    Managing cyber risk in supply chains: a review and research agenda
    (Emerald, 2019-07-25) Ghadge, Abhijeet; Weiß, Maximillian; Caldwell, Nigel D.; Wilding, Richard D.
    Purpose: Despite growing research interest in cyber security, inter-firm based cyber risk studies are rare. Therefore, this study investigates cyber risk management in supply chain contexts. Methodology: Adapting a systematic literature review process, papers from interdisciplinary areas published between 1990 and 2017 were selected. Different typologies, developed for conducting descriptive and thematic analysis were established using data mining techniques to conduct a comprehensive, replicable and transparent review. Findings: The review identifies multiple future research directions for cyber security/resilience in supply chains. A conceptual model is developed, which indicates a strong link between IT, organisational and supply chain security systems. The human/behavioural elements within cyber security risk are found to be critical; however, behavioural risks have attracted less attention due to a perceived bias towards technical (data, application and network) risks. There is a need for raising risk awareness, standardised policies, collaborative strategies and empirical models for creating supply chain cyber-resilience. Research implications: Different type of cyber risks and their points of penetration, propagation levels, consequences and mitigation measures are identified. The conceptual model developed in this study drives an agenda for future research on supply chain cyber security/resilience. Practical implications: A multi-perspective, systematic study provides a holistic guide for practitioners in understanding cyber-physical systems. The cyber risk challenges and the mitigation strategies identified support supply chain managers in making informed decisions. Originality: This is the first systematic literature review on managing cyber risks in supply chains. The review defines supply chain cyber risk and develops a conceptual model for supply chain cyber security systems and an agenda for future studies.

    Service provider boundaries in competitive markets: the case of the logistics industry
    (Taylor and Francis, 2018-10-22) König, Christian; Caldwell, Nigel D.; Ghadge, Abhijeet
    The study empirically investigates service provider firms’ attempts to move to higher value added market segments in competitive and fragmented markets; using logistics services as a context. Novelty is added by taking the provider not the customer or outsourcing actor perspective, common to current third-party logistics perspectives. Data were collected in the form of semi-structured interviews with management at various provider firms. The interview guide was based on theoretical constructs regarding tangible and intangible capabilities (RBV) as well as constructs related to governance and integration (TCE). Unlike customer focused studies, this study is able to identify what distinguishes the rare successful boundary crossing attempts that lead to a more profitable market position. The key finding which contradicts studies based on the customer/outsourcing actor perspective, is that a switch from a highly commoditized market position to a higher margin position is only possible, if relationships and network capabilities are leveraged, regardless of the assets and physical resources available to the firm. The presentation of service boundaries as both dynamic and fluid and the use of RBV are contributions, building on existing theory, illustrating why providers of commoditized services cannot escape from low-margin, competitive market positions simply by acquiring tangible assets.
