Decision Model and Notation

Decision Model and Notation

Decision Model and Notation (DMN) is a standard published by the Object Management Group on 2014-01-16. Using this standard will ensure that decision models are interchangeable across organizations.

The DMN standard provides the industry with a modeling notation for decision management and business rules. The language is built to be readable by all its users in the business (as declared in chapter 1):

• the business people who manage and monitor the decisions,
• the business analysts or functional analysts who document the initial decision requirements and specify the detailed decision models and decision logic,
• the technical developers responsible for the automation of processes which use the decisions.

The DMN standard is complementary to the BPMN standard. The BPMN defines a special kind of activity, the Business Rule Task, which "provides a mechanism for the process to provide input to a business rule engine and to get the output of calculations that the business rule engine might provide".

Tools

Since the DMN standard is fairly young, there are not so many tools yet.
