- You should treat emergency hotfixes like any other unexpected interruption in a sprint, e.g. someone being off ill. Make the fix, and then continue the sprint as normal. Your velocity will be lower for that sprint, but that's ok as it should disappear when averaged out over the long term. Of course, it may turn out that you typically lose a day of every sprint making 'hot fixes' so your average velocity will drop, but again this is ok, as it will allow for better estimation of milestones.
