Some importers think of quality control as something that happens near the end of production. The goods are made, an inspector checks them, and the buyer hopes that any serious problems are found before shipment.
However, that approach is risky.
A final inspection can detect defects, but it usually cannot explain all the upstream decisions that created them. By that point, the product requirements may be vague, suppliers may already be selected, components may already be approved, tooling may already be made, and the production process may already be running.
That is why QC needs to be built into the NPI process.
Before mass production starts, buyers and manufacturers should define clear product requirements, qualify suppliers and components, plan incoming and in-process controls, prepare inspection and testing methods, review process risks, and use pilot runs to prove that the QC system actually works.
In this episode, Adrian and Renaud discuss the quality control processes that should be implemented during NPI and why preventing defects early is usually far cheaper than finding them later.
