Impact tolerances are key measures in operational resilience, helping organisations define the thresholds for tolerable disruption to their critical services. For Metrobank, establishing impact tolerances for services such as cash deposits at branches, ATM withdrawals, and fraud detection is crucial in ensuring business continuity in the face of adverse events. By the end of this chapter, readers will understand how to assess the tolerable limits for downtime and data loss in CBS-1 processes and how these measures contribute to Metrobank's operational resilience framework. ### [![New call-to-action](https://no-cache.hubspot.com/cta/default/3893111/0430108a-ef49-43aa-ac7d-ee6bb474eba8.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/0430108a-ef49-43aa-ac7d-ee6bb474eba8) [Moh Heng Goh](https://blog.bcm-institute.org/ebook-or/author/moh-heng-goh) Nov 7, 2025 ###### Operational Resilience Certified Planner-Specialist-Expert ### [![New call-to-action](https://no-cache.hubspot.com/cta/default/3893111/2196d2c2-e6e2-49b4-ba01-e7d03071dd00.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/2196d2c2-e6e2-49b4-ba01-e7d03071dd00) ### [![New call-to-action](https://no-cache.hubspot.com/cta/default/3893111/0430108a-ef49-43aa-ac7d-ee6bb474eba8.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/0430108a-ef49-43aa-ac7d-ee6bb474eba8)**CBS-1 Deposit and Withdrawal Services** [![\[OR\] \[MBT\] \[E3\] \[CBS\] \[1\] \[ITo\] Establish Impact Tolerances](https://no-cache.hubspot.com/cta/default/3893111/9bcce43c-3843-495b-aeaf-e8f105df9c30.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/9bcce43c-3843-495b-aeaf-e8f105df9c30) In this chapter, we will explore the concept of setting appropriate impact tolerances for Metrobank's critical business services (CBS-1) related to Deposit and Withdrawal Services.

Each sub-CBS within this critical service has specific downtime and data loss thresholds that align with both customer expectations and regulatory requirements. By understanding and addressing the maximum tolerable downtime (MTD) and maximum tolerable data loss (MTDL) for each process, Metrobank can better manage risks and optimise recovery strategies. The actions outlined for improving resilience, such as enhancing system backups, upgrading infrastructure, and strengthening cybersecurity, are vital in ensuring minimal disruption during unforeseen events. Moving forward, these measures will enable Metrobank to maintain high-quality service delivery and meet regulatory compliance standards effectively.   | Building Resilient Banking Operations: The
