"Industrial Engineering is System Efficiency Engineering and  Human Effort Engineering."

It is concerned with engineering products and engineering processes primarily. It continuously improves engineering elements of products and processes as the opportunity arises to increase efficiency and productivity. Various other activities that plan and control engineering products and processes are also improved by industrial engineers to assure the productivity of the engineering processes or the engineering system as a whole. Industrial engineers also focus on the study and improvement of human effort in engineering processes.

AIIE


“Industrial engineering is concerned with the design, improvement, and installation of integrated systems of men, materials, and equipment. It draws upon specialized knowledge and skill in the mathematical, physical, and social 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.” (AIIE, 1955).

It is important that industrial engineers have to recognize that scientific management was evaluated by Lilian Gilbreth, a psychologist, from a human behavior  perspective

and a positive opinion was given. Industrial engineering appeared as a part of the scientific management and engineering developed to reduce cost of products made using engineering methods.

Lean Assembly Line Layout Do’s and Don’ts

May 9, 2019


A lean-based approach to line layout differs from traditional techniques. For instance, lean layouts often use some type of an andon system to address issues such as production status, quality checks and abnormalities.


Lean layouts also rely heavily on product and process planning (3P) methodologies.


“We call it production preparation,” says David Pate, vice president of TBM Consulting Group. “It involves layout design that can apply to either an individual workcell or an entire plant.”


According to Pate, any layout project using this method should address the following criteria:


Enable material flow to and from the line.

Allow people to interface easily and quickly in a flexible environment.

Ensure that all equipment is as versatile as possible.

Don’t create monuments. “Smaller, moveable equipment is better than large, monolithic items,” claims Pate.

Make it easy to change over.

Minimize wasted motion.

Separate people and machines.

Enable the use of pull systems.

Fact Gathering for Office System Efficiency Engineering Studies

Office Work Study - Industrial Engineering

The staff members are asked to write down their job description as they feel they are doing it, under various heads, for a representative period – work, month etc. They are asked to prepare a statement of duties and responsibilities under selected heads and to make an estimate of the total attendance time devoted to each activity as well as time absorbed by miscellaneous affairs, waiting, etc.

___________________________________________

Relevant Facts


A large part of system efficiency studies consists of getting facts.  The fact collection must be done selectively and as economically as possible. In gathering facts, the nature and amount of work, its purpose, the people who do it, the place and time of doing it, and the methods used are to be ascertained.

Nature


What is done?
The process and the result are to be recorded.

Amount


Can a measure be found for each action?
Words and answers like ‘often’ or ‘frequently’ need to challenged and efforts are to be made to get a numerical estimate of the frequency.

Purpose


Why is the work done?

Persons


Who does the work?

Place


Where is the work done?

Time


When is the work done?

Means


How is the work done?
This includes method, movement, equipment and supervision.

 Methods of collecting and getting information


Information provided through records


Organization charts, work distribution lists, work statistics, statements of procedures and actions taken reports etc. are useful and valuable sources of information.

Job description by staff


The staff members are asked to write down their job description as they feel they are doing it, under various heads, for a representative period – work, month etc. They are asked to prepare a statement of duties and responsibilities under selected heads and to make an estimate of the total attendance time devoted to each activity as well as time absorbed by miscellaneous affairs, waiting, etc.

Direct observation of work


The system study person can himself observe procedures and record. He can discuss various steps of the procedure with the employee concerned at the time of observation.

Interview and discussion


Interviewing is a most important part of the fact collection exercise. Arrangement for an interview should always be made through, or with the knowledge of, the immediate supervisor of the person to be interviewed. The system study person should make a rough plan of the enquiry indicating the kind of information needed and the scope of enquiry based on the job description provided to him by the organization as well as the employee concerned.

During an interview the analyst should have an informal manner. He should take great trouble to put the other person at ease. He must pose his questions carefully, avoiding anything which implies criticism of the individual, or of the work done, or which may be interpreted as injuring prestige. He should be impersonal, making it clear that he is engaged upon a study of the work and is not probing into the actions of the individuals. He needs to play down any idea that he is an expert in the specific work and stress the value of the main features of efficiency study approach. It helps if he uses the term ‘we’ rather than ‘I’ in conversation and interview. He should listen patiently and attentively – but also be able to guide the conversation over the required subject matter without dominating it.

As far as possible, interviews should be time to suit the work requirements and staff convenience. Normal work should not be seriously disturbed. Incoming telephone calls, enquiries and the like must be recognized as inevitable disturbances; the extent of such interruptions, the reasons for them and the manner n which they are treated may provide useful information about the job.

The best point at which to examine work is where it is done; this may mean that interviews are undertaken by the side of the desk where the employee is functioning.

Written questionnaires


Written questionnaires can be used where more number of similar jobs are being performed to get information in a structured manner.


Discussions with senior staff


Discussion with senior staff regarding the facts recorded for each staff member may reveal additional facts.

Sampling


Sampling studies are undertaken to record relevant facts.

The Practice of Motion Study - Gilbreth - Part 1 - Part 2 - Part 3 - Part 4 - Part 5


THE EFFECT OF MOTION STUDY UPON THE WORKERS 


(Published in the " The Annals " of the American Academy of Political and Social Science, Philadelphia, May, 1916. Publication No. 1000. )

Motion study consists of analysing an activity into its smallest possible elements, and from the results synthesising a method of performing the activity that shall be more efficient, the word " efficient " being used in its highest sense. 

We find it of utmost importance and mutually advantageous from every standpoint, to gain the full and hearty co-operation of the worker at once, and to enlist him as a co-worker in the motion study from the moment the first investigation is made. Our methods of making motion study are by the use of the micromotion, simultaneous motion cycle chart, and chronocyclegraph methods. The process of making motion and time studies through the use of the cinematograph, the microchronometer and the cross-sectioned screen have been so reduced in cost as to make them indispensable even from the cost standpoint in motion study.

It is imperative that the worker shall understand what is being done and why, and make it most profitable to every one that- the worker shall be able, as well as willing, to help in the work of obtaining methods of least waste by means of motion study. The process of motion study is made even more effective and  economical when the worker, or the observed man, does his best work, and endeavours to take a part of active initiative in deriving the motion standards. We find in our practice that the worker is only too glad to do this. In fact, it is usually he, oftener than the observer, who cries out, "Wait a moment till this is done in the best way possible," or "Wait a moment, please, I know a way that I believe is easier." Similarly, when using the chronocyclegraph device; the worker is not only interested in the electric lights and their various paths and orbits of dots and dashes, but is most anxious that these paths shall be those of the greatest skill and the fewest number of motions possible. 

The various methods used with these various types of apparatus, which are usually new to the worker, present problems in psychology which are interesting to the worker as well as to the observer. The worker is quick to note that, with the new conditions attending the measuring work, his own process varies for a short time at the beginning from his unusual habits, because of the entering of the variables of the apparatus and the strange conditions that it involves. He is quick to notice, also, that this effect of strangeness soon disappears, and that he then works exactly in accordance with his normal method. This period of strangeness, far from being a dis-advantage, is, on the contrary, often a great advantage. The worker is almost sure to revert to the former habit, and an investigator or observer often gains valuable clues not only to excellent standards, but to necessary methods of teaching those standards, particularly with emphasis on eliminating interference of many wrong habits acquired in trade learning prior to conscious effort for motion economy. It is, therefore, clear that during the period of making motion studies the effect of them upon the worker is educative to the highest degree, for not only does he become interested in what he does, but he learns to think of all activity in terms of motions and elements of motions. The by-products of this are also important, as he is always able afterwards to learn new work much faster and with comparatively little coaching, and as he has that success that usually attends the work of one who knows the least wasteful method of attack of learning the new problems or performing the new task. 

The effects of motion study are particularly striking upon the observer or the man actually making the studies. This is true not only during the time of making the observation, but also during the time spent in embodying the data derived in simultaneous cycle motion charts and in motion models. These motion models, which are wire representations of the paths of the motion, made from the stereoscopic records derived from the chronocyclegraph process have a peculiar educative value that is well embodied in the following statement of a young engineer who spent some time making motion models as a part of that thorough training for motion and time study man which we believe so necessary : 

"After making a number of models of motions I have changed from a scoffer to a firm believer. I believe not only in their value as an aid to the study of the psychology of motions, but also as to their educational value in the teaching of the motion study man. 

"I consider them of the same value to the motion study man as is the model of an engine or a mechanical device to an engineer. If the engineer was to study, for instance, a railroad engine, and the only chance he had to study was to watch an engine going by him at express train speed, his impression as to the mechanical working of the engine would be, to say the least, vague. 

