The document discusses the different types of quality costs in quality costing: prevention costs, appraisal costs, internal failure costs, and external failure costs. Prevention costs refer to activities that aim to prevent defects, and are generally the cheapest option. Appraisal costs evaluate products at stages to determine acceptability. Failure costs occur due to deficiencies, with internal failures before delivery and external failures after delivery to customers. Measuring quality costs can lead to benefits like higher productivity and customer satisfaction by focusing on prevention to reduce rework and inspection costs.
