The impact of supply disruptions from unplanned events can cause goods shortage, limited responsiveness and high opportunity cost thus compromising development aid programmes' achievement targets. These situations force humanitarian aid agencies to develop new strategies for effectively managing their supplies. The purpose of this paper is to illustrate the foundation of humanitarian supply chain resilience through the development of an adapted Kraljic portfolio model.

Action research was used to adapt and validate the Kraljic portfolio model to the development aid context. The research team worked with a humanitarian aid agency in developing criterions and used Analytical Hierarchical Process (AHP) in weighting those key criterions.

The adapted portfolio model was able to evaluate purchases done by the aid agency by incorporating different perspectives related to the strategic importance of purchase and supply vulnerability. In particular, development aid programmes require large supplies annually. Better classification offers improved visualisation of purchases, leading to a more precise adoption of mitigation strategies and policies to minimise supply disruption risks.

Adapting the Kraljic portfolio model is a stepping-stone to building humanitarian supply chain resilience. The proposed humanitarian supply chain resilience framework is based on the foundation that current humanitarian supply chain needs to be re-engineered. In order to re-engineer, the supply base strategy must first be revisited.

Many aid agencies do not have a holistic view on their purchases and commonly apply a transactional classification of purchases that only considers the consumption values. Purchasing strategies mostly focus on cost minimisation, whereas risk mitigations have been disregarded. The proposed portfolio model overcomes these drawbacks. Societal impact may be limited but development aid agencies will be able to offer more reliable aid delivery as part of their mandate.

The proposed portfolio model is among the first tool to guide humanitarian aid agencies to develop procurement strategies to alleviate supply disruptions and increase development aid programmes resilience.

Procurement professionals widely use purchasing portfolio models to tailor purchasing strategies to different product groups’ needs. However, the application of these approaches in hospitals and the impact of a pandemic shock remain largely unknown. This paper aims to assess hospital purchasers’ procurement strategies during the COVID-19 pandemic, the effects of factor-market rivalry (FMR) on strategies and the effectiveness of purchasing portfolio categorizations in this situation.

This qualitative study of hospital purchasing in the Netherlands is supported by secondary data from official government publications. Semi-structured interviews were conducted with 13 hospital purchasers at large hospitals. An interpretative approach is used to analyze the interviews and present the results.

The findings reveal that product scarcity forces purchasers to treat them as (temporary) bottleneck items at the hospital level. The strategies adopted largely aligned with expected behavior based on Kraljic’s commodity management model. Adding the FMR perspective to the model helped to further cluster crisis strategies into meaningful categories. Besides inventory management, increasing supply, reducing demand and increasing resource coordination were the other common strategies. An important finding is that purchasers and governments serve as gatekeepers in channeling FMR, thereby reducing potential harmful competition between and within hospitals.

The devastating experience of the COVID-19 pandemic is unveiling critical weaknesses of public health-care provision in times of crisis. This study assesses the strategies hospital purchasers apply to counteract shortages in the supply chain. The findings of this study emphasize the importance of gatekeepers in times of crisis and present strategies purchasers can take to assure the supply of resources.

No research has been conducted on purchasing portfolio models and FMR implications for hospitals during pandemics. Therefore, the authors offer several insights: increasing the supply risk creates temporary bottleneck strategies, letting purchasers adopt a short-term perspective and emphasizing the high mobility of commodities in the Kraljic commodity matrix. Additionally, despite more collaboration uncovered in other studies regarding COVID-19, strong rivalry arose at the beginning of the pandemic, leading to increased competition and less collaboration. Given such increased FMR, procurement managers and governments become important gatekeepers to balance resource allocation during pandemics both within and between hospitals.

The purpose of this article is to develop a new model called strategy segmentation methodology (SSM) by combining the Kraljic portfolio matrix (KPM) and the supplier relationship model (SRM) so that the buyer company can effectively conduct its relations with its suppliers.

The importance weights of the criteria defining the dimensions of each model are calculated with the single-valued neutrosophic analytical hierarchy process (SVN-AHP) method. Subsequently, the derived importance weights are employed in the single-valued neutrosophic technique for order preference by similarity to ideal solution (SVN-TOPSIS) method to obtain the scores of the suppliers and their supplied items. In order to illustrate the feasibility of the proposed methodology, a case study in the machinery industry is performed with the related comparative analysis.

