It's interesting to fit my own experience into this - one of the biggest projects I worked on was created by this sort of coordination failure that got so big that it threatened millions of dollars in revenue.
It wasn't even that technical of a problem to solve, it was just making sure that everyone was on the same page for everything so that when we executed the solution it wouldn't explode in our faces.
I guess this is why in big tech, you level up in your politics skills much more thatn you do in your technical skills, but in startups you level up the technical skills much more.
