It produces around 450 million items per year through a vertically integrated supply chain that allows new designs to reach stores in as little as 2 weeks. Zara's unique approach prioritizes responsiveness over cost reduction through short production cycles, 2,000 stores worldwide, and a centralized distribution center in Spain. This enables Zara to replenish stores more frequently and have 11,000 new designs annually, driving its competitive advantage in fast fashion.
