Zara

Every major fashion brand operates on the same calendar. Design a collection nine months in advance, manufacture it overseas, ship it to stores, hope customers like it. Zara ignored this entirely. Amancio Ortega built the world's largest fashion retailer by compressing the entire cycle from design to store shelf to as little as two weeks. When a trend appears on social media on Monday, Zara can have a version hanging in stores by the following fortnight. No other fashion company on Earth can move at this speed. The supply chain is the business model. While competitors manufacture in Bangladesh or Vietnam to minimise labour costs, Zara produces over half its garments in Spain, Portugal, and nearby countries. The labour costs more. But the speed advantage is devastating. Zara produces in small batches, tests what sells, and doubles down on winners within days. If something does not sell, they stop making it immediately.
