IIA Three Lines Model (2020) for IT Directors

What does IIA Three Lines Model (2020) require of a IT Director?

The IIA's principles-based model for organising governance roles: what the governing body, management (which carries first-line and second-line work), internal audit (the third line) and external assurance providers each contribute, how they stay independent yet aligned, and how together they create and protect value.
