This study investigates the “Internet of things” (IoT) and “Circular Economy” (CE) relationship in the current scientific literature focused on case studies or use cases on manufacturing context. To the best of our knowledge, this study is the first to map the science centered on “case studies” with respect to the “IoT” and “CE” connection, contributing to fill the gap of the subject that is already relevant to the scientific community and practitioners. The research methodology consists of developing a bibliometric study, employing PRISMA process, whose data is obtained from the Web of Science database. The VOSviewer was the computer program selected for the bibliometric analysis. The Web of Science (WoS) analysis tool supports VOSviewer. The papers were analyzed according to network analysis principles. The qualitative content analysis complements these results. The results show the high-frequency keywords and topics associated with the theme “IoT and CE”; the most cited papers; the intellectual structure of “IoT and CE”; the new emerging themes in scientific research; and social networks among the researchers. The paper’s contribution is the results of the bibliometric analysis and a better understanding of the relationship of “IoT” and “CE” by the “case studies” addressed in the empirical investigations.

Goal: The path to implement Digital Transformation (DT) in modern industries is far from clear, particularly in Brazil. From the point of view of operations management, authors developed a Conceptual Framework (CF) to support DT implementation in Discrete Manufacturing Industries (DMI). The CF applies knowledge management, hybrid project management (HPM) and Sociotechnical values to implement DT, using New Product Development (NPD) as a ground. The work aims to depict the HPM approach of this CF. Design / Methodology / Approach: this is a qualitative research based on a systematic literature review carried out over a period of five years. It was performed in the Web of Science database, applying PRISMA flowchart, to evaluate which project management models, addressed in the literature, are more suitable for DT implementation projects in light of sociotechnical and innovation-shared-values approach. Results: A Hybrid “Stage-Gate – Agile - Design Thinking” project management model to support DT implementation in DMI. This is a preliminary proposal that can be explored in future empirical research. Limitations of the investigation: Some quality papers may have been left out due to the research methodology. Practical implications: The CF can be applied by professionals to support Digital Transformation while incorporating sociotechnical values and reducing the excessive technological bias in NPD projects. Originality/Value: The authors propose a new Digital Transformation (DT) approach, named Sociotechnical Digital Transformation (SDT) and an HPM to support DT in light of a Sociotechnical approach.

As climate change is at the top of the world’s agenda, the armed forces and other defense actors must give a signal that they are environmentally responsible. In this regard, the defense industry should be one of the first actors to devise new strategies and actions aimed at reducing the environmental footprint. This article focuses on the measures being taken by the defense industry and the armed forces, and on how technology, the circular economy (CE) and Lean principles can contribute to a better environment. A qualitative multimethod research model was used, covering more than one research method, such as a systematic literature review and a case study research. Although the literature highlights that the defense sector in Europe is far from being a green actor, a transition to the CE was identified. In that regard, the European Union (EU) defense industry has been a key player in CE R strategies, such as: repurpose, remanufacture, repair, reuse, reduce and rethink. The contribution of new technologies has empowered military equipment to acquire enhanced characteristics, such as material resistance, while EU technology centers have been instrumental in a green transition. Additionally, more comprehensive research is needed in order to allow generalization of the results.
