I just started a project that I'm attempting to make agile. Those outside the development team (and perhaps project management) won't see it as being an agile, but I'm determined to make it as agile as possible. As part of this effort I'm planning on using TargetProcess to plan out the user stories to be completed for each iteration, and to help those working on the project keep track of what's on their plate for each iteration. As the iterations are completed additional user stories will be added to the project back log and based on priority they'll be assigned to future iterations. It's rather strange to estimate things in something other then hours but I'm looking forward to the experience of working through a project in an agile manner by tracking the velocity of the team, and using that to plan out what features we can fit into upcoming iterations.
What tools or utilities do others use to plan out agile projects? What has worked well? What hasn't?
