ABSTRACT
In this paper we argue that there is a scarcity of methods which support critical, systemic, long-term thinking in current design practice, technology development and deployment. To address this need we introduce value scenarios, an extension of scenario-based design which can support envisioning the systemic effects of new technologies. We identify and describe five key elements of value scenarios; stakeholders, pervasiveness, time, systemic effects, and value implications. We provide two examples of value scenarios, which draw from our current work on urban simulation and human-robotic interaction . We conclude with suggestions for how value scenarios might be used by others.

When a new technology comes along?for example, personal robots, virtual worlds, or human cloning?the potential impact can be enormous. And yet, how is the designer of the technology supposed to factor all of those implications into the design of the technology__?__ Tough question. One way is for the designer to attempt to anticipate, as well as possible, what those implications may be. But, again, how can that be done__?__ This paper offers one possibility: value scenarios. Value scenarios are systematically constructed narratives for exploring the implications of a technology from the perspective of the stakeholders, the pervasiveness of the technology, the time frame of the effects, and the extent to which the effects are systemic. The paper provides two scenarios to illustrate how value scenarios can be used. The paper has merit to the extent that people who design new technologies really should think ahead about the potential impacts of those technologies. The notion of value scenarios does provide a little structure to that process. At the same time, value scenarios as described would require great creativity and insight on the part of the designer, and a designer with this level of creativity and insight might well be able to anticipate impacts without having to use a technique such as this. A larger problem is the fact that technologies evolve over time, and frequently find their way into unintended uses, for better or for worse. It is unlikely that the designers of a significant technology will be able to anticipate the evolution and unintended uses, much less the impacts of the unintended uses. So, while the paper is certainly well intended, it is not at all that clear how much value it really contributes to the discussion. Online Computing Reviews Service