"A motion, in itself, is intangible, but a model of a motion gives one an altogether different viewpoint, as it seems to make one see more clearly that each motion leaves a definite path, which path may be subjected to analysis. 

"I have made motion studies since making models, and what I learned from making the models has convinced me of their value. In former motion studies which I have made, my attention was always divided, more or less equally, between the direct distance between the starting and finishing points of the motion, the equipment, and the surroundings. I have found that, since seeing a motion, as represented by a model, I am better able to concentrate first on the motion itself, and then upon the variables which affect the motion. This seems to me a more logical method, and I know that I have had better results. 

" I believe a good method of illustrating how a motion model helps one to visualise is to compare it with the wake left by an ocean liner. When one stands at the stern of a liner, which changes its course often, and watches the wake he can visualise the changes more readily than when unable to see the wake." It is interesting to note here not only the interest aroused intensively in the subject of motion study itself, but also extensively in the correlation of processes in the industries with general processes outside. The motion study man is a specialist who, because of his work, spends a large amount of time in the close study of motions, but to some extent this intensive and extensive interest is aroused in all those engaged in motion study, whether as observers or observed. 

After the results of motion study are actually installed the effects are as great or greater upon those who work under the derived standards. It must be understood that motion study always implies fatigue study,  for the best and least wasteful results cannot be obtained otherwise, and that the worker who operates under these standards, therefore, not only has time to do the work in the best way, but ample time for adequate recovery from the fatigue of his work. This procedure provides directly for his physical and mental well-being. Motion study lays particular emphasis upon this. The great bogey of all who argue against standardisation is "the awful resulting monotony." Now psychology,  as well as the results in actual practice, proves that monotony comes not from performing the activity the same way every time, but from a lack of interest involved in, or associated withy the activity. This interest is supplied not only directly by motion study, but indirectly by the other parts of measured functional management, such as devices for eliminating unnecessary fatigue and for overcoming necessary fatigue. 

Besides all this there is the interest aroused and the education resulting from the graphic representation of the results of motion study data to the worker as well as the observer. The pictures of the micromotion films are projected at the nor-mal speed of the moving picture. They are also examined one at a time. The chronocyclegraphs in three dimensions are shown through the stereoscope, on the screen, by means of the wire motion models to the workers at the foremen's and workers' meetings and are there discussed. All the traditional knowledge is literally collected, measured, sorted, tagged and labelled. These data, together with indisputable measuring methods is presented before those possessing the greatest craft skill of the old methods, and who can quickest actually learn the new knowledge and put it to use. The new knowledge is of no use to the employer without the co-operation of the worker. This fact puts the relations between the worker and his employer on a new basis. They must co-operate, or both pay an awful price. These new methods have demonstrated that there is so much to learn that the employer cannot afford to put on and lay off his employees in proportion to the receipt of orders. He must solve the problem of steady employment. He cannot afford to let his specially trained men " get away." This is of vital importance in its effect upon the mental condition and activity of the worker. 

By these means the workers, who are the actual producers of the nation, become familiar in every day experience with motion study and time study instruments of precision and with the results of their use. Such knowledge in the hands of our workers is the means of their being able to take the initiative in acquiring greater skill in all trades and in all life works. This is one of the best forms of industrial preparedness. It must be emphasised that the facts concerning motion study here stated embody not only a program but a record. The actual every day practice of motion study shows these effects on the  worker not only in the intangible results of added interest and a different attitude towards the work, but also in such tangible results as a larger number and a more profitable set of suggestions in the suggestion boxes, better attended and more profitable foremen's and workers'  meetings, a greater number of promotions, more co-operation, more reading and study of the science of management, mid higher wages earned with greater ease. 

Motion study has no right to claim all the benefits that accrue from measured functional management, but, as a part of this management,  shares in these benefits, and thus those who work under it are assured of unusually high pay, during and after the motion study, a chance for promotion, physical and mental well-being, and a co-operative atmosphere in which to work. Motion study has the right to claim as its own benefits an added interest not only in the activity involved in the particular work done in the office or plant or wherever the work place may be, but in all activity away from as well as at work. Motion study benefits employees and employers, as well as everybody else who adopts its methods, because it makes " to do," mean "to be interested' and to be interested means to be more efficient, more prosperous, and more happy.

President Roosevelt in his address to the Governors at the White House, prophetically remarked that "The conservation of our national resources is only preliminary to the larger question of national efficiency."

The whole country at once recognized the importance of conserving our material resources and a large movement has been started. But our larger wastes of human effort, which go on every day through such of our acts as are blundering, ill-directed, or inefficient, are less visible, less tangible, and are only vaguely appreciated. The larger question of national efficiency includes efficiency of human resources also.

This paper has been written:

First. To point out, through a series of simple illustrations, the great loss which the whole country is suffering through inefficiency in almost all of our daily acts.

Second. To try to convince the reader that the remedy for this inefficiency lies in systematic management of human resource with managers playing an active role reduce inefficiency in addition to efforts of working men.

Third. To prove that the best management is a true science, resting upon clearly defined laws, rules, and principles, as a foundation. And further to show that the fundamental principles of scientific management are applicable to all kinds of human activities.  And, briefly, through a series of illustrations, to convince the reader that whenever these principles are correctly applied, results must follow which are truly astounding.





"Foundation of scientific management is the foundation of industrial engineering also." - Narayana Rao


The principal object of management should be to secure the maximum prosperity for the employer, coupled with the maximum prosperity for each employee.

The words "maximum prosperity" includes the development of every branch of the business to its highest state of excellence, so that the prosperity may be permanent. In the same way maximum prosperity for each employee  also means the development of each man to his state of maximum efficiency, so that he may be able to do, generally speaking, the highest grade of work for which his natural abilities fit him, and it further means giving him,  this class of work to do.

Perhaps the majority on either side do not believe that it is possible so to arrange their mutual relations that their interests become identical. Scientific management, on the contrary, has for its very foundation the firm conviction that the true interests of the two are one and the same; that prosperity for the employer cannot exist through a long term of years unless it is accompanied by prosperity for the employee, and vice versa; and that it is possible to give the workman what he most wants--high wages--and the employer what he wants--a low labor cost--for his manufactures.


No one can be found who will deny that in the case of any single individual the greatest prosperity can exist only when that individual has reached his highest state of efficiency; that is, when he is turning out his largest daily output. In the case of a more complicated manufacturing establishment, it should also be perfectly clear that the greatest permanent prosperity for the workman, coupled with the greatest prosperity for the employer, can be brought about only when the work of the establishment is done with the smallest combined expenditure of human effort, plus nature's resources, plus the cost for the use of capital in the shape of machines, buildings, etc. Or, to state the same thing in a different way: that the greatest prosperity can exist only as the result of the greatest possible productivity of the men and machines of the establishment--that is, when each man and each machine are turning out the largest possible output. In a word, that maximum prosperity can exist only as the result of maximum productivity



Soldiering - Working at slower speed than the possible speed


There are three causes for it, which may be briefly summarized as:

First. The fallacy, which has from time immemorial been almost universal among workmen, that a material increase in the output of each man or each machine in the trade would result in the end in throwing a large number of men out of work.

Second. The defective systems of management which are in common use, and which make it necessary for each workman to soldier, or work slowly, in order that he may protect his own best interests.

Third. The inefficient rule-of-thumb methods, which are still almost universal in all trades, and in practicing which our workmen waste a large part of their effort.

This paper will attempt to show the enormous gains which would result from the substitution by our workmen of scientific for rule-of-thumb methods.



The cheapening of any article in common use almost immediately results in a largely increased demand for that article. Take the case of shoes, for instance. The introduction of machinery for doing every element of the work which was formerly done by hand has resulted in making shoes at a fraction of their former labor cost, and in selling them so cheap that now almost every man, woman, and child in the working-classes buys one or two pairs of shoes per year, and wears shoes all the time, whereas formerly each workman bought perhaps one pair of shoes every five years, and went barefoot most of the time, wearing shoes only as a luxury or as a matter of the sternest necessity. In spite of the enormously increased output of shoes per workman, which has come with shoe machinery, the demand for shoes has so increased that there are relatively more men working in the shoe industry now than ever before.


As engineers and managers, we are more intimately acquainted with these facts than any other class in the community, and are therefore best fitted to lead in a movement to combat this fallacious idea by educating not only the workmen but the whole of the country as to the true facts. 

