MS Word templates … do you use them?

When I say ‘template’, I don’t mean a single-paged document with a few headings that you have to try and craft a report from.  I mean a multi-paged fully-branded document based on a company-wide style sheet.  And I mean a structured document with standard headers, footers, sections, headings, and lots of instructions to explain what’s expected of the author.

So, why bother with templates like that?
