The impact of quality management practices on innovation: an empirical research study of Brazilian manufacturing companies

摘要

Purpose - The aim of this study is to investigate the effects of soft and hard quality management (QM) practices on innovation performance, considering innovation practices as a contextual variable mediating this relationship. Design/methodology/approach - Using data from 132 Brazilian manufacturing companies, partial least square-structural equation modeling (PLS-SEM) is employed to test if soft and hard QM practices, directly, affect innovation practices and, indirectly, innovation performance. This investigation also aims to identify whether the relationships are maintained regardless of the size of the company. Findings - The results suggest that soft QM has a positive effect on hard QM. However, only soft QM, not hard QM, has a significant effect on innovation practices. Additionally, soft QM has a significant positive effect on innovation performance through innovation practices. Company size does not influence the relationships. Practical implications - The findings can help managers to adjust their managerial practices to enhance the effective impact of QM on innovation performance. Originality/value - The previous literature presents conflicting results on the relationship between QM and innovation performance. Most studies have proposed a direct relationship between both constructs. This study considers innovation practices as a mediator in this relationship. Furthermore, this paper adds to the scarce literature reporting related studies conducted in developing countries.