The writer  quotes from  "Shop Management," which it is hoped will explain fully this cause for soldiering:

"This loafing or soldiering proceeds from two causes. First, from the natural instinct and tendency of men to take it easy, which may be called natural soldiering. Second, from more intricate second thought and reasoning caused by their relations with other men, which may be called systematic soldiering."

"There is no question that the tendency of the average man (in all walks of life) is toward working at a slow, easy gait, and that it is only after a good deal of thought and observation on his part or as a result of example, conscience, or external pressure that he takes a more rapid pace." "The natural laziness of men is serious, but by far the greatest evil from which both workmen and employers are suffering is the systematic soldiering." "The greater part of the systematic soldiering, however, is done by the men with the deliberate object of keeping their employers ignorant of how fast work can be done."

"The causes for this are, briefly, that practically all employers determine upon a maximum sum which they feel it is right for each of their classes of employees to earn per day, whether their men work by
the day or piece." "Each workman soon finds out about what this figure is for his particular case, and he also realizes that when his employer is convinced that a man is capable of doing more work than he has done, he will find sooner or later some way of compelling him to do it with little or no increase of pay."


Third. Great gain, both to employers and employees, results from the substitution of scientific for rule-of-thumb methods in even the smallest details of the work of every trade. The enormous saving of time and therefore increase in the output which it is possible to effect through eliminating unnecessary motions and substituting fast for slow and inefficient motions for the men working in any of our trades can be fully realized only after one has personally seen the improvement which results from a thorough motion and time study, made by a competent man.

The one best method of doing a specified motion can be discovered or developed through a scientific study and analysis of all of the methods and implements in use, together with accurate, minute, motion and time study. This involves the gradual substitution of science for rule of thumb throughout the mechanic arts.

4. Underlying Philosophy for the Old Systems of Management

This paper will show that the underlying philosophy of all of the old systems of management in common use makes it imperative that each workman shall be left with the final responsibility for doing his job practically as he thinks best, with comparatively little help and advice from the management. 


In order that the work may be done in accordance with scientific laws, it is necessary that there shall be a far more equal division of the responsibility between the management and the workmen than exists under any of the ordinary types of management. Those in the management must have the  duty to develop the science of each motion and  should also guide and help the workman in working under it.  Managers should assume a much larger share of the responsibility for results than under the current way of managing workmen in factories.

5. Scientific Management - Introduction



Almost every act of the workman should be preceded by one or more preparatory acts of the management which enable him to do his work better and quicker than he otherwise could. And each man should daily be taught by and receive the most friendly help from those who are over him.

This close, intimate, personal cooperation between the management and the men is of the essence of modern scientific or task management.

It will be shown by a series of practical illustrations that, through this friendly cooperation, namely, through sharing equally in every day's burden, all of the great obstacles (above described) to obtaining the maximum output for each man and each machine in the establishment are swept away. The 30 per cent to 100 per cent increase in wages which the workmen are able to earn beyond what they receive under the old type of management, coupled with the daily intimate shoulder to shoulder contact with the management, entirely removes all cause for soldiering. And in a few years, under this system, the workmen have before them the object lesson of seeing that a great increase in the output per man results in giving employment to more men, instead of throwing men out of work, thus completely eradicating the fallacy that a larger output for each man will throw other men out of work.

The theory, or philosophy, of scientific management is just beginning to be understood and its  gradual evolution is taking place for the last thirty years (till 1911).  At least 50,000 workmen in the United States are now employed under this system; and they are receiving from 30 per cent to 100 per cent higher wages daily than are paid to men of similar caliber with whom they are surrounded, while the companies employing them are more prosperous than ever before. In these companies the output, per man and per machine, has on an average been doubled. 

Scientific management fundamentally consists of certain broad general principles, a certain philosophy, which can be applied in many ways.  That these principles are certain to come into general use practically throughout the civilized world, sooner or later, the writer is profoundly convinced, and the sooner they come the better for all the people.

6. THE PRINCIPLES OF SCIENTIFIC MANAGEMENT

Under scientific management the "initiative" of the workmen (that is, their hard work, their good-will, and their ingenuity) is obtained with absolute uniformity and to a greater extent than is possible under the old system; and in addition to this improvement on the part of the men, the managers assume new burdens, new duties, and responsibilities never dreamed of in the past. The managers assume, for instance, the burden of gathering together all of the traditional knowledge which in the past has been possessed by the workmen and then of classifying, tabulating, and reducing this knowledge to rules, laws, and formulae which are immensely helpful to the workmen in doing their daily work. In addition to developing a science in this way, the management take on three other types of duties which involve new and heavy burdens for themselves.

These new duties are grouped under four heads:

First. They develop a science for each element of a man's work, which replaces the old rule-of.-thumb method.

Second. They scientifically select and then train, teach, and develop the workman, whereas in the past he chose his own work and trained himself as best he could.

Third. They heartily cooperate with the men so as to insure all of the work being done in accordance with the principles of the science which has been developed.

Fourth. There is an almost equal division of the work and the responsibility between the management and the workmen. The management take over all work for which they are better fitted than the workmen,
while in the past almost all of the work and the greater part of the responsibility were thrown upon the men.

It is this combination of the initiative of the workmen, coupled with the new types of work done by the management, that makes scientific management so much more efficient than the old plan.


The practical use of scientific data also calls for a room in which to keep the books, records*, etc., and a desk for the planner to work at.



Thus all of the planning which under the old system was done by the workman, as a result of his personal experience, must of necessity under the new system be done by the management in accordance with the laws of the science. It is also clear that in most cases one type of man is needed to plan ahead and an entirely different type to execute the work in a shop of reasonable size. Each act of each mechanic, for example, should be preceded by various preparatory acts done by other men. And all of this involves, as we have said, "an almost equal division of the responsibility and the work between the management and the workman."

To summarize: Under the management of "initiative and incentive" practically the whole problem of production  is "up to the workman," while under scientific management fully one-half of the problem is "up to the management."

Perhaps the most prominent single element in modern scientific management is the task idea. The work of every workman is fully planned out by the management at least one day in advance, and each man receives in most cases complete written instructions, describing in detail the task which he is to accomplish, as well as the means to be used in doing the work. And the work planned in advance in this way constitutes a task which is to be solved, as explained above, not by the workman  alone,   but in almost all cases by the joint effort of the workman and the management. This task specifies not only what is to be done but how it is to be done and the exact time allowed for doing it. And whenever the workman succeeds in doing his task right, and within the time limit specified, he receives an addition of from 30 per cent to 100 per cent to his ordinary wages. These tasks are carefully planned, so that both good and careful work are called for in their performance, but it should be distinctly understood that in no case is the workman called upon to work at a pace which would be injurious to his health. The task is always so regulated that the man who is well suited to his job will thrive while working at this rate during a long term of years and grow happier and more prosperous, instead of being overworked. Scientific management consists very largely in preparing for and carrying out these tasks.

The writer's hope of carrying conviction of the readers of this paper rests upon demonstrating the tremendous force and effect of these four principles  through a series of practical illustrations. 

7. Illustrations of Success of Scientific Management - - Pig Iron Handling

The first illustration is that of handling pig iron, and this work is chosen because it is typical of perhaps the crudest and most elementary form of labor which is performed by man. This work is done by men with no other implements than their hands. The pig-iron handler stoops down, picks up a pig weighing about 92 pounds, walks for a few feet or yards and then drops it on to the ground or upon a pile. 

Yet it will be shown that the science of handling pig iron also requires data collection and intelligent hypothesis building to develop.  You require man better educated to develop science to do it.  In almost all of the mechanic arts the science which underlies each workman's act is so great and amounts to so much that the workman who is best suited actually to do the work cannot be expected to develop this science without managers putting in their knowledge and skill to work in cooperation with workmen to develop science.  After showing the applications of four elements (principles) in the handling of pig iron, several illustrations will be given of their application to different kinds of work in the field of the mechanic arts (human effort), at intervals in a rising scale, beginning with the simplest and ending with the more intricate forms of labor.

