Understanding user value creation is an important part of service design; however, creating value for users is rarely an easy task. Going beyond likes and dislikes into the motivations behind the use requires specific approaches and methods. The present paper, based on an online food store case study, shows how value creation can be predicted and what kind of determinants affect service design. We used a questionnaire, rapid prototypes, and a co-design workshop to retrieve user data and to develop the concepts. The goal of the study was to form design drivers for a functional prototype that would be evaluated in a real world context. The main determinants affecting the service design in our case were Design base, Concept/Product, Domain/Context, Users, Company, and Resources. Our findings suggest that the user value elements can be grasped using cost-efficient methods.
