I like the idea of BR experts running workshops that deal with different rules representation and management problems. I volunteer to run a 2-hours workshop during ORF2009. I will take a half-page example with relatively simple loan verification rules that include mitigations (I received these rules from a major financial institution). Together with the audience we will develop 4 different representations of these rules using simple Excel tables and discuss pros and cons of each implementation. We may run the rules against different test scenarios using OpenRules or another BR product (it is really not so important). Hopefully, it would be a practical exercise that will demonstrate serious rules representation problems that come directly "from the trenches". Hopefully other people would suggest their own workshops. The ORF audience may appreciate interactive workshops more than standard presentations.
