I think diagrams regardless of which type you use are most useful to make sure everyone is aligned on what those options are _in order to have the discussion_.

I think diagrams regardless of which type you use are most useful to make sure everyone is aligned on what those options are _in order to have the discussion_. Then the discussion can take place and it logically comes to the right outcome (hopefully) as everyone has clarity on what’s being discussed. Without the diagram people talk about different things but think they’re talking about the same thing. You need diagrams. Even if you just write it on white boards.
