This process applies to many different products, such as chemicals, computers, gas turbines, helicopters, and toys. In addition to design and development, many engineers work in testing, production, or maintenance. These engineers supervise production in factories, determine the cause of breakdowns, and test manufactured products to maintain quality. They also estimate the time and cost to complete projects. Some work in engineering management or in sales, where an engineering background enables them to discuss technical aspects and assist in product planning, installation, and use.
Most engineers specialise.
More than 25 major specialities are recognised by professional societies, and the major branches have numerous subdivisions. Engineers may also specialise in one industry such as motor vehicles or in one field of technology, such as jet engines or semiconductor materials.
