You will be asked to perform a number of tasks, ranging in complexity from implementing very simple decision and business rules to creating relatively complex business logic flows that require the use of conflict resolution techniques to ensure that the various rules fire in the correct order. You will be evaluated on how well your implementations meet objective criteria, such as producing a specific output given a specific set of inputs.

By passing this exam, you become a Red Hat Certified Specialist in Decision Management, which also counts toward becoming a Red Hat Certified Architect (RHCA®).
