An effective quality management system governs quality for the system, subsystem or equipment over its life cycle, whose purpose is to minimise human error at each stage and so reduce the risk of systematic faults, applicable throughout the EN 50126-1 life cycle and evidenced in the quality management report of the safety case. Aspects the system controls and the report covers: how the organisation is structured; quality plans and procedures; requirements specification; control, verification and review of design; application engineering; purchasing and manufacture; identifying and tracing products; handling and storing them; inspection and test; non-conformances and corrective actions; packing and delivering; installing and commissioning; operating and maintaining; monitoring quality and feeding it back; documents and records; configuration management and control of change; staff competence and training; quality audits and their follow-up; decommissioning and disposal. Compliance is mandatory for SIL 1 to 4, the depth of evidence proportionate to the SIL (Table E.1 in 2003 numbering), with an EN ISO 9001 certified system the usual evidence.
