Source records
The trace gets rebuilt before every audit
Auditors want every requirement traced through to a test. Most small and mid-sized manufacturers piece that together by hand.
Record maintenance and design review
A device lifecycle workspace built on DeX, set up to your design control procedure.
Keeping the record joined up
They link each record as it's added, flag anything missing, and work out what a change will touch before anyone approves it.
Approve every stage
E-sign at each design gate. Your CAD, PDM and document stores stay in place, connected by integration.
Follow a device record through design and release
Select a stage to see the records and reviewer roles involved.
Design control sized for a handful of products
Needs, requirements, risks, outputs, tests and documents, all connected.
Generated from the links. Gaps highlighted.
Hazards and controls on your ISO 14971 process.
Your phases, checklists, reviewers and e-sign.
Agent lists what a change touches and drafts the assessment.
