The raw data comes from quantitative and qualitative approaches. Sales and replenishment reports are examined hourly by the Zara’s store managers. On the other hand store managers order items themselves instead of relying on what has being sent from the headquarters. The accuracy of their forecasting affects their compensation, which makes them more responsible. Part of the qualitative data gathering is direct customer feedback given to shop assistants daily. Another one is after shop closes, the store manager and assistants turn to a recovery team and try to recall what happen during this day, as well as sort out tried, but unsold items in fitting rooms and try to find a pattern, which can be fed to the design team.
