Any one of these you could find somewhere. What no stack of point tools can give you is all
of them on the same thread — so the whole lifecycle stays honest as it changes.
One model
The thread is intrinsic — not integrated
Requirements, architecture, tests, risk, and SBOM are records in one database, not systems wired together. Change one item — even a vulnerable component — and every linked item flags suspect for re-verification, automatically. No integration to drift, no seam to break.
Compliance
The audit trail writes itself
Every change is versioned with who, when, and why — as a by-product of the work, not a binder assembled before a submission. Verification shows coverage and gaps against your frameworks live, so an audit is a report you run, not a fire drill.
21 CFR Part 11
Electronic signatures, where it matters
Controlled transitions, approvals, and releases are signed with re-authentication and a recorded signature meaning — the binding, attributable signature Part 11 requires, enforced by the system rather than promised in a policy.
Risk + SBOM
Risk and the supply chain, on the thread
Score hazards on the ISO 14971 model, link mitigations to the requirements and tests that deliver them, and accept residual risk on the record. Import CycloneDX or SPDX, and when a CVE lands, every dependent item flags for re-assessment.
MBSE
Real model-based engineering, no round-trip
SysML elements — block, internal-block, parametric, state-machine — are first-class items in the same database as your requirements and tests. No ReqIF export-import, no drifting copies, no drawing pinned to a ticket.
AI
Quality AI that never touches your trace
Optional AI flags ambiguous, untestable, or incomplete requirements as you write them — on a model you bring. It assists the author; it never writes your traceability. The system of record stays yours.
Releases
A release is a signed evidence package
Bundle requirements, architecture, tests, and risks, baseline them as named snapshots, clear the readiness gates, and sign. The submission assembles itself from the evidence that actually exists — fixed to exactly what was approved.
Reporting
Reports and dashboards from live data
Coverage matrices, verification status, and risk burndown come straight from the system of record — export to Word, Excel, or PDF, or schedule them. You never rebuild a traceability matrix in a spreadsheet again.
