Zara, part of Inditex, has become the world's largest fashion retailer by leveraging a technology-enabled strategy that embraces rapid inventory turnover and customer insight rather than traditional advertising and manufacturing practices. The company focuses on in-house production, quickly responding to customer demand with new styles delivered within weeks, highlighting its innovative approach compared to competitors like Gap. Zara's growth and profitability demonstrate the effectiveness of its model, allowing the brand to dominate the fashion industry while navigating the challenges of ethical manufacturing and global supply chains.
