よりよい成果を得るためのワイガヤ理論

抄録

“Y-gaya”, which is a habit that engineers thoroughly discuss for long period of time, has been seen as a prominent mechanism to realize synthesis of design leading to actualization of brand new product. Though its effectiveness has been discussed empirically and given philosophical explanations, there has never been any theoretical explanation or systematized methodologies. Former paper attempted to explain “Y-gaya” based on general design theory. However, it could not refer to “Yokkyu”, which expresses what the product desired to be for users and society. As “Yokkyu”is a base for discussions and development of brand new product, theoretical explanation is essential for establishment of sound theoretical foundation of “Y-gaya”. This paper attempts to understand how “Yokkyu” is fermented in “Y-gaya”. As a result, by extending general design theory, fermentation of “Yokkyu” was theoretically explained. In the end, this paper discusses future prospects for systematization of “Y-gaya”.
