The approach and methodology agreed for the SAR is used with optimum rigour within the size and scope of SAR commissioned. Analysis assumes a systems approach to safety and organisational reliability. It is anchored in relevant research and wider evidence base regarding effective clinical/professional practice and that of safety science. It draws on the full range of relevant information and input assembled, to evaluate and explain professional practice in the case(s) or the responses to earlier learning. Conclusions are of practical value, evidencing the wider learning identified about routine barriers and enablers to good practice, systemic risks and/or what has facilitated or obstructed change to date. There is transparency about any methodological limitations and the implications for the comprehensiveness or level of confidence in the analysis and findings.
