Design is used both as a noun and a verb. The term is often tied to the various applied arts and engineering (See design disciplines below). As a verb, "to design" refers to the process of originating and developing a plan for a product, structure, system, or component with intention[1]. As a noun, "a design" is used for either the final (solution) plan (e.g. proposal, drawing, model, description) or the result of implementing that plan in the form of the final product of a design process[2]. This classification aside, in its broadest sense no other limitations exist and the final product can be anything from socks and jewellery to graphical user interfaces and charts. Even virtual concepts such as corporate identity and cultural traditions such as celebration of certain holidays[3] are sometimes designed. More recently, processes (in general) have also been treated as products of design, giving new meaning to the term "process design". The person designing is called a designer, which is also a term used for people who work professionally in one of the various design areas, usually also specifying which area is being dealt with (such as a fashion designer, concept designer or web designer). Designing often requires a designer to consider the aesthetic, functional, and many other aspects of an object or a process, which usually requires considerable research, thought, modeling, interactive adjustment, and re-design. Being defined so broadly, there is no universal language or unifying institution for designers of all disciplines. This allows for many differing philosophies and approaches toward the subject. However, serious study of design demands increased focus on the design process[4][5].
