Technical Documentation · EU AI Act Annex IV

Make technical documentation reviewable as governance evidence.

Technical documentation is not a PDF in a folder. Annex IV defines nine required sections — each with specific content requirements, each needing an owner, evidence, and a readiness status.

EAB tracks technical documentation completeness section by section — so gaps surface before audit, not during it.

EU AI Act Annex IV Section-by-section tracking Evidence per section
Technical Documentation · Annex IV Tracking
Nine Annex IV sections tracked independently
Named owner per documentation section
Evidence uploaded and linked per section
Readiness status: complete, in progress, missing
Completeness signal for supervisor approval
Maintained as system evolves, not a one-time PDF
Nine sections, each tracked as an independent governance object

Technical documentation as a maintained compliance record.

Annex IV completeness is not binary. Some sections may be complete while others have gaps. EAB makes the completeness state of each section visible — so work can be prioritised and gaps cannot be hidden.

Annex IV · Sec. 1–2

System Description and Development

General system description, intended purpose, and development process documentation. Each section has a named owner, required content fields, and an evidence upload area. Completeness is tracked, not assumed.

Annex IV · Sec. 3–4

Training and Validation Data

Training data provenance, validation methodology, and testing results — documented as structured governance records, not attached PDFs. Data documentation gaps surface before the approval review request.

Annex IV · Sec. 5

Monitoring and Oversight Documentation

Post-deployment monitoring arrangements and human oversight mechanisms — the section most commonly incomplete at audit. EAB links this section directly to the Human Oversight Documentation record to avoid duplication.

Annex IV · Sec. 6

Risk Management Documentation

The Annex IV risk management section is linked directly to the Article 9 Risk Management Record. Evidence uploaded in the risk record is available here — no duplication, one governed artefact serving two documentation requirements.

Annex IV · Sec. 7–9

Accuracy, Robustness, Cybersecurity

Metrics, testing results, and cybersecurity measures — each documented with evidence. Sections 7–9 often require input from technical teams who are not primary users of the compliance platform. Ownership assignments make this explicit.

Submission

Submittable, Not Just Referenceable

Technical documentation that can only be referenced but not submitted is not sufficient. EAB produces documentation that is exportable, structured, and demonstrably complete — section by section, with evidence and ownership.

From document existence to documentation completeness

Technical documentation that keeps pace with the system.

Documentation completed at registration may become incomplete as systems evolve. EAB tracks completeness continuously — not just at initial documentation.

1
AI System Owner

Complete Annex IV sections with structured content and evidence

Each Annex IV section has a structured workspace — required content fields and an evidence upload area. The owner works through sections in order. Section completeness is tracked as a measurable governance state.

2
Platform

Completeness signal generated for supervisor review

When sections are completed, the platform generates a completeness signal showing which sections are complete, in progress, or missing. The supervisor receives this signal before the approval request — not as a surprise during review.

3
Supervisor

Documentation completeness reviewed at approval

The supervisor reviews Annex IV completeness as part of the approval workflow. Incomplete sections can trigger a return request. Approval is only granted when documentation completeness meets the required standard.

4
Ongoing

Documentation maintained as system evolves

System changes — in architecture, data, deployment, or purpose — require documentation updates. EAB tracks which sections are affected by system changes and flags them for review. Documentation stays current, not static.

Technical Documentation Readiness · Annex IV

Track technical documentation completeness at section level.

A PDF in a folder is not Annex IV compliance. EAB tracks each section — with evidence, ownership, and a readiness status that can be shown to regulators.
