Amazon's 2 pizza team rule

Jeff Bezos instituted a rule: every internal team should be small enough that it can be fed with two pizzas. The goal wasn’t to cut down on the catering bill. It was, like almost everything Amazon does, focused on two aims: efficiency and scalability. 
Efficiency: A smaller team spends less time managing timetables and keeping people up to date, and more time doing what needs to be done.

Scalability: The fact is, larger team size makes people overconfident. People have a tendency “to increasingly underestimate task completion time as team size grows,” researchers Bradley Staats, Katherine Milkman, and Craig Fox explain. In one of their experiments, they discovered that when tasked to build the same Lego figure, two-person teams took 36 minutes while four-person teams took 52 minutes to finish — over 44% longer. Yet the larger teams were almost twice as overoptimistic about how long they’d take.
