Zara is balancing its in-house and outsourcing activities. For example heavy labour tasks like sewing and coloring are outsourced to companies close to its headquarter, often with bad reputation for mistreating its employees and poor compensations . On the other hand activities like design, prototyping and computer aided fabric cuts are held in-house to help agility. After clothes are assembled and return from the sewing factories, they are distributed to Zara's stores. To ensure that each order could arrive at destination punctually, laser barcode scanners, which are able to pick and sort over 80 000 pieces of clothes with a error rate of less than 0.5%, will be adopted in sorting the finished products
