Decision Model and Notation
Decision Model and Notation (DMN) is a standardized modeling language for business decisions, developed by the Object Management Group (OMG). It provides a visual notation and XML schema for defining decision logic, enabling clear communication between business analysts and technical teams. DMN is used to model repeatable decisions in business processes, separating decision logic from process flow for better maintainability and automation.
Developers should learn DMN when working on business process automation, decision management systems, or complex rule-based applications, as it standardizes decision modeling across tools and platforms. It is particularly useful in industries like finance, insurance, and healthcare where regulatory compliance and auditability are critical, allowing for transparent and reusable decision logic that can be executed by Business Rule Engines (BREs).
