A medical facility calls patients after they have been treated to determine their level of satisfaction. Which cost of quality does this scenario illustrate?

Prevention costs pertain to expenses incurred to prevent defects and ensure quality before a service is delivered. These costs include training staff and improving processes to avoid issues from arising in the first place. In contrast, the scenario describes an action taken after the service has been provided, thus not fitting the definition of prevention costs.

Appraisal costs involve expenses related to measuring and assessing the quality of services or products to ensure they meet quality standards. While patient feedback can be a form of appraisal, it occurs after the treatment rather than as a measure of quality during the service, making it less applicable in this context.

Internal failure costs are incurred when defects are identified before delivery to the customer, such as rework or scrap. The scenario does not describe any failure occurring within the facility before service delivery; rather, it focuses on evaluating patient satisfaction after treatment, which does not align with internal failures.
