Industrial Engineering - Its Role in Productivity Improvement
Two important components of industrial engineering are System Efficiency Engineering and Human Effort Engineering.
We can say System Industrial Engineering and Human Effort Industrial Engineering.
Industrial Engineering Definitions
“Industrial engineering is the engineering approach applied to all factors, including the human factor, involved in the production and distribution of products or services.” (Maynard, 1953) 
"Industrial engineering may be defined as the art of utilizing scientific principles, psychological data, and physiological information for designing, improving, and integrating industrial, management, and human operating procedures." (Nadler, 1955) 
“Industrial engineering is that branch of engineering knowledge and practice which
1. Analyzes, measures, and improves the method of performing the tasks assigned to individuals,
2. Designs and installs better systems of integrating tasks assigned to a group,
3. Specifies, predicts, and evaluates the results obtained.
Narayana Rao (2009)
Total Industrial Engineering is "a system of methods where the performance of labor is maximized by reducing Muri (unnatural operation), Mura (irregular operation) and Muda (non-value added operation), and then separating labor from machinery through the use of sensor techniques." (Yamashina)
