A method for sustainable product development based on a modular system of guiding questions

In this paper, we present a method for sustainable product development (MSPD) with the aim of integrating social and ecological aspects of sustainability with a strategic business perspective in product development. The method applies backcasting from basic principles for sustainability, which allows a strategic approach, and it includes a modular system of guiding questions that are derived by considering these principles and the product life cycle. Initial testing in Swedish companies indicates that the suggested MSPD promotes a ‘bird's eye’ perspective and encourages and aids development of products that support society's transformation towards sustainability. Furthermore, it is concluded that the modular system provides flexibility and user-friendliness.
