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?

Proof of Concept

Design Validation

Management By-in

Reduce Misinterpretations

Save Time and $$$

“We don’t have the time to prototype?”

“We can’t afford to prototype. We don’t have the budget.”

Guidelines for Prototyping

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)
