Management and Industrial Engineering

Industrial Engineering (IE) is a service to management and MBA curriculums must include IE as a subject to appreciate its role in proper management of the organizations.

Management Definition

Management of an organization is the process of establishing objectives and goals of the organization periodically, designing the work system and the organization structure, and maintaining an environment in which individuals, working together in groups, accomplish their aims and objectives and goals of the organization effectively and efficiently (Narayana Rao).

The above definition was developed by me by modifying the definition given by Koontz and O'Donnell.

The definition implies the following.

(i) Management is a process.
(ii) Management applies to every kind of organization, government, profit making, or nonprofit making.
(iii) It applies to managers at all levels in the organization.
(iv) Management is concerned with effectiveness and efficiency.

Effectiveness and efficiency when combined are explained as productivity by Koontz and O'Donnell.
Weihrich and Koontz defined Management and explained it as follows in the tenth edition of their book Management: A Global Perspective (p.4).
"Management is the process of designing and maintaining an environment in which individuals, working together in groups, efficiently and accomplish selected aims." This definition needs to be expanded:
1. As managers, people carry out the managerial functions of planning, organizing, staffing, leading, and controlling.
2. Management applies to any kind of organization.
3. It applies to managers at all organizational levels.
4. The aim of all managers is the same: to create a surplus.
5. Managing is concerned with productivity; this implies effectiveness and efficiency.

Industrial engineering is a discipline that evolved out of the involvement of engineers in managing engineering departments of enterprises. Frederick Taylor and Frank Gilbreth are pioneers of this branch - which is a hybrid  of engineering and management and  is a service to management.

Narayana Rao defined industrial engineering as: "Industrial Engineering is Human Effort Engineering and System Efficiency Engineering. It is an engineering discipline that deals with the design of human effort and system efficiency in all occupations: agricultural, manufacturing and service. The objectives of Industrial Engineering are optimization of productivity of work-systems and occupational comfort, health, safety and income of persons involved." (  Industrial Engineering )

The statement "Industrial Engineering is Human Effort Engineering and System Efficiency Engineering" appeared in the Industrial Engineer (March 2010 issue), magazine of Institute of Industrial Engineers (IIE), which is the global association of Productivity and Efficiency professionals.

When both the definitions are examined together, one can easily conclude that industrial engineering is a service to management focusing on the efficiency aspect, which is a function of the management. Managers whenever they require a specialist looking after efficiency, in the division of labor based work organization, employ the services of industrial engineers.

Industrial engineering techniques and tools build efficiency into systems. Production management texts do cover some of the techniques of industrial engineering. Design professionals get some inputs in value engineering. A better system would be to introduce a course on industrial engineering in business curriculums so that business school graduates understand the profession and discipline of industrial engineering appropriately and make use of the services of IE departments in various functions of management.

Job Evaluation - Purpose - Consultants

Job evaluation is an instrument available to ensure integration of internal fairness and external competitiveness. A well-designed, carefully implemented job evaluation system is not only a basic tool for driving changes in your company’s reward structures and achieving equal pay for work of equal value, it also defines the value of a job within your company.

PricewaterhouseCoopers (PwC)

PricewaterhouseCoopers (PwC) can help you in the process

PricewaterhouseCoopers (PwC)  can help you develop and implement all, or part, of a job-evaluation system designed to meet the specific needs of your company.
They claim:
Our experienced professionals know how to listen, and they know what questions to ask so that they get the right answers. We can then help you to create the processes and the tools you will need, and, if needed, train your staff in their use. Or, if you would prefer, we can undertake the entire process for you: writing job descriptions, designing or selecting a job-evaluation method, and implementing the chosen method—either PricewaterhouseCoopers’ own IFA or STRATA method, or a 100% customised system, or a system based on a combination of existing methods (already gathered in a database or customised methods). We can also negotiate with the unions in your company; create an effective communications plan, and hold information sessions for your employees; deploy new job classifications, benchmark your salary structure, and implement and maintain the complete procedure, from beginning to end. At PwC our aim is to make your job as easy and effective as possible.

