Zara is very famous for its time based strategy. In order to launch a new product within 15 days, Zara uses a small lot production. A new product will be tested in pilot stores. If product sales is good, a larger batch will be ordered. Otherwise, remaining products will be removed from the shelves and sold as mark-down in other stores. This creates the perception among consumers that Zara's products are unique and you have to take it while stock lasts. Vertical integration contributes to the success of Zara, they own the majority of its production facilities and stores (this is the reason why Quick Response can be effectively implemented). Its automated distribution centers are strategically located between the center of populations so products are delivered to stores quickly. Zara also works with Air France, KLM Cargo and Emirates Air in order that they can coordinate directly with the airlines to make the outbound shipments to its stores and bring back some raw materials and semi-finished materials with return legs.
