    This study aims at exploring the relationships between the emotional intelligence of leaders and the intention to introduce IoT-based products (or product innovation) and the moderating role of different moderators on the above relationships. The paper uses the survey-based methodology and SEM analysis technique with sample collected in Vietnam. The findings show that there is the positive impact of emotional intelligence of leaders on the intention to introduce IoT-based products at firms and there is the moderating role of different moderators moderating the above relationships. Our study is among the first demonstrating the impact of leaders’ personal characteristics in driving IoT adoption and more broadly innovation at companies. The second theoretical contribution is that our research findings have introduced two new moderating variables for business research on the impact of personal traits of leaders on innovation (with the case of IoT-based products). The implications from this research are also presented.

    With the globalization and digitization of corporate activities in recent years, the efficiency of supply chain management and company-wide information flow has become urgent issues. Responding to these issues, Japanese companies have been implementing and utilizing enterprise systems to efficiently coordinate various activities related to value creation. This study aims to elucidate the actual status of the enterprise system implementation and operation, as well as the critical issues commonly encountered, based on an exploratory case study of five Japanese manufacturing companies. The contribution of this paper is to clarify the characteristics of the problems that arise when integrating existing IT systems, new IT systems, and manufacturing organizational capabilities from the perspective of IT system evolution and the dynamic process of corporate activities to overcome these problems. Another significant contribution is the presentation of a framework for a comprehensive analysis of the evolutionary process of the implementation and utilization of the enterprise systems.

    In recent complex product systems development, product design orientation is emphasized for the purpose of corporate brand building. The literature on the design-oriented product development is focused on that for consumer goods, and it may not be appropriate to apply the past findings to that for the complex product systems with a high degree of user involvement. This paper describes an actual case of design management in the development of rolling stock, which is a complex product system. It analyzes the characteristics of design management, especially noting how the users who place importance on regional brand building manage the outsourcing of design works. The analysis implies that, in order to promote the front-loading of development, the collaboration is effective, not between the two parties of users and designers, but between the three parties including specialist advisors in design.

    In the field of industrial and supply chain management, blockchain symbolizes a paradigm of autonomous decentralized system. In spite of increasing interests in it, there are few literatures which concretely explain how the blockchain works and how it brings about the change in business process and daily management of the enterprise as a new management system architecture. In about 10 years after the birth of blockchain, this paper highlights and explains representative examples in each of three development stages of blockchain. Through the review of literatures in various fields, the operating principle of Bitcoin, Ethereum and Hyperledger Fabric are analyzed. From the viewpoint of operations management, their features and effects on the current system are explained in detail and schematically. Moreover, on the consensus algorithms which are called the essence of blockchain, this paper introduces the one which is respectively suitable for public chain, private chain and consortium chain, which are the main frameworks of blockchain. It also explains application scenarios and examples in the context of business process and supply chain.
