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 considered the most effective way to reduce overall quality costs. While appraisal and failure costs cannot be eliminated entirely, focusing on prevention through quality planning and assurance can significantly lower costs associated with inspection, rework, and issues that arise after delivery to customers. Measuring quality costs can help drive improvements in productivity, efficiency, and customer satisfaction.
