Requirements Traceability

Purpose

Ensure bidirectional traceability between requirements, hazards/risks, design, code, tests, and anomalies for medical device software.

When to Apply

  • All lifecycle phases; especially during changes and release preparation.

Requirements (testable)

  1. ID Schema: Use stable IDs for requirements (REQ-###), hazards (HZ-###), risks/controls (RISK-CTRL-###), design (DES-###), tests (TEST-###), and anomalies (ANOM-###). Rationale: unambiguous linkage.
  2. Bidirectionality: Maintain trace both forward (REQ->DES->CODE->TEST) and backward (TEST->REQ). Rationale: completeness and impact analysis.
  3. Automation: Generate traceability matrices from managed artifacts (reqs tool + code tags + test metadata). Rationale: reduce drift.
  4. Change Impact: For each change, update trace links and assess affected items/tests. Rationale: controlled updates.
  5. Evidence Storage: Store trace outputs as release artifacts; version them with builds. Rationale: auditability.

Recommended Practices

  • Keep a traceability.yaml or use ALM exports to CSV/HTML for submissions.
  • Include trace tags in code comments and test names.
  • Integrate trace checks in CI (e.g., missing links).

Patterns

Traceability entry (YAML):

yaml
# REQ-TRC-01
REQ-62304-102:
  design: [DES-PUMP-01]
  code: [pump_stop_on_door_open]
  tests: [TEST-410, TEST-411]
  hazards: [HZ-07]
  risks: [RISK-CTRL-19]

CI check (concept):

text
Validate: every TEST-* references a REQ-*; fail build on missing link.

Anti-Patterns (risks)

  • Trace only in one direction -> risk: missing coverage.
  • Manual spreadsheets without automation -> risk: drift and errors.
  • Unlabeled code/tests -> risk: broken trace in audits.
  • Trace outputs not baselined -> risk: mismatch to released build.

Verification Checklist

  • IDs consistent and present across artifacts.
  • Forward/backward traces maintained; gaps resolved.
  • Trace matrices generated automatically and stored per release.
  • Change impact updates traces and triggers required tests.
  • CI checks for missing/invalid links in code/tests.

Traceability

  • Central traceability.yaml/tool export; code/test tags; release-stored matrices.

References

  • IEC 62304 traceability (5.1–5.6).
  • ISO 14971 for hazard-to-control linkage.
  • FDA/MDR submission expectations for trace matrices.

Changelog

  • 1.0.0 (2026-01-04): Initial traceability skill with IDs, automation, and CI checks.

Audit History

  • 2026-01-04: Audit performed. Verified:
    • IEC 62304 traceability (5.1-5.6) references accurate
    • ISO 14971 hazard-to-control linkage correctly noted
    • FDA/MDR trace matrix expectations appropriate
