Engineering

"A good team is ultimately what makes or breaks the problem. If the team isn´t the right one, they make little mistakes that erode the solution and in the end, you don´t know what mistake you made, but it doesn´t work. You need the control every day, every week. A new person will make little tiny judgment calls and not realize the cumulative effect. So after a few months you have actually destroyed the idea while you made no recognizable mistake. It was a sequence of small things." Urs, key engineer in the development of Google. Actually, "The Key".
