When building BPMN workflows in Flowable, a common challenge is how to handle complex decision logic without cluttering the process model or burying logic in service tasks.
That’s where DMN (Decision Model and Notation) becomes a game-changer. 🧠✨
Instead of embedding decision rules in Java code or script tasks, we separate decision logic into DMN decision tables. Why?
✅ Clean Process Models: The BPMN model stays focused on the process flow, while DMN handles conditional logic separately.
✅ Easier Rule Management: Business rules can be maintained in a table format and updated without changing the BPMN.
✅ Better Collaboration: Business analysts and developers can work side-by-side — BPMN for the workflow, DMN for the decisions.
✅ Improved Reusability: A DMN decision table can be reused in multiple processes or even exposed externally via REST.
🛠 How We Use It in Flowable
In our Flowable projects, we call DMN decision tables using the Business Rule Task, passing process variables as inputs. Based on the output, we control gateways or drive process behavior.
📌 Example: A decision table to assign risk levels based on user profile data (age, location, behavior score). The result then determines which approval workflow to trigger.
