Designer

A designer who designs something. Perhaps the broadest definition is that provided by psychologist Herbert Simon: 'Everyone designs who devises courses of action aimed at changing existing situations into preferred ones. Entry to some design professions is strictly controlled or limited by legal requirements, but use of the title 'designer' is generally un-regulated.

As well as amateur designers, there are many professional designer To become a professional designer usually requires study to degree level and certain work experience or training. Working as a designer usually implies being creative in a particular area of expertise. There can be great differences between the working styles and principles of designers in different professions.  

Designers are usually responsible for developing the concept and making drawings or models for something new that will be made by someone else. Their work takes into consideration not only how something will look, but also how it will be used and how it will be made. Design engineers, in contrast, are more concerned with designing a particular new product or system.

The design engineer usually leads the project, designing the overall frameworks and the most far reaching parts, and directing the designers on sub-system design on the project's more routine parts as necessary. He may work with industrial designers and marketing to develop the product concept and specifications and directs the design effort from that point.
