Success in achieving both the internal and external types of integration is very important. Highly integrated supply chains (those that are successful in achieving many or all of these types of integration) have been shown to be better at satisfying customers, managing costs, delivering high-quality products, enhancing productivity, and utilizing company or business unit assets, all of which translate into greater profitability for the firms and their partners working together in the supply chain.
Integration involves a balance between barriers and enablers. Companies that work closely with their suppliers encounter problems such as corporate culture, information hoarding, and trust issues. For example, Häagen-Dazs and General Mills share information with their vanilla suppliers to increase yields and improve sustainability practices, but at the same time, there is a danger. Giving supply chain partners this information enables those partners to share it with competitors. On the other hand, integration can be improved through long-term agreements, cross-organizational integrated product teams, and improved communication between partners. These factors all aid in integrating supply chain operations.
