Operational Resilience Metric

An Operational Resilience Metric is a quantifiable measure assessing an organization's ability to keep important business services (IBS) functioning through severe disruptions. Evolving from traditional BCM, it shifts focus from system recovery to service continuity. The concept aligns with ISO 22316:2017 (Organizational Resilience) and is mandated by regulators like the Basel Committee on Banking Supervision (BCBS) in its 'Principles for operational resilience' (d516). Unlike traditional metrics like RTO/RPO, which focus on system recovery speed, these metrics measure the performance and availability of the *service* itself under stress. This involves setting and testing against 'impact tolerances'—the maximum tolerable level of disruption—to ensure the firm can protect customers and market integrity.

Implementation involves three key steps. First, identify Important Business Services (IBS) and set corresponding impact tolerances, defining the maximum acceptable downtime. Second, design and conduct severe but plausible scenario tests, such as a major cloud provider outage or a sophisticated cyberattack. Third, collect data during these tests to calculate resilience metrics, such as 'percentage of critical payments processed within the 1-hour tolerance window'. A global bank used this to identify a single point of failure in its cross-border payment system. After remediation, its resilience metric improved, reducing potential downtime from 4 hours to under 30 minutes, achieving a 100% pass rate in regulatory audits.

Taiwan enterprises face three main challenges. 1) Resource Constraints: Many SMEs lack the budget and specialized expertise for sophisticated testing and modeling. 2) Supply Chain Complexity: High dependency on global third parties makes it difficult to assess end-to-end service resilience. 3) Evolving Regulations: Local regulations are still maturing compared to frameworks from the UK's PRA or the EU's DORA. To overcome this, firms can adopt a phased approach, starting with their most critical service. They should enhance third-party risk management by embedding resilience requirements in contracts. Proactively aligning with international best practices like the BCBS principles provides a robust framework that anticipates future regulatory demands.
