Introduction to Part I This first part is written for complete beginners. Imagine you have just left school or university and started your first job in a bank, insurance company, payment provider, or any other financial organisation in Europe. You do not need any previous knowledge of technology, law, or finance. Every new term will be explained the first time it appears, exactly as if you were hearing it for the first time. By the end of these five chapters you will understand why DORA was created, who has to follow it, how the law is built, why written policies are the most important tool, and the three simple thinking models (PDCA cycle, evidence-first mindset, and PRACI accountability) that make everything else in the book easy to follow.
