Methods design, motion and time study

What’s methods design

Methods design is the analysis of the various ways a task can be done so as to establish the one best way. It includes motion analysis (the study of the actions the operator can use and the advantages and/or disadvantages of each variation) and standardization of procedure (the selection and recording of the selected and authorized work methods).

While ‘‘time and motion study’’ is the more commonly used term, it is more correct to use ‘‘motion and time study,’’ as the motion study to establish the standard procedure must be done prior to the establishment of a standard time to perform that work.

Motion study definition

Motion study can be defined as “the analysis of the manual and the eye movements occurring in an operation or work cycle for the purpose of eliminating wasted movements and establishing a better sequence and coordination of movements.”

Time study definition

Time study can be defined as “the procedure by which the actual elapsed time for performing an operation or subdivisions or elements thereof is determined by the use of a suitable timing device and recorded. The procedure usually but not always includes the adjustment of the actual time as the result of performance rating to derive the time which should be required to perform the task by a workman working at a standard pace and following a standard method under standard conditions.”

Attempts have been made to separate the two functions and to assign each to a specialist. Although motion study deals with method and time study deals with time, the two are nearly inseparable in practical application work. The method determines the time required, and the time determines which of two or more methods is the best. It has, therefore, been found best to have both functions handled by the same individual.
