Jeff Bezos famously enforced the “Two Pizza Rule” at Amazon by requiring that no meeting have more attendees than could be fed with two pizzas.
Pizza is awesome, and so are you. But you get less awesome when you work with a team of 49 other individuals to reach consensus on the future of children’s education over the course of next three days.
That’s why Jeff kept team size small – When you can feed all the decision makers around one table with two pizzas, the communication streams are optimized and ready to get stuff done.
As team size increases, the number of communication links increases at O(n2).
