Behavioural design has emerged as an important domain of design research and practice. However, there is a need to better distinguish behavioural design and subsequently map its unique features and challenges. In answer to this need, this work examines the evolving role of behaviour in design and contrasts this with eleven in-depth behavioural design cases. This has resulted in our identification of behavioural design as a new paradigm of design, with a number of unique characteristics. Based on this, we propose a model of behavioural design. Furthermore, we identify three critical barriers to behavioural design in practice, and suggest ten mitigating enablers. Together these findings provide implications for further development of theory, practice, and education in behavioural design. [ABSTRACT FROM AUTHOR]

Behavioural design has emerged as a critical new area of research and practice. However, despite the development of extensive lists of possible problem features and suggested solution principles there is little guidance on how these should be connected. Therefore, in this work we systematically examine interactions between major problem features and solution principles, based on an analysis of 218 behavioural design interventions drawn from 139 cases across design domains and foci. This forms the basis for a number of contributions. First, we bring together behavioural and designerly perspectives on problem characterisation via two proposed problem features: change demand and behavioural constraint, related in a two-by-two framework. Second, we synthesised recommendations from across domains and foci to operationalise a list of 23 solution principles relevant to designers. Third, we link these insights in a proposed Behavioural Problem/Solution (BPS) matrix. Further, we identify a number of potential systemic challenges in the reporting and evidencing of behavioural design interventions. Together, these insights substantially extend both theory and practice surrounding problem-solution mapping in behavioural design, and form a foundation for further theory development and synthesis in this area.

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. The design of products for the BOP is an important ingredient of the poverty reduction approach that combines business development with poverty alleviation. However, the current understanding of the design for the BOP is limited. This study, using a protocol analysis, compared design processes for the BOP and TOP markets. The results indicate the difference between the design processes for these markets in terms of the design strategy employed by the designers (i.e. problem driven, solution driven strategy), their requirements handling behaviour, and their information behaviour.
