Sounds great, but...
This is a very interesting article, I think that IT professionals reading this should also bear in mind that implementing and pushing out a rules engine to process owners will bring it's own set of problems to the organisation.
Giving process owners the ability to change rules means that tighter restrictions and monitoring needs to take place. Its like giving a 10 year old an electric drill to help you build a chair. Sure he can probably help you, but all of us know that we need to pay CLOSE attention to what he is doing, else there could be a very unfortunate accident.
It is the same with giving this to process owners. Many of them will not be aware of security requirements, change control procedures or segregation of duties needs. Very close monitoring needs to take place of these process owners, and one could question whether this is really more or less productive from a macro scale. In the long term (provided there is no staff turnover) it could be beneficial, as more reliance could be placed on these individuals as they learnt more about their responsibilities.
This is just something to keep in mind, and to moderate your overwhelming excitement of being able to get rid of this element of development. Caveat Developer.
