Jedes dem Markt zur Verfügung gestellte Produkt und jeder erbrachte Service von Kühne + Nagel ist das Resultat verschiedener aufeinander folgender Aktivitäten. Für alle Import- und Export-Prozesse der See-und Luftfracht wird die Abfolge der spezifischen Benutzerinteraktionen mit Hilfe von BPMN modelliert und in der Camunda BPM Engine ausgeführt. Neben der Sequenz und Beziehung dieser Aktivitäten steht das verteilte und abteilungsübergreifende Arbeiten im Fokus. Die Zuordnung von Benutzeraufgaben erfolgt mit Hilfe von DMN-Entscheidungstabellen, welche basierend auf Stamm- und Geschäftsdaten eine Vielzahl von komplexen Ausdrücken beinhalten können. Da die Entscheidungen oft sehr komplex sind, werden anhand von Konfigurationsdialogen für den Anwender DMN-Tabellen generiert. Der Clou ist, dass die Entscheidungstabellen von den fachlichen Konfigurationen entkoppelt sind und der Anwender keinerlei Kenntnis über DMN besitzen muss.

14.  Business friendly
• Non developer can read DMN tables
• Minimizes the risk of misunderstandings between business and IT
• Non developer can model the rules that lead to a decision
• via Friendly Enough Expression Language (FEEL)
 … but error-prone
• via groovy as expression language

Solution idea (high level)
BPMCon 2017 – DMN on Steroids
 Use the advantages of DMN
 Authorized user can maintain the assignment rules via the business-
application
• custom authorization
• known look and feel
• custom proposal lists
• custom validation
• no knowledge about DMN needed
• technical “details” are hidden
 System generates DMN tables
• based on business-rules

16. 1610/26/2017
Solution
BPMCon 2017 – DMN on Steroids
 DMN-Generation is triggered when a rule is added, changed or removed
 Usage of the camunda DMN model API written in Java
• rules are processed in the order of the hierarchy
• expressions are inherited from parent
• each rule can contain multiple expressions
 Generated DMN is deployed to the engine via RepositoryService
 DMN evaluation is embedded within a task-assignment process
• BPMN-Process as a function (synchronous)
• Usage of the camunda-bpm-reactor1 extension
• Wrap delegate calls with new transaction
