Tracing all the dependencies that lead to a give outcome is not easy. Automatically drawing a dependency diagram for an entire decision service would help, but in the real world such a diagram could get very large.
It would be nice if we could have a report that contains hyperlinks that allows one to navigate around a decision service.
By allowing nodes to be expanded or contracted it becomes possible to manage very large projects.
By clicking on say, Premiums based on vehicle age we could bring up the definition:
Then clicking on premium would show all the places that attribute is referenced:
It would also be nice if we could generate an analysis of the values that attributes are actually tested against throughout the decision service. By bringing all the values for a given attribute together it becomes easier to spot such mistakes as testing for >x on one rule sheet but >=x on another rule sheet..
