Blockchain Implementation in Supply Chains: Analysis Based on Literature Reviews and Case Studies
摘要
The integration of Blockchain technology (BCT) into supply chains and logistics operations has emerged as a promising field to address the challenges inherent to efficiency, transparency and security. The literature about benefits and barriers in blockchain implementation has been growing in the last years. However, it remains unclear to managers at which stage of BCT implementation projects these challenges arise. Therefore, based on the qualitative analysis of case studies and literature reviews, this work provides to professionals and researchers the association of the main barriers to be overcome in the BCT implementation phases. The PRISMA research methodology is used to define the portfolio of 161 articles from the Scopus database. Initially, content analysis of the articles show that private and hybrid Blockchain models are most recommended for supply chains, due to their secure integrity and processing speed. Also, twelve technologies were associated with BCT and QRcode, RFID, IoT and smart contracts are the most cited. However, technologies such as Metaverse, Digital Twins and Machine Learning were also found. Regarding the four technology implementation phases and the thirteen barriers found, the pre-adoption and adoption BCT phases are associated with a greater number of barriers in blockchain implementations. It demonstrates the importance of clearly presenting the technology to the target audience and have the managers and employees engagement during BCT implementation process.
