D&D of products AND processes — supplemental (IATF only)
Plain-language summary
IATF widens design to include manufacturing process design and demands a documented D&D procedure; planning must include all affected stakeholders — APQP in all but name.
What the clause is really asking
Even a build-to-print supplier designs its manufacturing process: that design work needs the same discipline — documented process, multidisciplinary planning including (not limited to) project management, design/quality/manufacturing input, and supply chain involvement where relevant.
What auditors look for
Auditors ask the build-to-print plant: show me your manufacturing process design for this part — PFMEA, floor layout for the line, control plan development trail, who participated. 'We excluded design' does not answer; product design exclusion never covers process design.
Typical evidence
Documented APQP-style procedure; process design files (PFMEA, flow diagrams, control plans with development history); multidisciplinary team records.
How to comply — recommendations
Adopt the APQP five phases as your documented process even in simplified form. Keep attendance visible on PFMEA and control plan development — multidisciplinary is evidenced by names.
Common nonconformities
No documented process design procedure; PFMEAs written by one engineer alone; process design treated as excluded because product design is.
