This study examines the roles of e-Kanban, enterprise resource planning (ERP), and lean production practices (LP) in enhancing supply chain collaboration (SCC) and operational performance in Indonesian automotive supply chains. Employing a mixed-method approach, we integrate a case study of a focal company with a survey conducted among 152 tier-1 suppliers. The relationships between these systems and practices were analysed using structural equation modelling (SEM). The results indicate implementing e-Kanban alone does not inherently improve lean operations; however, user satisfaction with these systems significantly boosts the effectiveness of LP. The integration of e-Kanban and ERP systems, particularly when aligned with just-in-time principles, improves key operational metrics such as cost efficiency, product quality, lead time, productivity, and flexibility, which positively influence SCC and overall performance. This study also provides practical insights for practitioners and highlights the need for further exploration of ERP and LP integration in diverse supply chain contexts.
