Predetermined Motion time System ( PMTS):
Predetermined motion time system is defined as a work measurement techniques by which normal or basic times are established for basic human motions and these time values are used to build up the time for a job at a defined level of performance.
It is a work measurement techniques that involves observing or thinking through a job recording job elements recording pre established motion units and calculating a performance standard.
PMTS is an improvement over motion study because besides affording detailed analysis of the motion it makes it possible to set a measure of the time that a series of motion ought to take.
