While its revals start planning their lines on average nine months before they hit the shelves, Zara has a reputation for instant reaction to fashion trends and rapid restocking of stores. Zara lines rarely stay on the shelves for more than one month. Zara can make on new line, from the initial concept to when it arrives in the shop, in just three weeks. In addition the Zara technology is very important and will be more important in the future. Designers are in daily contact with store managers, discussing which items are most in demand and which are not.
