Apparel manufacturing is based on rapid and quick-response supply chains; with such a context, it becomes highly challenging to manage dynamic demand, greater lead times, global sourcing networks, and short product life cycles. The importance of the digital supply chain in recent years’ digital technologies have become instrumental in driving efficiencies and competitive advantage throughout the extended enterprise. This paper focus on the potential contributions of Enterprise Resource Planning (ERP), Artificial Intelligence (AI), Internet of Things (IoT) and digital Supply Chain Management (SCM) platforms to increase supply chain efficiency in apparel manufacturing, especially in Bangladesh’s Ready-Made Garments industry. The research employs a qualitative approach based on literature and systematically reviews academic papers, industry reports and recorded cases concerning the digital supply chain transformation. The results show that ERP systems increase process integration and inventory control, AI increases demand forecasting and decision-making accuracy, IoT provides for real-time visibility and monitoring and digital Supply Chain Management (SCM) platforms support the end-to-end coordination and cooperation between supply chain partners. Together these technologies lead to shorter lead times, minimized inventory levels, enhanced delivery performance and greater supply chain flexibility. However, barriers such as the high cost of implementing such technologies, and quality issues around data along with a lack of digital skills and infrastructure continue to be major concerns for many businesses particularly smaller manufactures. The paper finds that strategic use of digital technologies with organizational readiness and policy interventions can be an important enabler for sustainable supply chain efficiency in the apparel manufacturing.
