<![CDATA[The impact of technology integration and organisational support on the effectiveness of Warehouse Management Systems (WMS) in manufacturing companies is examined in this study, along with their effect on supply chain performance. A quantitative methodological approach was adopted, employing Structural Equation Modelling–Partial Least Squares (SEM-PLS) with SmartPLS as the analytical tool. The research model consists of four variables: technology integration, organisational support, WMS effectiveness and supply chain performance. The results of the SEM-PLS analysis indicate that technology integration has a significant positive effect on WMS effectiveness (β = 0.478, p < 0.001), as does organisational support (β = 0.452, p < 0.001). Furthermore, WMS effectiveness significantly improves supply chain performance (β = 0.430, p < 0.001) and mediates the effects of technology integration and organisational support on supply chain performance. The model explained 73.0% of the variance in WMS effectiveness and 72.5% of the variance in supply chain performance, indicating substantial explanatory power. The findings demonstrate that successful WMS implementation depends on technological integration and strong organisational support, including management commitment and employee readiness. By improving warehouse operational effectiveness, organisations can achieve better supply chain performance. This research contributes to supply chain management literature, providing practical guidelines for developing effective, integrated WMS implementation strategies.]]>
