The principles explain the question what is industrial engineering (IE)?
Basic Principles of Industrial Engineering - Narayana Rao
1. Develop science for each element of a man - machine system's work related to efficiency and productivity. (Productivity Science)
2. Engineer methods, processes and operations to use the laws related to the work of machines, man, materials and other resources. (Productivity Engineering)
3. Select or assign workmen based on predefined aptitudes for various types of man - machine work. (Productivity Management)
4. Train workmen, supervisors, and engineers in the new methods, install various modifications related to the machines that include productivity improvement devices and ensure that the expected productivity is realized. (Productivity Management)
5. Incorporate suggestions of operators, supervisors and engineers in the methods redesign on a continuous basis. (Productivity Management)
6. Plan and manage productivity at system level. (Productivity Management)
(The principles were developed on 2 July 2016 at Kakinada, Andhra Pradesh, India (During Birthday break of 2016 - 30 June 2016 to 7 July 2016). Jyeshta Month https://www.drikpanchang.com/panchang/day-panchang.html?date=02/07/2016
The principles were developed by Narayana Rao based on principles of scientific management by F.W. Taylor)
Principles of Scientific Management - Taylor
The managers following scientific management thought do the following things.
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.

What is new in the principles of industrial engineering when compared to principles of scientific management?
1. Develop science for each element of a man - machine system's work related to efficiency and productivity.
Based on the developments in the field of industrial engineering so far, the principle now extends the development of science of areas not so far developed to use of all resources used in the man - machine systems.
2. Engineer methods, processes and operations to use the laws related to the work of machines, man, materials and other resources.
This principles brings out the engineering activity in industrial engineering. Industrial engineers are engaged in applying the scientific laws developed (efficiency and productivity science) to man - machine systems. They develop convenient ways of creating both causes and effects included in the laws of efficiency/productivity science. They have to first redesign methods, processes and operations to incorporate the laws for the first time. Then they have to increase the effectiveness and efficiency of these redesigned methods/processes/operations on a continuous basis.
3. Select or assign workmen based on predefined aptitudes for various types of man - machine work.
Based on the redesigned methods, they have to specify the special aptitude required in operators to become part of man - machine system. Natural aptitude for physical effort, skill of using body parts and senses have to be specified and knowledge of the machine to be operated is also to be specified. Operators are selected based on the specifications.
4. Train workmen, supervisors, and engineers in the new methods, install various modifications related to the machines that include productivity improvement devices and ensure that the expected productivity is realized.
Industrial engineers have to become active members of installation teams and they have to train all persons directly involved in implementing new methods. The persons to be trained include engineers, supervisors and operators. Industrial engineers have to ensure that the expected productivity improvement takes place after the new method is implemented. So they have to measure the actual productivity.
5. Incorporate suggestions of operators, supervisors and engineers in the methods redesign on a continuous basis.
We all now know that there is learning effect. Every body finds ways of improving the work he is doing and managing. Industrial engineers have to recognize this fact and invite suggestions from all on a continuous basis and improve their redesign based on laws of productivity science related to specific man-machine systems.
6. Plan and manage productivity at system level.
The name of the professional body IIE was changed to IISE only to reflect this principles. Industrial engineers have to focus on system level productivity. In any organization productivity improvement is to be planned at organization system level. Even though improvement has to take place at one man, one machine or one man-one machine level, the impact of the proposed changes at the system level has to be estimated by industrial engineers and implementation decisions have to be taken based on the system level benefit. Similarly measurement of the benefit after implementation has to be done at system level.

INDUSTRIAL ENGINEERING is redesign (engineering) of Products, Facilities and Processes for Productivity increase (IISE Augmented Definition for Other Results Areas).
(C) Narayana Rao K.V.S.S. 2016,
see the article by David Scott Sink et al.
Manage of systems under the role of industrial engineer have to keep in mind systems contain systems. Most are not taught, therefore do not do, management/training system maintenance. For example when designing machine control code, do not consider who will be maintaining their code for the next 10-20 years, maintenance. (REF: http://plc-training.org ) They are not taught in school, maintenance end-users will have to maintain their code, long after they have made it past the start-up, commissioning phase, so they should place priority on end-user simplicity when writing machine control code, instead of placing their priority on making their own job easier (first 3-5 years of life cycle), instead of end-user maintenance's job easier (5-20 years of life cycle). This global industry shortcoming's comes from colleges not covering and/or not covering extensively enough Equipment/system life cycle management principles.
