Slides from a talk made by KeeKim Heng of Google Switzerland on a RusCHI seminar #22, Moscow, Russia

1. The Principles of Rapid
Prototyping for Design
KeeKim Heng Google Web Developer

2. Who am I?
I am a Web Developer working on Google Maps.
I work in the UX team building rapid prototypes.

3. What is the goal of this talk?
Learn how prototyping can improve how we design products.
Learn how prototyping can improve how we communicate our
designs to engineers.

4. Who is involved?
Stakeholders
Researchers
Designers
Web developers
Engineers

5. How do we design without prototyping?
Produce product requirements
Design life cycle

6. What is the product design life cycle?

7. What problems are there?
Engineering the design can take a long time.
Slow feedback loop for each design iteration.
Communication problems between design and engineering.

8. What is rapid prototyping?
Implementing partial product functionality as fast as possible.
Not worrying about any production issues.
It's like magic - smoke and mirrors.

9. What is purpose of rapid prototyping?
Exploring designs
Validating designs
Testing designs
Communicating designs

10. How can we design with prototyping?
Produce product requirements.
Distinguish between two life cycles:
Full product design life cycle.
Rapid product design life cycle.
The rapid life cycle is a step inside the full life cycle.

11. What is the full product life cycle?

12. Why is this good?
No engineering in the rapid product design life cycle.
Rapid feedback loop.
Better communication of design.
Better communication of technical constraints.
The result:
Faster design process with better products

13. Can we see an example?

14. What kinds of prototypes are there?
Paper/Mock walk-through prototypes
Powerpoint prototypes
Flash prototypes
Rapid web prototypes

15. Thanks!
