Preface

As a business analyst or business rules developer, you can use Decision Model and Notation (DMN) to model a decision service graphically in a decision requirements diagram (DRD). This diagram traces business decisions from start to finish, with each decision node drawing logic from DMN model decision elements such as decision tables. Red Hat Decision Manager includes full runtime support for DMN 1.1 and DMN 1.2 models at conformance level 3, but currently does not include a built-in DMN model editor. You can design your DMN models using a third-party DMN authoring tool and include them in your Red Hat Decision Manager projects for deployment and execution.

For more information about DMN, see the OMG Decision Model and Notation specification.
