Collaboration in software development

Last night I attended a presentation by Drew Showers (Borland) - the subject of was 'collaboration in software development'. He spent a good deal of time reviewing RUP, UML and the software development process and less time on his company's product CaliberRM. That's good! Drew has a rich software development experience in  (Lockheed-Martin, IBM etc) and his emphasis on requirements management & iterative development hit the right note. The CaliberRM (Requirements Management)demonstration was very interesting - found out that it as an API that can be made to integrate it with Visual SourceSafe!
