• Ideation and experimentation• Understanding of execution risks gained• Serendipity is enabled

• Ideas are clearly expressed• Communication is improved

• New insights and learning feed into the development process

• Options are eliminated

• Failure happens• Risk is reduced• Assumptions are challenged

Golden Rules of Prototyping

1. One question, one prototype

2 G f h2. 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 persuade7. Create to provoke and persuade
