This literature review strives to gain an overview of theoretical frameworks used to analyse antecedents as well as outcomes of relationship quality, which is a core construct of research into relational governance of industrial buyer-supplier relationships. Given earlier findings that there is a lack of research into the performance impacts of relationship management or relationship quality, a special focus was laid on studies which include different kinds of performance measures. Furthermore, methodological approaches taken by the various researchers are closely examined. We derive some conclusions as to the state of the art as well as to potential future avenues of research in the field of business-to-business relationships. While generally, more theoretical integration and a consolidation of measures would benefit the disciplines, it is found that few studies exist which measure relationship quality, its antecedents and outcomes in agri-food chains.
