Scrum accelerates any effort. Yesterday at Agile DC 2013 a group of people who didn't know each other, most of whom probably have never changed the oil in their car and have likely never thought they could do it built a car in three thirty-minute Sprints. And they had a blast doing it.
This is not an anomaly. Anyone can do this. People at Lockheed Martin and Tait Communications have done this too. So can you. There is no greater illustration of the power of Scrum than watching elegant engineering being shaped by eager hands and open minds working together.
And, hey, if you want to build together, let us know.
