Systematization of product life cycle technology utilizing the QFD method

The environmental QFD was developed to satisfy the requirements of new products by extracting technical assignments, but it is difficult to do systematization of technology assignments. For example, the technology assignment to satisfy one requirement is not only one by any means. There is a technology group that can contribute to one requirement in the same way, even if the technologies in one group come from a lot of different areas. Rearranging and systematization of technologies have been demanded traditionally, however, the approach to be settled systematically has not been suggested so far. This paper suggests a systematization technique related to product life cycle engineering utilizing the quantification type 4 and the environmental QFD. There are common tendencies about technical systematization. Therefore some systematization of technologies is possible. The superposition with importance and systematization gives us a suggestion about alternative technologies from the viewpoint of target achievement.
