I'm not sure on the rule front. The other thing I would point out, though, is that since the 2005 budget, the additional reporting is now done by departments. The biggest addition is around the quarterly financial reports, which didn't exist back then.
My own suggestion is that if departments can take advantage of existing reporting mechanisms once they've gone through the process of notifying unions, employees, etc., to share information.... From my perspective, it's better to use existing tools than to do ad hoc reports. It's just easier to manage.
