Time Study - Work Measurement
Engineering tasks are to be divided into elementary operations or elements, and the time to complete them has to be understood through various elements contributing to it. Through that understanding the time to do an element has to be reduced. These elements have to be classified into standard elements that are present in multiple tasks.
Time study has to be done at the start of the process improvement study. At intermediate points in the study. At the end of the study. Then after some training and practice in the new method, it has to be done to fix the output expected from the new process as standard.
Taylor's Time Study: Taylor wanted time study to generate standard data for specified elements of work of machines and men. This standard data can be at national or universal level, industry level or company level. Taylor and Gilbreth recommended study of the best person to understand the best way of doing a work element. They spent time to further improve the way of doing based on productivity science developed them on the work element. For them the output of time study has to be the best way of doing a work element and the minimum time in which it can be done. Taylor insisted from the beginning that the speed specified for operations has to be the speed that can be done comfortably, safely and healthily for the entire career span of the operators. What is that speed? Industrial engineering discipline later on developed a standard for that speed as 3 miles per hour. But is it scientifically validated? It may be necessary to provide solid logic and empirical foundation for this standard. Do people feel happy and comfortable to walk 24 miles per day in 8 hours? This standard has corresponding specification in various work elements. In which work element, people are happy and comfortable to do as per the standard? It is an important question to be answered IE discipline.
