It could come down to something as stupid as:
Executive: "we handled [on demand show ABCD] on day one, that was XX million"
Engineering: "live is really different"
Executive: (arguing about why it shouldn't be that different and should not need a lot of new infrastructure)
Engineering: (can't really argue with his boss about this anymore after having repeated the same conversation 3 or 4 times) -- tells the team: we are not getting new servers or time for a new project. We have to just make do with what we have. You guys are brilliant, I know you can do it!"
