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

FAIL EARLY
(Cost of failure vs. project time curve)
8
FAIL OFTEN
(Risk vs. iteration curve)

PROTOTYPE ROUGH
(Coulter Leys “PlanB”)

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

PROTOTYPING TIPS
CANNIBALIZE
BE MINDFUL OF RESOURCES
ALWAYS BRING PROTOS

PROTOTYPE EVERYTHING
(Moon mission)
Golden Rules of Prototyping
14
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
