0. Handout on Prototyping for d.school summer workshop September 2006
Based on Handout for ME377
Winter 2006

1. PROCESS
Iterate
Understand
Observe
Visualize
Build
Test

2. ENLIGHTENED TRIAL AND ERROR SUCCEEDS OVER THE PLANNING OF FLAWLESS INTELECT
(Evolution of the eye)

3. IDEO Sinus Surgery Device Cannibalized Rough & Ugly Prototype

4. IDEO Sinus Surgery Device Refined Prototype

5. Build Test ITERATION Insight Prototypes Ideation and experimentation
Understanding of execution risks gained
Serendipity is enabled
Build
Insight
Prototypes
New insights and learning feed into the development process
Options are eliminated
Ideas are clearly expressed
Communication is improved
Test
Failure happens
Risk is reduced
Assumptions are challenged
The unexpected is revealed
Non-market forces (politics) are removed from the equation

6. (Cost of failure vs. project time curve)
FAIL EARLY
(Cost of failure vs. project time curve)

7. (Risk vs. iteration curve)
FAIL OFTEN

9. (IDEO “surgical tool”)
PROTOTYPE RAPID

10. (Richard Feynman demonstrates how the Challenger O-ring failed)
PROTOTYPE RIGHT

11. CANNIBALIZE BE MINDFUL OF RESOURCES ALWAYS BRING PROTOS
PROTOTYPING TIPS
CANNIBALIZE BE MINDFUL OF RESOURCES ALWAYS BRING PROTOS

12. PROTOTYPE EVERYTHING
(Moon mission)

13. Golden Rules of Prototyping
1. One question, one prototype
2. Go far enough
3. Stop before it's perfect
4. Cannibalize as much as possible
5. Don't fall in love with your prototype
6. Always build and share more than one prototype
7. Create to provoke and persuade
