A Method for Understanding Customer Demands based on Extended Eco-VA

Abstract

A sustainable society requires that products be environmentally friendly and conform to the market needs. According to this background, a tool named Extended Eco-Value Analysis has been developed by improving existing Eco-Value Analysis that allows product developers to analyze the functions of a product from economic costs, customers’ importance, and environmental impacts. However, a result obtained from the application of this Extended Eco-VA is open to discussion. Therefore, this paper proposes a new method to obtain more accurate customer requirements. Furthermore, the authors improve the product evaluation criterion that is adopted in Eco-VA by considering the above method.
