They design new bikes by choosing a new gear shift, a new saddle and a new color. But the consumer doesn't care about that. The consumer has specific needs, like bringing children to school.

If you watched companies such as Sony and Samsung grow, they focused first on features and then on industrial design, which made their products look and feel better.

Effective problem solving in design requires a balance of strategy and spontaneity, intelligence and creativity.
