A nice thing about engineering is how much power it gives you even if you don't know where the room is, because you're the one building the thing. Over and over you get to interpret the requirements in consequential ways. Even if you don't get to originate them, the constraints and solutions that you find can often reshape and even overrule the requirements. That feedback is the core of the Agile movement.

I've been in the room, and slowly earned the privilege to stay out of it. With only people like me in it any company would fail. To build my own company I'd have to go back to the room and stay there. But it's a nice niche for a certain kind of nerd. And you can drive the direction of the business from the other side of the door more than you might think.
