My expertise is in designing and building software, not in organizing teams for optimal productivity. The tools and tech that make the most sense for my project will get me to 100% optimization, but if I pay down a 5% optimization cost to bring all teams in my organization 80% to 90%, a manager should be the one making that choice, not me.

Pretending like everyone has the visibility into the org like you do will get you into trouble, and giving that visibility to everyone will harm their ability to focus on their jobs. I'm not a manager for a reason, I don't want to make those choices, but I need someone to.

Also, not everyone gets to work at Google. Advice like this needs to have value at Medium Sized Company, Inc., because those are the people who are most out in the cold. An Apple product manager has every tool on the planet available to him/her to figure out how best to help his/her team, but the guy/gal managing a dev shop in Carson City might not.
