Principles of Motion Economy for Process Human Effort Industrial Engineering - Gilbreth  - R.M. Barnes

Principles of Motion Economy



Principles of Motion Economy are to be used in motion design, motion analysis, motion study of human operators. Motion design is a technique of Human Effort Industrial Engineering, a core focus area of Industrial Engineering. They can also be used in robot motion design.

Functions and Focus Areas of Industrial Engineering

______________________________________________________________

Principles of motion economy emerged out of the productivity science of human effort and motions pioneered in detail by Frank Gilbreth along with F.W. Taylor.

Use of the Human Body



1. The two hands should begin as well as complete their motions at the same time.


2. The two hands should not be idle at the same time except during rest periods.


3. Motions of the arms should be made in opposite and symmetrical directions and should be made simultaneously.


4. Hand and body motions should be confined to the lowest classification with which it is possible to perform the work satisfactorily.



5. Momentum should be employed to assist the worker wherever possible, and it should be reduced to a minimum if it must be overcome by muscular effort.



6. Smooth continuous motion of the hands are preferable to straight line motions involving sudden and sharp changes in direction.



7. Ballistic movements are faster, easier and more accurate than restricted (fixation) or controlled movements.



8. Work should be arranged to permit an easy and natural rhythm wherever possible.

See Work Station Design - Introduction

9. Eye fixations should be as few and as close together as possible.





Arrangement of the workplace




10. There should be a definite and fixed place for all tools and materials. (5S)

Principles of Motion Economy - Details

Use of the Human Body

1. The two hands should begin as well as complete their motions at the same time.

2. The two hands should not be idle at the same time except during rest periods.

3. Motions of the arms should be made in opposite and symmetrical directions and should be made simultaneously.

Barnes has written that the three principles can be examined or discussed simultaneously. He gave the example of bolt and washer assembly. In the old method bolt is picked up by the left hand and then a lock washer is picked up by the right hand placed on the bolt. Next, the right hand picks up a steel washer and placed on the bolt. Then a rubber washer is picked up the right hand and placed on the bolt. The completed assembly is disposed of in a container placed at the left side of the operator. As we can see two hands are moving simultaneously. One is holding the bolt and the other hand is doing picking and assembling work. In the revised method, a fixture is made that holds two bolts and has recess. The operator has 7 bins before him. He first pickups a rubber washer from bins numbered one on left and right. Actually the bottom of the bins slope toward the work area at a 30 degree angle so that materials are fed onto the work area by gravity. The operator slides the washers into the recesses of the fixture. Then steel washers are slided. The the lock washer is slided into position. Two bolts are picked and dropped into the fixture. Then both bolts are removed and disposed of in bins placed on the right side as well as left side. In the return motion they pick the new rubber washers.
You can visualize how all three principles are applied in the new design.

See video clip easier way produced by General Motors in 1946 illustrating these principles.

4. Hand and body motions should be confined to the lowest classification with which it is possible to perform the work satisfactorily.

Classification of Hand-motions
1. Finger motions
2. Wrist motions
3. Forearm motions
4. Upper arm motions
5. Shoulder motions (This class of motions results in disturbance of the posture)

Barnes highlighted that in one investigation it was found that finger motions were more fatiguing, less accurate, and slower than motions of the forearm. The evidence points out that th forearm is the most desirable member to use for light work, and that in highly repetitive work,motions about the wrist and elbow are superior to those of the fingers or shoulders.

Bending has physiological cost. A study made by Barnes et al. on picking bricks from a platform 5 inches above the floor and another platform 37 inches above the floor to place them on a bench 33 inches high showed that both energy expenditure and heart beat were high when picking up bricks from 5 inch high platform. These sort of experiments are to be conducted by industrial engineers in their motion studies to improve the comfort and health of operators.

5. Momentum should be employed to assist the worker wherever possible, and it should be reduced to a minimum if it must be overcome by muscular effort.

