Research paper : Two types of lead users in a model for the transfer of technology into households (Y. Kubo et al.)−193−Synthesiology - English edition Vol.2 No.3 (2009) this is an important point. However, there are descriptions such as “women as independent individuals” and “women who are in charge of cooking in homes,” but I don’t think the importance of the role of “women” is clear in the data and analysis of this paper.Answer (Yuka Kubo)One of the reasons the logical and sensible lead users contribute to the diffusion of technology from their positions is because the general users do not understand the content of the technology. I pointed out the contribution of women lead users because there are many technologies whose users are women who may not understand the technology. However, the roles of logical and sensible lead users who contributed to the introduction of IH to households can be played by men in non-IH cases. I removed the references that are limited to “women,” and shall continue this research to demonstrate that the model applies to cases of other technologies.4 Examples of other productsQuestion and comment (Motoyuki Akamatsu)I think it will be helpful to readers if there are comparisons or discussion with other products. For example, pressure cooker may be used as another example for cooking utensils.Answer (Yuka Kubo)Unlike a microwave oven and a rice cooker that can be used by a user who has no skill, recipe, or tool, the user cannot benefit from an IH product alone. Similarly, for products that require supplementary components such as user’s skill, recipe, and tools, various lead users are expected to contribute in diffusion, as indicated in this paper. For example, pressure cookers and waterless cookers were developed a long time ago, but information on cooking methods and recipes that optimize their functions are being transmitted by cookery researchers to this day. Recently, their users are increasing because there is a rising interest in reduced-oil cooking, and I think this is being accomplished through the contribution of lead users. I added the example of pressure cookers and waterless cookers in the discussion, and shall continue investigation of other case studies.5 Perspective of innovationQuestion and comment (Koh Naito)On “IH innovation,” in positioning it as an innovation, please describe which social value IH created when the technology appeared. I imagine that the appearance of the new cooking method affected the diffusion of IH because IH provided some new value to the user and it was not merely a technological replacement of gas.Answer (Yuka Kubo)The purpose of the generation and diffusion of the IH cooking system was to diffuse the value of “cooking that couldn’t be done before” to society, as they were discovered when “used” by logical lead users. However, it was found that people who were not interested in cooking before or those who were simply interested in design were motivated to engage in cooking, powered by the intuitive idea of sensible lead users who contributed to the diffusion. Also, the social value of the IH cooking system is diverse including safety and environmental concerns. I added these to chapter 7.
