I’ve heard that (sensibly enough) many big rich companies highly dependent on Microsoft Word use document management systems not wholly unlike version control systems to track the development of their documents over time. Law firms are a good example of places where this sort of software lives. However, many of these systems merely provide and track spaces that store different versions of documents and then associate these versions over time and provide an interface to help Word compare them.
On many of these systems, you can check out an old version of the document and, if you’re not careful, actually change or overwrite the old version basically rewriting or destroying history!
This really sounds more like a version out-of-control system to me.
Imagine how jealous these folks would be if they knew what they were missing. Of course, it’s worth remembering that there are many ways that one can be out of control and there’s hardly consensus on which are most enjoyable or most useful.
