Decision Explainer has setup objects that capture logs for how a rule or an expression set ran, making it easy for reviewers to explain the outcome of the rule to users. For example, a student wants to know why they received a lesser discount on their course fee than what they expected. With Decision Explainer, the student application reviewer can check the application's history and the expression set that's used to evaluate the application, and provide the student the reason for receiving a lesser discount.
