Basic Approach: Iterative
Develop a series of rules
Run rules on data with known results
Compare results from rules with results from experts
First Step: Translate original table into rules
Use interviews with experts or articulated principles as guide
Historical data gave expert results
Often low consistency between rules and known results
Next Steps: Refine rules
Discover systematic differences
Gather similar borderline cases and discuss with experts
