When I have a story with subtasks, I need to move the story trough WIP or only your subtasks?
How JIRA works and how this affect the metrics? Today I move just the subtasks and leave the Story in Sprint Backlog (or Backlog). When all subtasks are finished, I close the story, moving to done. Actually, the JIRA move it to me.
