System requirements
Quality System requirements for medical devices have been internationally recognized as a way to assure product safety and efficacy and customer satisfaction since at least 1983 and were instituted as requirements in a final rule published on October 7, 1996. The U.S. Food and Drug Administration (FDA) had documented design defects in medical devices that contributed to recalls from 1983 to 1989 that would have been prevented if Quality Systems had been in place. The rule is promulgated at 21 CFR 820.
