Ev has developed a way of analyzing his ideas, based on seven criteria/questions:
- Tractability: How difficult will it be to launch a worthwhile version 1.0?
- Obviousness: Is it clear why people should use it?
- Deepness: How much value can you ultimately deliver?
- Wideness: How many people may ultimately use it?
- Discoverability: How will people learn about your product?
- Monetizability: How hard will it be to extract the money?
- Personally Compelling: Do you really want it to exist in the world?
Ev discusses each of his criteria at some length, and offers examples of how these criteria applied to several highly sucessful products, including his own. Read his full post.
