The relationships between TQM, TPM, JIT and agile manufacturing : an empirical study in industrial companies

Purpose: This empirical study aims to explore the relationship between Total quality management (TQM), Total productive/preventive maintenance (TPM) and Just-in time (JIT). It also seeks to examine the relationship between Just-in time (JIT) and agile manufacturing. Design/methodology/approach: Data for the study were collected from a survey of 205 industrial companies and the relationships proposed in the framework were tested using structural equation modeling. Findings: The results indicate that (1) TPM has a positive impact on TQM and JIT, (2) TQM has a positive effect on JIT and (3) JIT has a direct positive relationship with agile manufacturing. In addition, the results reveal an indirect effect of TPM and TQM on agile manufacturing through JIT. Research limitations/implications: The conceptual model proposed and tested in this study can be used by researchers for developing Lean manufacturing practices (TQM, TPM and JIT) and agile manufacturing theory. In addition, this model shows to practitioners the importance of integrating TQM, TPM and JIT in manufacturing firms. In other words, this study shows practitioners how firms can support their agile manufacturing system. Originality/value: This research presents an innovative approach since it examines simultaneously the interdependencies between TQM, TPM and JIT and their direct and indirect link with agile manufacturing using structural equation modeling.
