Avoiding the pitfalls of Cooperative Purchasing through control and coordination: insights from a humanitarian context
International Journal of Procurement Management, 2015Co-Authors: Heidi Herlin, Ala PazirandehAbstract:In this paper, barriers to the success of Cooperative Purchasing are discussed from an inter-organisational coordination perspective and a framework for successful Cooperative Purchasing is introduced. Potential benefits such as economies of scale, better transparency and more efficient information exchange have generated high interest for Cooperative Purchasing as a supply chain strategy. However, literature notes several instances of such cooperation not having the expected outcomes. We aimed to further the understanding of the coordination barriers to the success of Cooperative Purchasing. By studying an exemplary situation of an unsuccessful Cooperative Purchasing, the attractiveness and inherent complexity of a Cooperative Purchasing process is highlighted. This study draws on and adds to the existing literature on Cooperative Purchasing by discussing coordination related barriers to Cooperative Purchasing and provides managerial insights into what to consider when engaging in the Cooperative Purchasing strategy to avoid the pitfalls.

Unfruitful Cooperative Purchasing: A case of humanitarian Purchasing power
Journal of Humanitarian Logistics and Supply Chain Management, 2014Co-Authors: Ala Pazirandeh, Heidi HerlinAbstract:Purpose – The purpose of this paper is to understand the impact of Cooperative Purchasing on buyers’ Purchasing power. Purchasing in the humanitarian sector has traditionally been characterized by a low level of coordination due to inter-agency competition for funding, diverging mandates and other organizational differences. Relationships with commercial suppliers have also remained arm's-length and often dormant due to high levels of uncertainty and strict public procurement rules and regulations. However, recent pushes for increased efficiency and effectiveness are driving humanitarian agencies toward Cooperative Purchasing – a Purchasing strategy that is claimed to be highly beneficial for members of the Purchasing consortium not least for its ability to increase buyers’ Purchasing power. In reality, the effectiveness of the strategy in increasing Purchasing power is unclear. Design/methodology/approach – The authors study a single case of several humanitarian organizations aiming to increase their lev...

Horizontal Cooperative Purchasing
2007Co-Authors: Fredo SchotanusAbstract:Purchasing in groups is a concept that is becoming increasingly popular in both the private and public sector. Often, the advantages such as lower purchase pricese, learning from each other, and reduced transaction costs outweigh set-up and management costs and drawbacks such as disclosure of sensitive information and the fear of free-riding group members. The concept is not always successful though. Still, it has received relatively little attention in management research. In this thesis, we study the establishment and management of Purchasing groups. We define Purchasing groups as organizations in which horizontal Cooperative Purchasing takes place. We define horizontal Cooperative Purchasing as the operational, tactical, and/or strategic cooperation between two or more organizations in one or more steps of the Purchasing process by pooling and/or sharing their Purchasing volumes, information, and/or resources.

Cooperative Purchasing Micro-Evolutions: A Longitudinal International Study
2007Co-Authors: Fredo Schotanus, Elmer Bakker, Helen Lisbeth Walker, Michael EssigAbstract:This paper deals with the evolution of relatively young Purchasing groups. Although previous research focussed on macro-evolutionary phases of Purchasing groups, no attention has yet been paid to the intra-phase developments, the so-called ‘micro-evolutions’. Insight into micro-evolutions is crucial to better understand how Purchasing groups (can) develop over time. We conducted three in-depth case studies in different countries and identified five dimensions of micro-evolutions: member relationships, objectives, activities, organisation, and resources. For each dimension, we provide an overview of micro-evolutions to guide Purchasing groups in developing the dimension. We conclude that the dimension ‘activities’ is very important and that Purchasing groups do not have to develop the dimensions simultaneously.

Developing a typology of organisational forms of Cooperative Purchasing
Journal of Purchasing and Supply Management, 2007Co-Authors: Fredo Schotanus, Jan TelgenAbstract:This paper develops a typology for Purchasing groups. In the typology, five main forms of Cooperative Purchasing are distinguished based on seven main dimensions. The forms are positioned in a matrix according to two distinguishing dimensions. These two dimensions are the ‘influence by all members on the group activities’ and the ‘number of different group activities’. Underlying the two-dimensional matrix, there are five other dimensions that do not distinguish all forms from each other, but further detail the forms of Cooperative Purchasing. The typology can serve as a guideline for Purchasing groups when a suitable organisational form needs to be chosen. In a suitable form, the dimensions of a group fit together. For all groups, it is recommended to find this best fit. This is something in which the typology may help. The paper concludes by emphasising the importance of clearly defining and positioning studied forms, because different forms imply different research models and have different advantages, disadvantages, and critical success factors.

Co-operative Purchasing in the Public Sector
2007Co-Authors: Helen Walker, Fredo Schotanus, Michael Essig, Timo KivistöAbstract:Cooperative Purchasing is not new – either in scientific research or in practical application. Historically, forms of cooperation and consortia in Purchasing were first discussed by Mitchell (1927) and Gushee and Boffey (1928). According to Sanders and Knapp (1979), the first Ph.D. thesis on Cooperative sourcing was written in 1969 at the University of Denver. According to Encarta (1999), Cooperatives as we know them go back to the cooperation by the labour movement in the United Kingdom in the eighteenth century.

Implications of a classification of forms of Cooperative Purchasing
2005Co-Authors: Fredo Schotanus, Jan TelgenAbstract:Our main objective is to classify different forms of Cooperative Purchasing, i.e. Purchasing groups. Based on a literature review, empirical findings, and new institutional economics we employ a classification: the highway matrix. In this matrix we distinguish five forms of Cooperative Purchasing according to the ‘influence by all members on the group activities’ and the ‘number of different group activities’. The classification can serve as a guideline for (potential) Purchasing groups when a suitable form needs to be chosen. Managerial implications of a classification include an emphasis on differences in organisational structure and critical factors. Research implications include an emphasis on the importance of using a classification, as different forms of Cooperative Purchasing imply different models and mechanisms.

Cooperative Purchasing of logistics services among manufacturing companies based on semantic web and multi agent system
Practical Applications of Agents and Multi-Agent Systems, 2010Co-Authors: Arkadiusz Kawa, Pawel Pawlewski, Paulina Golinska, Marcin HajdulAbstract:The common access to the broadband Internet allows small and medium enterprises (SME) simpler participation in various supply chains [3]. However the main problem still is lack of consistency between processes which are undertaken by various supply chain participants. The aim of this paper is to propose the concept of broader cooperation between manufacturing companies based on semantic web and multi-agent system. The background of this paper refers to previous experiences of the authors by implementation of the CORELOG project. It promotes cooperation in logistics services among manufacturing companies located in the Bologna metropolitan area in order to increase companies’ competitiveness as well as environmental sustainability through the rationalization of the logistics processes. The application of semantic web and multi-agent system in the above mentioned project allows the efficient automatic data collection about logistics services providers and their resources, as presented in the Internet.
