Direct Cost (manufacturing cost) failure at supplier's site (bad) + Labor Cost (assembly and testing) + Overhead Cost (Inventory, handling, shipping costs) + Scrapping Cost (of part and attached parts assemblies: Sometimes assemblies cannot be disassembled and have to be scrapped altogether) + Rework (applying a new part instead)
Zero Defects is a management tool aimed at the reduction of defects through prevention. It is directed at motivating people to prevent mistakes by developing a constant, conscious desire to do their job right the first time." [2]: vii — Zero Defects: A New Dimension in Quality Assurance

DRBFM is implemented based on novelty of change at any level of the product (design, process, supplier, etc.). The intent of the DRBFM is to make these changes visible by discussing them at length, as well as every possible concern for failure that may potentially occur - anything that impacts quality, cost, or delivery.
