A finished pack is the end of a sequence that starts weeks earlier at a goods-in door. Each stage in that sequence has a decision attached to it, and a batch that fails one does not proceed to the next.

Materials Are Quarantined First

Raw material arriving on site is not usable stock. It is held, sampled and tested against its own specification, and only released into production once it passes. A vendor's certificate of analysis is a claim; the in-house test is the check on that claim.

In-Process Checks Beat End Testing

Weight, hardness, thickness and fill volume are checked while the line is running, not after it has stopped. Catching a drift at the two-thousandth tablet costs a few minutes; finding it at the end of the run costs the batch.

Release Is a Separate Decision

Manufacturing finishing and a batch being released are two different events, made by two different people. Quality assurance reviews the whole record — every in-process result, every deviation and how it was handled — before anything is authorised to ship.

Conclusion

Quality is not a test at the end. It is a sequence of decisions, each one documented, and the pack is simply what comes out when all of them were made correctly.
