Henry Ford


Automobile manufacturer Henry Ford who was the first of eight children of William and Mary Ford was born July 30, 1863 on the family farm near Dearborn, Michigan. Ford was helping his father with the harvest. In 1891, Ford became an engineer with the Edison Illuminating Company in Detroit. His promotion to Chief Engineer in 1893 gave him enough time and money to establish his company. These experiments showed in 1896 with the finalizing of his own self-propelled vehicle-the Quadricycle. The Quadricycle had four wire wheels. Although Ford was not the first to build a self-propelled vehicle with a gasoline engine, he was, however, one of several automotive pioneers who helped this country become a nation of motorists. After two unsuccessful attempts to establish a company to produce automobiles, he formed the Ford Motor Company in 1903 as vice-president and chief engineer. In 1908, he introduced the Model T, which dominated the industry for a decade. This vehicle initiated a new time in personal transportation and shorthly became huge succes. Because of wanting the Model T, the company opened a large factory at Highland Park, Michigan, in 1910. Here, Henry Ford combined accuracy manufacturing, standardized and interchangeable parts, a division of labor, and, in 1913, a continuous moving assembly line. Ford's production of Model Ts made his company the largest automobile manufacturer in the world. Aerial view of the Rouge Plant in 1930:

Frank Bunker GILBRETH- Lillian Moller GILBRETH (GILBRETHS)


The Gilbreths are American industrial engeneer. They developed the method of time-and-motion study which is analysis of the time spent in going through the different motions of a job or series of jobs. Frank Gilbreth was concerned with the relationship between human beings and human effort until his death in 1924. He developed many improvements in brick-laying. Frank and Lillian Gilbreth pioneered in the use of motion pictures for studying work and workers. After Frank Gilbreth's death, Dr. Lillian Gilbreth continued the work and extended her work into the home to find the "One Best Way" to present household tasks and she developed continuous quality improvement (CQI) which is the meta process for most management systems. She is identified as one of the world's great industrial and management engineers and she has worked in many countries of the world. In 1907, Frank met Frederick Winslow Taylor and became an admirer of the Taylor System of time study and Frank created useful the Taylor Society. In 1912, the Gilbreths left this process and focused their attention on scientific management consulting. They broke with Taylor in 1914 and created their own scientific management, which focused on the human element as well as the technical.

Frederick W. TAYLOR

Frederick Winslow Taylor who produced scientific management in business is American industrial engineer. He was born in Germantown (now part of Philadelphia), Pennsylvania. Taylor first learned to use time as a management tool while attending Philips Exeter Academy. Taylor passed the entrance examination to Harvard College but did not register. After he completed an engineering degree at the Stevens Institute of Technology in Hoboken, New Jersey. In 1878, he started working at the Midvale Steel Company. He became foreman of the steel plant. Taylor developed detailed systems in order to obtain maximum productivity from both workers and machines in the company. He thought in finding the right jobs for workers, and then paying them well for the increased output. These systems trusted in time and motion studies. In 1890, Taylor became general manager of the Manufacturing Investment Company and created the new branch of management consultant. In 1898 while at Bethlehem, he became discoverer of the Taylor-White process, which is a method of tempering steel. His management methods were published in The Principles of Scientific Management.
The Science of Work
Frederick Winslow Taylor planned a system in order to create the efficient work enviroment. While industrial revolution-era innovators advanced quality control in the workplace, Taylor formalized these principles and promoted them to eager industrial managers to increase performance.
Scientific Publication
Taylor retired at age 45 but still he dedicated time and money to promote his principles of scientific management. In 1906, Taylor was elected president of The American Society of Mechanical Engineers. In 1909 he published his work which he is famous for, The Principles of Scientific Management. Considering himself a reformer, Taylor suggested seriously the ideals and principles of his system of management until his death from influenza in 1915. Today his system of industrial management continues to influence the development of modern industry around the world.

