Zara has developed a highly responsive supply chain that enables it to deliver new fashion items to stores within 2 weeks. This allows Zara to respond rapidly to emerging trends. Key aspects of Zara's supply chain include closing the communication loop between customers and designers, maintaining a consistent rhythm across the entire chain, and leveraging its production and distribution facilities for flexibility. While very effective for Zara, its model may not work for all retailers as it relies on Zara's expertise in fast fashion and ability to quickly change products based on customer feedback.
