The ADVISORI approach to value creation: Business-case-oriented implementation: We identify and quantify the specific value drivers for your institution and optimise the implementation along these parameters.

Implementing BCBS‑239 presents financial institutions with complex challenges that go far beyond pure technical execution. At ADVISORI, we have developed a comprehensive approach that systematically addresses these multifaceted hurdles and significantly increases the probability of success. Typical challenges and our solution approaches: Data silos and fragmented system landscapes: Many banks struggle with historically grown, isolated system landscapes that make consistent data integration difficult. Our approach: We develop an integration strategy with gradual consolidation and establish a cross-cutting data layer that connects heterogeneous source systems without forcing immediate large-scale migrations. Data definitions and quality: Inconsistent definitions and quality issues with risk data are a core problem in BCBS‑239 implementation. Our approach: Establishment of a central data glossary with uniform definitions, supplemented by automated data quality controls and clear escalation processes for identified quality issues. Governance challenges: Unclear responsibilities and missing data ownership impede sustainable improvements. Our approach: Implementation of a structured data ownership model with clear roles and responsibilities, as well as the establishment of data stewards as a bridge between business and IT.

Demonstrating a successful BCBS‑239 implementation requires a multi-dimensional measurement approach that makes both regulatory compliance and business value transparent. ADVISORI has developed a comprehensive framework that systematically supports the measurement and communication of success both to supervisory authorities and internal stakeholders. Multi-dimensional success measurement framework: Compliance metrics: Systematic recording and documentation of the fulfilment of specific BCBS‑239 requirements with quantitative and qualitative indicators that make the maturity level transparent across each of the

14 BCBS‑239 principles. Process performance indicators: Measurement of efficiency gains in risk data processes, such as reduction of throughput times for risk reports, reduction of manual interventions and improvement of end-to-end data processing. Data quality metrics: Quantification of improvements in critical data quality dimensions such as completeness, accuracy, consistency, timeliness and traceability of risk data. Business value indicators: Capturing business value through improved decision-making, optimised capital allocation and reduced operational risks. ADVISORI's implementation approach for success measurement: Baseline assessment: At the start of the project, we establish a detailed baseline measurement of all relevant metrics to make progress measurable.
