The strategy allows business teams to receive capabilities progressively while retaining the existing core system. Automation and AI are introduced as parts of workflows with defined rules and owners.
Incremental modernization of a core system
Functional evolution of a core system through gradual releases and defined integration contracts.
The challenge
Manual assignment, rework and long turnaround times coexisted with a core system that had to remain operational. The evolution needed to prioritize visible improvements without requiring immediate replacement.
The solution
A phased modernization was planned using workflows, document routing, documented REST interfaces and knowledge and applied AI capabilities where the process allows. Each increment accounts for dependencies and third-party integration.
Case contributions
- Core system evolution organized into functional increments.
- Integration and contract definition considered alongside business priorities.
- Transition risk managed through gradual releases.
