Towards sustainable product development – Insights from testing and evaluating a profile model for management of sustainability integration into design requirements

Product development and manufacturing continues to be a profound contributor to the socio-ecological problems and challenges we are facing in our world today. For products to contribute to sustainability requires not only that socio-ecological lifecycle impacts are considered in the initial stages of the product innovation process, but that they are maintained as integral product requirements. Although research offers a plethora of approaches, methods, and tools for sustainable product development, the implementation in industry remains low. The focus of this research is a less explored area of sustainable product development implementation, the management of needs identification and propagation of design requirements. The purpose is to: i) add to state of knowledge about current practices of sustainability integration into requirements, and ii) the academic discussion on implementation of sustainable design and product development. A self-assessment approach for sustainability integration into requirements is tested. The purpose of the approach is to support improvement of the requirements management process design, including activities and competencies, for engineering design. Four Swedish product development and manufacturing companies tested the approach, from which the results are used to evaluate usefulness, usability, and effect potential. The findings are discussed together with key characteristics for requirements and sustainability criteria, providing insights to ensure that socio-ecological considerations are both influencing the initial requirement specification, and maintained as decision parameters throughout the product development process. •Key areas of management of sustainability integration into product requirements are proposed.•Evaluates a self-assessment approach for sustainability integration into requirements.•Discusses implementation of sustainable product development approaches.•Examples from sustainability integration at four Swedish product development companies.
