Industrial Engineering.
One could define "INDUSTRIAL  ENGINEERING" as: The science or knowledge to produce products with wanted quantities and the demanded quality at the suggested cost price without harming the well-being of employees.
	It has no doubt that the operational approach of  Industrial engineering has a social impact on the workers.   Besides the demands of the market or the clients it is vital to bring the comfort of the workers to a accepted standardized level.    The first to apply this in practise was Winslow Frederick Taylor.   He was an engineer in the beginning of the 19th century and understood that increased product output could not be a result of harder working but must be achieved by changing and approving the method of working which is the responsablity of the Industrial Engineer.  He formulized 2 one-liners and as such defined the code of Industrial engineering. The one best way to do the Job A fair day's work for everybody. Every current and present engineer will find in these  2 sentences the moral and sience in performing daily Industrial Engineering.
	Although Taylor left us clear ethic rules the basis of methods improvement or reorganizing was done by his colleague Frank Gilbreth. He invented a system to analyze and categorize the methods of working in detail called "Therbligs". By doing so Gilbreth defined the fundaments of modern time study systems and INDRUSTRIAL ENGINEERING. The therblig system of Gilbreth allowed us to scientifically categorize and organize work. His succeeders added predetermined timestudy to measure the catgories as he defined in the therblig system. Maynard & Quick the inventors of the future time study systems MTM en workfactor used a modified theory of Gilbreth as a corner stone of there  design.
