Smaller teams are a natural way for humans to work. Real day-to-day work occurs in networks – people spend twice as much time with people near their desk than those just 50m away. Some of the most successful engineering companies of our times, including Spotify and Facebook, are built around small teams focused on problems that are important to the customer. These teams are cross functional and organised around what the customer values. They have colleagues from all disciplines that they need within them so that they are empowered to act not wait for another department to sign something off. This structure is more nimble and able to pivot – like a flotilla of smaller ships rather than huge tanker.
