"Servitization" 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. Namely, the designers have to have a holistic view and consider value for each stakeholder. This paper proposes 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, a "service modeling method" to represent a service structure as a system composed of multiple stakeholders and a "service simulation method" to observe temporal changes of the each stakeholder's values are proposed. Further, a collaborative service design process to design a service that has high value for various stakeholders is proposed.
