I’ve noticed that on some of our Scrum projects we sometimes have a gap of a few days between starting the next Sprint. Often this is because getting time arranged to meet with the customer can’t be done on the day after the Sprint ends necessarily.
I think we’d be better off if we could start the next Sprint right away, but given the fact that the business side of our organization and our PMs haven’t really embraced the idea beyond the official pilot it appears to be something we’ll have to accept. At the end of the day we’re delivering on the Sprints and that’s the critical part.
