I don't know anything about 21CFR820 compliance (other than what the
internet has) but will mention this as a possible issue at my meeting this

Re: Revision control

We put SW version on the cover and on the footer of every page. Users
often print or copy single pages from our manuals to use in the field, and
since there may be units in the field with different SW builds, it's
essential for the user to be able to match instruction to unit build.

The doc revision is less important to us, since our doc revisions roll
with the SW builds. There's a revision block inside the front cover that
lists not only the current rev but all revs of the document and which SW
build each rev is/was for.

It seems to me that you have a 21CFR820 compliance problem if you can't
cross-check your document revisions against their associated device

I write Ops manuals for a medical device manufacturer. We use revision

which version of the software the manual relates to. So, when a client
calls our Service department or one of our clinical educators and says
that they need an additional manual, we don't know which manual to send
them because that history is not maintained anywhere in the manual.
