The formulation of a strategy to determine whether defects exist is an important initial step in most product liability work. A generally accepted practice is comparison of the failed product against manufacturing or industry standards. The fishhook example, summarized in this article, did not provide an industry standard, and the actual failed part was missing. Therefore, other methods (study of parallel samples) were used to establish product inconsistency and demonstrate the lack of quality control in the manufacturing process. The process used to accomplish this demonstration is summarized.
