The advent of information and communication technologies changed the fabric of business competition. Organizations are forced to redesign their internal activities and external relations in a way that will enable them meet customer expectations.

There is a strong need for designing effective supply systems based on strong supplier relationships, as the overall performance of the companies will hinge on the responsiveness of their supply chain system. This book provides comprehensive insight into buyer-supplier relationships by proposing a model of collaboration built on inter-organizational trust, information sharing and commitment. It is anticipated that the analysis reveals Turkish executives'' attitudes toward collaboration and should especially be useful to purchasing and supply chain professionals as well as the academics who would like to gain more insight on this issue.
