Requirement text
Design transfer activities shall ensure design outputs are verified as suitable for manufacturing before becoming final production specifications.
What changed
Part 820.30(h) required that each manufacturer establish and maintain procedures to ensure the device design is correctly translated into production specifications. This was a brief requirement focused on the accuracy of translation from design to manufacturing.
ISO 13485:2016 addresses design transfer through two related clauses. Clause 7.3.8 (control of design and development changes) and clause 7.3.9 (design and development transfer) together create a more comprehensive framework. Note the numbering difference: Part 820's transfer section 820.30(h) maps to ISO 13485 clause 7.3.9, not 7.3.8, because ISO 13485 inserts design changes (7.3.8) before transfer (7.3.9) in its clause sequence.
ISO 13485 7.3.9 requires documented procedures for the transfer of design and development outputs to manufacturing. The outputs must be verified as suitable for manufacturing before becoming final production specifications. This is more rigorous than Part 820's 'correctly translated' language — ISO 13485 requires positive verification of manufacturing suitability, not just accuracy of translation.
The QMSR framework also shifts design transfer from a singular event to a more continuous process. Under Part 820, many companies treated transfer as a one-time handoff at the end of development. ISO 13485's integration of transfer into design planning (7.3.2) and its emphasis on manufacturing verification means transfer activities should occur progressively as design outputs mature, with formal verification at each stage.
Additionally, ISO 13485 7.3.9 explicitly requires that transfer procedures ensure design outputs are complete and adequate before release to manufacturing. This creates a stronger gate function than Part 820's translation accuracy requirement, effectively preventing premature release of incomplete design packages to production.
Atomic constraints
- •Transfer procedures must be documented
- •Design outputs must be verified as suitable for manufacturing
- •Production specifications must be established
- •Documented procedures for the transfer of design and development outputs to manufacturing must be established per ISO 13485:2016 clause 7.3.9.
- •Design outputs must be verified as suitable for manufacturing before being released as final production specifications — not merely transcribed correctly, but confirmed to be producible using the intended processes.
- •Design transfer must demonstrate that production methods are capable of consistently producing devices that meet design output specifications.
- •Design outputs must be verified as suitable for servicing where applicable, ensuring service procedures and service specifications are captured before transfer is complete.
- •Transfer verification activities must be documented, including who performed the verification, what was verified, the method used, and the results.
- •Design transfer must be a progressive activity planned from the outset of design, not a single handoff event at the end of development.
Common gaps
No dedicated design transfer procedure
majorISO 13485 7.3.9 requires documented procedures specifically for design transfer. Many Part 820-era QMS libraries address transfer informally within the general design control SOP or treat it as the final step of the design control waterfall without a standalone procedure defining transfer activities, responsibilities, and acceptance criteria.
Design outputs not verified for manufacturing suitability
majorISO 13485 7.3.9 requires that design outputs be 'verified as suitable for manufacturing before becoming final production specifications.' Many companies transfer design documents to manufacturing without formal verification that the outputs are actually producible — leading to manufacturing deviations and process adjustments after transfer.
Transfer treated as single event rather than progressive process
moderateThe QMSR framework expects design transfer to be integrated into design planning from the outset (per 7.3.2) and executed progressively. Many companies still treat transfer as a single handoff event at the end of development, missing opportunities for early manufacturing engagement and process development.
Incomplete transfer records
moderateTransfer is documented by a 'final BOM' release but lacks evidence that manufacturing capability was assessed (e.g., line qualification). ISO 13485 requires verification of suitability for manufacturing.
