Hi,
I've a question about the time you close the Stories.
To have the burn down really reflect the process of the sprint content, the stories have to be closed, otherwise the story-points wont be burned, and the burn-down want go down.
But usually the developer only sets the story to resolved and on sprint end (demo/review) the PO is closing the story when he accepts it - but doing so, will reflect in an inappropriate burn-down.
How do you handle this?
