| Abstract | This chapter discusses how to understand the purpose of formative usability evaluation. We raise concerns about common ways of understanding usability evaluation, and propose a complementary view of usability evaluation as idea generation. Implications of this view for researchers and practitioners are discussed, and it is argued that seeing usability evaluation as idea generation may help move research in evaluation methods forward. In addition, we suggest practitioners some benefits of viewing their work as idea generation and some concrete techniques based on this view. |
