Key Facts & Information
|Overview||You've probably heard the expression "build a better mousetrap." Industrial engineers are the people who figure out how to do things better. They find ways that are smarter, faster, safer, and easier, so that companies become more efficient, productive, and profitable, and employees have work environments that are safer and more rewarding. You might think from their name that industrial engineers just work for big manufacturing companies, but they are employed in a wide range of industries, including the service, entertainment, shipping, and healthcare fields. For example, nobody likes to wait in a long line to get on a roller coaster ride, or to get admitted to the hospital. Industrial engineers tell companies how to shorten these processes. They try to make life and products better-finding ways to do more with less is their motto.|
|Key Requirements||Wide interests in both engineering and business, excellent math, logic, and communication skills, preference for the big picture, but still able to analyze small details|
|Minimum Degree||Bachelor's degree|
|Subjects to Study in High School||Biology, chemistry, physics, computer science, geometry, algebra II, pre-calculus, calculus, English; if available, statistics, business.|
|Projected Job Growth (2010-2020)||More Slowly than Average (3% to 6%)|
|Interview||Read these interviews to see what industrial engineers say about their work—why they decided to become industrial engineers, what they like most about their work, what has been their most interesting project, and what they think is their most important contribution.|
Education and Training
To become an industrial engineer, you must have a bachelor's degree in industrial engineering. Recommended coursework includes statistics, computer skills, ergonomics, management science, quality control, sociology, psychology, organizational behavior, economics, finance, labor relations, and mathematics. Those who plan to specialize in manufacturing areas find it useful to study shipping, billing, and automated systems, along with computer science.
Graduate programs in industrial engineering are primarily for those who wish to enter academia. Employers consider production or manufacturing experience extremely useful; they also favorably view administrative experience in large-paperwork industries (such as insurance, health care, or brokerage). Many find joining a professional organization supportive of their careers (some join while still in school) because it helps them to keep them abreast of important topics and trends in industrial engineering.
Engineers should be creative, inquisitive, analytical, and detail oriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication abilities are becoming increasingly important as engineers frequently interact with specialists in a wide range of fields outside engineering.
Nature of the Work
Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs.
Industrial engineers determine the most effective ways to use the basic factors of production—people, machines, materials, information, and energy—to make a product or provide a service. They are primarily concerned with increasing productivity through the management of people, methods of business organization, and technology. To maximize efficiency, industrial engineers carefully study the product requirements and design manufacturing and information systems to meet those requirements with the help of mathematical methods and models. They develop management control systems to aid in financial planning and cost analysis, and design production planning and control systems to coordinate activities and ensure product quality. They also design or improve systems for the physical distribution of goods and services and determine the most efficient plant locations. Industrial engineers develop wage and salary administration systems and job evaluation programs. Many industrial engineers move into management positions because the work is closely related to the work of managers.
Most industrial engineers work in industry for manufacturing or service companies. But since their skills are so versatile, industrial engineers can work in virtually any kind of industry or organization, including government agencies and consulting firms. They typically work standard 40-hour work weeks.
