Ideation is core to the innovation process, and has been the subject of study across a range of fields, from psychology to engineering. However, despite substantial progress in outcome-based descriptions of idea generation, research has often resulted in more questions than answers. For example, open questions remain with respect to the differences...

There is a critical gap in understanding how meso-scale team processes i.e. interactions between individuals in a team, develop in design teams and specifically how they dynamically balance design/managerial effort. We treat this deficit by contrasting two in-depth cases using work sampling data. We identify a number of contributions. First, we des...

Understanding team diversity has become essential for modern-day organisations. This study explores the impact of knowledge diversity in design teams through computational simulations.

Facial aging is the most visible manifestation of aging. People desire to look younger than others of the same chronological age. Hence, perceived age is often used as a visible marker of aging, while biological age, often estimated by methylation markers, is used as an objective measure of age. Multiple epigenetics-based clocks have been developed...

Recently, the design and digitalisation approaches have become increasingly utilised in the legal context, typically under the names of legal design and legal tech. One of their goals is to help legal practitioners be more efficient and to provide better quality and more comprehensive legal services. Also, given that both movements rely heavily on...

Studies revealed that, while collaborating, humans tend to synchronise on multiple levels (e.g., neurocognitive or physiological). Inter-brain synchrony has been linked to improved problem-solving, decision-making, and creativity. Nevertheless, studies on synchrony in design teams started to emerge only recently. This study contributes to this stre...

All of these topics have been studied for some time, but only fairly recently has the study of networks in gene...

Design understanding and needed level of the accompanying spatial skills that enable it depend on information input provided by a visual representation of a design solution. During product development, designers use models to visually represent a design solution. These visual representations can be mediated by various technologies (for example, an...

The conventional prescriptive and descriptive models of design typically decompose the overall design process into elementary processes, such as analysis, synthesis, and evaluation. This study revisits some of the assumptions established by these models and investigates whether they can also be applied for modelling of problem-solution co-evolution...