The implementation of SSM enables to formulate various strategies to manage suppliers taking into account the items they procure, their capabilities and performance and the supplier–buyer relationship strength. Based on the proposed strategies, it is concluded that the firm in the case study should terminate its relationship with six of its suppliers.

Although KPM has become the basis of purchasing strategies for various businesses, it neglects the characteristics of suppliers and the buyer–supplier relationship. In this study, KPM is integrated with the SRM approach presented by Olsen and Ellram (1997) to overcome these disadvantages of KPM. The novel integration of the two approaches enables the realization of a robust and reliable supplier classification model.

The purpose of this paper is to reduce impact on profit and supply risk, for strategic part by defining appropriate purchasing strategies using Kraljic portfolio model (KPM) approach.

A five-step approach of KPM is used to identify strategic parts. The attributes affecting impact on profit and supply risk are then identified. A structured questionnaire is prepared for each attribute. Likert scale having weights from 1 to 5 is used to select method of measurement for each response. The overall score of attributes for dimensions “supply risk” and “impact on profit” interpret the position of the part, i.e., “strategic part,” “leverage part,” “bottleneck part” or “non-critical part” in the Kraljic matrix. The part having highest impact on profit and supply risk is to be considered as strategic part for defining the purchasing strategies.

This paper outlines a practical solution to the problem of designing/defining purchasing strategies for development of supplier. Impact on profit is reduced by cost reduction and quality improvement whereas supply risk reduced by improving delivery time and suppliers profile.

The proposed methodology is applied to a boiler industry to identify the strategic parts and focus on strategic suppliers, which are fewer in number but having larger impact on profit and supply risk. The “Body” part of ball valve assembly of the boiler is considered for the study. However, it can be extended for selecting and evaluating of suppliers strategy for other parts of the boiler. Not only boiler industry sector but also other companies also benefit from the results of this study by implementing the purchasing strategies as formulated in the KPM.

The Kraljic matrix has been largely used in many different industries like automobile, manufacturing, construction, oil and gas, etc., as an efficient tool for developing differentiated purchasing strategies. However, its application on parts procured by boiler industry is unknown, as well as the lack of systematical approach on criteria prioritization which is one of the key issues of the methodology. This work explores the output usefulness and its applicability on ball valve assembly projects.

The purpose of this paper is to develop a Humanitarian Purchasing Matrix to guide purchasing strategies for relief items in humanitarian operations.

The research synthesizes the structures of a Purchasing Portfolio Model and the characteristics of purchasing in humanitarian operations, validating them with academics and practitioners to develop a Humanitarian Purchasing Matrix. Then, based on the Analytic Hierarchy Process to classify the relief items in the matrix, an illustrative example is used as an empirical test for the proposed Humanitarian Purchasing Matrix.

The academic literature on purchasing in general and purchasing in humanitarian operations share some similarities in terms of “Importance of Purchasing” and “Complexity of Supply Market” dimensions. Moreover, the analysis of such criteria supports the definition of purchasing strategies for different relief items in humanitarian operations.

The Humanitarian Purchasing Matrix can be considered a tool/guide for professionals of humanitarian organizations in the adoption of purchasing strategies for the different relief items purchased for humanitarian operations.

Considering a scenario of a constant increase in the variety of relief items, the high purchasing volume and the pressure to more efficient relief operations, the research discusses the intersectionality of business purchasing models and the purchasing characteristics of humanitarian operations. Moreover, the research deliveries a tool/guide to the adoption of purchasing strategies that are composed of criteria observed in the literature and suggested by both humanitarian logistic academics and practitioners.

Buyer companies’ engagement with suppliers varies according to their specific business needs. Prior models of supplier classification are based on the dimensions like product specification or criticality of purchase. As the supply chains are embracing collaboration among partners to respond to the dynamic market conditions, it is prudent to study the changes adopted by buyer companies for supplier classification. The paper aims to discuss these issues.

This is an exploratory research for identifying the criteria used for supplier classification based on the interviews of practitioners from buyer multinational manufacturing companies operating in India. The content analysis of the subjective responses led to the identification of distinctive criteria.

