I'm just a common person, but I'll offer you my crude understanding.

Good products vs Great products


Good Product is expressed in prose,
Great product in poetry.
Good products succeed on key metrics,
Great products make the metrics irrelevant.
Good products satiate a need,
Great products create new ones.
Good products solve problems,
Great products solve the problem space.
Good products look good,
Great products define good looks.
