Jeff Bezos’s firm is good at selling things to shoppers, but that is the tip of its commercial iceberg
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. The former is obvious. 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.
The thing about having lots of small teams is that they all need to be able to work together, and to be able to access the common resources of the company, in order to achieve their larger goals.
