For a manufacturer, being able to trace a specific faulty keyboard back to its serial number is essential for quality control. Suppose a batch of 10,000 keyboards is produced, and a particular model shows a high failure rate on the “Enter” key. By examining the batch logs, the factory can identify which units failed, correlate those failures with the serial number range, and then investigate whether a specific component lot or assembly line was responsible. The logs also serve as legal proof that a keyboard was tested and passed before leaving the factory.
