| user research analysis design evaluation: usability design iteration design specification |
Design A navigation model is created, often by using a metaphor relevant to the users. This navigation model must match the user's mental model-the way they think and work in their environment when accomplishing a task. A screen-flow diagram, wireframes, and lo-fidelity prototypes are then generated. These prototypes are cheap to create and generate lots of good feedback in a usability study. |
