Great design is not just a solution, it is the elimination of the problem.
Onur Cobanli explains:
Good design is a silent advertiser; it promotes the product without the need of a person shouting it is good; it shouts I am good already. Good design creates word of mouth advertising, it makes your product reach new markets and buyers without active involvement, when advertised, good design benefits most from it, as the message is augmented, multiplied and scaled up. Good design must advertise, promote and sell itself.
