Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
Product Design
Product design as a verb is to create a new product to be sold by a business to its customers. A very broad concept, it is essentially the efficient and effective generation and development of ideas through a process that leads to new products. Thus, it is a major aspect of new product development.
Design
As in poetry and music, even the unskilled ear may be offended by a mistake in measure, without discerning the cause, may not also a mistake in the harmony of dimensions unconsciously offend us in design?
