This paper presents the development of a new interview tools to conduct interviews by incorporating physical tokens embedded with concepts related to product longevity. The objective is to augment the depth and quality of qualitative interview data in the field of longevity and sustainability studies.

Designing longer lasting smart products need a longevity understanding that is informed by both Sustainable ICT and design for sustainability. By conducting a literature review in both areas, we are able to identify longevity related concepts. We briefly outline these ideas in the two fields before discussing their relationships to reveal how they can contribute to one another. By nourishing the viewpoint from both sides, we broaden our understanding of longevity. We conclude our research by highlighting the gaps that (1) there is a need for applicable coping strategies for smart products, (2) a fair division of responsibilities between the multiple actors, and (3) the need for more interdisciplinary research to clarify longevity considerations.
