Building and managing a supplier base has been referred in the literature as a key issue of supplier management. Since the seminal work of Kraljic in 1983, scholars have proposed a number of models aimed at enhancing the effectiveness of supplier portfolio management. In the IMP arena, those models are often criticized as they seem to ignore the interdependencies between the existing dyadic relationships. Such interdependencies are the main focus of this paper. It has four objectives. To analyse the types of relationships linking suppliers and to understand the factors and dynamics underlying their creation and management. To uncover existing links between buyer-supplier and supplier-supplier relationships. To clarify how supplier relationships within the portfolio may impact the performance of the actors involved.