In certain tasks, it is possible to employ momentum of the hand, the tool or the part being moved to do useful work.  Where a forcible stroke is involved, the motions have to be arranged such that the stroke is delivered with the greatest momentum. In the tasks where the momentum must be overcome by the worker's muscles, momentum must be reduced to a minimum by decreasing the weight of the tools and parts because it causes fatigue.

Barnes quoted Gilbreth's motion study. In laying a brick wall, if the bricks are conveyed from the stock platform to the wall with no stops, the momentum can be made to do valuable work by assisting to shove the joints full of mortar. If instead of being utilized, the momentum must be overcome by the muscles of the bricklayer, fatigue will result. The idea case is to move the brick in a straight path and make the contact with the wall to overcome the momentum.

Barnes quoted another example of candy dipping. He pointed out that  the piece tobe dipped was submerged under the surface of the melted sugar by the right hand at the end of a long return stroke of the hand and the momentum developed in the movement of the hand was employed in doing useful work instead of being dissipated by the muscles of the dipper's arm.

6. Smooth continuous curved motions of the hands are preferable to straight-line motions involving sudden and sharp changes in direction.

Barnes has given the examples of paper holding and dipping of candy to illustrate this point.

7. Ballistic movements are faster, easier, and more accurate than restricted or fixation or controlled movements.

Voluntary movements of the members of the human body may be divided into two general classes or groups: fixation movements and ballistic movements.

In the fixation or controlled movements, opposing groups of muscles are contracted, one group against the other. .

The ballistic movement is a fast, easy motion caused by a single contraction of a positive muscle group with no antagonistic muscle group contracting to oppose it.

The ballistic movement is initiated by an impulse given through the contraction of a muscle, once underway the muscles are relaxed and the course of the movement can not be changed.

The skilled carpenter swinging a hammer in driving a nail illustrates a ballistic movement.

It is not difficult to develop the free, loose, easy movements of the wrist and forearm.



8. Work should be arranged to permit an easy and natural rhythm wherever possible.

Rhythm can refer to the regular repetition of a certain cycle of motions by an individual. Rhythm which is a proper sequence of motions, assists in making the operation practically an automatic performance - there is no mental effort on the part of the operator.

9. Eye fixations should be as few and as close together as possible.

The work place should be so laid out that the eye fixations are as few and as close together as possible. In one example given in Barnes, the author comments that, had the containers been placed directly in front of the operator, the head movements would have been eliminated entirely and he eye movements would have been greatly reduced.

In another example, Barnes highlights that with practice eye fixations come down and the time required also comes down accordingly. This example is related to the punch-press operation wherein, a part has to be placed in the die using a tweezer. Initially, three eye fixations are used. One for placing the parts in the die, one for taking the part from the left hand with the tweezer and one for taking the part in left hand from the plate having the parts. After 10,000  cycles, only 44 per cent of the time. eye fixation is used pick up the part from the plate having the parts. 56 per cent of the time, the part is being picked up by the left hand without an eye fixation.  The average time for the operation has come down to 0.0258 minutes from 0.0584 minutes. One of the reasons was the decrease in number of eye fixations.

Principles Related to the Work Place


10. There should be a definite and fixed places for all tools and materials.

Definite and fixed places for materials and tools aid the operators in habit formation. This helps in the development of automaticity. It is advantage when operators can perform the operations with the least conscious mental direction. When materials and tools are at fixed places, the hand automatically finds them without support of eyes and the eyes may be kept fixed on the point where the tools and materials are used.

5S - In Japanese companies this principle was implemented with special focus under the name "5S"

11. Tools, materials, and controls should be located close to the point of use.

For an operators , sitting or standing, the comfortable working place is bounded by lines which are arcs of circles.

The maximum working area for each hand is determined by an arc drawn with a sweep of the hand across the table, with the arm pivoted at the shoulder. In the overlapping area work involving both hands can be done comfortably.

Each hand has its normal working area in the vertical plane as well.

Those tools and parts that must be handled several times during an operation should be located closer to the fixture or working position than tools or parts that are handled but once. For example  if an operation consists of assembling a number of screws into a metal switch plate, the containers for the screws should be placed closer to the fixture than container for the plates as only one plate is to be transported and several screws have to be transported in a cycle.

