(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. According to current Good Manufacturing Practice (GMP), medical device manufacturers have the responsibility to use good judgment when developing their quality system and apply those sections of the FDA Quality System (QS) Regulation that are applicable to their specific products and operations, in Part 820 of the QS regulation. As with GMP, operating within this flexibility, it is the responsibility of each manufacturer to establish requirements for each type or family of devices that will result in devices that are safe and effective, and to establish methods and procedures to design, produce, and distribute devices that meet the quality system requirements. The FDA has identified in the QS regulation the 7 essential subsystems of a quality system. These subsystems include: Management controls; Design controls; Production and process controls Corrective and preventative actions Material controls Records, documents, and change controls Facilities and equipment controls all overseen by management and quality audits. Because the QS regulation covers a broad spectrum of devices and production processes, it allows some leeway in the details of quality system elements. It is left to manufacturers to determine the necessity for, or extent of, some quality elements and to develop and implement procedures tailored to their particular processes and devices. For example, if it is impossible to mix up labels at a manufacturer because there is only one label to each product, then there is no necessity for the manufacturer to comply with all of the GMP requirements under device labeling. Drug manufacturers are regulated under a different section of the Code of Federal Regulations: Organizations and awards The International Organization for Standardization's ISO 9001:2015 series describes standards for a QMS addressing the principles and processes surrounding the design, development, and delivery of a general product or service. Organizations can participate in a continuing certification process to ISO 9001:2015 to demonstrate their compliance with the standard, which includes a requirement for continual (i.e. planned) improvement of the QMS, as well as more foundational QMS components such as failure mode and effects analysis (FMEA). ISO 9000:2005 provides information on the fundamentals and vocabulary used in quality management systems. ISO 9004:2009 provides guidance on a quality management approach for the sustained success of
