"(b) nobody gets round to updating the documentation."
That's why I work so hard to get our Parish Council documents to specify outcomes not methods. And that's sometimes a hard task.
Me: Recommend a total number for the borough such that our town is allocated an whole number.
Q: What would that be?
Me: Something between 45 and 49.
Q: So we're going to pick a number between 45 and 49?
Me: No! We're recommending that *they* pick a number which would give our town a neat whole number, which would be between 45 and 49 for the whole borough.
Q: So, we're recommending between 45 and 49?
Me: No! We're recommending that *THEY* pick a number that gives *US* a *WHOLE* number, *NOT* what that number should be.
Q: So what number are we recommending?
ARRRRFGFGGHH!!!!
