Disciplines for Designing PSS Actor Network

This paper presents disciplines for designing actor network of Product-Service Systems by visualizing state changes in design process and indicating tasks for state transitions. While IT vendors co-design new services with their clients, sporadic requirements and constraints may leave target users and business partners unsettled in the conceptual IT service system. IT vendors design a hypothetic service system and check it continuously through ad hoc workshops. They gradually identify such actors from possible groups of people, though this design procedure is still improvisational. A set of states and tasks is described indicating what PSS designers need to do next with possible actors, instilling correct disciplines for establishing relationships between them.
