AI, automation, and vendor-supplied decision systems generate consequential decisions at machine speed. Your team still operates on a quarterly or annual cycle, reconstructing the record after the fact. The gap between when a decision is made and when audit can defensibly assure it widens every year.
Add the IIA 2025 Global Internal Audit Standards, third-party AI under Pattern 14, ISO/IEC 42001, and the regulator’s rising expectation of continuous monitoring — and the existing toolset (sample-based testing, year-end workpapers, retrospective questionnaires) cannot keep pace. The board does not want a retrospective. They want assurance, now.
Sample-based audit cannot assure machine-speed decisions. Continuous assurance can.