It is also important to emphasize that parts must be arranged in such a way as to permit the shortest eye movements, the fewest eye fixations, and the best sequence of motions, and to aid the operator in rapidly developing automatic and rhythmic movements.

Interesting example: A radio assembly consists of 260 separate parts/subassemblies. Moving the parts closer by 6 inches saved 34,000 hours per year. which means saving of 17 mandays.

Corollary: The machines, process apparatus, and equipment should be arranged so as to require the least movement on the part of the operator.

When worker operates several machines and when they are located in line along an aise, considerable walking between machines is required. A better arrangement is to have those machines located close together in a group so that the operator can load and unload each of the machines with little or no travel.

See Work Station Design - Introduction

12. Gravity feed bins and containers should be used to deliver material close to the point of use.

Bins with sloping bottoms provide the parts at the bottom tray of the bin and operator need not dip into the bin to pick up the part. To provide many different parts, nested bins one above the other are used.

Bins and hopper for process shops - http://www.processsolutions.net/bins.html

13. Drop deliveries should be used wherever possible.

Arrangements are to be done to release the finished units from the position is was completed and deliver them to their destination by gravity.

There is significant amount of time involved in manually disposing the finished items. A study of disposing gauging small pins was conducted in this context. The study involved disposing of the pins into a tote box kept as 3 inches behind a fixture, 10 inches behind a fixture and 20 inches behind a fixture.

The time was least when the pins were tossed into the bin 3 inches near the fixture. The therbligs involved were transport loaded and release load. Eighteen percent more time was used when the bin was at 10 inches and 34 per cent more time was spent when the bin was kept at 20 inches distance.


14. Materials and tools should be located to permit the best sequence of motions.

The material required at the beginning of a task cycle should be place next to the point of release of the finished piece in the preceding task cycle.


In the example of assembly of the bolt and washers (points 1,2 and 3) the rubber washers were in bins located nearest to the chute into which assemblies were disposed in the last motion of the previous cycle.

The time for a motion changes based on the preceding or succeeding motion. For example, the time for the motion transport empty is likely to be longer when it is followed by the motion select than when it is followed a well defined motion such as a grasp of a pre-positioned part.

When the motion transport loaded is followed by a position motion, it is slowed by the mental preparation for the position.

15. Provisions should be made for adequate conditions for seeing. Good illumination is the first requirement for satisfactory visual perception.

Adequate illumination means:
(1) light of sufficient intensity for the particular task,
(2) light of the proper color and without glare, and
(3) light coming from the right direction.

The visibility of an object is determined by the following variables.

# Brightness of the object
# Its contrast with its background
# The size of the object
# The time available for seeing
# The distance of the object from the eye and
# Other factors such as distractions, fatigue, reaction time, and  glare.

All of these factors must be above a limiting value and then a deficiency in one may be compensated by an augmentation of one or more of the others.

 16. The height of the work place and the chair should preferably arranged so that alternate sitting and standing at work are easily possible.

17. A chair of the type and height to permit good posture should be provided for every worker.
Design of tools and equipment


Principles of Motion Economy As Related to the Design of Tools and Equipment



18. The hands should be relieved of all work that can be done more advantageously by a jig, a fixture, or a foot-operated device.


Barnes has written that foot operated equipment is not utilized adequately in methods and tool design (p.223). He also mentions that one company saved 50 percent time on the operation of soldering a wire to the end of flat metal electric static shield by the use of a foot-operated soldering iron. The brief description of foot operated soldering iron was given in the book by Barnes. 


Procter and Gamble designed and built foot control units which rotate the pipe or tube when welder is cutting and welding pipes.


It is also possible to use two foot pedals to actuate different parts of a jig, fixture, or machine by the operator. This arrangement will be similar to the automobile where there are pedals for accelerator, brake and clutch.

19. Two or more tools should be combined wherever possible.



Develop and use two ended tools. It is usually quicker to turn a small two-ended tool end-for-end that it is to lay one tool down and pick up another.  Tack hammer and tack puller, two-ended wrench, and pencil  and erasure are good examples. The designer of telephone handset used this idea only when in one unit he arranged both the transmitter and receiver.


