A predetermine motion time system (PMTS) is frequently used to set labor rates in labour oriented industry by quantifying the amount of time required to perform specific tasks.

• The first such system is known as methods-time measurement,released in 1948 and today existing in several variations, commonly known as MTM-1, MTM-2, MTM-UAS, MTM-MEK and MTM-Qbsolete MTM standard include MTM-3 and MMMM(4M).
• The MTM-2 standard has also largely been phased out by the organisation, but is still used in some commercial applications.predetermined motion time system is another term to describe predetermined time standard(PTS)
• PREDTERMINED MOTION TIME STANDARDS are also referred as predetermined time standard(PTS). PMTS defines the time needed for the performance of various motions and not by direct observation and measurement.
• According to ILO, a predetermine time standard is a work measurement technique, whwre time established for basic human motions are used to build up the time for job at a defined level of performance.
• In PMTS, the operation being measured is divided into basic motions to adjust the performance level of organization and add allowances in time study as PMTS do not include allowances. The work study by industrail engineer, encounters different forms of PTS system.
