Design is thinking made visible.

to design means forcing ourselves to unlearn what we believe we already know, patiently to take apart the mechanisms behind our reflexes and to acknowledge the mystery and stupefying complexity of everyday gestures like switching off a light of turning on a tap

We have always thought about design as being so much more than just the way something looks. It's the whole thing: the way something works on so many different levels. Ultimately, of course, design defines so much of our experience.

Design is one of the few disciplines that is a science as well as an art. Effective, meaningful design requires intellectual, rational rigor along with the ability to elicit emotions and beliefs. Thus, designers must balance both the logic and lyricism of humanity every time they design something, a task that requires a singularly mysterious skill.

Definition of design = Everyone designs who devise courses of action aimed at changing existing situations into preferred ones. The intellectual activity that produces material artifacts is no different fundamentally from the one that prescribes remedies for a sick patient or the one that devises a new sales plan for a company or a social welfare policy for a state.

Design is really a special case of problem solving. One wants to bring about a desired state of affairs. Occasionally one wants to remedy some fault but more usually one wants to bring about something new. For that reason design is more open ended than problem solving. It requires more creativity. It is not so much a matter of linking up a clearly defined objective with a clearly defined starting position (as in problem solving) but more a matter of starting out from a general position in the direction of a general objective

In most people's vocabularies, design means veneer. It's interior decorating. It's the fabric of the curtains and the sofa. But to me, nothing could be further from the meaning of design. Design is the fundamental soul of a man-made creation that ends up expressing itself in successive outer layers of the product or service

[Design is] an expression of purpose. It may, if it is good enough, later be judged as art.

Design is not just what it looks like and feels like. Design is how it works.

One could describe Design as a plan for arranging elements to accomplish a particular purpose.

Participation is empowering and design is empowered by it.

As a noun, design is the named (although sometimes unnamable) structure or behavior of a system whose presence resolves or contributes to the resolution of a force or forces on that system. A design thus represents one point in a potential decision space. A design may be singular (representing a leaf decision) or it may be collective (representing a set of other decisions).

Design is the conscious imposition of meaningful order.

Interest. ...a design to be great must have great interest. ...the most potent of all ways to impart interest is to endow the design with beauty of form, and... the one which makes the strongest appeal to human interest and admiration is physical beauty in human shape.