One of the first pieces of work undertaken by us, when the writer started to introduce scientific management into the Bethlehem Steel Company, was to handle pig iron on task work. The Bethlehem Steel Company had five blast furnaces, the product of which had been handled by a pig-iron gang for many years. This gang, at this time, consisted of about 75 men. They were good, average pig-iron handlers, were under an excellent foreman who himself had been a pig-iron handler, and the work was done, on the whole, about as fast and as cheaply as it was anywhere else at that time. We found that this gang were loading on the average about 12 and a half long tons per man per day. We were surprised to find, after studying the matter, that a first-class pig-iron handler ought to handle between 47, and 48 long tons per day, instead of 12 and a half tons. This task seemed to us so very large that we were obliged to go over our work several times before we were absolutely sure that we were right. Once we were sure, however, that 47 tons was a proper day's work for a first-class pig-iron handler, the task which faced us as managers under the modern scientific plan was clearly before us. It was our duty to see that the 80,000 tons of pig iron was loaded on to the cars at the rate of 47 tons per man per day, in place of 12 and a half tons, at which rate the work was then being done. And it was further our duty to see that this work was done without bringing on a strike among the men, without any quarrel with the men, and to see that the men were happier and better contented when loading at the new rate of 47 tons than they were when loading at the old rate of 12 and a half tons.

Our first step was the scientific selection of the workman. In dealing with workmen under this type of management, it is an inflexible rule to talk to and deal with only one man at a time, since each workman has his own special abilities and limitations, and since we are not dealing with men in masses, but are trying to develop each individual man to his highest state of efficiency and prosperity. Our first step was to find the proper workman to begin with. We therefore carefully watched and studied these 75 men for three or four days, at the end of which time we had picked out four men who appeared to be physically able to handle pig iron at the rate of 47 tons per day. 

He was offered a higher payment of $1.85 for following instructions and loading a pile of 47 tons. He questioned whether he will get  $1.85 for loading dot pig iron on dot car to-morrow and everyday?" He was promised accordingly.  Schmidt (a fictitious name) started to work, and all day long, and at regular intervals, was told by the man who stood over him with a watch, On the first day, at half-past five in the afternoon had his 47 and a half tons loaded on the car. And he practically never failed to work at this pace and do the task that was set him during the three years that the writer was at Bethlehem. And throughout this time he averaged a little more than $1.85 per day, whereas before he had never received over $1.15 per day, which was the ruling rate of wages at that time in Bethlehem. That is, he received 60 per cent. higher wages than were paid to other men who were not working on task work. One man after another was picked out and trained to handle pig iron at the rate of 47 and a half tons per day until all of the pig iron was handled at this rate, and the men were receiving 60 per cent. more wages than other workmen around them.

The writer has given above a brief description of three of the four elements which constitute the essence of scientific management: first, the careful selection of the workman, and, second and third, the method of first inducing and then training and helping the workman to work according to the scientific method. Nothing has as yet been said about the science of handling pig iron. But there is a science of handling pig iron. 

The law is confined to that class of work in which the limit of a man's capacity is reached because he is tired out. It is the law of heavy laboring, corresponding to the work of the cart horse, rather than that of the trotter. Practically all such work consists of a heavy pull or a push on the man's arms, that is, the man's strength is exerted by either lifting or pushing something which he grasps in his hands. And the law is that for each given pull or push on the man's arms it is possible for the workman to be under load for only a definite percentage of the day. For example, when pig iron is being handled (each pig weighing 92 pounds), a first-class workman can only be under load 43 per cent of the day. He must be entirely free from load during 57 per cent of the day.

And as the load becomes lighter, the percentage of the day under which the man can remain under load increases. So that, if the workman is handling a half-pig, weighing 46 pounds, he can then be under load 58 per cent of the day, and only has to rest during 42 per cent. As the weight grows lighter the man can remain under load during a larger and larger percentage of the day, until finally a load is reached which he can carry in his hands all day long without being tired out. When that point has been arrived at this law ceases to be useful as a guide to a laborer's endurance, and some other law must be found which indicates the man's capacity for work.

The writer trusts that it is now clear that even in the case of the most elementary form of labor that is known, there is a science, and that when the man best suited to this class of work has been carefully selected, when the science of doing the work has been developed, and when the carefully selected man has been trained to work in accordance with this science, the results obtained must of necessity be overwhelmingly greater than those which are possible under the plan of "initiative and incentive."

Although the reader may be convinced that there is a certain science back of the handling of pig iron, still it is more than likely that he is still skeptical as to the existence of a science for doing other kinds of laboring. One of the important objects of this paper is to convince its readers that science can be developed for all acts of mechanics or workmen and the effort delivers value. With the hope of fully convincing the reader of this fact, therefore, the writer proposes to give several more simple illustrations from among the thousands which are at hand.

Illustration of Shoveling


For example, the average man would question whether there is much of any science in the work of shoveling. For a first-class shoveler there is a given shovel load at which he will do his biggest day's work. What is this shovel load? Will a first-class man do more work per day with a shovel load of 5 pounds, 10 pounds, 15 pounds, 20, 25, 30, or 40 pounds? Now this is a question which can be answered only through carefully made experiments. By first selecting two or three first-class shovelers, and paying them extra wages for doing trustworthy work, and then gradually varying the shovel load and having
all the conditions accompanying the work carefully observed for several weeks by men who were used to experimenting, it was found that a first-class man would do his biggest day's work with a shovel load of about 21 pounds. For instance, that this man would shovel a larger tonnage per day with a 21-pound load than with a 24-pound load or than with an 18-pound load on his shovel. It is, of course, evident that no shoveler can always take a load of exactly 21 pounds on his shovel, but nevertheless, although his load may vary 3 or 4 pounds one way or the other, either below or above the 21 pounds, he will do his biggest day's work when his average for the day is about 21 pounds.

At the works of the Bethlehem Steel Company, for example, as a result of this law, instead of allowing each shoveler to select and own his own shovel, it became necessary to provide some 8 to 10 different kinds of shovels, etc., each one appropriate to handling a given type of material not only so as to enable the men to handle an average load of 21 pounds, but also to adapt the shovel to several other requirements which become perfectly evident when this work is studied as a science. 

Briefly to illustrate some of the other elements which go to make up the science of shoveling, thousands of stop-watch observations were made to study just how quickly a laborer, provided in each case with the proper type of shovel, can push his shovel into the pile of materials and then draw it out properly loaded. These observations were made first when pushing the shovel into the body of the pile. Next when shoveling on a dirt bottom, that is, at the outside edge of the pile, and next with a wooden bottom, and finally with an iron bottom. Again a similar accurate time study was made of the time required to swing the shovel backward and then throw the load for a given horizontal distance, accompanied by a given height. This time study was made for various combinations of distance and height. With data of this sort before him, coupled with the law of endurance described in the case of the pig-iron handlers, it is evident that the man who is directing shovelers can first teach them the exact methods which should be employed to use their strength to the very best advantage, and can then assign them daily tasks which are so just that the workman can each day be sure of earning the large bonus which is paid whenever he successfully performs this task.


8. Background for Development of Scientific Management - -Midvale Steel Company Machine Shop

Taylor at Midvale Steel  Company Machine Shop


The writer came into the machine-shop of the Midvale Steel Company in 1878, after having served an apprenticeship as a pattern-maker and as a machinist. 

Almost all of the work of this shop had been done on piece work for several years. As was usual then, and in fact as is still usual in most of the shops in this country, the shop was really run by the workmen, and not by the bosses. 

As soon as the writer was made gang-boss,  he started to do whatever he could to get a fair day's work out of the lathes. This immediately started a war; in most cases a friendly war, because the men who were under him were his personal friends, but none the less a war. In a war of this kind the workmen have one expedient which is usually effective. They use their ingenuity to contrive various ways in which the machines which they are running are broken or damaged--apparently by accident, or in the regular course of work--and this they always lay at the door of the foreman, who has forced them to drive the machine so hard that it is overstrained and is being ruined. The writer had an effective answer to this Vandalism on the part of the men, namely: "There will be no more accidents to the machines in this shop. If any part of a machine is broken the man in charge of it must pay at least a part of the cost of its repair, and the fines collected in this way will all be handed over to the mutual beneficial association to help care for sick workmen." This soon stopped the willful breaking of machines. After about three years of this kind of struggling, the output of the machines had been materially increased, in many cases doubled, and as a result the writer had been promoted from one gang-boss-ship to another until he became foreman of the shop.  Soon after being made foreman,  he decided to make a determined effort to in some way change the system of management, so that the interests of the workmen and the management should become the same, instead of antagonistic. This resulted, some three years later, in the starting of the type of management which is described in papers presented to the American Society of Mechanical Engineers entitled "A Piece-Rate System" and "Shop Management."

In preparation for this system the writer realized that the greatest obstacle to harmonious cooperation between the workmen and the management lay in the ignorance of the management as to what really constitutes a proper day's work for a workman. He fully realized that although he was foreman of the shop, the combined knowledge and skill of the workmen who were under him was certainly ten times as great as his own. He therefore obtained the permission of Mr. William Sellers, who was at that time the President of the Midvale Steel Company, to spend some money in a careful, scientific study of the time required to do various kinds of work.