Henry FAYOL

Henry Fayol was French pioneer of management theory. Fayol who managing director of a mining and metallurgical company in France was studied and developed his theory in such a way that the business procedures. His theory published in a titled General and Industrial Management (1916). This little book includes the first theory of general management and statement of management principles. He suggested that managerial activity should include five primary functions of management: forecasting and planning; organizing; commanding; coordinating; and controlling. Fayol thought that management is a universal human activity and thought that it is important to have unity of command. Although his ideas have become a universal part of the modern management concepts, some writers compare him with Frederick Winslow Taylor. Fayol developed a list of basic management principles for achieving a good organization. Some of these principles are division of work, discipline, unity of direction, remuneration of employees, scalar chain, equity, initiative, authority and responsibility, unity of command, subordination of individual interest to general interest, centralization, order, stability of personnel, esprit de corps. Although there are various elements in Fayol's theroy, the best importants of elements are logic, rationality, and consistency.

Max WEBER

Max Weber is known as one of the leading scholars and founders of modern sociology. Moreover, Weber accomplished much economic work in the style of the "youngest" German Historical School. Max Weber Studies seeks fundamental issues in the social and historical sciences: the dilemmas of life-conduct and vocation in the contemporary world, the tracking of rationalization processes and their impact, disenchantment and the return of magic, the 'uniqueness of the West' and multiple modernities, the analysis of the stratification of power and its modalities, and the validity of an interpretative science of social reality. Weber was known his study, Protestant Ethic and the Spirit of Capitalism (1904–1905), which was originally published as two articles in a scholarly journal. In this study he demonstrated why northern European Protestant behavior was more helpful than were southern European Catholic beliefs and practices. However, he also contributed fundamental works to the sociology of law, the sociology of music, the sociology of the economy, the philosophy of social science method, the comparative sociology of religion, social stratification, the sociology of bureaucracy, and of power and charisma, and so on. His major work is Economy and Society (1922). Weber's thoughts about science and ethics are summarized in two famous lectures "Science as a Vocation" (November 1917) and "Politics as a Vocation" (January 1919). Weber drew on Friedrich Nietzsche, Leo Tolstoy, the Sermon on the Mount, Charles-Pierre Baudelaire, Immanuel Kant, and his young friend, Georg Lukács (1885–1971). In the lecture of "Politics as a Vocation," Weber explained one of his most famous distinctions, between an ethic of ultimate ends and an ethic of responsibility. As Weber explained in one of his most famous and controversial paragraphs: We must be clear about one of two fundamentally differing and irreconcilably opposed maxims: conduct can be oriented to an "ethic of ultimate ends" or to an "ethic of responsibility." There is an terrible contract between conduct that follows the maxim of an ethic of ultimate ends—that, is in religious terms, "the Christian does rightly and leaves the results with the Lord"—and conduct that follows the maxim of an ethic of responsibility, in which case one has to give an account of the foreseeable results of one's action.

Abraham MASLOW

Abraham Harold Maslow (April 1, 1908 – June 8, 1970) was an American psychologist. He studied a "hierarchy of human needs", and is considered the father of humanistic psychology. Maslow's primary contribution to psychology is his Hierarchy of Needs. Maslow claimed that humans have a number of needs that are instinctoid, that is, innate. These needs are classified as "conative needs," "cognitive needs," and "aesthetic needs." "Neurotic needs" are included in Maslow's theory but do not exist within the hierarchy. Maslow assumed that needs are arranged in a hierarchy in terms of their power. The lower the need is in the pyramid, the more powerful it is. The higher the need is in the pyramid, the weaker and more distinctly human it is. The first four layers of the pyramid are what Maslow called "deficiency needs" or "D-needs:" Needs beyond the D-needs are "growth needs," "being values," or "B-needs." The base of the pyramid is the physiological needs, including the biological requirements for food, water, air, and sleep. The second level included the needs for structure, order, security, and predictability . The third level which is the need for love and belonging included the needs for friends and companions, a supportive family, identification with a group, and an intimate relationship. The fourth level is the esteem needs. This group of needs requires feelings of prestige, acceptance, and status, and self-esteem that results in feelings of adequacy, competence, and confidence. Finally, self-actualization sits at the apex of the original pyramid. Maslow's theory of human needs draws strongly on the pioneering work of Henry Murray (1938).

