CHAPTER 7. Verify Prototype Assumptions and Requirements
Jonathan Arnowitz, Michael Arent and Nevin Berger
In Chapter 5
, Bill Buxton describes the importance of sketching for generating design ideas. Sketching is the beginning of a design funnel with many ideas at the start that get winnowed down to a smaller set of ideas as the product concept evolves. To understand the design issues that will affect the success of a product, you can use a variety of prototypes that include wire frames, storyboards, paper prototypes, interactive simulations, video prototypes, and coded prototypes. Each type of prototype allows you to examine different assumptions that you have about your product concept.