A large amount of very valuable data had been obtained.  The problem of developing this law from the accumulated facts was therefore handed over to Mr. Carl G. Barth, who is a better mathematician than any of the rest of us, and we decided to investigate the problem in a new way, by graphically representing each element of the work through plotting curves, which should give us, as it were, a bird's-eye view of every element. In a comparatively short time Mr. Barth had discovered the law governing the tiring effect of heavy labor on a first-class man. 

9. Elaborate Planning Organization - Need and Utility

All of this requires the kindly cooperation of the management, and involves a much more elaborate organization and system than the old-fashioned herding of men in large gangs. This organization consisted, in this case, of one set of men, who were engaged in the development of the science of laboring through time study, such as has been described above; another set of men, mostly skilled laborers themselves, who were teachers, and who helped and guided the men in their work; another set of tool-room men who provided them with the proper implements and kept them in perfect order, and another set of clerks who planned the work well in advance, moved the men with the least loss of time from one place to another, and properly recorded each man's earnings, etc. And this furnishes an elementary illustration of what has been referred to as cooperation between the management and the
workmen.

Elaborate Planning Organization


The question which naturally presents itself is whether an elaborate organization of this sort can be made to pay for itself; whether such an organization is not top-heavy. This question will best be answered by a statement of the results of the third year of working under this plan.


                                                         Old Plan                           New Plan Task Work
  The number of yard laborers
  was reduced from between         400 & 600                    down to about 140
  Average number of tons per
  man per day                                        16                                   59
  Average earnings per man
  per day                                             $1.15                               $1.88
  Average cost of handling a
  ton of 2240 lbs                                 $0.072                             $0.033

And in computing the low cost of $0.033 per ton, the office and tool-room expenses, and the wages of all labor superintendents, foremen, clerks, time-study men, etc., are included.

During this year the total saving of the new plan over the old amounted to $36,417.69, and during the six months following, when all of the work of the yard was on task work, the saving was at the rate of between $75,000 and $80,000 per year.

And this presents a very simple though effective illustration of what is meant by the words "prosperity for the employee, coupled with prosperity for the employer," the two principal objects of management. It is evident also that this result has been brought about by the application of the four fundamental principles of scientific management.


10. Illustrations of Success of Scientific Management - Bricklaying Improvement by Gilbreth

Illustration of Human Effort Productivity Improvement - Bricklaying Improvement by Gilbreth

Appreciation of Gilbreth's Motion Study  by Taylor


Bricklaying is one of the oldest of our trades.

For hundreds of years there has been little or no improvement made in the implements and materials used in this trade, nor in fact in the method of laying bricks. In spite of the millions of men who have practiced this trade, no great improvement has been evolved for many generations. Here, then, at least one would expect to find but little gain possible through scientific analysis and study. Mr. Frank B. Gilbreth, a member of our Society, who had himself studied bricklaying in his youth, became interested in the principles of scientific management, and decided to apply them to the art of bricklaying. He made an intensely interesting analysis and study of each movement of the bricklayer, and one after another eliminated all unnecessary movements and substituted fast for slow motions. He experimented with every minute element which in any way affects the speed and the tiring of the bricklayer.

Through all of this minute study of the motions to be made by the bricklayer in laying bricks under standard conditions, Mr. Gilbreth has reduced his movements from eighteen motions per brick to five, and even in one case to as low as two motions per brick

An analysis of the expedients used by Mr. Gilbreth in reducing the motions of his bricklayers from eighteen to five shows that this improvement has been made in three different ways:

First. He has entirely dispensed with certain movements which the bricklayers in the past believed were necessary, but which a careful study and trial on his part have shown to be useless.

Second. He has introduced simple apparatus, such as his adjustable scaffold and his packets for holding the bricks, by means of which, with a very small amount of cooperation from a cheap laborer, he entirely eliminates a lot of tiresome and time-consuming motions which are necessary for the brick-layer who lacks the scaffold and the packet.

Third. He teaches his bricklayers to make simple motions with both hands at the same time, where before they completed a motion with the right hand and followed it later with one from the left hand.

These three kinds of improvements are typical of the ways in which needless motions can be entirely eliminated and quicker types of movements substituted for slow movements when scientific motion study, as Mr. Gilbreth calls his analysis, time study, as the writer has called similar work, are, applied in any trade.

Mr. Gilbreth's method of bricklaying furnishes a simple illustration of true and effective cooperation. Not the type of cooperation in which a mass of workmen on one side together cooperate with the management; but that in which several men in the management (each one in his own particular way) help each workman individually, on the one hand, by studying his needs and his shortcomings and teaching him better and quicker methods, and, on the other hand, by seeing that all other workmen with whom he comes in contact help and cooperate with him by doing their part of the work right and fast.

The writer has gone thus fully into Mr. Gilbreth's method in order that it may be perfectly clear that his success has been due to the use of the four elements which constitute the essence of scientific management.

First. The development (by the management, not the workman) of the science of bricklaying, with rigid rules for each motion of every man, and the perfection and standardization of all implements and working conditions.

Second. The careful selection and subsequent training of the bricklayers into first-class men, and the elimination of all men who refuse to or are unable to adopt the best methods.

Third. Bringing the first-class bricklayer and the science of bricklaying together, through the constant help and watchfulness of the management, and through paying each man a large daily bonus for working fast and doing what he is told to do.

Fourth. An almost equal division of the work and responsibility between the workman and the management. All day long the management work almost side by side with the men, helping, encouraging, and smoothing the way for them, while in the past they stood one side, gave the men but little help, and threw on to them almost the entire responsibility as to methods, implements, speed, and harmonious cooperation.

Of these four elements, the first (the development of the science of bricklaying) is the most interesting and spectacular. Each of the three others is, however, quite as necessary for success.

It must not be forgotten that back of all this, and directing it, there must be the optimistic, determined, and hard-working leader who can wait patiently as well as work.


11. Illustrations of Success of Scientific Management - Bicycle Balls Inspection Example

Scientific selection of the workman - Bicycle Balls Inspection Example


In most cases (particularly when the work to be done is intricate in its nature) the "development of the science" is the most important of the four great elements of the new management. There are instances, however, in which the "scientific selection of the workman" counts for more than anything else.

A case of this type is well illustrated in the very simple though unusual work of inspecting bicycle balls.

Among the twenty or more operations used in making steel balls, perhaps the most important was that of inspecting them after final polishing so as to remove all fire-cracked or otherwise imperfect balls before boxing. One hundred and twenty or more girls who were inspecting the balls were "old bands" and skilled at their jobs. 
Their work consisted briefly in placing a row of small polished steel balls on the back of the left hand, in the crease between two of the fingers pressed together, and while they were rolled over and over, they were minutely examined in a strong light, and with the aid of a magnet held in the right hand, the defective balls were picked out and thrown into especial boxes. Four kinds of defects were looked for-dented, soft, scratched, and fire-cracked--and they were mostly so minute as to be invisible to an eye not especially trained to this work. It required the closest attention and concentration, so that the nervous tension of the inspectors was considerable, in spite of the fact that they were comfortably seated and were not physically tired.


The change from the old to the scientific method in this department was made under the direction of Mr. Sanford E. Thompson, perhaps the most experienced man in motion and time study in this country, under the general superintendence of Mr. H. L. Gantt.

In the Physiological departments of our universities experiments are regularly conducted to determine what is known as the "personal coefficient" of the man tested. This is done by suddenly bringing some object, the letter A or B for instance, within the range of vision of the subject, who, the instant he recognizes the letter has to do some definite thing, such as to press a particular electric button. The time which elapses from the instant the letter comes in view until the subject presses the button is accurately recorded by a delicate scientific instrument.

This test shows conclusively that there is a great difference in the "personal coefficient" of different men. Some individuals are born with unusually quick powers of perception accompanied by quick responsive action. With some the message is almost instantly transmitted from the eye to the brain, and the brain equally quickly responds by sending the proper message to the hand.

Men of this type are said to have a low "personal coefficient," while those of slow perception and slow action have a high "personal coefficient."

Mr. Thompson soon recognized that the quality most needed for bicycle ball inspectors was a low personal coefficient. 


Guarding Against Deterioration of Quality Due to Increase in Output


One of the dangers to be guarded against, when the pay of the man or woman is made in any way to depend on the quantity of the work done, is that in the effort to increase the quantity the quality is apt to deteriorate.

It is necessary in almost all cases, therefore, to take definite steps to insure against any falling off in quality before moving in any way towards an increase in quantity.

