There are three possible reasons for an answer of 'I don't kmow'

1. Something is unknowable 2. The person being question has insufficient expertise to discover the answer 3. The person being questioned hasn't really thought about it.

You appear to be assuming that 1 is always the reason.

There's a lot more than those three possibilities. I don't really believe that anything is unknowable, aside from semantic arguments about Godel's incompleteness and things like that.

What I'm saying is, that at the moment someone asks you "How long will X take to bring through the software development process", "I don't know" has to be a possible answer or your whole method is corrupt.
