The purpose of this Primer is to explain and elaborate on the requirements of NAFEMS QSS 001:2007 [1], which is a supplement to quality standard ISO 9001:2000 [2] specialised for applications in engineering simulation. It is intended that the Primer is not industry or application specific. The Primer can be used to assist organisations in developing and implementing a quality management system, or in adapting to, or integrating with, an existing quality system. With the aid of the Primer, an organisation should be able to develop a quality management system either for internal application or for self- or third-party certification, as required, without undue reference to either ISO 9001 or QSS 001. For the purposes of clarity and completeness, the guidance given in this Primer exceeds the requirements stated in the ISO standard and the QSS.
