Purpose – The perceived advantages of the implementation of TQM are generating improved quality and efficiency, increasing customer satisfaction, thus improving competitiveness. However, there is a high failure rate in the implementation of TQM. The key issue in this regard is that companies have devoted relatively little attention to human resources management (HRM). Several academics and practitioners have asserted that synergy and congruence among HRM practices are critical to the implementation of TQM. However, there is relatively little empirical evidence to support this contention. The purpose of this research is to conduct an empirical study on high-tech firms, in order to analyse the impacts of HRM practices on the implementation of TQM. Design/methodology/approach – In this study, a research framework related to HRM practices, TQM practices, and quality performances was developed. Based on the framework, a questionnaire was designed and sent to the HR managers or chief executive officers (CEOs) of high-tech companies in Taiwan to investigate the effect of HRM practices on the implementation and practice of TQM. Findings – The study confirms that HRM significantly affects TQM practices. The study concluded that HRM practices have a significantly positive effect on the implementation of TQM. Implementing HRM practices can also have a significant effect on employee and customer satisfaction. It also positively affected “employees’ quality awareness” and “corporate image”. The quality performances were also significantly affected by the implementation of TQM. Research limitations/implications – The research limitation is that the empirical study was on high-tech firms in Taiwan only. However, the framework can be easily extended to other industries if survey results are available. Practical implications – Overall, successful implementation of TQM can lead to an increase in customer satisfaction, and then benefit corporate image. It can also improve the satisfaction and quality awareness of employees. Enterprises that devote themselves to the implementation of TQM also need to perform HRM aggressively, if they are to increase the firm’s performance significantly. Originality/value – In this research, a conceptual framework related to HRM practices and TQM practices was developed, which is a valuable reference for future research. This study confirms the impacts of HRM practices on the implementation of TQM, and several key practices can be investigated.
