Incentives

Collaboration - Prize requires that the task is achieved: if the 4x8' printing printer is not produced AND documented - the reward is not awarded. This forces people to collaborate - as the 6 month deadline is too short for anyone to do it on their own.
Encourage Collaboration - it is in the interest of the development leaders to publish and be transparent - as qaulity documentation is a requirement.
The Team is every participant, and not exclusive teams. There is no subgroup to keep information hidden - points are scored by publishing, collaborating, and educating.
Changing the World with Enterprise - to make this spread, enterprise documentation is required as part of success.
