. Work Sampling

Work sampling may be defined as a statistical technique used to determine the amount of time spent by an employee in performing a variety of different activities . It is used to investigate the proportion of total time devoted to various activities that constitute a job or work situation . The results of work sampling are used to determine machine and personnel utilization, allowances applicable to the job and production standards . Work sampling frequently provides the same information faster and costs considerably less than time study . Work is analyzed by taking a large number of observations at random intervals of time . The accuracy of the data determined by work sampling depends on the number of observations and the period over which the random observations are taken . Work sampling studies rely on a large number of observations obtained at random intervals of time . The ratio of observations of a given activity to the total number of observations is an approximation of the total percentage of time that the process is in that state of activity .
