I am creating a QMS from scratch and one of the questions I have is when setting up the format for an SOP, does an SOP need to have an approval signature on it? On company letterhead, I have title, document #, revision, effective date and Page X of Y. Do I also need to have it signed off? If so, is that the Quality Management Representative or the author?
On company letterhead I would only add the logo of the organization to your list.
Normally, when I work with organizations, if they keep paper versions of the documentation, I just ask them to sign an original that will be kept as a record. Other paper versions aren’t signed, but they have to match version # and content with the original approved.
I recommend that the signing, on paper or digital, should be done by the person with authority to make the content of the document an internal rule.
