"Sensitization" of non-service industry is attracted much attention as a business model to enhance the value of products. In general, various stakeholders are involved in a service offering structure. To realize a sustainable business, therefore, it is important to make a business situation where each stakeholder involved receives high values through the service provision. Authors have proposed a method to design a service that has high value for each stakeholder with an approach of "collaborative design," where multiple designers who have different backgrounds participate together. In this paper, the proposed design method is applied to the design of a service to enhance a value of agricultural product for realizing the local revitalization of a town in Japan. On the basis of the application results, effectiveness and remaining issue of the proposed method is discussed.
