About Me

What is a prototype? …incomplete versions of the software program being developed. A prototype typically implements only a small subset of the features of the eventual program, and the implementation may be completely different from that of the eventual product. (

Why prototype?

Short Timeframe

Build only what you need

Don’t be afraid to throw it out!

Types of Prototyping  Low Fidelity  Medium Fidelity  High Fidelity

Low Fidelity Prototyping  Quick to develop  Allows for explorations of ideas  Can be more difficult to conduct user studies  Zero coding!

Medium Fidelity Prototyping  More “real” user experience  Longer design time  Longer development time  Some level of programming  “Golden Path” / Slideshow

Medium Fidelity

Tools

High Fidelity Prototyping  Closer to reality  Greater design requirements  More development time  Can serve as a reference platform for other groups (Engineering, QA, Marketing)
