Use the activity cost information to determine the percentages of total costs that are prevention, appraisal, internal failure, external failure, and not costs of quality producing product). Quality Cost Percent of Total Activity Cost Classification Department Cost Prevention Appraisal Internal failure External failure Not a cost of quality Total 4.
