A METHOD FOR COMPARING CONCEPTS WITH RESPECT TO SUSTAINABILITY AND OTHER VALUES

The audience for this research is fellow researchers and others helping product developers to start including sustainability when they are selecting product concepts.The aims of the research were to understand the needs of product developers integrating sustainability into concept selection and what might be done to help them.The research approach was to iterate between the three studies of design research methodology. The first study focused on understanding the challenges that product developers face when integrating sustainability into concept selection. The aim of the second study was to identify potential support to help product developers to deal with the challenges. And the third study was to try out the potential support to see if it actually helps product developers address the challenges they face. These studies were executed through reviewing literature and exploring two cases.The results led to a focus on supporting the decision-making process and supporting analysing with respect to social sustainability. Selecting concepts is a complex decision made under challenging conditions. Bringing in the complex, new and unfamiliar aspects of sustainability can make good decision-making even more challenging. When integrating sustainability, two particular barriers to good concept selection decision-making are errors due to illusory correlation and confirmation bias.Despite the challenges, how good you are at making decisions matters. And a good decision-making process drives good decisions. This is especially relevant when bringing in complex and unfamiliar aspects, such as sustainability. A likely candidate for helping product developers achieve a good decision-making process when integrating sustainability is active, value-focused decision-support. In other words, structuring the process into bite-sized steps and using particular techniques to avoid bias. At each step, decision-makers’ focus is anchored by the things that stakeholders value as important. Further research is required to investigate the details of how to employ these process-support approaches in the particular context of integrating sustainability into concept selection decision-making.In addition to a process, complicated selection decisions demand analysis. Support for analysing concepts with respect to social sustainability was identified as a gap. We explored a potential approach that might contribute to this analysis, but found that it was not useful for the particular decision in hand. This opened up some interesting questions for further research.
