Part maturity connects tooling development to reliable components. Parts must be assessed against defined product requirements, with deviations documented and validation evidence collected before wider integration.
Use the applicable project plan, approved engineering requirements and quality procedures as the authority for exact criteria. This guide provides a transferable structure; it does not replace customer-specific or company-approved requirements.
The APQP training framework associates this gate with agreement to deliver the first parts made from production tooling. Check tool status, part availability, measurement readiness, dimensional evidence, control plans, product-validation progress, supplier capacity planning, packaging readiness and process-audit actions.
Design Validation: checks component conformity to design requirements using parts produced from the tool before the manufacturing process is fully validated.
Process Validation: checks whether the intended manufacturing process, controls and operating conditions consistently produce conforming parts; it is not a repeat of Design Validation.
Use the approved APQP grid and applicable customer procedure for exact acceptance criteria; this public guide is a practical summary, not a substitute for controlled requirements.
See the APQP phase-to-gate map →PRATIXUS guidance: adapt this checklist to the product, manufacturing process, supplier setup and applicable customer requirements. Avoid sharing confidential project records in public resources.
