When first getting started working with youth on how to do design, I will show this video from ABC Nightline concerning the Silicon Valley design firm IDEO. It provides a summary of the design process starting with observation and synthesis through brainstorming and prototyping. It places a heavy emphasis on understanding the user or consumer, as well as the need to use prototyping early in the design process to identify shortcomings in the design and opportunities for improvement. The episode originally aired in 1999 and is available from a secondary source on YouTube.
