Oh I understand. What I skipped explicitly writing there is, if he writes an abstraction, and defends it well then give him 10 points, if he can't defend, give him 5 points.

The fundamental point is, who can best figure out the requirements of the customer, and write code which makes most sense with least amount of 'future problems'.
