Validation & compliance
Evidence to support your validation, and a clear line on who validates what.
How Invariant supports your validation and regulated use.
21 CFR Part 11 / EU Annex 11
A summary of how Invariant controls map to Part 11 / Annex 11 expectations. The full, maintained matrix — with an honest Implemented / Partial / customer-responsibility status per control — is Validation Accelerator Pack artifact A3.
| Expectation | Invariant control |
|---|---|
| Audit trail (who/what/when/why) | Per-org hash-chained, tamper-evident audit with reason-for-change |
| Electronic signatures | Signer identity, timestamp, meaning, credential re-verification, content binding |
| Signature/record linking | Signatures bound to content digest + linked audit entry; append-only |
| Access controls | Role-based access with organization scoping |
| Copies / exports | CSV/PDF exports via a versioned metric contract |
“Built to Part 11 / Annex 11 expectations” describes designed controls and tested behavior. It is not a statement that a deployment is certified or validated — that remains program specific.
Data integrity (ALCOA+)
How Invariant supports ALCOA+ data-integrity principles.
| ALCOA+ principle | Invariant support |
|---|---|
| Attributable | Every action records the actor (human/AI/system) and organization |
| Legible | Structured records; human-readable audit trail |
| Contemporaneous | Audit entries written atomically with the business change |
| Original | Source records retained; exports are derived copies |
| Complete | Reason-for-change on regulated edits; linked records |
| Consistent | Enforced lifecycle ordering + hash-chained sequence |
| Enduring | Append-only audit + signatures |
| Available | Verifiable on demand; exportable |
