Adrian revisits a classic episode (originally Ep. 30, Nov 2020) in this monthly rewind, Episode 333 of China Manufacturing Decoded, and sits down with Sofeast CEO, Renaud, to unpack the three types of quality-control (QC) plans every importer and manufacturer should agree before production starts.
Renaud explains three types of QC plans:
The product quality control plan, often linked to the manufacturing contract.
The process control plan, which controls quality during production rather than waiting until the end.
The QC plan for new products, which helps buyers and suppliers think through risks before mass production starts.
Key takeaways for listeners: QC planning is a pre-production activity not a rescue job; define a clear product quality standard; decide how quality will be controlled during production; and for any new product, agree on what must be proven before mass production. If any of those points are unclear, that’s likely where your next quality risk is hiding.
