Gel instantly
As a team, we knew that we'd be assessed on how we worked together, and the processes we put in place. My focus was getting designers from multiple organizations to gel more or less instantly and under intense pressure without overwhelming them (or myself). This meant a very fast division of labor into teams, with clear assignments, leads, and avenues for support. We started with a kickoff -- and an ice breaker, because how can you be expected to work well with people you don't know at all?
