QC During NPI: Build Quality In Before Mass Production

Episode 330 of China Manufacturing Decoded features hosts Adrian and Renaud from the Sofeast Group discussing why quality control should not start when finished products come off the production line. By then, many key decisions have already been made: product requirements, supplier selection, component choices, tooling, process setup, inspection methods, and testing plans.

In this episode, Adrian and Renaud explain what quality control should look like during the NPI process, before mass production begins. They discuss why final inspection is only one part of the quality picture, how clear product requirements reduce confusion, why supplier and component qualification matter, and how process controls, inspection points, test methods, jigs, fixtures, and pilot runs help prevent defects before they become expensive production problems.

You’ll learn why quality needs to be built into the product and manufacturing process from the start, rather than being inspected in at the end.

The main takeaway: final inspection may catch problems, but it does not prevent them. Good NPI quality control reduces risk earlier, when changes are easier and cheaper to make.
