QC is not a final hurdle — it's a system. If you only define 'good' at the end, you'll find problems when it's too late to fix without moving the launch.
Set defect rules, sampling thresholds, and checkpoints before production starts. Then verify early with a first-article inspection, monitor drift mid-run, and confirm before goods leave with a pre-ship check. Three gates, each doing a different job, none of them optional.
The reference that holds it all together is the golden sample — the physical unit that passed every test. Lock it, store it with your supplier and your QC team, and measure every checkpoint against it. Production drift is normal; an agreed standard is what makes it catchable.

Frequently asked questions
Why is packaging QC a system rather than a final inspection?
Problems found only at the end are found too late to fix without moving the launch. Treating QC as a system means setting defect rules, sampling thresholds and checkpoints before production starts, then checking at three gates: first-article inspection, mid-run monitoring and a pre-ship check. Each gate does a different job and none is optional.
What should be agreed with a packaging supplier before production starts?
Agree the defect rules, sampling thresholds and checkpoints before the run begins. With those in place you can verify early with a first-article inspection, monitor drift during production and confirm with a pre-ship check before goods leave. Defining good only at the end leaves no room to correct course.
What is a golden sample used for in packaging QC?
The golden sample is the physical unit that passed every test, and it is the reference every checkpoint is measured against. Lock it, store it with your supplier and your QC team, and compare production to it at each gate. Production drift is normal, and an agreed standard is what makes drift catchable.
