This study seeks to examine the relationship between TQM social and technical factors and their effects on organizational results, and takes the EFQM model as a reference. Moreover, through structural equation modeling (Partial Least Squares), the study hypothesizes and tests a mediation model between social factors, technical factors and overall results. The study uses a sample of 116 Spanish firms undergoing complete assessment processes according to RADAR logic. The results show that: (1) an open, flexible and continuous improvement oriented culture, a committed and involved leadership, and efficient management of human resources (TQM social factors) exert a direct and significant impact on the effectiveness of the quality system deployed (TQM technical factors) and on the results; (2) the management and improvement of processes, the alliances with suppliers and other partners, and the management of resources (TQM technical factors) also directly influence results; moreover, (3) this variable partially mediates the effect of social TQM practices on organizational results.
