The PAF paradigm is a quality cost strategy which comprises three broad categories: prevention, appraisal, and failure costs.
Money spent looking for errors.
yes Sort of: Total cost of quality is the sum of: - Prevention costs (doing what you can to reduce failures prior to production) - Appraisal costs (testing completed products prior to shipping) - Internal failure costs (reworking or scrapping defective items no shipped) - External failure costs (customer support and warranty, etc. Costs incurred for defects discovered after shipment)
Internal failure cost are quality costs that are associated with defects that have been discovered before delivery to customers. This internal failure cost is detected through inspection and appraisal activities.

Prevention cost is important in quality programs because it focuses on identifying and addressing quality issues at the source, before they escalate and result in costly rework or customer complaints. By investing in prevention measures, organizations can save money in the long run by reducing defects, improving efficiency, and enhancing customer satisfaction. This proactive approach helps create a culture of quality throughout the organization, leading to higher overall performance and competitiveness.
Data quality
Quality Control is generally recognized as the form of "control" that is based on inspection with the "quality police" making the quality. This is the forerunner of quality assurance where one should build a system that aims to remove the need for inspection by removing the possibilities for error. Prevention rather that detection

No. If internal quality failures such as defective component production are caught before shipping and current stock levels are high enough there can be no external failure costs. This is obviously a bit optimistic but it shows there is no necessary correlation.
