How to Conduct a Successful Factory Quality Management System Audit

Factory QC culture varies significantly across China. Export-oriented factories in Guangdong and Zhejiang typically have robust QC systems. Domestic-focused factories may have minimal QC. The most reliable indicator is whether the factory has dedicated QC staff separate from production staff. A factory where production workers also do QC inspection is a red flag. Independence of the QC function from production pressure is essential.

The most common quality problems I've seen across thousands of inspections are: (1) dimensional deviation — products not matching spec measurements, (2) color variation — especially between sample and bulk, (3) surface defects — scratches, dents, rust, (4) packaging damage — inadequate protection, wrong materials, (5) mix of good and defective units in the same carton. A solid QC plan addresses all five.
