Can we measure quality in design and do we need to?

The new usability agenda is driving empirical and experimental studies into a growing range of quality criteria such as engagement, user experience, and aesthetics. Some see this as a positive move to theorise about the nature of good design qualities, and to objectively test such hypotheses on the new usability theme. However, others (e.g. [1], [2]) have argued for interpretation-based inquiry into user engagement and experience on the grounds that such phenomena can only be understood by investigations into contexts of use which defy quantitative approaches. Many in the design community would agree with them and go further to argue that quality in design is a matter of creativity and can not be measured or theorised per se; instead, research should focus on understanding and improving the process of design. This panel will debate the tensions between these positions and explore possible common ground between them as a contribution towards the research agenda that is being debated in the DIS conference series.
