observed time

observed time

the time it takes an operator to perform a task when being observed for time study purposes. Observed times do not take into account contingencies like machine breakdowns or the operator's ability, and are simply the time taken by the particular operator being observed to complete the task. Thus, when setting a STANDARD TIME for a particular task several different operatives of differing levels of ability will be observed, and a contingency ALLOWANCE added. See WORK MEASUREMENT.
