That is a nice system.
I am wondering, do you handle the different revision updated in different ways?
E.g. if internal or external auditor finds document with version 16.2.4 in production and version 16.2.6 is actual version in your system. Would you consider this a non-conformity?
I used to not correct spelling and grammar mistakes, until I changed the documents. In the printed manual/procedure book I noted and highlighted spelling mistakes found and when updating the document took these in consideration.
Further more, if a mistake was worth enough to correct it, it is worth enough changing the version number.
If you change relevant information in a document, you should change the version. Changes in HACCP team, seems to me as an important change.
BTW I would not name the persons in the team, but name the jobs.
For every change, please take in consideration that version control of documents is to easy verify if everyone has the same document. Especially in areas were printed documents are distributed.
