This document contains information from Hazel White's HCI 3 class on January 24, 2011. It summarizes several design models and methods, including action research, Sun Sigma framework, Nigel Cross' four stage design process, Vijay Kumar's innovation planning model, and RIP + MIX. RIP + MIX is introduced as a design method for idea generation that involves "ripping" attributes from one artifact and "mixing" them with attributes of another artifact to generate new product or service ideas. The document provides examples of applying RIP + MIX and assigns students to choose two artifacts, describe their attributes, and use RIP + MIX to create a new artifact.
