As part of the further development of a core banking system, the strategic extension of the business and application architecture was the focus. The goal was to enable the core system for open integration scenarios and new business models in the Open Finance context. At the same time, APIs had to be standardised, versioned and governed in a clean way – with high stability in operations.

For the business, a clearly defined core banking architecture meant the foundation for scalable integration and ecosystem strategies. Standardised REST APIs with clean lifecycle management enable faster partner integration, reduced integration costs and higher reusability of services. Positioning in the Open Finance space strengthens innovation capability and market attractiveness. The business case lies in modular extensibility, sustainable investment certainty and new value-creation potential.

Modernisation offered the chance to closely align business architecture (business capability modelling, value streams, business object models) and technical API architecture. Challenges lay in harmonising banking domain models, consistent versioning and governance of APIs and in aligning with industry initiatives for standardised account and payment interfaces.

Business and application architectures for an extended core banking system were defined and integration services and public APIs designed and owned. REST-based interfaces (OpenAPI/Swagger, JSON, XML) were built with clear governance and versioning principles. In parallel, there was active participation in industry-wide standards, including as co-stream lead for a Switzerland-wide account and payment interface. The result is a structured, open and future-proof core banking architecture.

We developed architecture frameworks, took on product responsibility for integration services and public APIs and positioned Open Finance strategically in the market. Through thought leadership and representation in industry bodies we combined business vision with operational implementation strength.

If you want to develop your core banking architecturally and embed Open Finance strategically, we support you from business architecture to productive API implementation – structured, market-oriented and future-proof.
