When ‘Feeling Good’ is not Good Enough: Seven Key Opportunities for Emotional Granularity in Product Development

This paper reports a study that explored the usefulness of positive emotional granularity (PEG) in the product development process. PEG
reflects the ability to interpret and represent the experience of positive emotions with precision and specificity. Interviews were conducted
with twenty-five design professionals to understand their needs and expectations with respect to the value of PEG in product development
processes. Across all product development stages, sixteen PEG benefits were identified and grouped into seven key opportunities: getting
in-depth understanding of user emotions, determining the emotional impact of a product, dealing with organizational support, keeping
continuity of emotional intentions in communications, facilitating design creativity, strengthening emotional coherence and managing
emotions within a product development team. The findings indicate that the benefits of PEG are mainly associated with activities in
design conceptualization and evaluation, being less relevant in the embodiment phase. The article also reports on the different attitudes of
professionals with different roles in product development towards the relevance of PEG for their practices. The implications for research
into facilitating PEG and recommendations for developing design tools are discussed.
