Workshop 3.0 held at Design Factory Aveiro, marked a focal milestone in the co-design journey towards sustainable design innovation for Revigrés. Participants engaged in dynamic prototyping activities, leveraging interdisciplinary collaboration to explore solutions for energy challenges. Through structured decision-making methodologies and hands-on prototyping, participants navigated the complexities of the design process, fostering creativity, collaboration, and problem-solving. The outcomes showcased a diverse range of solutions addressing challenges related to smart solutions and kinetic tiles, highlighting the importance of interdisciplinary collaboration and design principles. Prototyping emerged as a gateway to innovation, enabling participants to transform abstract ideas into tangible solutions and iterate rapidly to refine their concepts. The workshop underscored the significance of prototyping in testing assumptions, gathering feedback, and designing for the user, ultimately driving the development of impactful solutions tailored to end-user and company needs. The session also underscored the critical role of facilitators in guiding participants through the design process, fostering a culture of experimentation and collaboration. Integration of the results with previous studies allows to establish a parallelism between the facilitator role and the importance of design leadership, particularly through the role of the Chief Design Officer, in guiding organizational change and fostering a culture of innovation. By embracing prototyping, interdisciplinary collaboration, and design leadership, companies can unlock new opportunities for innovation and create meaningful impact in the marketplace, fostering organizational growth.