PWC says you consider them when:
• You need a refined evaluation system that includes people's competences.
• You need a evaluation process that can be easily be monitored and adjusted quickly when needed.
• Your company is complex enough to require a number of job evaluation systems that target different groups and objectives.
• You want to develop a job classification procedure that is not a self-contained process but is wholly integrated into the HR value chain—recruitment, salary management, performance management, development and career management).
• You need a new evaluation system that allows you to manage people development and ensure that appropriate skills are developed.

Hay Group

Hay group provides assistance in job evaluation. It claims:
A consistent, objective framework

Thousands of organizations – including more than half of the world’s largest companies – rely on Hay Group’s job evaluation methodologies to help them bring together the right people, jobs and structures to execute their strategies.
The main Hay Group methodology, the Hay Guide Chart®-Profile Method of Job Evaluation provides you with a consistent and objective framework to:
  • analyze your organizational structure and identify ways to make it more effective
  • evaluate people and jobs to match the right individuals to the right roles
  • define career progressions both from individual roles and across related job groups and
  • develop targeted pay and reward programs, using Hay Group’s global compensation database.

All of this ultimately leads to an increased ability to manage your human resources more effectively.
Evolving evaluation

Crucially, this isn’t a one-off approach: the Hay Group job evaluation method is designed to evolve with your business. As a result, several Hay Group clients have used the method successfully to help with job design, talent development and performance management for over 25 years.

Perfection is achieved, not when there is nothing left to add, but when there is nothing left to remove. - Saint-Exupery

Unable to eliminate bottlenecks in production
EOQ - Economic Lot Size - calculation of best use of line, production must be high enough to meet demand for different models

different model = different parts, different dies, different procedures, different tools

high downtime for line changeover = high economic lot size
high economic lot size = high stock  of parts inventory
high stock of inventory = investment of $$$, land costs in Japan are expensive, high cost for big warranty
lesser diversity of models

First - rework factory and models to make use of standard parts, tools, and processes.

Next goal is SMED
biggest component of changeover is die exchange
examine process -
die weighs many tons
use crane to remove old and install new
requires minute measurement to put into place
done by hand and by eye
tested by making test stampings, wasting time and resources
process took 12 hours to 3 days

invest in precision measurement devices
record necessary measurements for each die
install according to measurements rather than by hand and eye - changeover to 90 minutes

FRS - fixed repeating schedule
die changes in standard sequence
scheduling tool changeovers as the new product moved through factory
scheduling use of cranes

SMED achieved
Single Minute Exchange of Die
<10 minutes to change die.
EOQ = 1 vehicle.
Just in time manufacturing

intangible benefits
stockless production
reduction of process footprint = free floor space
productivity increased

Human Effort Engineering

Human Effort Engineering - The Concept and Techniques

Human effort engineering is a term used in describing and defining industrial engineering by Narayana Rao.

Industrial Engineering can be described adequately by three components.

1. Human Effort Engineering

2. Systems Efficiency Engineering

3. Systems Design, Installation and Improvement Management



Human effort engineering is a term used in describing and defining industrial engineering by Narayana Rao.
The definition of industrial engineering given by Narayana Rao is:
“Industrial Engineering is Human Effort Engineering. It is an engineering discipline that deals with the design of human effort in all occupations: agricultural, manufacturing and service. The objectives of Industrial Engineering are optimization of productivity of work-systems and occupational comfort, health, safety and income of persons involved.” According to this definition the two focus areas of industrial engineering are human effort engineering and systems efficiency/productivity engineering.

Narayana Rao, K.V.S.S., “Definition of Industrial Engineering: Suggested Modification.” Udyog Pragati. October-December 2006. p. 1-4.

