Thankfully at this time we have no retention requirements from customers, but we do cover that topic in our procedure! We're mostly automotive but supply to the people supplying the big companies. Now, another quick question about document control, is a document change request form / document change log strictly required for documents that wouldn't really fall under 8.5.6? Having trouble thinking of a quick example off the top of my head, but something that doesn't directly impact production. We track revision level, date, and all that good stuff on the document itself with a link to it on our Master Document List database.Sounds like you are on the right track! Just make sure that your minimum retention times work for your toughest customer contract. We are mostly medical which is why we have the 15 years. Good luck!
