Enabling the Integration of Sustainable Design Methodological Frameworks and Computational Life Cycle Assessment Tools into Product Development Practice

Environmental sustainability has gained critical importance in product development (PD) due to increased regulation, market competition, and consumer awareness, leading companies to set ambitious climate targets . To meet these goals, PD practitioners (engineers and designers) are often left to adapt their practices to reduce the impacts of the products they manufacture. Literature review and interviews with practitioners show that they highly valued using quantitative life cycle assessment (LCA) results to inform decision making. LCA is a technique to measure the environmental impacts across various stages of a product life cycle. Existing LCA software tools, however, are designed for dedicated experts to use at the end of PD using detailed product information. This creates the “ecodesign paradox”, a tension between opportunity for change in the early-stages of PD and availability of data in later stages to make reliable decisions. Further, my research identified that novice users of LCA face additional barriers including: cumbersome user interfaces, unfamiliar terminology, and complicated information visualization. To address these challenges, I developed a tool called EcoSketch for use during early-stage PD by novice users. Practitioners, however, also struggle with translating environmental impact information into actionable design decisions. Hence, I co-created methodological frameworks of sustainable design strategies with industry partners: Synapse Product Development Inc. and Stanley Black and Decker Inc. Despite contextual differences, a key commonality was that practitioners at both firms sought “structured” and “data-driven\u27\u27 processes for sustainable design. Through multiple, extended internships, I also identified important drivers and barriers to sustainable design integration. Overall, my research demonstrates that co-creation improves receptivity, long-term adoption, and produces tangible improvements to sustainable outcomes in practice. In summary, my research pursues two key pathways to enable sustainable design integration: Developing human-centered life cycle assessment (LCA) tools that are designed for decision-making during the early stages of PD. Creating methodological frameworks to support the application of appropriate sustainable design strategies in PD practice. This thesis elaborates on my proposed coupling of robust frameworks with human-centered LCA tools, which I argue together comprise a transformative solution for industry professionals to effectively integrate sustainability considerations in their product development practices

Co-Creating a Framework to Integrate Sustainable Design into Product Development Practice: Case Study at an Engineering Consultancy Firm

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.Circular Product Desig
