Abstract Since its inception, the Kraljic Portfolio Matrix (KPM) has been widely used as a diagnostic and prescriptive purchasing tool. One of the primary weaknesses of the KPM is the qualitative nature of the model, which results in a subjective method for weighting and positioning suppliers or commodities in the various quadrants. In an effort to help overcome this widely cited weakness, this research proposes an objective, quantitative decision analysis approach to position products and services within the KPM. Single attribute value functions are used to quantify the strategic purchasing attributes of the KPM. A multi attribute value function is then used to quantify and rank-order products and services within the KPM based on the two strategic purchasing objectives. We empirically demonstrate this approach using data from an organization with a $10 billion purchasing portfolio. Furthermore, we illustrate how a cost-benefit view of the results help decision makers quickly and easily identify the products and services most conducive to the implementation of commercial best practice purchasing strategies. A sensitivity analysis advocates the robustness of our approach.

Indirect activities often represent an underemphasized, yet significant, contributing source of costs for organizations. In order to manage indirect costs, organizations must understand how these costs behave relative to changes in operational resources and activities. This is of particular interest to the Air Force and its sister services, because recent and projected reductions in defense spending are forcing reductions in their operational variables, and insufficient research exists to help t...

Current constraints in the fiscal environment are forcing the Air Force, and its sister services, to assess force reduction considerations. With significant force reduction comes the need to model and assess the potential impact that these changes may have on support resources. Previous research has remained heavily focused on a ratio approach for linking the tooth and tail ends of the Air Force cost spectrum and, although recent research has augmented this literature stream by providing more st...

Abstract : Recent and projected reductions in defense spending are forcing the military services to develop systematic approaches to identify cost reduction opportunities and better manage financial resources. In response, the Air Force along with her sister services are developing strategic approaches to reduce front-line mission resources, commonly referred to as the Tooth . However, an underemphasized contributing source of costs are mission support activities, commonly referred to as the Tai...

This paper explores how a firm is able to consider the value co-creation potential of its suppliers, mediate the goals and actions of both its external and internal stakeholders, and develop strategic supplier partnerships that go beyond compliance to contractual agreements to innovative value co-creation activities. The study contributes to filling a knowledge gap in understanding the process of value co-creation in a service context by providing empirical evidence, by means of case-based actio...

A great deal of research has focused on supply chain risk management, but the question “Which supply chain characteristics increase the frequency of supply chain disruptions?” has not received much attention from empirical research. This is a relevant question, because firms seek stability in their operations, and therefore managers need to know how the structure of their supply chains affects the occurrence of disruptions. The present study addresses this issue with a specific focus on upstream...

Economic systems are increasingly prone to complexity and uncertainty. Therefore, making well-informed decisions requires risk analysis, control and mitigation. In some areas such as finance, insurance, crisis management and health care, the importance of considering risk is largely acknowledged and well-elaborated, yet rather heterogeneous concepts and approaches for risk management have been developed. The increased frequency and the severe consequences of past supply chain disruptions have re...

This study adopts a power perspective to investigate sustainable supply chain relationships and specifically uses resource-dependence theory (RDT) to critically analyze buyer-supplier-supplier relationships. Empirical evidence is provided, extending the RDT model in this context. The concept of power relationships is explored through a qualitative study of a multinational company and agricultural growers in the UK food industry that work together to implement sustainable practices. We look at mu...

The purpose of this study is to further understand the relationship between purchasing strategies practiced by less-powerful buyers and their purchasing power. Drawn on the resource dependency theory, a two-way relationship was predicted where power is both a cause and an effect. The theoretical predictions were then explored in a multiple-case study in the context of vaccine procurement for developing countries. This context presents an asymmetric power situation, favoring suppliers, and change...

Abstract Recent protectionist trends around the world have raised interest in newly enforced or increased tariffs and their effects on global supply chains. For firms sourcing globally, tariff introductions or increases significantly affect importing costs, which ultimately affect product costs. Such tariff changes may incentivize firms to adjust their supply base to mitigate these cost increases, thus altering the structure and complexity of firms' supply bases. In this paper, we first characte...

Kraljic portfolio matrix has been widely used in purchasing as an effective diagnostic tool. Despite its popularity, the matrix has been criticized for subjective in categorizing commodities. In this paper, a quantitative model to position distribution network commodities with Kraljic portfolio matrix is proposed. Attributes for supply risk and profit impact are identified first. Questionnaire survey is then conducted to get the relative weight of every attribute and the performance score. To de...

Abstract This study investigates the evolution of the design, development and implementation of a strategic sourcing framework able to support decision-makers in formulating differentiated, rather than generic supplier base strategies. These strategies are in turn implemented through specific action plans, assuring the coherence and alignment between the different strategic hierarchical levels, beginning with business strategy, through category strategy to specific tactical sourcing levers. The ...
