Audits force engineers to turn undocumented practices into traceable, risk-aware processes, showing how to build a compliant QMS for ISO 13485 and why that matters for product safety.
The audit was a catalyst that forced the engineering team to convert ad-hoc practices into a documented, risk-aware Quality Management System. By mapping every requirement of ISO 13485 onto concrete engineering artifacts, the piece shows why that rigor matters for patient safety and regulatory compliance.
A surprising focus was on evaluating external libraries, the so-called SOUPs. Instead of a simple "npm install," the team had to track provenance, maintenance status, and risk exposure for each package, assign responsibility, and define a re-evaluation cadence. This level of scrutiny turned a routine dependency into a documented safety gate.
Traceability was another pillar. The author described pulling BitBucket build numbers into the Unique Device Identifier (UDI) scheme, pairing them with Jira tickets, and automating UDI-PI updates. The result is a chain that lets auditors see exactly which code change landed in which version of the product, eliminating reliance on human note-taking.
Preparation tips boiled down to three actions: assemble a volunteer documentation taskforce, build a spreadsheet that cross-references each ISO 13485 topic with live examples, and ensure senior engineers keep their calendars clear for audit questions. With the right people and processes in place, the audit became a showcase of engineering discipline rather than a disruptive event.
