Methods-time measurement

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, to set the standard time in which a worker should complete that task.

MTM was released in 1948 and today exists in several variations, known as MTM-1, MTM-2, MTM-UAS, MTM-MEK and SAM-analysis. Some MTM standards are obsolete, including MTM-3 and MMMM (4M).

MTM does not make use of a stopwatch or time study and therefore also negates the need for pace rating.

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, first 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.

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. The original MTM system is now commonly referred to as MTM-1. Other systems based on MTM have been developed for particular work areas by National Associations. The most recent development is MTM-UAS, created by a consortium from the German, Swiss and Austrian National Associations during the mid 1970s. In 1975 the Nordic MTM Association developed and launched MTM-SAM, the third generation of MTM technique.

In 2020 the IMD was terminated and dissolved, and the members split into two groups. The majority of the members (Germany, United States, Italy, Benelux, Brazil, Czechia, Slovakia, China, Hungary, Mexico, South Africa, Austria, Poland and United Kingdom) formed the One-MTM network, headquartered at the MTM ASSOCIATION e.V. in Hamburg, Germany. The minority members formed a new non-profit organization: IMD-EWD was founded by MTM associations Nordic, France, Spain, Turkey and Switzerland.
