Challenge
A critical engineering application at the heart of the component lifecycle: more than 100 tables, scattered business logic, a tightly coupled system landscape and an ageing technical base with frameworks and operating system at end of support. An outage was not an option.
Solution
Step-by-step modernisation - from diagnosis to pilot to industrialisation, accelerated by AI and automation:
- Iso-functional migration without service interruption.
- Secured non-regression with step-by-step functional validation.
- AI in the delivery process for analysis, code migration and tests.
- Close involvement of the business side - the most important success factor.
A team of ten over six months.
Result
- ≈ 60% gain on the project - measured against the effort estimate without AI (excluding project management).
- Significantly reduced technical debt and measurably higher quality.
- An approach that can be applied across the entire application estate.
* Project: we owned the delivery · ● in operation: we run the solution today
