In case Jane doesn't get back right away, Ron you have pretty much summed it up.
But let us keep in mind that not everything requires a procedure and some procedures are so difficult to use that the auditing isn't simply about following procedure. In addition, procedures don't have to give every little detail.
It is about the process's effectiveness, of which definition plays a part; even if that definition is a clear and consistent description by auditees of what goes on and why, what the outcome is (including records as required, which you would verify), how the auditees can tell if it was good or bad outcome, and what to do if the outcome was not satisfactory.
