EXAMINING THE USER EXPERIENCE OF LIFE CYCLE ASSESSMENT TOOLS AND THEIR ABILITY TO CATER TO ECODESIGN IN EARLY-STAGE PRODUCT DEVELOPMENT PRACTICE

Abstract

AbstractWith the topic of sustainability steadily gaining importance and public awareness, there is growing consensus about the need to incorporate environmental considerations in early stage product development (PD). This makes it imperative for PD practitioners to have access to methods and tools, including life cycle assessment (LCA), that support sustainability integration. This paper evaluates existing LCA tools on their ability to cater to the early-stage PD context, by having users apply the tools in practice and exploring their experiences. We find that the challenges to applying LCA in this context emanate primarily from the shortcomings of the tools themselves. Our evaluation metrics for tool critique are derived from a thematic analysis of user interviews we conducted, refined according to information and interaction design principles from human-computer interaction (HCI). This unique approach helps triangulate insights from users with literature, to produce design recommendations for the development of novel LCA tools tailored to the early PD context.
