A design charette is a work- shop-style technique that provides a collaborative space that allows for this creation and cross- pollination of design ideas to occur. designers and non-designers--including project stakeholders, engineers, and users--can participate in a design charette. It can be used to explore ideas about opportunities of a large-scale design challenge, or generate possibilities regarding a very specific interface (where it is more commonly referred to as parallel prototyping). 2 The method is inspired by the process of biological natural selection and genetic algorithms, 3 which seeks to test and select the strongest qualities as the basis for the next generation. This process, when applied over several generations, results in a population (or in the case of a design charette, a design solution) that is optimized for success, given its various requirements. When planning a design charette, select a physical space that will inspire creativity and the flow of ideas. There should be a public space for participants to come together and discuss the range of ideas, and work spaces for individuals or groups to generate design ideas. At each work space, pro- vide tools to spur creativity: paper templates, pencils, erasers, color markers. The sessions should 1. The national Charrette Institute suggests that the term "charrette" originates from the École des Beaux-Arts in Paris. In the nineteenth century, it was not unusual for student architects to continue working furiously on the illustrations for their design presentations, even while riding in the school cart (en charrette) through the streets of Paris en route to submit the projects to their professors. Hence, the term was adapted into the current design-related usage to reflect its rapid pace. 2. McGrew, John F.
