What OMG DMN 1.4 - Decision Model and Notation for Automated Business Rule Workflows requires
OMG DMN 1.4 (Decision Model and Notation, 2023) defines a standardized graphical and machine-executable notation for expressing business decision logic in automated workflows. Core artefacts are Decision Requirements Diagrams (DRD) connecting Input Data, Decisions, and Business Knowledge Models; Decision Tables with seven hit policies (UNIQUE, ANY, PRIORITY, FIRST, COLLECT with operators, RULE ORDER, OUTPUT ORDER); and FEEL (Friendly Enough Expression Language) for predicate and expression evaluation. DMN bridges business analysts and technical implementors, enabling regulatory decision logic - including AML thresholds, credit scoring, benefits eligibility, tax calculations - to be tested, versioned, and deployed as executable rules.
