I'm working on a project which requires wireframing in an Agile environment (2-week sprints). My wireframes and storyboards contain features for immediate release as well planning as for future releases.
I'm using Visio, and at the moment have seperate visio files for different functionalities (parts of the site). And each visio file includes wireframes for the different releases. But it means that it's not obvious upfront which releases a wireframe caters for. This works so far, as I can update the pages easily as I go along. But when things change in an early release, it can be a bit of a pain as those changes sometimes need to be replicated to pages for the future releases as well.
I'm not convinced my approach is the best and I'm sure many of you have experience in such environments. How do you currently manage your wireframes and storyboards to cope?