In the work of these particular girls quality was the very essence. They were engaged in picking out all defective balls.

The first step, therefore, was to make it impossible for them to slight their work without being, found out. This was accomplished through what is known as over-inspection. Each one of four of the most trust-worthy girls was given each day a lot of balls to inspect which had been examined the day before by one of the regular inspectors; the number identifying the lot to be over-inspected having been changed by the foreman so that none of the over-inspectors knew whose work they were examining. In addition to this one of the lots inspected by the four over-inspectors was examined on the following day by the chief inspector, selected on account of her especial accuracy and integrity.

An effective expedient was adopted for checking the honesty and accuracy of the over-inspection. Every two or three days a lot of balls was especially prepared by the foreman, who counted out a definite number of perfect balls, and added a recorded number of defective balls of each kind. Neither the inspectors nor the over-inspectors had any means of distinguishing this prepared lot from the regular commercial lots. And in this way all temptation to slight their work or make false returns
was removed.

More Measures to Improve Productivity


And it is only after this stage in the reorganization is reached, when the girls have been properly selected and on the one hand such precautions have been taken as to guard against the possibility of over-driving them, that the final step should be taken which insures them what they most want, namely, high wages, and the employers what they most want, namely, the maximum output and best quality of work, -which means a low labor cost.

This step is to give each girl each day a carefully measured task which demands a full day's work from a competent operative, and also to give her a large premium or bonus whenever she accomplishes this task.

This was done in this case through establishing what is known as differential rate piece work.* Under this system the pay of each girl was increased in proportion to the quantity of her output and also still more in proportion to the accuracy of her work. As will be shown later, the differential rate (the lots inspected by the over-inspectors forming the basis for the differential) resulted in a large gain in the quantity of work done and at the same time in a marked improvement in the quality. Before they finally worked to the best advantage it was found to be necessary to measure the output of each girl as often as once every hour, and to send a teacher to each individual who was found to be falling behind to find what was wrong, to straighten her out, and to encourage and help her to catch up.

There is a general principle back of this which should be appreciated by all of those who are especially interested in the management of men.

Importance of Quick Rewards


A reward, if it is to be effective in stimulating men to do their best work, must come soon after the work has been done. But few men are able to look forward for more than a week or perhaps at most a month, and work hard for a reward which they are to receive at the end of this time.

To come back to the girls inspecting bicycle balls, however, the final outcome of all the changes was that thirty-five girls did the work formerly done by one hundred and twenty. And that the accuracy of the work at the higher speed was two-thirds greater than at the former slow speed.

These good results were brought about by many changes which substituted favorable for unfavorable working conditions. It should be appreciated, however, that the one element which did more than all of the others was, the careful selection of girls with quick perception to replace those whose perceptions were slow--(the substitution of girls with a low personal coefficient for those whose personal coefficient was high)--the scientific selection of the workers.

12. Scientific Management in Machine Shop

Is there a need to develop science and scientific laws and techniques based on them for work on machines by machinists?


The illustrations (given in earlier chapters/sections) have thus far been purposely confined to the more elementary types of work, so that a very strong doubt must still remain as to whether this kind of cooperation is desirable in the case of more intelligent mechanics, that is, in the case of men who are more capable of generalization, and who would therefore be more likely, of their own volition, to choose the more scientific and better methods.


Doubling of Production from a Machine through introduction of scientific management


A number of years ago a company employing about three hundred men, which had been manufacturing the same machine for ten to fifteen years, sent for us to report as to whether any gain could be made through the introduction of scientific management. The superintendent was distinctly displeased when told that through the adoption of task management the output, with the same number of men and machines, could be more than doubled.  He, however, readily assented to the proposition that he should select any one of the machines whose output he considered as representing the average of the shop, and that we should then demonstrate on this machine that through scientific methods its output could be more than doubled.


Preparation for productivity improvement through scientific management.


The machine selected by him It had been run for ten or twelve years past by a first-class mechanic who was more than equal in his ability to the average workmen in the establishment. 

A careful record was therefore made, in the presence of both parties, of the time actually taken in finishing each of the parts which this man worked upon. The total time required by him to finish each piece, as well as the exact speeds and feeds which he took, were noted and a record was kept of the time which he took in setting the work in the machine and removing it. After obtaining in this way a statement of what represented a fair average of the work done in the shop, we applied to this one machine the principles of scientific management.

Machine Effort Industrial Engineering


By means of four quite elaborate slide-rules, which have been especially made for the purpose of determining the all-round capacity of metal-cutting machines, a careful analysis was made of every element of this machine in its relation to the work in hand. Its Pulling power at its various speeds, its feeding capacity, and its proper speeds were determined by means of the slide-rules, and changes were then made in the countershaft and driving pulleys so as to run it at its proper speed. Tools, made of high-speed steel, and of the proper shapes, were properly dressed, treated, and ground. 

A large special slide-rule was then made, by means of which the exact speeds and feeds were indicated at which each kind of work could be done in the shortest possible time in this particular lathe. After preparing in this way so that the workman should work according to the new method, one after another, pieces of work were finished in the lathe, corresponding to the work which had been done in our preliminary trials, and the gain in time made through running the machine according to scientific principles ranged from two and one-half times the speed in the slowest instance to nine times the speed in the highest.

Human Effort Industrial Engineering - Scientific man work and change in mental attitude


The physical improvements in the machines necessary to insure large gains, and the motion study followed by minute study with a stop-watch of the time in which each workman should do his work, can be made comparatively quickly.

Within three years, however, in this shop, the output had been more than doubled per man and per machine. The men had been carefully selected and in almost all cases promoted from a lower to a higher order of work, and so instructed by their teachers (the functional foremen) that they were able to earn higher wages than ever before. The average increase in the daily earnings of each man was about 35 per cent., while, at the same time, the sum total of the wages paid for doing a given amount of work was lower than before. This increase in the speed of doing the work, of course, involved a substitution of the quickest hand methods for the old independent rule-of-thumb methods, and an elaborate analysis of the hand work done by each man. (By hand work is meant such work as depends upon the manual dexterity and speed of a workman, and which is independent of the work done by the machine.) The time saved by scientific hand work was in many cases greater even than that saved in machine-work.



When men, whose education has given them the habit of generalizing and everywhere looking for laws, find themselves confronted with a multitude of problems, such as exist in every trade and which have a general similarity one to another, it is inevitable that they should try to gather these problems into certain logical groups, and then search for some general laws or rules to guide them in their solution.

The philosophy of scientific management places their solution in the hands of the management. Under scientific management, on the other hand, it becomes the duty and also the pleasure of those who are engaged in the management not only to develop laws to replace rule of thumb, but also to teach impartially all of the workmen who are under them the quickest ways of working. The useful results obtained from these laws are always so great that any company can well afford to pay for the time and the experiments needed to develop them. Thus under scientific management exact scientific knowledge and methods are everywhere, sooner or later, sure to replace rule of thumb. The development of the art or science of cutting metals is an apt illustration of this fact. In the fall of 1880, about the time that the writer started to make the experiments above referred to, to determine what constitutes a proper day's work for a laborer, he also obtained the permission of Mr. William Sellers, the President of the Midvale Steel Company, to make a series of experiments to determine what angles and shapes of tools were the best for cutting steel, and also to try to determine the proper cutting speed for steel. Experiments in this field were carried on, with occasional interruption, through a period of about 26 years, in the course of which ten different experimental machines were especially fitted up to do this work. Between 30,000 and 50,000 experiments were carefully recorded, and many other experiments were made, of which no record was kept. In studying these laws more than 800,000 pounds of steel and iron was cut up into chips with the experimental tools, and it is estimated that from $150,000 to $200,000 was spent in the investigation.

Work of this character is intensely interesting to any one who has any love for scientific research. For the purpose of this paper, however, it should be fully appreciated that the motive power which kept these experiments going through many years, and which supplied the money and the opportunity for their accomplishment, was not an abstract search after scientific knowledge, but was the very practical fact that we lacked the exact information which was needed every day, in order to help our machinists to do their work in the best way and in the quickest time.
 







It should be apparent why the high-class mechanic, who is called upon to do a great variety of work from day to day, is even less able to compete with this science. The high-class mechanic who does a different kind of work each day, in order to do each job in the quickest time, would need, in addition to a thorough knowledge of the art of cutting metals, a vast knowledge and experience in the quickest way of doing each kind of hand workAnd the reader, by calling to mind the gain which was made by Mr. Gilbreth through his motion and time study in laying bricks, will appreciate the great possibilities for quicker methods of doing all kinds of hand work which lie before every tradesman after he has the help which comes from a scientific motion and time study of his work.

