Supply chain management is defined as the integration of key business processes, from original supplier to end-user, to provide products, services and information. Supply chain management has emphasised the overall and long-term benefit of all parties on the chain through cooperation and information sharing. In the current competitive context, information is a vital factor in any supply chain as a primary driver and it has become a crucial activity in supply chain management [2]. The proper information sharing within a supply chain allows firms to access data across their supply chains, allowing them to collaborate in activities such as sales, production, and logistics and ultimately enhance the supply chain performance through integrated information network [3]. However, the benefits of sharing information among supply chain members are not always the same as they depend on the supply chain structure and its operational characteristics. World leading companies have successfully adapted supply chain management concepts in to practice and have successfully reached to the competitive edge within their own market segments. For instance, Zara, Apple, Proctor & Gamble, Walmart have secured their supply chain through the established information sharing network and strategies based on information sharing and collaboration.
