I tend to agree with Amazon leadership here, as they increase the management layer on a company, the team accountability and ownership gets lost. A more horizontal company is able to do more (per capita) and faster.

The tricky part is what to do when you scale, as you can't simply leave teams to their own devices as they will run their separate ways, so you do more and faster but in the wrong direction.

But then again, when you add management layer you start a chain reaction that creates this complex cake that might stop everything from happening.

It is a complex balance.
