Materials matter. Designers use biological materials to solve trade-off problems (e.g., strong and light-weighted chair). Consumers buy transparent products. When students join the Master of Product Design and Development program in the Segal Design Institute, Northwestern University, they should take Materials Selection course in the beginning before learning about accounting, negotiation, strategy, decision making, and market research.
In the DDP, Seoul Korea, I met a section dedicated for materials. I saw the same section when I visited TCDC, Thailand Creativity and Design Center. I expect the material section enable general public to develop the knowledge about and the taste of different materials so that they think more creatively.