Components of Industrial Engineering

Industrial Engineering can be described adequately by three components.
1. Human Effort Engineering
2. Systems Efficiency Engineering
3. Systems Design,  Installation and Improvement Management
In the area of systems design, industrial engineering activities of human effort engineering and systems efficiency engineering are speciality engineering areas. As industrial engineering has a good involvement in the systems design through two important areas and also as industrial engineering is output conscious and profit (value) conscious, IE department can take up the management of systems design activities of an organization. The official definition of IE of IIE provides scope for all these activities by stating that IE is concerned with system design, installation and improvement. It does not emphatically says that IEs design systems. They do number of activities related to systems design especially where multiple resources are involved and in that role human factor definitely demands that IEs are involved in the systems design to eliminate waste related the utilization of human resources.

Marvin Mundel - Industrial Engineer

Different Kinds of Changes

To improve a work method (work system), innovations or changes are necessary in any one of the five areas that affect its performance.
They are:
1. Human activity: The hand and body motions or the perceptive or cognitive activity or their sequence may be changed to ease or improve the task.
2. Workstation (tools, workplace layout, or equipment): The design of any single workstation or the equipment used for any part of the task may be modified.
3. Process or work sequence: The order or condition in which the various work stations receive the in-process output may require change or the number of work stations may be modified.
4. Output design: The product design or the form of goods sold or the material sent out or the nature of the completed service may be changed in order to facilitate the attainment of the objectives of improvement.
5. Inputs: The incoming supplies of raw materials or parts may be changed with respect to the form, condition, specification, or timing of the arrival to allow the desired improvements to be made.
From the list of possible changes, innovations in human activity and work station fall in the domain of human effort engineering

Time Study, Motion Study, and Methods Study

Time study was proposed by F.W. Taylor and as conceptualized by Taylor and it includes methods study and motion study in itself. Frank Gilbreth proposed motion study, but he did use the term methods also in his writings. Gilbreth recognized the contribution of Taylor in proposing in his time study, the study of work at element level. People credit Maynard in developing the concept of method study, to end the differences between followers of Taylor and Gilbreth over time study and motion study.
But as things stand today, we can separate the three. Method study is a study of various operations and their sequence. Methods efficiency design is an evaluation of method proposed by functional designers using method study approach. Each operation is to be performed by an individual man or man-machine system or in some cases by a group of men. Lifting of heavy furniture is an example wherein a group has to carry out an operation. Each operation requires motion design. Data for motion design comes from earlier motion studies and some study conducted as a part of the current motion design. Work measurement is carried out for each operation in an approved method. Work measurement can be carried out using predetermined motion time systems or time studies or work sampling methods as appropriate.

Taylor - A Pioneer in Human Effort Engineering

Henry Towne, Past President of A.S.M.E. in foreword to Shop Management, A Paper of F.W. Taylor, First published in 1910.
The substitution of machinery for unaided human labor was the great industrial achievement of the nineteenth century. The new achievement to which Dr. Taylor points the way consists in elevating human labor itself to a higher plane of efficiency and of earning power.
We are proud of the fact that the United States had led all other nations in the development of labor-saving machinery in almost every field of industry. Dr. Taylor has shown us methods whereby we can duplicate this ahievement by vastly increasing the efficiency of human labor, and of accomplishing thereby a large increase in the wage-earning capacity of the workman, and a still larger decrease in the labor cost of his product.
The Editor of the book Scientific Management, jointly published by Harper & Row, New York and John Weatherhill, Inc., Tokyo, 1911
"The Principles of Scientific Management," is simply an argument for Mr. Taylor's Philosophy of Human Labor, - an outline of the fundamental principles on which it rests.

Matching TRIZ engineering parameters to human factors issues in
DENIS A. COELHO, Department of Electromechanical Engineering
University of Beira Interior, Calçada Fonte do Lameiro, PORTUGAL
Abstract: - An overview of the development of the TRIZ problem solving approach is provided in the first part
of this paper. Having emerged in Russia in 1946, the Theory of Inventive Problem Solving Technique (TRIZ)
has been commonly used in the USA and Europe in the last few decades. TRIZ, as a method, has been used
successfully to solve problems such as many of those typically arising during the process of product
development, as reviewed in the second part of the paper. While the TRIZ method is also considered fit to
address human factors problems in manufacturing, straightforward application would benefit from a resource
gathering supporting knowledge and techniques. In the third part, analysis of previous work leads to suggest that new TRIZ method users might benefit from specific guidance in the interpretation of the engineering parameters in the contradiction matrix, considering human factors problems in manufacturing. A tentative correspondence is proposed in the fourth part between human factors issues in manufacturing and the engineering parameters in the matrix. The paper concludes emphasizing the need to further extract and categorize human factors and ergonomics principles and understand and analyze them under the light of the 40 inventive principles of TRIZ.

