Use of decisions today – Automation of process tasks
5 Wilfried Kurth, Decision Modelling at AXA CH
e. g.: Automation of claims handling
Challenges
▪ Modifacation of existing systems
▪ Explicite process-orientation
▪ Missing digitized insurance product
▪ Missing digitized notification of loss

Possible further use – Subdivision of monolithic processes
6 Wilfried Kurth, Decision Modelling at AXA CH
▪ Advantages
Clear responsibility for each subprocess
Successive expansion of subprocesses
Independent change of subprocesses (mircoservice architecture)
▪ Current challenges: Acceptance in Business and IT
▪ Still thinking in monolithic processes
Determination of subprocesses
▪ Short running process («not waiting»)
Implementation
▪ Use of decisions vs. internal coding in workflow system

Recent considerations – Digitization of Insurance Products
7 Wilfried Kurth, Decision Modelling at AXA CH
Benefit promise for Household Insurance – a first approach
Challenges This decision model is only for
coverage check and benefitamount calculation
How can decisions bemade for many purposes, e. g. overview of all coverages?

Summary
8 Wilfried Kurth, Decision Modelling at AXA CH
▪ Requirements
Model-driven approach is needed
Change from application-centricity to process-orientation
Digitized input (notification, insurance product, …)
▪ Challenges
DMN is not that easy for business people
more than one way to execute decisions (web service, embedded engine, code generation)
some topics might have more attention (AI, ML, Bots, RPA, …)
