4. 1. What’s a Prototype?

5. What’s a Prototype?
“An approximation of a product (or system) or its
components, in some form, for a definite purpose
in its implementation”
Chua, Leong & Lim, Rapid Prototyping: Principles
and Applications
“A visualisation of the requirements”
Arnowitz
“A prototype is a representative model or simulation
of the final system. Unlike requirements documents
and wireframes, prototypes go further than show
and tell and actually let you experience the design.”
Todd Zaki Warfel, Prototyping: A Practitioner's Guide

6. What’s a Prototype?
Three Dimensions:
1. Scope (Distinct aspect → Entire Product/Service)
2. Form (Abstract → Tangible)
3. Fidelity (Rough → Exact)

7. 2. Value of Prototyping

17. Principles
1. Know your audience and your goals
2. Involve the users (participatory design)
3. Focus on flows, interactions & user scenarios
4. You can sketch (it's a prototype - fake it)
5. Use prototypes for usability tests - reduce risk
6. Prototype only what you need – then stop
