Case Study: National Australia Bank achieves enterprise-wide process transparency and a 158% increase in automated controls with SAP Signavio

National Australia Bank Enabling Enterprise-Wide Strategic Transformation

National Australia Bank (NAB), one of Australia’s largest banks with 33,000 employees, needed greater process transparency and stronger, outcome-focused controls to meet regulatory obligations, manage risk, and improve customer outcomes across its critical processes. The bank’s challenge was to establish an intelligent, process-aligned controls environment that reduced failures and enabled scalable, automated controls enterprise-wide.

NAB implemented the SAP Signavio Process Transformation Suite—combining process modeling, process mining, a collaboration hub, and governance—supported by a controls center of excellence to create a single source of truth and democratize process ownership. The transformation produced over 4,000 process models, a 158% increase in automated controls, simplified processes that shortened home‑lending approvals (about 35% of simple home loans approved unconditionally within an hour), and stronger, enterprise-wide control management.
