Sure that's the idea. And if something is broken each member has "agency" to fix it to make it work better. In reality it's only the people who have been given clout can fix it. And some members are too inexperienced to know how to anyway. Also you generally can only fix your level, but if you're lucky provide input up to the next level. Often devs can't even do that because management is narrowminded or have no agency to make change. If the rails have gone off two levels above you or higher, no amount of scrum can fix that.
