2. About Me

3. 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. (http://en.wikipedia.org/wiki/Software_prototyping)

10. Save Time and $$$ “We don’t have the time to prototype?” “We can’t afford to prototype. We don’t have the budget.”

14. Guidelines for Prototyping

15. Short Timeframe

16. Build only what you need

17. Don’t be afraid to throw it out!

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

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

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

25. Medium Fidelity

26. Tools

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