A Designer is a person whose work uses the design process. This means that a designer could be everyone who will use drafts, sketches (or nowadays also conceptual models created inside virtual worlds like computer programs) to aid in the creation of a work, a product, an equipment of any scale.
Classically, the main areas of design were only Painting, Sculpture and
Architecture, who were understood as the major arts. With the arising
complexity of today’s society, and due to the need of high speed mass
production, were more time is always associated with more money costs,
the production methods changed radically and with them the way design
production is made.
