What is the difference between a software designer and a software developer?

The major difference between a software designer and software developer is that the developer executes the ideas of the designer. The developer’s responsibilities are to go from a concept to an actual application that attempts to address the problems that the designer has identified. Although designers are typically proficient in programming and software development, they are not as heavily involved in the actual development project. Designers also use modeling languages, which are significantly different from programming languages.
