Quality failure cost analysis

Faults occur during the assembly of apparatus, as a result of weakness of design, faulty materials, errors in process methods, and human mistakes. Each fault costs money to repair, the cost appearing in the final price of the product. A method of organizing production/inspection, fault information analysis, and costing to discover and control the quality failure costs arising during assembly of television receivers is given. Detailed information, not only of the reject percentages, but also of the related costs resulting from faults occurring during manufacture, is produced and made available to designers, production engineers, suppliers, and factory management. The main causes are located and permissible expenditure to produce an improvement in quality and reliability without increasing the price is derived. Experience shows that there is a correlation between assembly failures in the factory and service costs in the field.
