The decision logic is not buried in source code.
Anyone can look at the decision logic and
immediately understand it.

5. Why DMN: Flexibility
The decision logic can be changed without
touching your application.

6. Why DMN: Traceability

the decision history, providing you also with
helpful information like usage statistics.
