Document Summary
Used to estimate the standard time required to perform a job. Standard time: the time required by an average worker to perform a job once. This is called line balancing (assigning the same amount of work at each work station) Stopwatch time study -- basic steps: establish the standard job method, break down the job into elements, observe (time) the job, rate the worker"s performance (rf) average worker rf = 1. 0. Rf > 1. 0: compute the average elemental time ( t , compute the normal time. Where elemental normal time = nt = ( t )(rf: compute the standard time. Standard time = (normal time) (1 + allowance factor) Bit 3414 copyright 2017: 1, use the standard time for production calculations. Stopwatch time study example: a baseline time study has been conducted for a workstation that assembles bouquets of flowers. Element: prepare wrapping, select flowers, arrange flowers, place in box. 0. 0967: select flowers, arrange flowers, place in box.
