Commentary Figure 1. Different types of value change. (Credit: Ilse Oosterlaken.) aspect of it is respecified, leading to different norms and design requirements. If we consider values at a higher level of abstraction, we could also consider the aforementioned example of car design as a respecification of the value " safety, " with bystander and occupant safety becoming part of how safety is specified. The kinds of value change we have outlined are important for the design and development of technologies. Taking value change into account will improve technology's normative desirability and will increase the likelihood that relevant societal stakeholders take up technologies. In the following 28 section, we discuss methods that engineers and designers can use to deal with value change. Dealing with value change in design and engineering The possibility of value change has implications for the design for values approaches that focus on values during the design phase of new technologies. We suggest three ways in which value change can be accounted for in the design of new technology: 1) improving the anticipation of possible future value change; 2) expanding design for values approaches IEEE Technology and Society Magazine
