Zara: The Responsive Supply Chain

Most fashion retailers forecast trends six to nine months out and pray they guessed right. Zara, the engine inside Inditex, built a system to read demand as it happened and put new styles in stores within weeks. By keeping much of its manufacturing close to home in Spain and nearby, it paid more per unit but bought radical flexibility: small initial batches, fast reorders on what sold, and daily signals from store staff feeding straight back to design and production.

This case sharpens a strategic decision most operators treat as purely logistical: how your supply chain's structure shapes what bets you're forced to make and when. It reframes forecasting itself as a choice rather than a given, and asks where in your own business you're committed to large bets placed too far in advance. The mechanism is named; how to apply it is left for you.