At a mid-western electric company two combination tools were developed. One the screw driver and tweezers. The other is a wrench and screw driver.

The multiple-spindle air-operator nut runner for automobile wheels is another good example of combination tool.

20. Tools and materials should be pre-positioned whenever possible.


Pre-positioning refers to placing an object in a predetermined place in such a way that when next needed it may be grasped in the position in which it will be used.


Tools are kept in specified holders in the form of socket, compartment, bracket or hanger all the time when there are not in use. They are returned or kept in the same position by the operator after they are used. The design of the holder is to be such that the tool is quickly released into its place. Also, it should facilitate quick grasping for use.

It is important to state again that, the holder of the tool should be designed in such a way that, the tool can  be grasped in the same manner in which will be held while being used.

See Work Station Design - Introduction

21. Where each finger performs some specific movement, such as in typewriting, the load should be distributed in accordance with the inherent capacities of the fingers.


22. Levers, hand wheels and other controls should be located in such positions that the operator can manipulate them with the least change in body position and with the greatest speed and ease.

Unless a machine is fully automatic, the amount of work that it will produce depends to some extent upon the performance of the operator. The time taken by the operator to handle levers, hand wheels and other controls has an impact on production quantity.  

The operator should not be required to leave his normal working position to operate his machine. The controls of machines should be placed in such a way that he need not bend over or twist his body in an uncomfortable manner when manipulating  them.

Exhaustive studies were done to indicate good location for levers and hand wheels.



Example: Barnes have given the example of Jones and Lamson CNC Lathe. It was provided with a small control center, located at the front of the machine with an alpha numeric keyboard for instant on-line commands and editing, plus a CRT display. The operator has a greater access to all working areas.

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

Motion study is an important method of industrial engineering. It is a task within process improvement that has primarily improvement of machine effort and human effort. Motion study is method of human effort or work improvement. Two handed process or work chart is an important chart that facilitates motion study.


MOTION STUDY AND TIME STUDY INSTRUMENTS OF PRECISION 

(Presented by Gilbreth at the International Engineering Congress. ) 


The greatest waste in the world comes from needless, ill-directed, and ineffective motions. These motions are unnecessary and preventable. Now the methods and devices of waste elimination are known and are being constantly used. But the knowledge of how to make these great world-wide economies is being disseminated at an astonishingly slow pace. This paper is for the purpose of disseminating such knowledge, particularly as to the devices that are used for making the measurements  (*remember: industrial engineering measurements) that enable us to eliminate waste. 

In the science of management, as in all other sciences, progress that is to be definite and lasting depends upon the accuracy of the measurements that are made. There are three elements to every measurement : 

1. The unit measured. 

2. The method of measurement. 

3. The device by which the measurement is made. 

It is here our aim to show the development of the devices of measurement, that is, of instruments of precision that apply to one branch of the new type of management, namely, to motion study and its related time study. 

The fundamental idea of the new type of management that has been variously called "Scientific Management," or "Measured Functional Management," is that it is based upon the results of accurate measurement. This fundamental idea has been derived as follows : Each operation to be studied is analysed into the most elementary units possible. These units are accurately measured, and, as the results of the measurement, the efficient units only are combined into a new method of performing the work that is worthy to become a standard. 

(Dr. Taylor, the great pioneer in time study, and his co-worker, Mr. S. E. Thompson, have clearly defined their conception of time study as "the process of analysing an operation into its elementary operations, and observing the time required to perform them." Time study has to do, then, fundamentally, with the measurement of units of time. Additional comments by me: The purpose of time study is to understand the drivers of time and to reduce the time and then validate it with another time study. So time study before improvement and time study after improvement.)

Now motion study has to do with the selection, invention, and substitution of the motions and their variables that are to be measured. Both accurate time study and motion study require instruments of precision that will record mechanically, with the least possible interference from the human element, in permanent form, exactly what motions and results occur. For permanent use the records must be so definite, distinct, and simple that they may be easily and immediately used, and lose none of their value or helpfulness when old, forgotten, or not personally experienced by their user. 

