Overhaul of the Rating System for Non-Retail Third Parties

The NOVA project aimed to develop a new application replacing existing rating systems used by a leading European banking group to assess non-retail counterparties, including SMEs, large enterprises, sovereign entities and institutional clients. The platform calculates an internal credit risk score representing each counterparty's probability of default.

Client context

Business challenges

• Optimise and simplify the rating processes
• Design a target architecture and Information System ensuring maintainability and scalability
• Anticipate regulatory and compliance requirements
• Consolidate fragmented third-party rating and assessment systems
