Item Open Access Blockchain adoption in food supply chains: a review and implementation framework(Taylor and Francis, 2021-06-18) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelBlockchain technology has received significant attention from the food industry; however, due to the scarcity of successful Blockchain projects and sector-specific studies, a step-by-step approach for implementing Blockchain in food supply chains (FSCs) is still missing. A systematic literature review of 69 high-quality, peer-reviewed articles is utilized to capture Blockchain adoption drivers and barriers, applications, and implementation stages within FSCs. Current Blockchain issues such as scalability, regulations, privacy, and incentivization are identified as future research opportunities. Following innovation adoption theory, a three-stage conceptual framework for Blockchain implementation in FSCs is developed. The proposed framework is novel and is expected to benefit food chain managers in establishing the suitability of Blockchain for their organization and/or wider supply network. Identified influential factors, case examples, and implementation stages are expected to guide practitioners in developing a roadmap for adopting Blockchain in the food industry.Item Open Access Blockchain implementation in the food supply chain: a systematic literature review(University of Warwick, 2020-06-30) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelThis study explores the literature on the implementation of Blockchain in Food Supply Chain Management (FSCM) and attempts to disseminate key insights along with potential directions for future research. A systematic and rigorous process of searching and scanning resulted in 53 peer-reviewed papers for the review. Findings from the selected papers include drivers and barriers to the adoption of the technology, current applications of Blockchain, and typical structure of the system in FSCM. Suggestions for future researches include empirical works to examine Blockchain implementation at supply chain level and influential factors to the implementation process.Item Open Access Blockchain technology for food supply chain: an investigation of the implementation process and impact on supply chain performance.(Cranfield University, 2023-03) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelThe food supply chain (FSC) plays a vital role in sustaining human life and achieving economic growth. Food and agricultural products are inherently perishable, sensitive to temperature, dependent on nature for production, and seasonal. As the result, businesses have to face specific and persistent challenges in monitoring food quality and safety, and reducing waste. Moreover, the globalization and complexity of the modern FSC can lead to pressing issues such as information asymmetry, low transparency, and food adulteration. Businesses and academics have explored Blockchain technology as a potential remedy for the hurdles of managing the FSC. While the technology has grown at an impressive pace, the knowledge regarding Blockchain adoption and its impact is yet fully explored. Therefore, there is a compelling need for researching the Blockchain phenomenon in the FSC setting, contributing to both literature and practice, and ultimately to better management of food products. To close the gap, this thesis particularly aims to investigate the adoption process of Blockchain and its impact on operational performance. Through a series of three studies, this thesis provided a literature review of the subject, developed an evidence-driven model for Blockchain integration, evaluated the relationships between important determinants to the Blockchain implementation stages, and specified the effects of adopting Blockchain on key performance metrics of the FSC. The key findings of this thesis are three-fold. First, the thesis provided an extensive and scientific systematic literature review about the current state of Blockchain adoption research in the area of food supply chain management. Specifically, the literature review synthesized four main themes from relevant literature, including the Blockchain adoption process, drivers and barriers to the adoption, and applications of Blockchain in food management. Second, the thesis constituted a holistic model of Blockchain implementation in the specific context of the FSC. Started with combining insights from the literature review and Innovation Adoption theoretical lenses to develop a conceptual model for iii Blockchain implementation in the FSC, the thesis then employed a mixed- methods approach to develop the conceptual model further. First, interviews were conducted to explore the process of adopting Blockchain in the FSC. Then, quantitative data was gathered by a survey to statistically assess the key relationships in the implementation model. The result is an evidence-based and feasible model of Blockchain adoption for organizations in the FSC. This model details Blockchain implementation activities and critical determinants of the process (implications from interviews findings), as well as analyses the most important determinants of each adoption stage (implications from the survey findings), all in the FSC setting. Third, this thesis evaluates the impact of a successful Blockchain adoption on the operational performances of an FSC. Using the System Dynamics modelling approach and simulations, the thesis illustrates holistically how Blockchain technology can affect key performance metrics, including inventory level, service level, lead time, and cost, at a supply chain level. Findings in this thesis subsequently make several key contributions to literature, practice, and policy. The thesis extended the current knowledge of the Blockchain phenomenon in the context of FSC, especially how to implement the technology and what impacts it can have on supply chain performance. Moreover, the thesis provided valid attempts at elaborating Innovation Adoption theories and models to better explain the particular context of Blockchain in the FSC and bringing System thinking and System Dynamics approach to examine supply chain phenomenon. The results of this thesis inform managers in the field about the approach to implementing Blockchain technologies, and what factors they need to understand for successful adoption. The System Dynamics models in this thesis further provide a useful tool for businesses to experiment and explore the impacts of the technology on their operations. Moreover, the findings in this thesis suggest several important implications for policymakers. Particularly, they highlight the important role of regulators in advocating for the industry-wide adoption of Blockchain, provide an in-depth understanding of Blockchain roadmap and impacts for promoting the technology among businesses, and suggest regulatory bodies direct more efforts into onboarding the lesser iv technologically capable entities in the FSC (farmers, SMEs, etc) to a Blockchain network.Item Open Access An empirical assessment of the determinants of blockchain implementation in the food industry(2022-07-13) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelItem Open Access Evidence-driven model for implementing Blockchain in food supply chains(Taylor & Francis, 2022-08-24) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelBlockchain technology has been identified as a possible solution to address critical challenges faced by the food sector. Building on the potential of Blockchain within Food Supply Chains (FSC), this study aims to develop an evidence-based implementation model for Blockchain in the food industry. Innovation Adoption and other prominent theories are integrated to first develop a conceptual framework, which is later validated following an analysis of the qualitative data. Fifteen semi-structured expert interviews are used to develop an evidence-driven, applied model for implementing Blockchain; providing detailed insights into typical stages, associated activities, and contextual determinants needed for successful integration. An empirically validated implementation model advances the extant academic literature and further provides a detailed roadmap for food practitioners, while initiating Blockchain projects with their firms and/or supply chains.Item Open Access Impact of blockchain implementation on food supply chain performance(European Operations Management Association: EurOMA, 2022-07-06) Vu, Nam; Ghadge, Abhijeet; Bourlakis, MichaelBlockchain has gained considerable interest in food supply chain (FSC). While literature has adequately explored the potentials of Blockchain to single process/company, there are limited studies attempting to examine the impact of Blockchain on the food supply chain network. Thus, this study attempts to model the FSC using System Dynamics (SD) approach to evaluate the impact of Blockchain on key supply chain performance metrics. SD models are built on the collected empirical data and relevant literature. The simulation results with illustrative parameters indicate that Blockchain has strong potentials to improve inventory level, lead time, service level and supply chain effectiveness.Item Open Access Implementing blockchain in the food supply chain: an empirical study(CLIT, 2021-09-10) Vu, Nam; Ghadge, Abhijeet; Bourlakis, Michael
