My company is currently evaluating tools that support the full lifecycle and provide traceability throughout:
- requirements management
- test management (manual for now but we may automate later)
- defects

We are evaluating TestDirector, but the requirements module does not seem as strong as Rational.
We're also evaluating Rational ReqPro, TestManager, Manual Tester (that came out in November), and ClearQuest.

Sorry for the long post, but does anybody have any opinions and can compare the two vendors?

Any comments are greatly appreciated! Thanks!
