What is good design ?

The flow of creating something seems to follow the sequence- a thought to idea to tangibles. Tangibles can be something of value that one can feel or sense. From an idea to tangibles means various intermediate steps. The clarity on how to come up with these steps and laying it out on a media to see the manifestation of the idea is design. So, what is a good design? A good design is one in which the degree of closeness between the idea and its manifestation (tangible) is as close as possible.

On the other hand if the closeness between design and its manifestation is lacking then no amount of analysis and parameter tuning can markedly improve the value of the tangible. Which also means that there are fundamental contradictions designed into the manifestation. The ability to preemptively address and resolves design issues is an area of great importance.
