The way we have our story cards setup in Jira/Greenhopper is to have a Story Card, with 3 sub-tasks: one for UX, one for Dev and one for Test. This allows us to estimate at the sub-task level, but wrap them up together at the feature/story card level.
As part of this breakdown, our UX story cards are worked on 1 sprint prior to the development and test sprints.
Is it possible to use the Rapid board, to put these UX sub-tasks in say Sprint 5, but have the Dev/Test and Story Card in Sprint 6?
