Technical Documentation (Technical File) — EU/UK aligned
EU AI Act Compliance Foundations EU/UK aligned
+ On this page
Key takeaways
- Build a single navigable technical file that proves safety, performance and compliance — not a pile of PDFs.
- Every claim links to evidence; every control links to owners, thresholds, tests, and results.
Scope & purpose
- Intended purpose, target users, environments, exclusions and dependencies; product variants.
- Regulatory mapping: AI Act title, sector laws, CE/UKCA routes, standards list (e.g., ISO/IEC 42001 family when available).
System architecture & context
- Diagrams of data flows, components, APIs, third-party services, monitoring, key custody and isolation boundaries.
- Operational modes (normal, degraded, paused); rollback and kill-switch architecture.
Data sources & governance
- Source registry with provenance/licences, lawful basis, cohort notes, retention; lineage graphs.
- Privacy engineering: minimisation, redaction, unlearning approach, DSR handling.
Models & training
- Model cards; training/finetune recipes; hyperparameters; guardrails; content filters; jailbreak protection.
- Supplier attestations for foundation models; constraints and intended use statements.
- Test plans and results: accuracy, robustness, bias/parity, safety red-team, and stress/load.
- Acceptance thresholds by cohort; unresolved gaps with risk rationale and roadmap.
Risk management cross-refs
- Link to RMS register items; control implementations; evidence (logs, dashboards, approvals).
Security & privacy controls
- Threat model; segregation, secrets, egress controls; anti-prompt injection; content moderation pipeline.
Human oversight & UI
- Operator roles, permissions, explainability widgets, uncertainty cues, and override mechanisms.
Post-market monitoring plan
- Metrics, alerts, sampling, escalation, and CAPA workflow; regulator notification triggers.
Change control & versioning
- Model/data versioning; release approvals; rollback criteria; waiver handling; periodic reassessment.
Evidence pack structure
- Index page; requirement→control→evidence matrix; snapshots per release; immutable incident bundles.
Technical file checklist
- Scope/architecture documented; data/model cards complete; evaluations attached; RMS & PMM linked; approvals signed.