Fundamentals of Industrial Engineering

Review of the Chapter 1.5 Fundamentals of Industrial Engineering in Maynard's Handbook of Industrial Enginering, 5th Edition. List of all chapters of the book is available in:
This chapter was written by Philip E. Hicks.

Efficient production system design and efficiency improvement of production systems is the aim of industrial engineering. This fact is brought out by Hicks in the following statement.
A production system is essentially the sum of its individual operations. Therefore, it follows that if one wants a production system to be efficient then its individual operations must be efficient. Working from a bottom-up micro perspective, one approach is to simply review all individual operations to make them the best they can be.  One reason such an approach offers considerable opportunity for improvement today is that it has been often overlooked while the search for the single “silver bullet” macro solution occurs in the front office or the boardroom. In many firms today individual workstation cycle times can be reduced by one-third to one-half of their present average cycle times by implementing a short list of modest improvements in these workstations.

Hicks has given following areas as fundamental areas of industrial engineering

Methods Engineering
Work Measurement
Facilities Planning and Design
Material Handling

Inventory Control
Quality Control

Team Based
Continuous Improvement

According to me operations management is not any more an area reserved for industrial engineering. Operations management has evolved as an independent subject area within the discipline of business management and industrial management. Operations control is a sub-area within operations management.

Industrial engineering has to focus on two areas as its specialty – Human effort engineering and System efficiency engineering. By inserting the term efficiency and writing the first area as OPERATIONS EFFICIENY ANALYSIS AND DESIGN will be make it more clear to the practitioners as well as users the role of industrial engineers. Work measurement is an exclusive area of industrial engineering and we need to recognize that in methods engineering once again functional engineering of the method belongs to production engineers and only human effort and efficiency engineering are the areas of industrial engineering. Ergonomics is the science used by industrial engineering in human effort engineering.

Focus of Industrial Engineering is Human Efficiency and System Efficiency in the design of integrated systems.

They are Efficiency Experts and They are not Functional Designers or Experts.
The Two Important areas of IE are Human Effort Engineering and Systems Efficiency Engineering. 



Institute of Industrial Engineers, the global professional body of industrial engineers provides the following definition for their discipline. Industrial engineering is concerned with the design, improvement, and installation of integrated systems of people, material, information, equipment, and energy. It draws upon specialized knowledge and skills 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 systems1.

The definition does not provide the focus of industrial engineers. The curriculums and text books of the discipline also do not provide its focus clearly. Due to this shortcoming, there is an identity crisis in the profession and may people with qualifications in industrial engineering join other departments where focus is more clear and shun industrial engineering as a career. Could industrial engineering discipline discover its focus?

For this endeavor one may start by examining the evolution of Industrial engineering.

Evolution of Industrial Engineering

The earliest reference to Industrial Engineering that we could trace was the address delivered by Henry R. Towne2 at the Purdue University on February 24th, 1905. According to him,” the Engineer is one who, in the world of physics and applied sciences, begets new things, or adapts old things to new and better uses; above all, one who, in that field, attains new results in the best way and at lowest cost.”

Towne explained that Industrial Engineering is the practice of one or more branches of engineering in connection with some organized establishment of a productive character, in which are conducted the operations required in the production of some article, or series of articles, of commerce or consumption.

He emphasized that an engineer who combines in one personality the two functions of technical knowledge and executive ability   has open to him unlimited opportunities in the field of industrial engineering. F.W.Taylor is hailed as the Father of Industrial engineering. He focused on improving the output from persons working in various trades. Time study was his main technique. Gilberth brought in the technique of motion study and developed the science and art of improving human efficiency at work. Harrington Emerson independently developed the ideas of efficiency of business organizations and published the book "The Twelve principles of Efficiency.3" He was one of the founding members or organizers of  "The Efficiency Society," which was started in 1912. Taylor Society and the Efficiency merged at a later point in time. Taylor's and Emerson's efforts in promoting human efficiency and system's efficiency form the back bone of the current profession of Industrial engineering. 

