Hi!
I'm reading Agile Software Development with Scrum book by Ken Schwaber and Mike Beedle and I have a question about canceling a sprint.
The book says ' If the open impediments on the whiteboard get to be length, this may indicate that the larger organization isn't supporting the team. In this case, the Scrum Master may have to cancel the Sprint.This is a very powerful card to play. It should be played only when the Scrum Master is very concerned that the organization's support for the project is so low as to render the team ineffective...'
