When you’re heading a collaboration of any kind, the number of people you bring on board can change how effective your team’s output is. Jeff Bezos, the CEO of Amazon, suggests employing the “two pizza rule” to help keep yourself from including too many people.
Rachel Gillett at business blog Fast Company explains that it’s as simple as it sounds. Imagine you’ve ordered two pizzas for glorious consumption. Now how many people could you reasonably feed with those two pizzas? That’s how many people should be involved in your team project. It should be somewhere between five and eight people, which is a pretty safe range when it comes to possible collaboration downfalls.
