Abstract
Following a total quality management (TQM) approach and the EFQM Model framework, this contribution aims to study the influence of TQM social factors on organisational results, by considering the TQM technical factors as a mediating variable in this relationship. Moreover, the effect of size and type of business on the implementation of TQM and results is analysed, as well as determining which TQM practices have a more important effect on the operational results. The research questions and hypotheses proposed in this research model are tested on a sample of 116 Spanish firms. The results support the reliability, validity and the high-predictive power of the EFQM Excellence Model as a framework for the implementation of TQM. Moreover, our findings indicate that TQM social factors provide a cornerstone for the success of the quality system. Similarly, TQM technical factors partially mediate the relationship between TQM social factors and results. It was also found that TQM social factors and processes management are the main predictors of operational performance. Finally, significant differences were found in TQM implementation, and in the key results of companies, based on their size; however, these differences are not significant based on the sector activity.
