Modifying Complexity/Story Point
For a couple of different reasons we would like to add a 0.5 pts value to Story Points. When I add 0.5 to a Story and save it, the plan remains 0 pts/0pts. If I add 2 0.5 pt stories then the plan still remains 0pts/0pts. Is there any documentation on the proper way to modify Complexity and Story Points to make sure the values all work?
