Re:Trac/Subversion + Knowledge Tree (Score 1)

I agree with Qbertino. Trac (http://www.edgewall.com/trac/) will allow you to integrate Wiki/Versioning/Tickets/Roadmap/Timeline. This will work best in amongst the software developers, but may not be something the functional analysts will find familiar or easy. Although, I would imagine heavy adoption of this across the whole company would be the best situation for increasing productivity amongst the software developers. If you're looking for something to handle the duties of Sharepoint and Microsoft Word, get Knowledge Tree and consider the professional version w/ Windows and Microsoft Office integration. This won't offer any direct benefits for developing software but will handle document management quite well, including versioning, checkout, etc. Think about how you could use both. This will probably be your best solution.
