Likewise, when I used to write procedure manuals and system documentation, Track Changes with red text and change bars for new content was used to ensure the updates were easily noticed. Immediately an update was issued, the existing set was archived, and all changes accepted in the working copy, so users could see any new changes for the next round. Prior to me instituting that approach, such manuals were often a dog's breakfast of out-dated pages, half-empty pages (because deletions/additions rarely fitted neatly into the same space) and bundles of updates that had never been inserted into the users' working copies. Reprinting entire Sections of the manual was soon recognised as a far more reliable way of getting updated procedures implemented - something that is essential in mission-critical systems.
