About industrial engineer job

What can we say about an industrial engineering job?

An industrial engineer’s job is to find the best combination of people, tools, materials, parts, information and power to provide products or services efficiently. In contrast to other engineering specialties such as civil engineering or mechanical engineering, industrial engineering track isn’t restricted to one industry or type of work. It may be industrial in the sense of working in a traditional manufacturing, mining or transportation environment. Or it can lead to work for a financial services firm, a government agency or a magazine publisher.

Industrial engineers research, analyze, model and test whole systems. They’re efficiency experts; safety engineers; ergonomics engineers; environmental health engineers; and in many cases, managers, principals or business owners. Al most any organization that you can name has a need for someone who understands what all the factors affecting its mission are, how they’re related, and what can be done to make it all work better. That’s what industrial engineering does – it makes a system, a process or an organization work better.

What is the concept of Industrial Engineering

What is the concept of Industrial Engineering

In order to maximize his earnings and enhance his living standards, man has always attempted to improve his processes, methods and tools in order to improve the productivity of his resources. That continued effort gave birth the joint of Industrial Engineering and Production Management.

About the concept of Industrial Engineering, some books and autors tell us that Industrial Engineering is concerned with the design, improvement and installation of integrated system of men, material and machines for the benefit of mankind. It draws upon specialized knowledge and skills in the mathematical and physical sciences together with the principles and methods of engineering analysis and design to specify predict and evaluate the results to be obtained from such systems.

The Hawthorne Experiment and the developing of Industrial Engineering

The Hawthorne Experiment and the developing of Industrial Engineering

A major episode in the quest to understand behavioral aspects was the series of studies conducted at the Western Electric Hawthorne plant in Chicago between 1924 and 1932. These studies originally began with a simple question: How does workplace illumination affect worker productivity? Under sponsorship from the National Academy of Science, a team of researchers from the Massachusetts Institute of Technology (MIT) observed groups of coil-winding operators under different lighting levels. They observed that productivity relative to a control group went up as illumination increased, as had been expected. Then, in another experiment, they observed that productivity also increased when illumination decreased, even to the level of moonlight. Unable to explain the results, the original team abandoned the illumination studies and began other tests on the effect of rest periods, length of work week, incentive plans, free lunches, and supervisory styles on productivity. In most cases the trend was for higher than normal output by the groups under study.

Approaching the problem from the perspective of the “psychology of the total situation,” experts brought in to study the problem came to the conclusion that the results were primarily due to “a remarkable change in the mental attitude in the group.” Interpretations of the study were eventually reduced to the simple explanation that productivity increased as a result of the attention received by the workers under study. This was dubbed the Hawthorne effect. However, in subsequent writings this simple explanation was modified to include the argument that work is a group activity and that workers strive for a sense of belonging—not simple financial gain—in their jobs. By emphasizing the need for listening and counseling by managers to improve worker collaboration, the industrial psychology movement shifted the emphasis of management from technical efficiency—the focus of Taylorism—to a richer, more complex, human-relations orientation.

Methods Engineering and Work Simplification in Industrial Engineering

Methods Engineering and Work Simplification in Industrial Engineering

These reactions led to an increased interest in the work of the Gilbreths. Their efforts in methods analysis, which had previously been considered rather theoretical and impractical, became the foundation for the resurgence of industrial engineering in the 1920s and 1930s. In 1927, H. B. Maynard, G. J. Stegmerten, and S. M. Lowry wrote Time and Motion Study, emphasizing the importance of motion study and good methods. This eventually led to the term methods engineering as the descriptor of a technique emphasizing the “elimination of every unnecessary operation” prior to the determination of a time standard. In 1932, A. H. Mogenson published Common Sense Applied to Time and Motion Study, in which he stressed the concepts of motion study through an approach he chose to call work simplification. His thesis was simply that the people who know any job best are the workers doing that job. Therefore, if the workers are trained in the steps necessary to analyze and challenge the work they are doing, then they are also the ones most likely to implement improvements. His approach was to train key people in manufacturing plants at his Lake Placid Work Simplification Conferences so that they could in turn conduct similar training in their own plants for managers and workers. This concept of taking motion study training directly to the workers through the work simplification programs was a tremendous boon to the war production effort during World War II.

The first Ph.D. granted in the United States in the field of industrial engineering was also the result of research done in the area of motion study. It was awarded to Ralph M. Barnes by Cornell University in 1933 and was supervised by Dexter Kimball. Barnes’s thesis was rewritten and published as Motion and Time Study: the first full-length book devoted to this subject. The book also attempted to bridge the growing chasm between advocates of time study versus motion study by emphasizing the inseparability of these concepts as a basic principle of industrial engineering.

