A design is a blueprint or specifications for the construction of an entire system or object, or the manifestation of that design in the form of a model, implement, machine or process, etc., or simply the resultant of that design. The verb to design normally expresses the procedure of developing a design by means of some systematic process of illustration, simulation or experimentation. It is also used in engineering, for instance to mean the production of certain specific measurements and designs by means of precise computer programs, and also describes the processes of designing and constructing an entire structure, machine or gadget. In the study of design, the term refers to the methodology of graphic design, which studies the effects of stylized visual representations on real objects or their qualities.
Designing is based upon a number of underlying principles. The foremost of these is the principle of identifying the end users or the users of a product and designing accordingly. Another important principle is that of identifying and documenting the designing process, and the product according to its various specifications, as well as the end-user or consumer, and documenting these in an agreed manner.
The other design principles are grounded in social theories, such as those concerning the nature of communication, politics, economics, technology and society. The communication principle refers to the designers’ ability to satisfy the users’ needs and fulfill their wants. Another essential principle of designing is that designers must respect the users’ rights and meet their requests, and be responsive to them in a timely fashion.