A.

Engineering cames from the earliest times when humans began to make clever inventions, such as the pulley, lever, or wheel, etc. The word "engine", derives from the Latin ingenium, meaning "innate quality, especially mental power, hence a clever invention." Therefore an engineer is essentially someone who makes useful or practical inventions. Meaning of engineer is "a constructor of military engines" in 1325. Engineering was originally divided into military engineering which included construction of fortifications as well as military engines, and civil engineering, involved in non-military projects, such as bridge construction.

B.

A profession is a learning to advanced knowledge, understanding and abilities gained from intensive and specialized education, training and practical experience. The engineering profession is defined to be self-regulating.

C.

Engineers are problem solvers. They are concerned with solving problems by using technology materials. While they are doing this, they rely on their creativity and academic skills and they use mathematics, science, and computers to model real life situations.

D.

Chemical engineers: Develop processes and products made with chemicals perhaps in the food, petroleum, or pharmaceutical industries.
Civil engineers: Design roads, buildings, transportation systems, and other large-scale construction projects.
Electrical and computer engineers: Design, construct, and maintain electronic systems, which may include working with computer chips, circuits and electronic communications.
Geological engineers: Solves earth related technical problems while at the same time protecting the environment.
Industrial engineers: Plan and design industrial and business facilities for the best product quality and employee working conditions.
Mechanical engineers: Create machines and may work on transportation systems, power production or performance analysis.
Materials engineers: Study metals, ceramics, plastics, and composites to design materials for applications that may involve transportation, communication or power production.
Other engineering disciplines apply skills to very specific areas. However, industrial engineering design processes and systems that improve quality and productivity by using knowledge of engineering, mathematics, business administration, and management. Moreover Industrial Engineers work and consult in every industry, including hospitals, communications, e-commerce, entertainment, finance, food, insurance, banking, travel, and transportation.

DESIGN CONCEPT OF THE GROUP-1

A. Brainstorm Process

In this period which is before designing the board;
· For recycled and eco-friendly material; we took into consideration fiberglass, Styrofoam, aluminium, chrome, wood plastic composite (WPC), cardboard, and flexible glass.
· For functionality; we took into consideration a board which can be converted to a table or a scooter, a multi-framed board, a board with an illumination system, a board which can also be used without posters, and embedded potholders.
· For ergonomics and aesthetics; we took into consideration edges with sponge, filleted corners, suitability for holding up, a human-looking board, and a smiling face.
· For portability; we took into consideration embedded rollers, ball rollers, multi-rollers, rollers which can be immobilized, and an easy transportable board without rollers.
· For storability and demountability; we took into consideration a collapsible board, a collapsible frame or stand, and edges with sliding bar.
· For easy poster placement and removing; we took into consideration edges with duct, and a sliding bar with file attachment.
· For market success and attraction; we took into consideration phosphor, a board drawing attraction of the fans of any team, and a smiling face.

We also took into account cheapness, lightness, stability, conforming to mass production and producibility by physically handicapped people.

B. About the Project

For the board that we came to the point of designing:
· For recycled and eco-friendly material; we chose aluminium because of its lightness quality.
· For functionality; we decided to design a board which can be used without any poster, because the other options would not be suitable for physically handicapped people to produce.
· For ergonomics and aesthetics; we preferred to use filleted corners and catch the suitability for holding up, because with this features, it is easier to use the board.
· For portability; we chose an easy transportable board because it was risky to use a system with rollers in terms of stability.
· For storability and demountability; we preferred sliding bar system because the other options are not as efficient and practical as this one.
· For easy poster placement and removing; we decided to use ducted frame since this one is more original.
· For market success and attraction; we made a decision to use phosphor and a smiling face in order to show our creativity.
We preferred home products for cheapness, frail materials for lightness, materials which can be standardized for mass production, aluminium as a main material for stability, and lastly by decreasing the workshop need we designed a board which can also be produced by physically handicapped people.

