The aim of this paper is to describe a conceptual alignment between the certainty-customization framework (Bäckstrand, 2012) and Kraljic’s purchasing matrix (Kraljic, 1983). This will enable companies that manufactures both standard and customer unique products to develop differentiated purchasing strategies for the constituent items based on the products competitive priorities and order winners. Through this distinction, different categories in the Kraljic-matrix needs to be handled differently based on the items position in regard to the customer-order-decoupling-point and its level of customization.
