Rolando makes some great points in this one The Rules of Business Just Changed. Again. How Fast Can You Change? where he discusses how business rules can give you a critical edge through business agility.
This one - Business Intelligence and Business Rules Make Great Bedfellows - gives some good examples of how Business Intelligence and Business Rules can come together. I think it misses out on the last logical step for bringing business intelligence into business rules - the building of predictive analytic models that can be used in business rules.
