Why Do Projects Fail to Scale?

When I used to be chief economist at Uber, I would always tell people that I'm going to be the person who stands outside of Travis Kalinik's database. The founder and back then the CEO of Uber in any idea you have has to come through my team before it's going to get on Travis's desk. In a firm or in an organization, the incentives are also set up for confirmation bias. Another consideration is whether you have the same inputs at scale that you used in the Petri dish.
