Scaling Up Pushing Scrum out of its Comfort Zone

Single team implementations are where Scrum is most comfortable. Having successfully adopted Scrum for single teams within our department we were now faced with the choice of dropping the use of Scrum on a large multi-team project or scaling Scrum up. We chose the latter, despite the fact that neither we nor anyone else seemed to know exactly what was involved. This is the story of how we dragged Scrum kicking and screaming out of its (and our) comfort zone.
