Increasing competition and shorter product lifecycles have required the development of strategic partnerships among suppliers, manufacturers, distributors, retailers, and logistics companies. Collaboration levels have increased dramatically in the past three years and will continue to do so. They bring participants benefits that might otherwise be unattainable without these partnerships. In order to identify the best practices in collaborative logistics, this thesis will explore the various forms of collaboration that have been or currently in practice. These include collaborative forecasting and inventory management, transportation, distribution, and warehousing. Case studies will be used to highlight the benefits of each practice, challenges, and a general framework for organizations looking to implement them. Because collaborative logistics is a rapidly evolving area in supply chain management, the thesis will also provide a future outlook into the direction it is headed.
