I'm revising for a Software Engineering exam and one of the questions got me wondering. It showed a burndown chart where the team had made no progress on user stories for 10 days. The question was "Outline and justify any action that the ScrumMaster may consider taking at this point".
I've thought about drastic action, like stopping the sprint. Then there is to assign pair programming to help users and to consider breaking down user stories even more. Does anybody have any other suggestions? (This question was worth four marks on a past paper).
