Digital marketing assignment

assignment, watch this short HBR video on new product idea prototyping and then address the pros and cons of doing what the presenter, Tom Hulme from IDEO, suggests in a segment he calls:

Launch your next idea before its ready

IDEO is one of the premier design new product design shops in the world.

Skip the focus group place your product or service in a real-world environment.
Test its appeal online to reach a larger market.
Launch a mock version to confirm if fills a need.

Again, this sounds like a somewhat radical idea for the time this video was released.  Think about this approach in a digital world —  discuss the pros and cons of doing as Tom suggests.  And, if you were an entrepreneur, is this an approach you would personally try?