For nearly thirty years past, time-study men connected with the management of machine-shops have been devoting their whole time to a scientific motion study, followed by accurate time study, with a stop-watch, of all of the elements connected with the machinist's work. When, therefore, the teachers, who form one section of the management, and who are cooperating with the working men, are in possession both of the science of cutting metals and of the equally elaborate motion-study and time-study science connected with this work, it is not difficult to appreciate why even the highest class mechanic is unable to do his best work without constant daily assistance from his teachers. And if this fact has been made clear to the reader, one of the important objects in writing this paper will have been realized.

It is hoped that the illustrations which have been given make it apparent why scientific management must inevitably in all cases produce overwhelmingly greater results, both for the company and its employees, than can be obtained with the management of "initiative and incentive." And it should also be clear that these results have been attained, not through a marked superiority in the mechanism of one type of management over the mechanism of another, but rather through the substitution of one set of underlying principles for a totally different set of principles, by the substitution of one philosophy for another philosophy in industrial management.

Philosophy of Scientific Management (Industrial Engineering)



To repeat them throughout all of these illustrations, it will be seen that the useful results have hinged mainly upon (1) the substitution of a science for the individual judgment of the workman; (2) the scientific selection and development of the workman, after each man has been studied, taught, and trained, and one may say experimented with, instead of allowing the workmen to select themselves and develop in a haphazard way; and (3) the intimate cooperation of the management with the workmen, so that they together do the work in accordance with the scientific laws which have been developed, instead of leaving the solution of each problem in the hands of the individual workman. In applying these new principles, in place of the old individual effort of each workman, both sides share almost equally in the daily performance of each task, the management doing that part of the work for which they are best fitted, and the workmen the balance.

13. Development of Science in Mechanic Arts


The Science of Human Motions


In most trades, the science is developed through a comparatively simple analysis and time study of the movements required by the workmen to do some small part of his work, and this study is usually made by a man equipped merely with a stop-watch and a properly ruled notebook. Hundreds of these "time-study men" are now engaged in developing elementary scientific knowledge.  Even the motion study of Mr. Gilbreth in bricklaying involves a much more elaborate investigation than that which occurs in most cases. The general steps to be taken in developing a simple law of this class are as follows:

First. Find, say, 10 or 15 different men (preferably in as many separate establishments and different parts of the country) who are especially skillful in doing the particular work to be analyzed.

Second. Study the exact series of elementary operations or motions which each of these men uses in doing the work which is being investigated, as well as the implements each man uses.

Third. Study with a stop-watch the time required to make each of these elementary movements and then select the quickest way of doing each element of the work.

Fourth. Eliminate all false movements, slow movements, and useless movements.

Fifth. After doing away with all unnecessary movements, collect into one series the quickest and best movements as well as the best implements.

This one new method, involving that series of motions which can be made quickest and best, is then substituted in place of the ten or fifteen inferior series which were formerly in use. This best method becomes standard, and remains standard, to be taught first to the teachers (or functional foremen) and by them to every workman in the establishment until it is superseded by a quicker and better series of movements. In this simple way one element after another of the science is developed.

In the same way each type of implement used in a trade is studied. Scientific management requires, first, a careful investigation of each of the many modifications of the same implement, developed by various workmen;  and second, after a time study has been made of the speed attainable with each of these implements, that the good points of several of them shall be united in a single standard implement, which will enable the workman to work faster and with greater ease than he could before. This one implement, then, is adopted as standard in place of the many different kinds before in use, and it remains standard for all workmen to use until superseded by an implement which has been shown, through motion and time study, to be still better.

With this explanation it will be seen that the development of a science to replace rule of thumb is in most cases by no means a formidable undertaking, and that it can be accomplished by managers; but that, on the other hand, the successful use of even the simplest improvement of this kind calls for records, system, and cooperation where in the past existed only individual effort.


14. Study of Motives of Men

Accurate Study of the Motives Which Influence Men. 


There is another type of scientific investigation which has been referred to several times in this paper, and which should receive special attention, namely, the accurate study of the motives which influence men. At first it may appear that this is a matter for individual observation and judgment, and is not a proper subject for exact scientific experiments. It is true that the laws which result from experiments of this class, owing to the fact that the very complex organism--the human being--is being experimented with, are subject to a larger number of exceptions than is the case with laws relating to material things. And yet laws of this kind, which apply to a large majority of men, unquestionably exist, and when clearly defined are of great value as a guide in dealing with men. In developing these laws, accurate, carefully planned and executed experiments, extending through a term of years, have been made, similar in a general way to the experiments upon various other elements which have been referred to in this paper. Perhaps the most important law belonging to this class, in its relation to scientific management, is the effect which the task idea has upon the efficiency of the workman. This, in fact, has become such an important element of the mechanism of scientific management, that by a great number of people scientific management has come to be known as "task management."

These two elements, the task and the bonus (which, as has been pointed out in previous papers, can be applied in several ways), constitute two of the most important elements of the mechanism of scientific management. They are especially important from the fact that they are, as it were, a climax, demanding before they can be used almost all of the other elements of the mechanism; such as a planning department, accurate time study, standardization of methods and implements, a routing system, the training of functional foremen or teachers, and in many cases instruction cards slide-rules, etc. 

The necessity for systematically teaching workmen how to work to the best advantage has been several times referred to. Under functional management, the old-fashioned single foreman is superseded by eight different men, each one of whom has his own special duties, and these men, acting as the agents for the planning department  are the expert teachers, who are at all times in the shop, helping, and directing the workmen. Being each one chosen for his knowledge and personal skill in his specialty, they are able not only to tell the workman what he should do, but in case of necessity they do the work themselves in the presence of the workman, so as to show him not only the best but also the quickest methods.

One of these teachers (called the inspector) sees to it that he understands the drawings and instructions for doing the work. He teaches him how to do work of the right quality; how to make it fine and exact where it should be fine, and rough and quick where accuracy is not required,--the one being just as important for success as the other. The second teacher (the gang boss) shows him how to set up the job in his machine, and teaches him to make all of his personal motions in the quickest and best way. The third (the speed boss) sees that the machine is run at the best speed and that the proper tool is used in the particular way which will enable the machine to finish its product in the shortest possible time. In addition to the assistance given by these teachers, the workman receives orders and help from four other men; from the "repair boss" as to the adjustment, cleanliness, and general care of his machine, belting, etc.; from the "time clerk," as to everything relating to his pay and to proper written reports and returns; from the "route clerk," as to the order in which he does his work and as to the movement of the work from one part of the shop to another; and, in case a workman gets into any trouble with any of his various bosses, the "disciplinarian" interviews him.


Encourage Workmen to Suggest Improvements in Methods and Implements


It may seem that with scientific management there is not the same incentive for the workman to use his ingenuity in devising new and better methods of doing the work, as well as in improving his implements, that there is with the old type of management. It is true that with scientific management the workman is not allowed to use whatever implements and methods he sees fit in the daily practice of his work. Every encouragement, however, should be given him to suggest improvements, both in methods and in implements. And whenever a workman proposes an improvement, it should be the policy of the management to make a careful analysis of the new method, and if necessary conduct a series of experiments to determine accurately the relative merit of the new suggestion and of the old standard. And whenever the new method is found to be markedly superior to the old, it should be adopted as the standard for the whole establishment. The workman should be given the full credit for the improvement, and should be paid a cash premium as a reward for his ingenuity. In this way the true initiative of the workmen is better attained under scientific management than under the old individual plan.


15. Scientific management in its essence

The mechanism of management must not be mistaken for its essence. As elements of this mechanism may be cited:

Time study, with the implements and methods for properly making it.

Functional or divided foremanship and its superiority to the old-fashioned single foreman.

The standardization of all tools and implements used in the trades, and also of the acts or movements of workmen for each class of work.

The desirability of a planning room or department.

The "exception principle" in management.

The use of slide-rules and similar timesaving implements.

Instruction cards for the workman.

The task idea in management, accompanied by a large bonus for the successful performance of the task.

The "differential rate."

Mnemonic systems for classifying manufactured products as well as implements used in manufacturing.

A routing system.

Modern cost system, etc., etc.

These are, however, merely the elements or details of the mechanism of management. Scientific management, in its essence, consists of a certain philosophy, which results, as before stated, in a combination of the four great underlying principles of management:*

[*Footnote: First. The development of a true science.
Second. The scientific selection of the workman.
Third. His scientific education and development.
Fourth. Intimate friendly cooperation between the management and the men.]

