It is difficult for a company to develop all the technologies in product development (PD) by itself in recent years, so the introduction of outside technologies is important. However, there is little quantitative research on this topic. This study proposes the effective information for evaluating and selecting PD alternatives introducing outside technologies. First, we clarify that the previous model proposed by Kusaka is also applicable to the problem, including strategic factors. Then we show the optimal solution by Branch and Bound method. Finally, we analyze the effect of outside technologies by “technology introduction index”, which means the ratio of the outside technology performance to the total performance at the optimal solution, and consider the effects of the cost and time constraints, and the concurrent degree on the index. The results of numerical analyses show that the degree of outside technology introduction is decided by the relation of the three factors. Therefore, the cost and time constraints, and the concurrent degree play important roles in PD introducing outside technologies.

There has been increasing interest in the field of technology management to promote efficient utilization of technology within an organization. We have investigated the effect of organizational factors that influence the acquisition of customer need, knowledge utilization or knowledge creation from a survey conducted at an IT-related firm. The analysis showed the importance of reciprocity, limited effect of IT-driven knowledge database and so on. And we also confirmed the stickiness of customer need, local use of knowledge and employees’ technology-orientation by the influence of environment. From these findings, we mentioned some points to keep in mind to discuss technology management.

One of the most important issues on the technology management in Japanese manufacturer is establishing methodologies for efficient cooperation between product design and manufacturing, thereby realizing competitive product development with high performance, high quality, low cost and short lead-time simultaneously. In this paper, efficient information transfers and flexible activities between two sections are discussed by analyzing actual successful activities in Japanese manufacturers. Then, as management tools, unit and chain models of the cooperation are proposed to analyze key factors for success of cooperation.

In this paper, the diffusion of 3G mobile is analyzed, focusing on the technology strategies of NTT DoCoMo and KDDI and the technology adoption by users. KDDI, a latecomer with a smaller customer base, has been much more successful in attracting customers to its 3G services than DoCoMo, a first mover and a market giant. This paper seeks to explore the reasons behind KDDFs success and the key factors affecting 3G mobile diffusion. Of special importance are factors such as the different corporate and technology strategies of the operators, especially regarding backward compatibility and standards and the technology adoption by users. Data has been obtained by conducting a set of interviews with key people connected to the mobile sector in Japan and a survey of mobile phone users. Subscriber and company statistics, brochures have also been analyzed. We conclude that success in gaining 3G customers depends, to some extent, on technology strategies related to backward compatibility, choices of standards and timing of standards changes.

The NPO-Driven Decentralized Research System is proposed as a new industry-academia-government cooperative research system to promote large-scale and long-term research. RoboCup as the first actual case was managed by the author with the trustees.

Six main organization properties of this system, “vision-driven” organization, autonomous and decentralized nature, facilitation of collaboration with other sectors, openness, competitiveness and selectiveness and ease of start-up can manage ten factors that negatively affect long term government-driven R&D projects in Japan. Nine concrete management measures were picked out and proved effective to promote research activity in RoboCup.
