Camunda 7.4 is the upcoming minor release of Camunda BPM.

4. DMN (Decision Model and Notation) is the new standard for Business Decision
Management.
DMN is developed by the OMG (Object Management Group), the same “guys”
behind BPMN and CMMN.
Related terms:
- Business Rules Management (BRM),
- Business Rules Engines,

DMN and Business Decision Management

5. Decisions play an important role in Business Processes:
Why Business Decision Management?

6. Example

7. Just like Processes, decisions are “Business Logic”.
1. Need to be understood by Business and IT,
2. Need to be implemented so
that they can be
a. versioned,
b. monitored,
c. changed quickly.
Decisions are Business Logic
