MTM-1 用于工裝或機械設計， 無疑會讓設計更加貼近實用和經濟。與人機工程也相關。

 

Method-Time Measurement

The basic MTM data was developed by HB Maynard, JL Schwab and GJ Stegemerten of the Methods Engineering Council during a consultancy assignment at the Westinghouse Brake and Signal Corporation, USA 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 MTM spread, firstly in the USA and then to other industrialised 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.

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.
