In this paper, we discuss a new architecture for integrating and executing business process models with rules. It is based on a workflow engine that runs a BPMN-based business process model. On the lower level, rules are used to express the specific parts of the business logic. Rules working in the same context are grouped into a single task in the process model. Such a rule task is modeled by a formally defined decision table, which is designed in a visual way and its quality can be formally verified. In the runtime environment, tables are executed by a dedicated rule inference engine controlled by a workflow engine.