When, however the elements of this mechanism, such as time study, functional foremanship etc., are used without being accompanied by the true philosophy of management, the results are in many cases disastrous. And, unfortunately, even when men who are thoroughly in sympathy with the principles of scientific management undertake to change too rapidly from the old type to the new, without heeding the warnings of those who have had years of experience in making this change, they frequently meet with serious troubles, and sometimes with strikes, followed by failure.

The writer, in his paper on "Shop Management," has called especial attention to the risks which managers run in attempting to change rapidly from the old to the new management in many cases. The physical changes which are needed, the actual time study which has to be made, the standardization of all implements connected with the work, the necessity for individually studying each machine and placing it in perfect order, all take time, but the faster these elements of the work are studied and improved, the better for the undertaking. On the other hand, the really great problem involved in a change from the management of "initiative and incentive" to scientific management consists in a complete revolution in the mental attitude and the habits of all of those engaged in the management, as well of the workmen. And this change can be brought about only gradually and through the presentation of many object-lessons to the workman, which, together with the teaching which he receives, thoroughly convince him of the superiority of the new over the old way of doing the work. This change in the mental attitude of the workman imperatively demands time. It is impossible to hurry it beyond a certain speed. The writer has over and over again warned those who contemplated making this change that it was a matter, even in a simple establishment, of from two to three years, and that in some cases it requires from four to five years.

The first few changes which affect the workmen should be made exceedingly slowly, and only one workman at a time should be dealt with at the start. Until this single man has been thoroughly convinced that a great gain has come to him from the new method, no further change should be made. Then one man after another should be tactfully changed over. After passing the point at which from one.-fourth to one-third of the men in the employ of the company have been changed from the old to the new, very rapid progress can be made, because at about this time there is, generally, a complete revolution in the public opinion of the whole establishment and practically all of the workmen who are working under the old system become desirous to share in the benefits which they see have been received by those working under the new plan.

Inasmuch as the writer has personally retired from the business of introducing this system of management (that is, from all work done in return for any money compensation), he does not hesitate again to emphasize the fact that those companies are indeed fortunate who can secure the services of experts who have had the necessary practical experience in introducing scientific management, and who have made a special study of its principles. It is not enough that a man should have been a manager in an establishment which is run under the new principles. The man who undertakes to direct the steps to be taken in changing from the old to the new (particularly in any establishment doing elaborate work) must have had personal experience in overcoming the especial difficulties which are always met with, and which are peculiar to this period of transition. It is for this reason that the writer expects to devote the rest of his life chiefly to trying to help those who wish to take up this work as their profession, and to advising the managers and owners of companies in general as to the steps which they should take in making this change.

They are some energetic men who evidently believed that by using much of the mechanism of scientific management, in combination with the principles of the management of "initiative and incentive," instead of with these principles of scientific management, that they could do, in a year or two, what had been proved in the past to require at least double this time. The knowledge obtained from accurate time study, for example, is a powerful implement, and can be used, in one case to promote harmony between the workmen and the management, by gradually educating, training, and leading the workmen into new and better methods of doing the work, or, in the other case, it may be used more or less as a club to drive the workmen into doing a larger day's work for approximately the same pay that they received in the past. Unfortunately the men who had charge of this work did not take the time and the trouble required to train functional foremen, or teachers, who were fitted gradually to lead and educate the workmen. They attempted, through the old-style foreman, armed with his new weapon (accurate time study), to drive the workmen, against their wishes, and without much increase in pay, to work much harder, instead of gradually teaching and leading them toward new methods, and convincing them through object-lessons that task management means for them somewhat harder work, but also far greater prosperity. The result of all this disregard of fundamental principles was a series of strikes, followed by the down-fall of the men who attempted to make the change, and by a return to conditions throughout the establishment far worse than those which existed before the effort was made.

In this connection, however, it is proper to again state that during the thirty years that we have been engaged in introducing scientific management there has not been a single strike from those who were
working in accordance with its principles, even during the critical period when the change was being made from the old to the new. If proper methods are used by men who have had experience in this work, there is absolutely no danger from strikes or other troubles.


16. Role of Top Management in Implementing Scientific Management

Directors of the Company Have to Understand the Fundamental Principles of Scientific Management


The writer would again insist that in no case should the managers of an establishment, the work of which is elaborate, undertake to change from the old to the new type unless the directors of the company fully understand and believe in the fundamental principles of scientific management and unless they appreciate all that is involved in making this change, particularly the time required, and unless they want scientific management greatly.

Distribution of Productivity Gain between Shareholders, Employees and Consumers



At the first glance we see only two parties to the transaction, the workmen and their employers. We overlook the third great party, the whole people,--the consumers, who buy the product of the first two and who ultimately pay both the wages of the workmen and the profits of the employers.

The rights of the people are therefore greater than those of either employer or employee. And this third great party should be given its proper share of any gain. In fact, a glance at industrial history shows that in the end the whole people receive the greater part of the benefit coming from industrial improvements. In the past hundred years, for example, the greatest factor tending toward increasing the output, and thereby the prosperity of the civilized world, has been the introduction of machinery to replace hand labor. And without doubt the greatest gain through this change has come to the whole people--the consumer.

Through short periods, especially in the case of patented apparatus, the dividends of those who have introduced new machinery have been greatly increased, and in many cases, though unfortunately not universally, the employees have obtained materially higher wages, shorter hours, and better working conditions. But in the end the major part of the gain has gone to the whole people.

And this result will follow the introduction of scientific management just as surely as it has the introduction of machinery.

The writer is one of those who believes that more and more will the third party (the whole people), as it becomes acquainted with the true facts, insist that justice shall be done to all three parties. It will demand the largest efficiency from both employers and employees. It will no longer tolerate the type of employer who has his eye on dividends alone, who refuses to do his full share of the work and who merely cracks his whip over the heads of his workmen and attempts to drive them into harder work for low pay. No more will it tolerate tyranny on the part of labor which demands one increase after another in pay and shorter hours while at the same time it becomes less instead of more efficient.

And the means which the writer firmly believes will be adopted to bring about, first, efficiency both in employer and employs and then an equitable division of the profits of their joint efforts will be scientific management, which has for its sole aim the attainment of justice for all three parties through impartial scientific investigation of all the elements of the problem. 



17. Scientific Management Summarized


Last and Concluding Part of Scientific Management by F.W. Taylor



It is no single element, but rather this whole combination, that constitutes scientific management, which may be summarized as:

  Science, not rule of thumb.
  Harmony, not discord.
  Cooperation, not individualism.
  Maximum output, in place of restricted output.
  The development of each man to his greatest efficiency and prosperity.



The examples given above of the increase in output realized under the new management fairly represent the gain which is possible. They do not represent extraordinary or exceptional cases, and have been selected from among thousands of similar illustrations which might have been given.

Let us now examine the good which would follow the general adoption of these principles.

The larger profit would come to the whole world in general.

The greatest material gain which those of the present generation have over past generations has come from the fact that the average man in this generation, with a given expenditure of effort, is producing two times, three times, even four times as much of those things that are of use to man as it was possible for the average man in the past to produce. This increase in the productivity of human effort is, of course, due to many causes, besides the increase in the personal dexterity of the man. It is due to the discovery of steam and electricity, to the introduction of machinery, to inventions, great and small, and to the progress in science and education. But from whatever cause this increase in productivity has come, it is to the greater productivity of each individual that the whole country owes its greater prosperity.

The general adoption of scientific management would readily in the future double the productivity of the average man engaged in industrial work. Think of what this means to the whole country. Think of the increase, both in the necessities and luxuries of life, which becomes available for the whole country, of the possibility of shortening the hours of labor when this is desirable, and of the increased opportunities for education, culture, and recreation which this implies. But while the whole world would profit by this increase in production, the manufacturer and the workman will be far more interested in the especial local gain that comes to them and to the people immediately around them. 

The low cost of production which accompanies a doubling of the output will enable the companies who adopt this management, particularly those who adopt it first, to compete far better than they were able to before, and this will so enlarge their markets that their men will have almost constant work even in dull times, and that they will earn larger profits at all times.

This means increase in prosperity and diminution in poverty, not only for their men but for the whole community immediately around them.

As one of the elements incident to this great gain in output, each workman has been systematically trained to his highest state of efficiency, and has been taught to do a higher class of work than he was able to do under the old types of management.

Is not the realization of results such as these of far more importance than the solution of most of the problems which are now agitating both the English and American peoples? And is it not the duty of those who are acquainted with these facts, to exert themselves to make the whole community realize this importance?
