Co-Creating a Framework to Integrate Sustainable Design into Product Development Practice

Abstract

There is a growing recognition of the need to incorporate sustainability considerations early-on in the product development (PD) process (PDP). As part of a case study at an engineering consultancy firm, this paper identifies considerations that influence the integration of sustainable design practices into real-world PD practices. This is informed by the first author becoming embedded in the firm as an intern, and closely observing the PD workflow across various projects, conducting interviews and group discussions with a wide range of practitioners, and iteratively designing and testing various potential interventions. From the literature and observations, we find that designers and engineers often struggle to identify and apply the right sustainable design methods and tools (SDMTs) to tackle the environmental impacts associated with their products. Through a human-centered design process, we co-created a reusable, modular framework of practices that aids the selection of relevant strategies, based on the environmental hotspots, stage of the PD process, and the client’s sustainability priorities. Our prominent findings highlight the importance of: (a) co-creation in enhancing receptivity and retention, (b) the use of LCA iteratively to inform design decisions throughout PD, and (c) sharing case studies of successful application of the framework to promote sustainable design among employees and clients, alongside several other takeaways. The paper further presents insights related to the framework’s real-world application and impacts in the firm, based on results of longitudinal engagement with the firm.
