Inspection governance

Quality control inspection in China, tied to release authority.

PartVerity connects the controlled drawing, characteristic risk, inspection method, coverage, evidence package and shipment disposition. Inspection is not presented as a substitute for capable production; it is a defined decision gate within the project route.

Decision premise

Release question: does the agreed evidence support the next commitment—and who has authority to accept an exception?

Control framework

Six elements of an evidence-led inspection plan

The plan is scaled to drawing complexity, process risk, production stage, lot size and customer requirements. Coverage is stated explicitly rather than implied by a report title.

01

Controlled requirement baseline

Identify the drawing revision, specifications, approved clarifications and any accepted deviations before inspection characteristics are selected.

Evidence route

Revision record, characteristic list and approved requirement baseline

02

Characteristic criticality

Separate fit, function, safety, interface, cosmetic and process-monitoring characteristics so effort follows consequence rather than convenience.

Evidence route

Critical-characteristic rationale and risk-linked control level

03

Method and capability

Match each required result to a credible instrument, fixture, test or document and record method limitations where they affect confidence.

Evidence route

Measurement method, resolution, calibration status and setup reference

04

Coverage and sampling

State whether evidence is first-off, in-process, final, sampled or 100% and define the lot or production stage to which it applies.

Evidence route

Inspection frequency, sample plan, lot identity and traceability

05

Result and exception control

Keep actual results, pass/fail criteria, deviations and non-conformance dispositions visible instead of reducing the record to a green status.

Evidence route

Dimensional results, defect record, NCR reference and disposition

06

Release authority

Define who may release, conditionally release, hold, rework or request customer disposition before shipment or the next production gate.

Evidence route

Named decision owner, release record and open-condition log

Decision evidence

Inspection evidence by project gate

One final inspection cannot retroactively control supplier selection, drawing ambiguity or a hidden process change. Evidence belongs at the gate where the exposure is created.

Project gateTypical evidenceHold when
Before production releaseClosed DFM, controlled revision, characteristic and method planRequirement or acceptance method remains ambiguous
First-off / FAIBallooned drawing, actual results, material/finish evidence where scopedCritical result, deviation or document is unresolved
In-processProcess checks, parameter or feature records at agreed frequencyTrend or exception has no containment decision
Final inspectionLot-linked results, visual criteria, quantity and packaging checksEvidence is incomplete or not traceable to the lot
Shipment releaseDisposition, NCR status, required certificates and packing recordAcceptance authority or open-condition status is unclear

Scope limits

What inspection does not prove

A sampled result does not prove every unit conforms.

A passed final inspection does not validate an unstable process.

A report without revision and lot traceability is weak release evidence.

Customer or regulated-sector requirements override general website guidance.

Standards context

Use external standards to define the decision—not to decorate a claim.

External context for attribute and variables sampling; the contractual inspection plan remains project-specific.
