# AI Risk Assessment **Purpose.** A structured assessment of what could go wrong with a specific AI system, how bad it would be, and what you are doing about it. For high-risk systems it is the core evidence that Art. 9 risk management is operating. **When to use it.** Before development for high-risk systems, before deployment for all systems, and again on material change. Review live high-risk systems at least annually. **How to use it.** Do it with the people who build and use the system, not about them. Assess risk to the people affected first and to the organisation second — that ordering is what the regulation expects, and it also surfaces the risks that later become reputational ones. --- ### System under assessment | Field | Value | |---|---| | System ID / name | [AI-00X] | | Accountable owner | [name] | | Purpose | [what it does and what decisions it drives] | | Risk tier | [prohibited / high / limited / minimal] | | Affects individuals? | [yes / no — how] | | Assessment date / assessor | [date] / [name] | ### 1. Prohibited practice screen Answer first. Any "yes" stops the assessment. - [ ] Deploys subliminal, manipulative, or exploitative techniques - [ ] Exploits vulnerability by age, disability, or social/economic situation - [ ] Performs social scoring leading to unjustified detrimental treatment - [ ] Predicts criminal offending based solely on profiling or personality - [ ] Builds facial recognition databases by untargeted scraping - [ ] Infers emotion in the workplace or in education - [ ] Performs biometric categorisation to infer protected characteristics - [ ] Performs real-time remote biometric identification in public spaces **Any box ticked → do not proceed. Escalate immediately.** ### 2. Harms assessment Assess harm **to people** first. | Harm type | Could it occur? | Who is affected? | Severity | Likelihood | Rating | |---|---|---|---|---|---| | Discrimination / unfair outcome | | | | | | | Loss of opportunity (job, credit, service) | | | | | | | Financial loss | | | | | | | Physical or psychological harm | | | | | | | Privacy intrusion | | | | | | | Loss of autonomy or ability to contest | | | | | | | Misinformation | | | | | | | Exclusion of a group | | | | | | Then to the organisation: regulatory, financial, reputational, operational. > **Ask who is worst affected, not who is average** > Aggregate accuracy hides concentrated harm. A system that is 95% accurate > overall can be systematically wrong about one group — and that group is > who will be harmed, and who will complain. ### 3. Technical risk | Area | Question | Assessment | Mitigation | |---|---|---|---| | Data quality | Is training data relevant, representative, current? | | | | Bias | Have you tested performance across subgroups? | | | | Accuracy | Does it meet the declared threshold? Where does it fail? | | | | Robustness | How does it behave on edge cases and adversarial input? | | | | Drift | How would you detect degradation? | | | | Explainability | Can you explain a decision to the person affected? | | | | Security | Injection, poisoning, extraction, leakage through output? | | | | Dependencies | What happens if the vendor or model changes? | | | ### 4. Human oversight | Question | Answer | |---|---| | Who reviews the output? | [named role] | | What information do they see? | | | Can they realistically override? How? | | | How long do they have per decision? | | | How would we know if they were rubber-stamping? | | | What training have they had? | | > **The rubber-stamp test** > If a reviewer handles hundreds of decisions an hour, or overrides almost > never, oversight is nominal. Measure override rates — a rate near zero is > a warning sign, not a success metric. ### 5. Transparency - [ ] People are told they are interacting with, or subject to, AI - [ ] AI-generated content is marked where required - [ ] Affected people can obtain an explanation - [ ] **There is a route to contest a decision**, and someone staffs it ### 6. Residual risk and decision | Residual rating | Justification | Accepted by | Authority | Date | |---|---|---|---|---| | [low/med/high/critical] | | [name] | Per Decision Rights & Escalation | [date] | **Decision:** Proceed · Proceed with conditions · Do not proceed Conditions: **[list, with owners and dates]** ### 7. Review | Trigger | Action | |---|---| | Material change of purpose or data | Full reassessment | | Incident involving this system | Targeted reassessment | | Annually (high-risk) | Full review — see {{default:high-risk-review-cycle}} | | Vendor model change | Targeted reassessment | --- ## Adaptation notes - **Small organisations:** Sections 1, 2, and 4 are the irreducible core: is it allowed, who could it hurt, and who is watching. That fits on two pages. - **Regulated financial services:** Align with model risk management: add model validation findings, and treat this as a complement to, not a replacement for, independent validation. - **Where a DPIA is also required:** Run them together and cross-reference. Section 2 harms feed the DPIA's risks-to-individuals directly — see Processing & DPIA Log. - **Research and experimentation:** Apply a shortened version at experiment stage, and the full assessment before anything touches real users or real decisions. --- *From the [Open Data & AI Governance Kit](https://lsdeva.github.io/governance-kit/).
