Which term describes the quality failure when using a second machine to verify test results?

The term that describes the quality failure when using a second machine to verify test results is "Appraisal." Appraisal costs are associated with the evaluation and inspection of products or processes to ensure quality. In this context, using a second machine indicates that there is a need to confirm the accuracy of the test results from the first machine due to a lack of confidence in the initial testing. This situation suggests that additional resources are being used to assess the credibility of results, which aligns with appraisal activities.

In healthcare, maintaining high accuracy in test results is crucial for ensuring patient safety. When verification procedures such as using a second machine are necessary, it indicates that there may have been previously identified concerns or inconsistencies that require further evaluation. Thus, the need for additional testing and verification represents a cost arising from the appraisal process, aimed at preventing potential errors in patient diagnosis or treatment.
