The Two Pizza Team Rule

“The value of a communication system grows at approximately the square of the number of users of the system.”

– Metcalfe’s Law

Metcalfe’s Law has a corollary when it comes to project teams:

The efficiency of a team is approximately the inverse of the square of the number of members in the team.

—Marc Hedlund

As a team grows in size, communication breaks down and devolves into group think.

A good rule of thumb on the right team size is instituting a two pizza team rule:

The two pizza team rule: Any team should be small enough that it could be fed with two pizzas.
