who should be the person autholizing-release of product for delivery to customer as mention in (ISO 9001:2008 & ISO 13485;2003) clause 8.2.4.
and what he should or shall do to release the product ( I beleve not only sign the delivery document...)
I can't speak for 13485, but in 9001, it requires you to:
have records that indicate the person(s) authorizing release of product for delivery to the customer' 4.2.4
That means at least one record that shows
at least one specific role/person (and who that was) decided that product X (or batch X of product) was OK to go.
Bottom line: before it leaves
you who produced it and are selling it, you should have a way of demonstrating (here, to an external party) that it met all the requirements.
Who decides that? And what kind of record/s are needed? You get to determine that. But whoever it is should have the authority to decide it and be competent to make that decision, and have some kind of criteria on which that decision is made (as opposed to 'gut feel').
I mean, you could have the truck driver authorising release, but you'd have trouble convincing me (let alone anyone else) that a truck driver had the necessary competency (per 6.2 of ISO 9001) to distinguish between product that
was OK to go and product that wasn't.
Some ways of achieving this (for example) might be to have inspection points along the way, with a signoff /acceptance of satisfactory pass on the final inspection being the record of release.
Signing a 'delivery docket'
might be OK, but only if there were sound inspection processes that ensured that before it got to the delivery stage it had been inspected by someone competent and = OK.
But if it's simply a matter of something being moved across to despatch (without anyone checking final) and then the warehousing person or whoever sending it out... then that sounds a bit loose, to put it mildly, and not likely to meet the requirements.
Hope this helps.
