Which of the following is considered an appraisal cost?

Appraisal costs are those associated with measuring and monitoring activities to ensure quality standards are met. These costs are incurred to evaluate the products, services, or processes to determine their quality and conformity to specifications.

In this case, audits and inspections serve as classic examples of appraisal costs. They are essential steps in the quality control process, helping organizations identify defects before products reach customers. This proactive approach reduces the risks associated with defective products, ultimately saving costs related to rework, returns, and lost customer trust.

In contrast, the training of repair and customer service focuses more on operational activities rather than direct quality assessment, while field trials for new products are related to product development and market testing rather than ongoing quality assurance. Engineering changes refer to adjustments made to products or processes to improve quality but fall into the category of prevention or internal costs rather than appraisal.
