errors, and Ford emphasized standardization of design and component standards to ensure a standard product was produced. Management of quality was the responsibility of the Quality department and was implemented by Inspection of product output to 'catch' defects. Application of statistical control came later as a result of World War production methods, which were advanced by the work done of W. Edwards Deming, a statistician, after whom the Deming Prize for quality is named. Joseph M. Juran focused more on managing for quality. The first edition of Juran's Quality Control Handbook was published in 1951. He also developed the "Juran's trilogy", an approach to cross-functional management that is composed of three managerial processes: quality planning, quality control, and quality improvement. These functions all play a vital role when evaluating quality. Quality, as a profession and the managerial process associated with the quality function, was introduced during the second half of the 20th century and has evolved since then. Over this period, few other disciplines have seen as many changes as the quality profession. The quality profession grew from simple control to engineering, to systems engineering. Quality control activities were predominant in the 1940s, 1950s, and 1960s. The 1970s were an era of quality engineering and the 1990s saw quality systems as an emerging field. Like medicine, accounting, and engineering, quality has achieved status as a recognized profession As Lee and Dale (1998) state, there are many organizations that are striving to assess the methods and ways in which their overall productivity, the quality of their products and services and the required operations to achieve them are done. Medical devices The two primary, state of the art, guidelines for medical device manufacturer QMS and related services today are the ISO 13485 standards and the US FDA 21 CFR 820 regulations. The two have a great deal of similarity, and many manufacturers adopt QMS that is compliant with both guidelines. ISO 13485 are harmonized with the European Union Regulation 2017/745 as well as the IVD and AIMD directives. The ISO standard is also incorporated in regulations for other jurisdictions such as Japan (JPAL) and Canada (CMDCAS). 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.
