Correlation between idea generation effort and resulting design solution success: An empirical study using RNEV as a new assessment technique

DS-Viz: a method for visualising design spaces

“…Despite these challenges, many attempts have been made to create design space visualisations. We briefly review here the most notable examples: (a) parallel coordinates plots (Fischer et al, 2014), (b) computationally-derived design spaces (Agrawal and McComb, 2023;Danhaive and Mueller, 2021), (c) set-based design spaces (Nickel et al, 2022) (d) genealogy trees (Bayırlı and Börekçi, 2022;Shah et al, 2003), and (e) conceptual design spaces (Gero and Milovanovic, 2022), which are illustrated in Figure 1.…”

“…Once the problem is defined and solutions are collected, the next step is to characterise the solutions. Different approaches are possible, from the traditional qualitative analysis that identifies the core functions of the solutions, relying on consensual assessment from expert judges (e.g., Bayırlı and Börekçi, (2022) and Shah et al, (2003)) to the use of design space schemas (Halskov and Lundqvist, 2021) that list relevant "aspects" and the available "options" across the set of solutions analysed.…”