Lehrer's Definition

Robert N. Lehrer, Editor-in-chief of the Journal of Industrial Engineering, had proposed the following definition for industrial engineering in 1954. “Industrial engineering is the design of situations for the useful coordination of men, materials and machines in order to achieve desired results in an optimum manner. The unique characteristics of Industrial Engineering center about the consideration of the human factor as it is related to the technical aspects of a situation, and the integration of all factors that influence the overall situation.”4

The definition proposed by Lehrer brought out the importance of human factor specifically. But this definition was modified by AIIE  to broaden it to a large extent. But in that process the focus was lost. Narayana Rao examined this problem and proposed the following definition5.

Definition by Narayana Rao


“Industrial Engineering is Human Effort Engineering. It is an engineering discipline that deals with the design of human effort in all occupations: agricultural, manufacturing and service. The objectives of Industrial Engineering are optimization of productivity of work-systems and occupational comfort, health, safety and income of persons involved.”

The proposed definition basically extends Lehrer’s definition and captures the work done by Taylor and Gilbreth. Both of them studied human effort in detail and optimized the work system. Industrial engineers will bring to the design of large production system like a factory, their specialized knowledge of the human effort and human factors, methodology of studying work, and work measurement. Industrial engineers will also have adequate knowledge of technologies and equipment being used in the factory and the business principles and implications. While the knowledge of the human effort, human factors, methodology of studying work, and work measurement are the common knowledge areas of industrial engineers, the technology specific to the various industries will be different and thus specialist industrial engineers will emerge for different industries. It is also in line with the practice of admitting engineers of all disciplines in post graduate programs of industrial engineering.
In the case of engineering disciplines, industrial engineers are concerned with those situations in engineering practice where there is involvement of people in production, installation or maintenance and they will do an advanced study of features of equipment, with which people interact and operate the equipment. Already industrial engineers are working in various areas where traditional engineering disciplines have no role like banks and hospitals. Redefining Industrial Engineering as Human Effort Engineering, explains the role, industrial engineers are performing currently in a wide variety of organizations. Also, the word ‘industry’ has the meaning of effort or sustained effort in English language. Thus, we are making the definition of Industrial Engineering easy to be comprehended by even ordinary persons. 
The objectives of Industrial Engineering are mentioned as optimization of productivity of work-systems and occupational comfort, health, safety and income of persons involved. Taylor examined all the three simultaneously in his work design efforts. Taylor became the target of criticism because at that point of time, his conclusion was that workers were capable of more output but they were not producing to their full potential. But still the objective of Taylor was not to squeeze production from workers for the benefit of managements. Industrial Engineering should be so defined and practiced that industrial engineers are invited by employees themselves to examine their work and improve their productivity. The improvement in productivity should not lead to additional discomfort to the employee. Actually, the study by an industrial engineer should lead to more comfort for the employee. The increases in productivity should always lead to increase in income of the employees concerned or in other terms wages and salaries should reflect productivity differences among employees. Then employees themselves will invite industrial engineers to help them to improve their productivity as well as comfort. Even a self-employed person should invite industrial engineers to come and study his work and redesign it to optimize his comfort, productivity and income.
The objective of optimization of productivity of work-systems captures the direction and effort of Harrington Emerson. Industrial engineering has many efficiency improvement techniques.
Industrial engineers have to focus on human efficiency and system efficiency in the design of integrated systems and they can look for a leadership role in the systems design due to their broad learning curriculum.

Some views and practices that support the view expressed in this article

Central to the discipline of industrial engineering are two themes: the interfaces among people and machines within systems, and the analysis of systems leading to improved performance. These issues motivated Taylor, and they motivate us today.

Human effort engineerng and System efficiency engineering can be identified in the above two themes.