It was not, however, until Dr. Taylor suggested timing the work periods separately from the rest periods that the managers tried to find accurate time-measuring devices. 

It is not always recognised that some preliminary motion study and time study can be done without the aid of any accurate devices. It is even less often recognised that such work, when most successful, is usually done by one thoroughly conversant with, and skilled in, the use of the most accurate devices. In other words, it is usually advisable in studying an operation to make all possible improvements in the motions used and to comply broadly with the laws of motion study before recording the operation, except for the preliminary record that serves to show the state of the art from which the investigation started. However, in order to make a great and lasting success of this work, one must have studied motions and measured them until his eye can follow paths of motions and judge lengths of motions, and his timing sense, aided by silent rhythmic counting, can estimate times of motion with surprising accuracy. Sight, hearing, touch, and kinesthetic sensations must all be keenly developed. With this training and equipment, a motion- and time-study expert can obtain preliminary results without devices, that, to the untrained or the uninformed, seem little short of astounding. When the operation has received its preliminary revision and is ready for the accurate measurements that lead to actual standardisation and the teaching that follows, devices of precise measurement become imperative for methods of least waste that will stand the test of time. Early workers in time study made use of such well-known devices as the clock, the watch, the stop-watch, and various types of stop-watches attached to a specially constructed board or imitation book. Through the use of these it became possible to record short intervals of time, subject, of course, always to the personal error. The objection to the use of these methods and devices is their variation from accuracy, due to the human element. This is especially true of the use of the stop-watch, where the reaction time of the observer is an element constantly affecting the accuracy of the records. But the greatest loss and defect of personally observed and recorded times is that they do not show the attending conditions of the varying surroundings, equipment and tools that cause the differences in the time records, and give no clue to causes of shortest or quickest times. 

Being unable to find any devices anywhere such as the work of our motion study required, the problem that presented itself, then, to us who needed and desired instruments of precision, applicable to our motion study and to our time study, was to invent, design and construct devices that would overcome lacks in the early and existing methods. It was necessary to dispense with the human element and its attending errors and limitations. We needed devices to record the direction as well as the path or orbits of motions, and to reduce the cost of obtaining all time study and motion study data. These were needed not only from the scientific standpoint, but also from the standpoint of obtaining full co-operation of the mechanics and other workers. 

Through our earliest work in making progress records we recognised the necessity of recording time and conditions accurately and simultaneously, the records being made by dated photographs. This method was particularly applicable in construction work,  where progress pictures taken at frequent intervals present accurate records of the surroundings, equipment and tools that affect records of output of various stages of development. 

In making more intensive studies of certain trades, such as shovelling, concrete work, and bricklaying, we found it advantageous to photograph the various positions in which the hands, arms, feet, and other parts of the body involved in the operations were placed, and to record the time taken in moving from one position to another by one method, as related to the time taken in moving from the same first to the same second position by another method.  Our intensive study of bricklaying, which grew out of an appreciation of the unique history, present practice and doubtful future of this trade, led us to a more intensive study of the problems of motion and time study in general.  Bricklaying will always be the most interesting of all examples to  us, for one reason, among others, that it was the first trade to use the principle of duplicate, interchangeable parts system of construction; had had six thousand known years of practice in all countries; and was, therefore, a comparatively finished art, but not a science, when we undertook to change it by means of motion study. 

Fortunately, we are now able to use the motion picture camera with our speed clock, and other accessories, as a device for recording elements of motion and their corresponding times, simultaneously. Our latest microchronometer records intervals of time down to any degree of accuracy required. We have made, and used, in our work of motion study investigations of hospital practice and surgery, one that records times to the millionth of an hour. This is designed for extremely accurate work, but can be adjusted to intervals of any length desired, as proves most economical or desirable for the type of work to be investigated. 

