Today’s global purchasing and supply management combines two main perspectives: sourcing and supply chain management. The main focus of sourcing is on searching and selecting suppliers, while supply chain management focuses on developing logistics and supply processes in collaboration between supply chain partners. Our research agenda focuses on the challenges in combining sourcing and supply chain management perspectives. The tentative research perspectives in our research agenda include the following: the management system for global purchasing and supply management, evolution of purchasing and supply management, purchasing and supply management capabilities in a globally operating firm, and attractivity of the buying firm towards desired suppliers.
