Work sampling is the statistical technique for determining the proportion of time spent by workers in various defined categories of activity. It permits quick analysis, recognition, and enhancement of job responsibilities, tasks, performance competencies, and organizational work flows.
In a work sampling study, a number of observations are made of the workers over an extended period of time. For statistical accuracy, the observations must be taken at random times during the period of study, and the sampling must be representative of the types of activities performed by the subjects.
Recording such observations can be easily done via simple mobile-based applications. Further, the observations can be tagged with appropriate meta-data like location and/or multimedia collateral to enable better drill-down and analysis in the future.
