I'm surprised nobody's mentioned DOORS (It's by TeleLogic). It's a requirements matrix system that's extensible, powerful, and reasonably cheap if you're a mid-size (or larger) business...on a side note there's a modified Wiki by a Edgewall called Trac. I've not used it personally but it looks like the right stuff...
