A medical facility tells patients test results late, causing anxiety. Which cost of quality applies?

Appraisal costs are associated with measuring and monitoring activities to ensure quality standards are met, such as inspections and testing. In this scenario, the issue is not about the quality control measures themselves but rather the failure to communicate results in a timely manner, which does not fall under appraisal costs.

Internal failure costs are incurred when defects are identified before the service reaches the customer, such as rework or scrap. The late communication of test results does not relate to internal failures since the patients have already received the service; instead, it reflects the consequences of that service not meeting patient expectations.

Prevention costs are investments made to prevent defects and ensure quality, such as training and process improvements. While important, they do not apply to the situation described, where the issue is the failure to deliver results promptly rather than a lack of preventative measures.
