[Sigia-l] Best Tool for Requirements Capture and Management

[Tom Donehower]

Thoughts on best tool for requirements capture and management? Looking at
Pivotaltracker.com. Can anyone share their experience with this or any other
tool? General workflow will be something like this:
1. Identify high level user requirements
2. Write user stories/use cases for each requirement
3. Translate into wireframes and func. spec
4. Change everything at last minute;-)

Best,
