The problem with big teams isn’t the people, it’s the communication.
"Communication is terrible" -Jeff Bezos
As you add more people to a team, the number of relationships between those people increases exponentially. There is even a mathematical formula for this: n(n-1)/2
But maths can be a little dry, so I made a visualisation. Click the button below to add people to the team and see how the number of links between people grows exponentially as the team scales.
So how big is too big? It’s hard to say. I’ve seen various people throw around numbers anywhere from 5 - 12.
