Industries & Professions /
The engineering industry comprises many fields of study, all employing unique and sometimes similar methods of science to reach practical solutions to problems and questions in all industries. There are five basic areas of study in which engineers in all branches of the industry can specialize: research, development, application, management, and maintenance. While an engineer may work exclusively in one of these areas, it is more common for their knowledge and duties to overlap. For example, research and development are commonly linked and called R&D. Those working in the application side of a project may often find themselves making maintenance calls.
