Vertical integration is the expansion within a company to grow its business areas at different points along the same production and sales path. Vertical integration can help companies reduce their costs while improving efficiency and flexibility. Zara, founded in 1975 by Amancia Ortega, is the world’s largest fast fashion flagship chain retailer owned by Inditex Group and is vertically integrated in all aspects of its business. Zara, according to Ferdows et al (2002), has a decentralized communication and decision making process based on an autonomous ordering of clothing and fulfillment method. Zara’s vertically integrated structure of owning everything from the processes of manufacturing and design of its products to the individual stores is due to the fact they produce more of their products in-house, with only forty percent of its activities outsourced. The outsourced activities include the simpler labour intensive quick turnaround activities such as sewing and basic clothing designs while in-house activities are the more complex, complicated and trendy designs for their clothing.
Zara’s top management’s opinion on the concept of most products produced in-house is it increases flexibility and speed as the products have a short cycle time. Zara also produces roughly half of its products within their own factories located in different regions around the world. Zara’s governance structure for gaining access to assets is continuous as they leverage their own assets, keeping their supply of materials within their parent company, Inditex Group. According to Ferdows et al (2002) some the supplies sourced and purchased from other Inditex firms include the dyes and fabrics used in the products. Vertically integrating allows Zara to control the whole supply and internal process chains while constantly introducing new products with lead times well above industry standards.