Having completed our microchronometer, we proceeded as follows: The microchronometer was placed in the photographic field near the operator and his working equipment, and against a cross-sectioned background or in a cross-sectioned field, and at a cross-sectioned work bench or table. The operator then performed the operation according to the prescribed method, while the motion-picture camera recorded the various stages of the operation and the position of the hand on the microchronometer simultaneously. Thus, on the motion picture film we obtain intermittent records of the paths, the lengths, The directions, and the speeds of the motions, or the times accompanying the motions, these records all being simultaneous; and the details of the conditions of the surroundings that are visible to the eye are recorded without the failings of memory. This was a distinct step in advance, but we realised that there was a lack in the records. It was difficult, even for one especially trained and experienced to visualise the exact path of a motion, and it was not possible to measure the length with precision from the observations of the motion picture film alone, as there is no summary or recapitulation of all the motions of a cycle or operation in any one picture. To overcome this lack we invented the cyclegraph method of recording motions. This consists of attaching a small electric light to the hand or other moving part of the person or machine under observation. The motion is recorded on an ordinary photographic film or plate. Upon observing our very first cyclegraph records, we found that we had attained our desire, and that the accurate path taken by the motion stood before us in two dimensions. By taking the photographic record stereoscopically, we were able to see this path in three dimensions, and to obtain what we have called the stereocyclegraph. This showed us the path of the motion in all three dimensions ; that is, length, breadth, and depth. It did not, however, contain the time element. This time element is of great importance not only for comparative or " relative " time, but also for exact times. This time element is obtained by putting an interrupter in the light circuit, that causes the light to flash at an even rate at a known number of times per second. This gives a line of time spots in the picture instead of a continuous cyclegraph light line. Counting the light spots tells the time consumed. 

The next step was to show the direction of the motions. To do this it was necessary to find the right combination of volts and amperes for the light circuit and the thickness of filament for the lamp, to cause quick lighting and slow extinguishing of the lamp. This right combination makes the light spots pointed on their latest, or forward, ends. .The points, thus, like the usual symbol of arrow heads, show the direction. The result was, then, of course, finally, stereochronocyclegraphs showing direction. These act not only as accurate records of the motions and times, but also serve as admirable teaching devices. 

Wire models of cyclegraphs and chronocyclegraphs of the paths and the times of motions are now constructed that have a practical educational value besides their importance as scientific records. These models are particularly useful as a step in teaching visualisation of paths by photographs alone, later. 

Our latest apparatus in the field of recording devices apparently fulfils all present requirements of the time- and motion-study experts and their assistants and the teachers who are now devoting their lives to the transference of skill and experience from those who have it to those who have not. 

We have also devised and used many special kinds of apparatus ; for example, devices for recording absolute continuity of motion paths and times, doing away with the slight gaps in the record that occur between one picture and the next on the cinematograph film, due to the interval of time when the film is moving, to get in place for the next exposure. To overcome this objection we have a double cinematograph) that ! one part may record while the other moves from one exposure to the next. In this way we get a continuous record of the operation. There have been occasional objections to all methods of making time and motion studies that involve the presence of an observer. Some of these have come from those working on what they consider their own secret processes, who object to having any observer record what they are doing, believing that the time study man is obtaining knowledge of their skill and giving them no information in return. Others have come from those who have seen or heard " secret time study " and " watch- book time study," and who regard all observers as spies because of general lack of understanding ! and co-operation; and there are some instances where they are right. For such cases we have designed an automicromotion study, which consists of an instantaneous modification of the standard micromotion apparatus, and also the autostereochronocyclegraph apparatus. This enables the operator to take accurate time study of himself. He can start the apparatus going and stop it from where he works, with one motion of his finger or foot. This invention supplies every possible requirement and feature for time and motion study processes, except the help and advice of a properly qualified observer, or the annoyance of having one not fitted by training, experience, or natural qualities to co-operate. 

There is not space in this paper for a discussion of the educational features of observations made with these devices, or of their influence upon the new and much needed science of fatigue study, or of their general psychological significance. 1 It is only necessary to emphasise their adaptability, flexibility, and relation to economy. We have here a complete set of inexpensive, light, durable apparatus, adaptable to any type of work and to any type of observer or self -observation. 

