Does rational culture matter in the relationship between lean manufacturing practices and operational productivity?

PurposeThis paper aims to examine the role of rational culture in the relationship between lean manufacturing practices and operational productivity in the machinery and equipment industry.Design/methodology/approachThis study uses a cross-sectional quantitative approach to conduct the research. Using an online survey questionnaire, 118 responses were collected. SPSS was used to assess validity, reliability and hypothesis testing of the study variables. Hierarchical regression analysis was employed to investigate the moderating effects of rational culture.FindingsThe study results reveal that quick setup and quality control were significantly related to operational productivity. Rational culture was a significant quasi-moderator.Practical implicationsThis study highlights the importance of quick setup and quality control for machinery and equipment firms to gain higher operational productivity. Rational culture could be used to drive the firms toward greater achievements in this regard.Originality/valueThe use of rational culture as a quasi-moderator in the relationship between lean manufacturing practices and operational productivity is unprecedented. This study offers new findings by introducing the role of rational culture to enhance the effects of lean manufacturing practices on operational productivity.
