    There is no technology without uncertainty. A small amount of uncertainty can lead to a serious risk. Insurance has covered such a risk. In other words, technology and insurance have a strong complementary relationship. To strengthen the partnership between technology and insurance, I’d like to propose a system for promoting the development of autonomous driving cars and AI computer-aided detection. Specifically, Agence Qualité Construction, which is a part of the French housing guarantee system, will be applied to the fields of autonomous driving cars and AI computer-aided detection. It can be expected to contribute to technological innovation as well as to compensate for technological uncertainty.

    COVID-19 pandemic in Japan, the government recommends “cashless payment” to reduce contact opportunities.

    However, in previous research, there is concern about contact between people and objects in the payment operation of some payment methods, and the authors questioned whether the promotion of cashless payments alone is necessarily safe. In this paper, the authors have identified and clarified the payment operation process of the four cashless payment methods (credit card, debit card, electronic money, and QR code) by field survey. The results of the study revealed that there is a challenge in converting credit cards, which account for 90% of the cashless payment market share, to contactless. We also analyzed the trends in the market before and after COVID-19 by text mining of newspaper article data to identify their impact. After that, the authors discussed the feasibility of contactless and made recommendations for its solution. The recommendations are that the installation of contactless terminals in stores is costly, and that it is important to have a government initiative to promote it. The importance of promoting contactless credit cards to protect the elderly, who are more susceptible to COVID-19 infections, was also discussed.

    Digital Transformations (DX) promotion has become indispensable for business. However, DX promotion is not enough for small and medium-sized enterprises (SMEs). In addition, it is difficult for SMEs to solve the shortage of human resources, which is an issue for DX promotion. Therefore, in this study, we focused on the introduction of the ERP system, which is part of the DX promotion, and the lack of ability to define requirements, which is one of the issues of shortage of human resources. And, based on the agile philosophy, we proposed a model of agile software development method for SMEs. As the result of the study, it was found that the method is effective for some issues. In the future, we will improve the model based on this case and contribute to the DX promotion for SMEs.

    This paper is concerned with the relationship between business succession and corporate performance in family businesses. The hypotheses of this paper are as follows: “Companies run by successors who choose business succession from among other specific options perform better,” “Successors with good performance have proactive learning experiences before and after business succession,” and “Successors with good performance implement innovations after business succession.”

    The purpose of this paper is to examine the validity of these hypotheses using actual cases. The case studies will be based on interviews with the successors of family businesses that have experienced business succession, interviews with employees, and books written by the successors to confirm the following four points. The items to be checked were (1) the existence of options other than business succession, (2) the experience of proactive learning, (3) the existence of innovation, and (4) business performance (sales increase). We believe that the case studies, although limited, have indicated the importance of proactive business succession choices and learning by the successors.

    New business development approaches include an effectual and a causal approaches. An effectual approach was theorized as decision-making under unpredictable circumstances by Saras D. Sarasvathy. The effectual approach, against the opportunity-finding approach, is positioned as one of the effective approaches to create the future (product, firm, market) by starting with existing means (who you are, what you know and who you know) and forming partnerships with people/organizations and interracting with other people. The purpose of this paper is to clarify the successes and challenges for the effectual approach-based business development by referring to the case of HORIBA’s business development.

    The purpose of this study is to clarify how the environmental changes caused by the Covid-19 affected employee engagement, and to examine how remote work affects employee engagement and how it should be managed. In this study, social trends in working attitudes are confirmed from newspaper articles to understand the current situation, and a questionnaire survey of actual employees and interviews with employees are conducted to extract specific issues.

    The results of the survey indicate that telework not only has the effect of increasing employee engagement, but also has the effect of decreasing employee engagement by greatly affecting communication among workers. Therefore, it was concluded that although remote work is an effective tool for increasing employee engagement, it is necessary to introduce performance-based workplace culture and communication policies at the same time in order to take advantage of its effectiveness.

