Operational resilience has become crucial for the financial services industry, particularly in the U.K., in light of regulations like PRA SS1/21, which demand firms ensure the availability and resilience of critical services amid increasing technological complexity. Key requirements under these regulations include tracking impact tolerances, business service mapping, and testing critical systems. To manage these, financial firms can utilize observability solutions like Dynatrace, which automate the monitoring of service disruptions and provide tools for application mapping and synthetic testing. By setting service-level objectives for impact tolerances and using automated alerts, firms can preemptively address potential disruptions. Furthermore, business service mapping helps identify the necessary resources and personnel to maintain service continuity, while synthetic monitoring enables the testing of systems under various disruption scenarios. Although adhering to these regulations may appear burdensome, investing in compliance through advanced platforms can enhance operational resilience and deliver competitive advantages in digital service delivery.
