Time study is a structured process of directly observing and measuring (using a timing device) human work in order to establish the time required for completion of the work by a qualified worker when working at a defined level of performance. It follows the basic procedure of work measurement of analysis, measurement, and synthesis. The observer undertakes preliminary observation of the work (a pilot study) to identify suitable elements that can be clearly recognized on subsequent occasions and are convenient, in terms of their length, for measurement. Subsequent studies are taken during which the observer times each occurrence of each element (using a stopwatch or other timing device) whilst at the same time making an assessment of the worker's rate of working on an agreed rating scale. (One of the prime reasons for measuring elements of work, rather than the work as a whole, is to facilitate the process of rating. The rate at which a worker works will vary over time; if elements are carefully selected, the rate of working should be consistent for the relatively short duration of the element.) This assessment of rating is used to convert the observed time for the element into a basic time – a process referred to as “extension.” It is essential that a time study observer has been properly trained in the technique and especially in rating. The technique, when properly undertaken, ... log in or subscribe to read full text