Although, many of the practitioners were unaware of the model per se, they labelled their suppliers as per the types stated in the Kraljic model. They mentioned twenty six criteria for supplier classification; five of which do not have any reference in the extant literature. The degree of presence of these criteria provides a multi-criteria framework for supplier classification that has been further extended based on prior models.

The exploratory nature of the study, its confinement to Indian milieu and small sample size could limit the generality and exhaustiveness of the findings.

The framework and its extension can be used by practitioners in assessing and classifying their suppliers for strengthening supply chain collaboration.

This research unveils five new criteria used by buyer companies for supplier classification. The multi-criteria framework for supplier classification and its extension give new insights into the supplier characteristics significant for supply chain collaboration.

This paper is about customer relationships from the perspective of small suppliers. More precisely, this paper aims to examine the relational implications through a product portfolio model with the main participants of the buying center (buyer/business manager).

The study first uses an in-depth qualitative data analysis to explore how elements of small suppliers’ relationship with such large customer’s main actors are affected by the nature of the product (categorized between strategic, bottleneck and non-critical items). From the results, an empirical model is drawn of small suppliers’ relational strategies in a product-centered and buyer/business manager relationship typology. To analyze the results of the empirical model, a quantitative analysis is performed, using the fuzzy set qualitative comparative analysis approach.

This study contributes to deepen the supplier–customer relationship analysis, from a product-centered and customer dyadic perspective (buyer and customer business manager). The findings highlight three different small suppliers’ relationship strategy with a different level of involvement of the different participants of the buying center.

Few studies so far analyze vertical asymmetric relationships from a triadic perspective composed of the small supplier, the buyer and the business manager – hence, this study contributes to unveiling some of the relationship complexity within a triad of actors and how small suppliers can navigate through this complexity according to their product or service positioning.

The purpose of this paper is to present a research model and case illustrations that explore strategic outsourcing practices for sustainable competitive advantages in the Chinese context.

This study is based on in‐depth interviews of executives of three multi‐national firms (MNCs) from Switzerland, Korea and the USA that have been successfully operating in China for more than seven years.

This paper discusses how three MNC firms in China maintain clear and disciplined strategic outsourcing and achieve desired business outcomes. They race to the top by managing strategic insourcing for high risk and high profit items while outsourcing low risk and high profit leveraging items.

The paper presents a strategic outsourcing model and case studies of three multi‐national firms in China, which suggest both theoretical and managerial implications showing how to implement successful outsourcing practices in the global market.

The work presented in this article is part of an action research project carried out in collaboration between Bang & Olufsen (B&O) and the Center for Industrial Production (CIP) of Aalborg University. The aim of the project is to investigate how end‐manufacturers can source new technology via innovative NPD‐related supplier relationships. Whereas prior work on buyer‐supplier relationships is dominated by a product‐oriented view, the present research has adopted a resource‐based (competence) view to develop a framework to guide companies in developing and handling competence‐based relationships with technology suppliers. The framework suggests four different types of inter‐organisational competence development, two of which will be illustrated using empirical data obtained through two in‐depth case studies of innovative partnership projects between B&O and some of its sub‐suppliers.

The purpose of this paper is to develop a differentiated approach to the cost management system of total cost of ownership (TCO), a system based on cost data. Existing TCO‐related literature has investigated the tool from a focal buyer perspective but has consequently neglected to study TCO from an inter‐organisational perspective.

An explorative single case‐study approach is used, involving a large, industrial Danish manufacturing company. Interviews were conducted with relevant representatives from both the purchasing division and a range of the division's suppliers and observations made.

This paper indicates that a differentiated approach to TCO might be necessary, as suppliers might react negatively to the focal company presenting TCO data in negotiations. A matrix is proposed involving two dimensions: the nature of the relationship and the complexity of cost drivers.

This study involves a single case study and is therefore not capable of enumerating frequencies. Future research should test the applicability of the findings in other spatial contexts.

Industrial managers should be aware that a differentiated approach to TCO is capable of solving problems pertaining to the current TCO “one‐size‐fits‐all” approach.

This is the first paper, known to the authors, to investigate the TCO concept from an inter‐organisational perspective.
