I inherited a document control system that was developed after the company had already been operating for a while and that didn't include all documents automatically and I'm struggling to convey to certain sections which documents should be controlled. In particular, one department has Quick Reaction Checklists that they claim should not be controlled because they change often. However, in my mind, these are security/crisis documents for which it is doubly important to ensure that everyone is using the same version of that QRC. Input?
