To add to that, the roles also need to be identified. When some obscure thing breaks you either need to go on a quest to understand which are all the roles involved in fixing it, or send a much vaguer "let me do X and Y" request to the approval chain and have them figure it out on their end. And as the approval agents aren't the ones fixing the issue, it's a back and forth of "can you do X?" "no, I'm locked at Y" "ok. then how about now ?" Overprovisioning at least some key people is a fatality.
