You'll get an overview of how people are moving through the site. Rapid Prototyping Unlike the other techniques described here, rapid prototyping isn't an evaluation technique. However, it's used in tandem with user testing or contextual research as a way to test new ideas, and it's a crucial part of an iterative design process. A prototype may be a simple rendering on paper, either hand-drawn or created in a drawing application like Visio or Illustrator. Paper prototypes are usually a series of screens that demonstrate one particular path or task sequence.
Interactive prototypes create a working model of either the entire site or part of it.
The interactive prototype may range from a nongraphic, linked framework for user testing to a proposed design that can be refined and reused in the final product. Best Practices Prototypes should be used as part of an iterative testing process. They should be tested, modified on the basis of test findings, and then retested. Interactive prototypes should be designed so that some of the prototypes can be reused. Expected Results Find problems with the interface design and interaction and test solutions.
