Re: Control Of Documents: Controlled Copy - Controlled copy stamp
You need to classify documents as controlled and uncontrolled.
A controlled document can be updated, amended, reviewed and approved prior to issuance and distribution to intended users or copyholders. Uncontrolled document is a copy of document distributed to whomever upon request for specific purpose (training., audit, etc). There are a lot of ways to distinguish controlled and uncontrolled e.g. stamping. If stamping works for you, so be it.
