Another Team: How do we do this thing? What aws role do we need?

Me: You do it like this, and I don't know the role by this guy does and all you have to do is ask him for the name of the role to assume.

AT: Ok, great.

AT: We're going to do it like this (wrong way, completely against best practices and completely against what the company architects dictate)

Me: No... thats the wrong way. Don't do it that way. That is bad, because (Reasons A, B, C). Do it the way I told you it should be done.

AT: Ok! I see thank you!

AT schedules a meeting to go over options to do the thing ... including the WRONG WAY and they still haven't talked to That Guy to get the role name they need.
