IDK, I worked like in ~20 enterprises and I didn't really see what you describe.

"Navigating customer requirements" is mostly everyone speculating on customer needs and pushing the part they own, and whoever happens to get closer to the higher management's ear, wins. Then market decides if that's is a good thing or bad thing. If it's good, normally the person who pushed this doesn't even receive credit for it, because either the command chain too long or the stakeholder's memory too short and postfactum everyone pretends they authored good decisions and opposed bad ones.

It might be tiresome and exhausting, like all intense politics, but it's not hard in any technical sense. Most mediocre people can do it and do it.

For something to be hard and complex you need rules and professionals on all levels who understand and follow the rules and driven by meritocracy alone. That's simply never the case.
