Quality assurance (QA)
Quality assurance (QA) or quality control (QC) are umbrella terms for many different methods, procedures and measures for achieving and ensuring defined quality requirements.
According to DIN EN ISO 9000:2015, quality assurance is the area of quality management that aims to create confidence in the quality of products. In Germany, quality assurance has become increasingly important since companies began to have their quality management systems (QMS) certified in accordance with the ISO 9001 series of standards established in 1987.
