Typically, a supplier performs the FAI and the purchaser reviews the report.
The simplest form of quality control was a sketch of the desired item. If the sketch did not match the item, it was rejected, in a simple Go/no go procedure. However, manufacturers soon found it was difficult and costly to make parts be exactly like their depiction; hence around 1840 tolerance limits were introduced, wherein a design would ...

To do so requires an understanding of the product being manufactured and how inspection tasks can improve the quality control process. [3]
Inspection and measurement of the thickness of the different layers of an electronic chip using THz and X-ray radiation.
