Relationships among TQM, TPM and JIT and Performance

In order to investigates the relationships among TPM (Total Productive Maintenance), TQM (Total Quality Management) and JIT (Just-in-Time), as well as the impact of implementation JIT on the company's performance, this study builds up the conceptual model based on literature review and conducts a survey of 118 manufacturing companies in the Pearl River Delta region of China by questionnaires. It shows that (1) there is a strong relationship between TPM and TQM. Both TPM and TQM effects on JIT directly; (2) JIT can improve operational performance; (3) JIT impacts the financial performance through operational performance. Hence, the Chinese manufacturing enterprises may improve performance through JIT, before which, they can implement TQM and TPM first, to achieve higher performance.
