Meaning and Definition
Motion study is formal engineering analysis of motion perform to accomplish work. The motion or movements of limbs of a worker play a major part in the fabrication or the manufacture of the products. By carefully observing a worker while he is doing an operation a number of movements made by him which appear to be unnecessary and unproductive can be identified and eliminated.
According to Alford and Beatty " Motion study consist of dividing work into the most fundamental elements possible studying these elements separately and in relation to one another and from these studied elements when timed building methods of least waste"
Analysis of an operation when carried out in terms of individual motions of a worker is known as motion analysis.
Motion study techniques for methods analysis are an important contribution of the Gilbert to industrial management.
The purpose of motion study is to design as improved method which eliminates unnecessary motions and employs human efforts more productively. In doing so the principles of motion economy proves to be very helpful.
