Approaches To Managing Global Sourcing Risk
(Emerald Group Publishing Ltd, 2011-03-15) Christopher, Martin; Mena, Carlos; Khan, Omera; Yurt, Oznur
Purpose - Global sourcing can bring many benefits to organisations, but it can also expose them to a number of risks. The purpose of this study is to understand how managers assess global sourcing risks across the entire supply chain and what actions they take to mitigate those risks. Design/methodology/approach - A multiple case study approach was used, involving 15 cases in seven different industries. Each case consisted of interviews with manager; directly involved in the global sourcing decision, supported by documentary evidence. A cross-case analysis was conducted to analyse patterns across different industries. Findings - The study revealed that most companies do not have a structured supply chain risk management and mitigation system. Nevertheless they do use a number of informal approaches to cope with risk. The paper proposes that a multidisciplinary approach is required when dealing with global sourcing risks. It presents a classification of risks covering four categories: supply risk, process and control risks, environmental and sustainability risks, and demand risks. Originality/value - The paper addresses a research gap concerning managers' approaches to assessing and mitigating supply chain risk in a global context. In this context, this study proposes a new categorisation for global sourcing risks and offers a characterisation of global sourcing risk mitigation strategies applicable to different industries.

The Causes of Food Waste in the Supplier-Retailer Interface: Evidences From the Uk and Spain
(Elsevier, 2011-04) Mena, Carlos; Adenso-Diaz, B.; Yurt, Oznur
Food and drink waste is a significant problem for economic, environmental and food security reasons. Government efforts have focused on diverting waste away from landfill through regulation, taxation and public awareness. However, efforts to understand why waste occurs have been limited, particularly in the interface between retailers and suppliers. This research aims to address this problem by identifying the main root causes of waste in the supplier-retailer interface. The research is exploratory in nature as there is a paucity of studies focusing on food waste across the supply chain. Data were collected through 43 interviews with managers in food manufacturing, wholesaling and retailing in two countries: the UK (24) and Spain (19). Data from the interviews and supplementary documentation were analyzed using causal maps. This approach helped to identify the main root causes of waste which were categorized into three groups: (1) mega-trends in the marketplace, (2) natural causes related to the products and processes, and (3) management root causes on which practitioners have a direct impact. The paper discusses the root causes of food waste and good practices identified from the interviews. Differences between the UK and Spain are discussed, presenting potential learning opportunities for practitioners in these countries and highlighting opportunities for further research.
