Methods-time measurement
Summary
Methods-Time Measurement (MTM) is a predetermined motion time system that is used primarily in industrial settings to analyze the methods used to perform any manual operation or task and, as a product of that analysis, set the standard time in which a worker should complete that task.
MTM was released in 1948 and today exist in several variations, known as MTM-1, MTM-2, MTM-UAS, MTM-MEK and MTM-SAM. Some MTM standards are obsolete; including MTM-3 and MMMM (4M).
The basic MTM data was developed by H.B. Maynard, JL Schwab and GJ Stegemerten of the Methods Engineering Council during a consultancy assignment at the Westinghouse Brake and Signal Corporation, United States in the 1940s. This data and the application rules for the MTM system were refined, extended, defined, industrially tested and documented as a result of further work in later years.
In 1948, Maynard, Stegemerten and Schwab published the book “Methods-Time Measurement” giving full details of the development of the MTM system and its application rules. The use of Methods-Time Measurement MTM spread, firstly in the USA and then to other industrialized countries. In 1951 the USA / Canada MTM Association for Standards and Research was formed by MTM Users. The system originators then assigned the MTM copyrights to the MTM Association. Other national MTM Associations were founded and, at a meeting in Paris in 1957, it was decided to form an International MTM Directorate (IMD) to co-ordinate the work of National Associations. National MTM Association members of IMD now hold the MTM copyrights for their territorial areas.
In 2020 IMD was terminated and dissolved. A new non profit organisation, IMD-EWD was founded by MTM associations Nordic, France, Spain, Turkey and Switzerland. IMD-EWD (International Motion Time Measurement - Ethical Work Design) continue to cover, prove, develop and certify all training materials for MTM techniques.
Other MTM based systems have since been developed. MTM-2, a second generation system was developed under IMD auspices in 1965; MTM–3, a further simplification, was developed in 1970.
