What the passport contains
- Identity: codes, manufacturer, model, location, criticality.
- Status timeline: every operational state change with who and when.
- Service trail: requests, work orders, PM cycles, calibrations.
- Documents: certificates and attachments linked to the device.
Why it matters
History no longer depends on staff memory or personal files. When auditors, vendors, or management ask what happened to a device, the answer is one timeline that is easy to retrieve and audit-ready.
