The EU AI Act uses a risk-tiered approach:
Prohibited uses are banned, high-risk systems are subject to obligations around risk management, data governance, technical documentation, logging, transparency, human oversight, accuracy, robustness and cybersecurity, and lower-risk uses carry lighter transparency duties.
Implementation is phased:
Prohibited-practice and AI-literacy provisions began applying in 2025, general-purpose AI and governance provisions apply from 2025, transparency obligations apply from 2026.
High-risk obligations are subject to later application dates, including 2 December 2027 for certain stand-alone high-risk systems and 2 August 2028 for high-risk AI embedded in regulated products, following the current Commission guidance on the updated timeline.
The Act’s requirements for traceability, human oversight and record-keeping are, in substance, the same disciplines as named ownership, kill switches, audit trails and evaluation pipelines. [8]
The practical implication for executives is that an enterprise which builds the accountability model described here is also building much of the evidence base a regulator will expect.
Conversely, an AI estate that cannot identify owners, scopes, data classifications and decision logs will struggle to demonstrate compliance under the Act and comparable regimes emerging elsewhere.
Sovereignty, data residency and the ability to audit and explain AI-driven decisions therefore become design constraints to be engineered from the start, not retrofitted under audit pressure.
