Mental models-what people really have in their heads and what guides their use of things. The mappings between the concepts and the user experience the product is designed to support. Enables designers to straighten out their thinking before they start laying out their widgets. Provides a working strategy and a framework of general concepts and their interrelations. Idea-select, combine, adapt and enhance various ideas (raw material) into workable solutions (proposed improvements) What to do with all those ideas and how do you choose. With users or with peers; e. g. prototypes (remember these are just ideas) Set early on and check regularly (check the principles again) Compare/evaluate against your goal, problem, and requirement statements.
