How Should We Define "Design"?

Gardi Amit writes an article for Fast Company that poses these questions:

1. Is there truly a “new design” phenomenon?
2. Is any idea, whether it’s an initiative for social progress or a clever way to market movies, enough to be declared a work of design?
3. Can a construct such as a “process,” “business plan” or a “system” be work of design?
4. Lastly, are these metaphysical constructs always design or is there a threshold of beauty, a rigorous process, or another quality standard that must be met for something to be considered a design? In other words, is a ‘business plan’ always a form of “new design” or does it have to involve some level of good, “old fashioned” design to be considered more than an ordinary business plan? And, if the latter, what are the requisite elements that would distinguish one from the other?
