Note that it can get trickier than it sounds. (Well, I don't know about big tech, but at least for medium and smaller.)

You need to figure out who the "important people" are, and somehow make sure that they understand and buy into the product definition, delivery dates, etc.

Even if they're 3 levels up from you, and you can't normally interface directly with them, try to find a way to double-check that all the "important people" are on the same page.

Organizational dysfunction happens, and you have to succeed despite that possibility.