Another result of the reaction was a closer look at the behavioral aspects associated with the workplace and the human element. Even though the approach taken by Taylor and his followers failed to appreciate the psychological issues associated with worker motivation, their work served to catalyze the behavioral approach to management by systematically raising questions on authority, motivation, and training. The earliest writers in the field of industrial psychology acknowledged their debt to scientific management and framed their discussions in terms consistent with this system.

Industrial Engineering and the post–world war I era

Industrial Engineering and the post–world war I era

By the end of World War I, scientific management had firmly taken hold. Large-scale, vertically integrated organizations making use of mass production techniques were the norm. Application of these principles resulted in spectacular increases in production. Unfortunately, however, because increases in production were easy to achieve, management interest was focused primarily on the implementation of standards and incentive plans, and little attention was paid to the importance of good methods in production. The reaction of workers and the public to unscrupulous management practices such as “rate cutting” and other speedup tactics, combined with concerns about dehumanizing aspects of the application of scientific management, eventually led to legislation limiting the use of time standards in government operations.

About Quality control

About Quality control

Quality control is a process employed to ensure a certain level of quality in a product or service. It may include whatever actions a business deems necessary to provide for the control and verification of certain characteristics of a product or service. The basic goal of quality control is to ensure that the products, services, or processes provided meet specific requirements and are dependable, satisfactory, and fiscally sound.

Essentially, quality control involves the examination of a product, service, or process for certain minimum levels of quality. The goal of a quality control team is to identify products or services that do not meet a company’s specified standards of quality. If a problem is identified, the job of a quality control team or professional may involve stopping production temporarily. Depending on the particular service or product, as well as the type of problem identified, production or implementation may not cease entirely.

Usually, it is not the job of a quality control team or professional to correct quality issues. Typically, other individuals are involved in the process of discovering the cause of quality issues and fixing them. Once such problems are overcome, the product, service, or process continues production or implementation as usual.

Quality control can cover not just products, services, and processes, but also people. Employees are an important part of any company. If a company has employees that don’t have adequate skills or training, have trouble understanding directions, or are misinformed, quality may be severely diminished. When quality control is considered in terms of human beings, it concerns correctable issues. However, it should not be confused with human resource issues.

Often, quality control is confused with quality assurance. Though the two are very similar, there are some basic differences. Quality control is concerned with the product, while quality assurance is process–oriented.

Even with such a clear-cut difference defined, identifying the differences between the two can be hard. Basically, quality control involves evaluating a product, activity, process, or service. By contrast, quality assurance is designed to make sure processes are sufficient to meet objectives. Simply put, quality assurance ensures a product or service is manufactured, implemented, created, or produced in the right way; while quality control evaluates whether or not the end result is satisfactory.

Gantt’s ideas covered a wider range than some of his predecessors. He was interested not only in standards and costs but also in the proper selection and training of workers and in the development of incentive plans to reward them. Although Gantt was considered by Taylor to be a true disciple, his disagreements with Taylor on several points led to the development of a “task work with bonus” system instead of Taylor’s “differential piece rate” system and explicit procedures for enabling workers to either protest or revise standards. He was also interested in scheduling problems and is best remembered for devising the Gantt chart: a systematic graphical procedure for planning and scheduling activities that is still widely used in project management.

In attendance were also the profession’s first educators including Hugo Diemer, who started the first continuing curriculum in industrial engineering at Pennsylvania State College in 1908; William Kent, who organized an industrial engineering curriculum at Syracuse University in the same year; Dexter Kimball, who presented an academic course in works administration at Cornell University in 1904; and C. Bertrand Thompson, an instructor in industrial organization at Harvard, where the teaching of Taylor’s concepts had been implemented. Consultants and industrial managers at the meeting included Carl Barth, Taylor’s mathematician and developer of special purpose slide rules for metal cutting; John Aldrich of the New England Butt Company, who presented the first public statement and films about micro- motion study; James Dodge, president of the Link-Belt Company; and Henry Kendall, who spoke of experiments in organizing personnel functions as part of scientific management in industry. Two editors present were Charles Going of the Engineering Magazine and Robert Kent, editor of the first magazine with the title of Industrial Engineering. Lillian Gilbreth was perhaps the only pioneer absent since at that time women were not admitted to ASME meetings.

Another early pioneer was Harrington Emerson. Emerson became a champion of efficiency independent of Taylor and summarized his approach in his book, the Twelve Principles of Efficiency. These principles, which somewhat paralleled Taylor’s teachings, were derived primarily through his work in the railroad industry. Emerson, who had reorganized the work shops of the Santa Fe Railroad, testified during the hearings of the Interstate Commerce Commission concerning a proposed railroad rate hike in 1910 to 1911 that scientific management could save “a million dollars a day.” Because he was the only “efficiency engineer” with firsthand experience in the railroad industry, his statement carried enormous weight and served to emblazon scientific management on the national consciousness. Later in his career he became particularly interested in selection and training of employees and is also credited with originating the term dispatching in reference to shop floor control, a phrase that undoubtedly derives from his railroad experience.