    This paper describes that a pragmatic way of knowledge management, which may ensure sustainable growth of companies, is to focus on talent development. The ideal knowledge management is one in which the process of knowledge sharing is embedded in daily operations. Specifically, it says that tacit knowledge is shared by fostering opportunities for knowledge sharing such as waigaya (Honda) etc. However, if knowledge is not viewed as “Knowledge”, but as “Knowing”, its effectiveness is questionable. The suggestion, that fosters a process or place for sharing knowledge will result in an integration of knowledge, is based on the premise that those who receive the knowledge are willing to absorb it. Fostering the will of recipient to absorb the knowledge, which is being spoken and shared, is what makes this premise true and makes possible the creation, sharing, and utilization of knowledge.

    By integrating P. F. Drucker's observation that “communication is done by the receiver” into the SECI model developed by I. Nonaka, we present a practical model for knowledge management. In other words, we hypothesize that the foundation of knowledge management is to develop the recipients of knowledge and to enlarge their capacity. BASF's focus on employee development is examined as an effective and pragmatic approach.

    The purpose of this paper is to focus on “NEMAWASHI”, which is one of the characteristics of group-oriented decision making that is often seen in Japanese companies, and to clarify how “NEMAWASHI” affects the innovation process. As a result of an interview with a key man who is using “NEMAWASHI” at a large Japanese company A, “NEMAWASHI” is three routes to realize “Creative justification of resource mobilization” (hereinafter abbreviated as “Creative justification”) required for successful innovation. While contributing to each of these, it was clarified that it can induce traps associated with the “Creative justification” process and can also be a factor that hinders “Creative justification”.

    In addition, we newly found that “NEMAWASHI” has a learning effect of “NEMAWASHI” (improvement of the ability to search for appropriate counselors and key persons, and the ability to form human networks) and knowledge creation occurs in the process of “NEMAWASHI” as a function that was not discussed in “Creative justification”.

    This study examines how changes in service value can be visualized using an innovation architecture that encompasses service value creation. Based on the macro model of service value (co-)creation proposed earlier, we have developed a method to think about service value shift using a hierarchical architecture redefined by the impact of digitalization towards DX (digital transformation). The method is applied to cases in high-end accommodation services and smart networked RT (robot) / information services. These case studies not only show how service value is shifting in these businesses, but also explain trends in overall service value as influenced by modern digitalization and smartization. This framework provides a basis for effective strategic planning of service companies by simulating the routine of (co-)creating service value at the service value level through further generalization and abstraction of customer needs towards DX of business and reorganization of the service organization.

    This study defines efficiency of production as the profit per hour of production, taking the amount of material loss into account. An analytical evaluation method is developed in which a production line that produces more high-efficiency products (estimated from the production efficiency of each order and entropy value of each product) is given high evaluation.

    This paper, the second in a series of articles on global management strategies for SMEs, is titled "What is globalization?" and reports on the significance of globalization for Japanese SMEs, business globalization (creation of new markets), and examples of global business initiatives.

    The significance of globalization for Japanese SMEs is that global management is required to create new businesses that can be accepted worldwide in order to maintain competitiveness and sustainable growth.

    Global business requires three components: the ability to recognize the current situation, the ability to develop a business concept, and human resources.

    The following is a summary of the seven processes that Japanese small and medium-sized enterprises (SMEs) must go through in order to conceptualize and develop new businesses when expanding overseas.

    Chapter 2 of Digital Education for Executives in Small- and Medium-Sized Enterprises series is titled “Learning to Read, Write and Use Personal Computers (PCs).” It goes back to the origins and talks about what has been changed in the workplace since we started using PCs instead of abacuses.

    The Japanese manufacturing would rarely survive without top management perspective changes. With the status quo, there is a risk to lower the productivity more, and Japanese leadership should tackle to improve IT employees’ IT literacy. At this rate, we will be further behind in the global market, and be lagging behind foreign companies in the competition.
