ie they do not check if it is working at the end of the shift.
2. they check each test wand 3 times ie they have 9 checks all in all ( 3x FE; 3xN-FE and 3x SS)
3. if a single (or more) check fails they re-do the whole 9 checks and if it passes , they let go and go their merry way... but if not then they put product on hold since last good check..
can you help me critique this process...
