If your 3 month plan relies on other teams delivering on commitments, you've coupled your teams success to that other team.

I usually tell people they should try to plan based on what exists. Occasionally it's not possible and two or more teams need to cooperate, but planning 15 teams with lots of interconnections about hypothetical things is too hard and brittle. If you need it, your teams are probably split in the wrong way.

Yes indeed. I always look for ways to decouple things for this reason even if that decoupling creates a bit more work.
