Hi all agile masters
Quick question; what is the approach recommended when you realise during a sprint that the original estimation for a user story is too low, its now more complex than what was originally thought, lots of purple stickies start appearing (unplanned tasks). I ask the question to the team " how many points did we burn yesterday" and the developers thinking cause they killed a few unplanned tasks ask back " what happens to the velocity if its now more complex than what it was and can't we burn unplanned points"
And me as scrum master thinking about his burn down charts and planning says "no you can't do that" smiling nervously as he does not really know the answer.
Happened to any of you, how did you handle it.
