The two-pizza rule and the secret of Amazon's success

In the early days of Amazon, 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. A smaller team spends less time managing timetables and keeping people up to date, and more time doing what needs to be done. But it's the latter that really matters for Amazon.
