Work study can be divided into method study and work measurement.
It is used to systematically study and improve human working methods by considering all factors that affect the working efficiency and conditions.
After the job of interest has been selected, time study can be examined by
1) recording all information about the job,
2) breaking the job down into elements,
3) examining those elements and
determining the sample size,
4) recording the time to perform each element using a stop-watch,
5) assessing the speed of working,
6) converting the observed time to basic time,
7) determining the allowances,
and 8) determining the standard time.
