What is Work Sampling (Multimomentanalysis) ?
Work sampling is the statistical technique for determining the proportion of time spent by workers in various defined categories of activity (e.g. setting up a machine, assembling two parts, idle…etc.). It is as important as all other statistical techniques because it permits quick analysis, recognition, and enhancement of job responsibilities, tasks, performance competencies, and organizational work flows. Other names used for it are 'activity sampling', 'occurrence sampling', and 'ratio delay study'.
In a work sampling study, a large 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 period must be representative of the types of activities performed by the subjects.

work sampling today - self administered
The default definition of work sampling is marked by foreign-obervations, this means observations by other people. This is good for manufacturing processes but in newer times self-administered observations are more useful because of technical options given e.g by smartphones or web techniques. This makes using activity sampling methods for services also possible.
By using this it is possible to get more accurate data about the timing of events as this would ever be possible by foreign observation. Intellectual activities, more precise verification of work steps, measurements at different workplaces and even measurements across site boundaries are now possible and allow a better insight view of the company.
During the sampling study, the participants are asked the previously defined questions at random intervals in a minimally invasive manner. By using smartphones, these questions can be asked independently of local conditions and can be answered at any time and any place.
The use of modern technologies in combination with a proven method creates completely new ways of obtaining information within the organisation.
