What is DMN?
DMN is the abbreviation for Decision Model and Notation. It is a notation standard used to describe and model decision rules. This enables the precise documentation of complex decisions and traceability for all parties involved. DMN is often used in business process management to represent decision processes in a structured way. Various recurring decisions are identified, rules for decision-making are defined, and finally, decision-making can be automated.
The notation can be integrated into BPMN by identifying decisions in the business process and considering them separately from the process. This allows for more flexible and faster changes to decisions compared to directly mapping decisions in BPMN without DMN.
Main elements of DMN
The main elements of DMN are as follows:
- Decisions: These are various decisions.
- Input Data: Input data elements are taken into account in decisions and/or business knowledge models.
- Business Knowledge Model: This is the element that contains the logic for decisions.
- Knowledge Source: These sources are internal or external and influence the decision.
