In this environment, companies is necessary to predict the trend of the market and consumer, the input timing and the development trend of new technology the trend of the market and consumer. Against this background, the authors analyze "Analysis of a Technology System Evolution by Focusing on a Technology Maturity". This analysis is based on theory of the evolution theory of the technical system of Altshuller. In this paper, we focus on WOM(Word of Mouth) and analyze" Analysis of a Technology System Evolution by Focusing on WOM ". This analysis is based on "Innovator theory". Analysis of WOM, we intended to understand the establishment of disruptive innovation, the trend of the market and consumer, the input timing and the development trend of new technology the trend of the market and consumer. We found WOM is affecting the technology system evolution that tends to increase the number of WOM.
