Research paper : Acquisition of skills on the shop-floor (N. Matsuki)−85−Synthesiology - English edition Vol.3 No.1 (2010) studied and discussed in the beginning when the project was proposed.Answer (Norio Matsuki)As you indicated, they should have been studied beforehand. However, the actual situation of skills at the companies is complex, and there were many things that we would have never known until we started the project. I think this research could have resulted in a tool that could be utilized effectively on site even with the initial assumptions only, but we believe better results were obtained by changing the scenario according to the situation.3 Clarity of the componentsQuestion (Kanji Ueda)For the derived model, is the content of “as derived model, theoretical formula… experimental formula… data mining…” related to Fig. 7 (Expert skills in casting and its visualization) or does it refer to the hypothesis or the obviosity?Answer (Norio Matsuki)These are the hypotheses of this research. If possible, we would like to continue our research of skills and continue investigating these hypotheses.4 Future of expert skilled workerQuestion (Kazuo Igarashi)You say: as a result, it is necessary to have sufficient engineering knowledge to be a successor of an expert skilled worker in decision-making and action. You also say: the future image of the expert skilled worker is an advanced engineer on site. Certainly, this conclusion is in one direction, and while it may be applicable to large corporations, I don’t think this is feasible in middle and small businesses that were the subject of this research, due to the resource recruiting problem. Is it appropriate to draw such definitive conclusions in this paper?Answer (Norio Matsuki)The manufacturing industry faces severe global competition regardless of the size of the company. While this may sound like an extreme conclusion, I think even the small and minute companies can no longer afford to employ unskilled laborers in a traditional manner, and must move in this direction.
