The document outlines three models for user experience (UX) design: 1. Jesse James Garrett's model of the user experience consisting of skeleton, surface, structure, scope, strategy, concrete, and abstract. 2. A five-step process for UX design: understand, create, decide, prototype, and test. 3. The importance of arrangement in design as emphasized by quotes from Richard Saul Wurman, Eliel Saarinen, and Charles Eames about information environments, context, and quality connections.