C. Use of Board

The closed form of our board which is shown in CADKey-1-2 drawing turns into its full form (CADKey-3-4-5) by pulling the potholder upwards and then pulling two sides of the coming part. While pulling the sides, two-rolled system constitutes the back side and front side of the frame. Finally, the parts which stand adjacent with the closed form help the sides of the board stand balanced.


D. Materials

· Main material: Aluminium
· Base: Non-sliding plastic material
· Back side: Organic cloth
· Front side: Acetate

E. Process

· Brainstorming and designing
· The study of feasibility for the prototype
· Research for appropriate prices
· Providing the materials
· Production

DIVISION OF LABOR-ASSEMBLY LINE-MASS PRODUCTION

Division of Labor

Division of labour is the specialisation of cooperative labour. Division of labor limited tasks and roles in order to increase the efficiency of labour. Generally the growth of a more and more complex division of labour is closely associated with the growth of total output and business, the rise of capitalism, and the complexity of industrialisation processes. The division of labor is the source of economic interdependence.

Adam Smith and Division of Labor

The main focus of Adam Smith's The Wealth of Nations is the concept of economic growth. Growth, according to Smith, is based on the increasing division of labor. This idea shows that the breaking down of large jobs into many tiny components is necessary. According to this idea, each worker becomes an expert in one isolated area of production, thus his productivity increases. Productive labor, to Smith, realizes two important requirements. First, it must "lead to the production of tangible objects." Second, labor must "create a surplus" which can be reinvested into production.
Another main concern for Smith involved tracing the roots of value. He identified this two different kinds of value, "use value" and "exchange value." The exchange value interested Smith considerably.

Global Division of Labour


There are few comprehensive studies of the global division of labour.In one study, Deon Filmer guesses that 2,474 million people participated in the global non-domestic labour force in the mid-1990s. Of these,
around 15%, or 379 million people, worked in industry,
a third, or 800 million worked in services, and
over 40%, or 1,074 million, in agriculture.
The majority of workers in industry and services were wage & salary earners - 58 percent of the industrial workforce and 65 percent of the services workforce. But a big portion were self-employed or involved in family labour. Filmer suggests the total of employees worldwide in the 1990s was about 880 million, compared with around a billion working on own account on the land (mainly peasants), and some 480 million working on own account in industry and services.

Advantages of Division of Labor

1.More efficient in terms of time.
2.Reduces the time needed for training because the task is simplified.
3.Increases productivity because training time is reduced and the worker is productive in a short amount of time.
4.Concentration on one repetitive task makes workers more skilled at performing that task.
5.Little time is spent moving between tasks so overall time wasted is reduced.
6.The overall quality of the product will increasingly bring welfare gains to the consumer

Disadvantages of Division of Labor

1.Lack of motivation: the quality of labour decreases while absenteeis may rise.
2.Growing dependency: a break in production may cause problems to the entire process.
3.Loss of flexibility: workers have limited knowledge while not many jobs opportunities are available.
4.Higher start-up costs: high initial costs necessary to buy the specialist machinery lead to a higher break-even point.

Assembly Line



An assembly line is a producing in which parts are added to a product in a sequential manner using optimally planned logistics to create a finished product much faster than with handcrafting-type methods. The best known form of the assembly line was realized into practice by Ford Motor Company between 1908 and 1913, and made famous in the following decade by the social branchs of production. Assembly line technology is necessary for a worker to focus his or her attention on one small part of the production process.

Mass Production

Mass production is the method of producing goods in large quantities at low cost per unit. Although mass production allows lower prices, it does not have to mean low-quality production. The mass production process is described by mechanization to achieve high volume, elaborate organization of materials flow through various stages of manufacturing, careful supervision of quality standards, and minute division of labour. To make it beneficial, mass production requires mass consumption. Until relatively recent times the only large-scale demand for standardized, uniform products came from military organizations. The major experiments that eventually led to mass production were first performed under the aegis of the military.