It consists of systematically assembled units that may be so combined as to meet any possible working condition. Through a specially devised method of using the same motion picture film over and over again, up to sixteen times, and through a careful study of electrical equipment and of various types of time spot interrupters, we have been enabled to cut down the cost of making time and motion study, until now the most accurate type of studies, involving no human equation in the record, can be made at less cost than the far less accurate stop-watch study. This time study and motion study data can be used when it is " cold." No specially gifted observer, combined with the most willing and efficient recorder, can compete with it for observing and recording facts. 

It does not depend upon a human memory to "give up" its facts. It is usable at any time and forever, after it is once taken. Naturally, the requirements for refinement and the special set-ups to be used in any case must be determined after some study of the case in hand. 

There are now available, therefore, instruments of precision fitted to make measurements as fine as the most exact science demands, economical enough to make both immediate and ultimate savings, and that meet the demands of the most exacting industrial progressive. When the time and motion study is taken with such instruments of precision, there are still other by-products that are of more value than the entire cost of the time and motion studies.

Very interesting to read. I think you need design thinking to create a product or service for users. But if the user complains about the product's performance, how do you debug? System's thinking is needed. You do not take something as a cause and modify. You try to understand the root cause or systemic cause and modify it to really improve the system before presenting the modified solution to the customer. So as you said, design thinking is understanding customer point of view, systems thinking is understanding the intricacies in your product. Thank you for the detailed article.

Regarding technology side of operational excellence, which is important aspect of industrial engineering, we have to say, involve people in technology decisions. Get the concurrence of existing people in the organization for technology decisions.

I tried to discuss the issue with Joseph Paris through comments some time back. He was not willing to discuss any other view except that of saying people are first.

Operational Excellence is  a system.0f 5 Pillars.

Here’s how the SQDCP five pillars can change your operations:

1️⃣ 𝗦𝗮𝗳𝗲𝘁𝘆:
- Unsafe conditions derail productivity and add costs.
- Focus on building a safe workspace, and watch efficiency rise.

2️⃣ 𝗤𝘂𝗮𝗹𝗶𝘁𝘆:
- Quality doesn’t cost; poor quality does.
- Set high standards and fix issues at the source.

3️⃣ 𝗗𝗲𝗹𝗶𝘃𝗲𝗿𝘆:
- Late delivery kills trust.
- Meet deadlines consistently to build client confidence.

4️⃣ 𝗖𝗼𝘀𝘁:
- Cost control isn’t about cutting, it's about using resources wisely. (Productivity of Resources - Industrial Engineering)
- Streamline processes to reduce waste, not quality.

5️⃣ 𝗣𝗲𝗼𝗽𝗹𝗲:
- People drive change; machines don’t.
- Train, motivate, and listen to your team. They’re the backbone of excellence.

Comment by Jim Beckham
Retired Director, Total Quality Management at JTEKT Corporation


I find the comments on priority an interesting discussion point. Let me contribute from someone who worked 14 years at one of the Toyota group of companies. We only used the first four, in priority sequence, SQDC. But it’s important to understand which stakeholder is impacted by each:
Safety- Employee stakeholder;
Quality - Customer stakeholder;
Delivery - Customer stakeholder; and
Cost - Shareholder stakeholder.

When management, an improvement team or a QC Circle follows the 8-Step Problem Solving method to make an improvement to one of these four areas, the solution for the improvement can not adversely impact the areas above. For example it a team was trying to improve productivity (Cost) and the improvement would make it more dangerous for the workers, or create a quality defect, or impact delivery, then the team would have to find another solution.


Additional Comment by Jim Beckham, Retired Director, Total Quality Management at JTEKT Corporation


Just to be clear, an improvement could be made that adversely impacts an area below and that would ok. For example, when fixing a Quality problem the solution can’t adversely impact Safety (which is above), but it could adversely impact Cost or Delivery (which are below). This is ok. It then gives the improvement team motivation to then solve the secondary Cost or Delivery problem. A little pain is always a good motivator for teams to take ownership and to improve.
