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 minority members formed a new non-profit organization: IMD-EWD was founded by MTM associations Nordic, France, Spain, Turkey and Switzerland.
One-MTM partners develop MTM products and services in the fields of training, consulting, software and research and ensure their uniform application and dissemination worldwide.
Films were taken using constant speed cameras, running at 16 frames per second, of the work performed by qualified workers on the shop floor at the Westinghouse Brake and Signal Corporation.
Layout, distances, sizes of parts and tools and tolerances were accurately measured and recorded on the shop floor to complement the later analyses.
This allowed a time for each recorded motion to be calculated in seconds, by means of a frame count, and then “levelled” to a common performance.
Detailed research conducted under the auspices of the USA / Canada MTM Association have resulted in minor changes to the data and the application rules and in a greater understanding of the nature of the motions.
Many contributions were developed in the area of MTM, more recently 2019-2020, a team from University of Pisa collaborated with an Italian company developed an automated system called Method Time Measurement 4.0 (MTM4.0) aligning with Industry 4.0 concepts and enabling technologies such as Industrial Internet of Things (IIoT) and Radio Frequency IDentification (RFID), the work of the team is published in International Journal of Productivity and Performance Management.
