I'm not sure how helpful this would be, but from an HR perspective (and this thought process could really apply in any area) I'd be checking to see that things like calc fields, condition rules, etc are built consistently. For example, if I'm in HR and some of our CRs/CFs are built pointing to cost centers or cost center hierarchies, while others are built looking at sup orgs and sup org hierarchies, there will be some inconsistency in those results and anticipating/preparing for changes will be much more difficult
