This is the ground-breaking new book for aspiring purchasing and supply chain leaders and anyone with a keen interest in this rapidly evolving field. For too long business has focused on short-term cost advantages through low-cost country sourcing with little regard for the longer-term implications of global sustainability. As the first book to fully address the environmental, social and economic challenges of how companies manage purchasing and supply chains, it aims to inspire the development of current and future purchasing and supply chain leaders. In addition to explaining the basic principles and processes of both purchasing and supply chain management, the book evaluates how to develop strategic and sustainable purchasing and supply chain management. A key message is that purchasing and supply chain management needs to focus on value creation rather than cost cutting. This requires the development of completely new purchasing and supply chain models that involve closed-loop supply structures, supply chain transparency and collaboration with new stakeholders in traditional sourcing and supply chain processes.Aimed at students, educators and practitioners the book integrates sustainability into each chapter as a core element of purchasing and supply chain management. Incorporating case studies from industry into each chapter, the book strikes a balance between theoretical frameworks and guidelines for implementation in practice.
