CBS-1 Retail & Digital Banking

Mapping dependencies for CBS-1 Retail & Digital Banking enables AmBank to clearly understand how critical retail and digital banking services rely on interconnected resources, processes, systems, and external parties to deliver uninterrupted customer outcomes.

In the context of operational resilience, dependency mapping goes beyond traditional process documentation by revealing how disruptions can propagate across functions, technologies, and third-party ecosystems, potentially impacting customer access to banking services, financial transactions, and regulatory obligations.

This chapter applies dependency mapping to each Sub-CBS within CBS-1, identifying what the service depends on, who is involved, and how these dependencies interact.

This structured view supports impact tolerance setting, scenario testing, and prioritisation of resilience investments, ensuring that AmBank can continue to provide safe, reliable, and compliant retail and digital banking services even during severe but plausible disruption events.
