Although recognized as a key to the design process, prototyping often falls victim to budget cuts, deadlines, or lack of access to sophisticated tools. This can lead to sloppy and ineffective prototypes or the abandonment of them altogether. Rather than lose this important step, people are turning to Microsoft Excel (R) to create effective, simple, and inexpensive prototypes. Conveniently, the software is available to nearly everyone, and most are proficient in its basic functionality. Effective Prototyping with Excel offers how-to guidance on how everyone can use basic Excel skills to create prototypes - ranging from narrative wire frames to hi-fidelity prototypes. A wide array of software design problems and business demands are solved via practical step-by-step examples and illustrations.
