Predetermined time systems

A predetermined 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-B. Obsolete MTM standards include MTM-3 and MMMM (4M). The MTM-2 standard has also largely been phased out by the organization, but is still used in some commercial applications. Predetermined motion time system is another term to describe Predetermined Time standards (PTS).

Another popular PMTS is the Maynard Operation Sequence Technique, which was first released in 1972. H.B. Maynard was acquired by Accenture in 2007. That method also has several variations, with the most commonly used being BasicMOST, and others being MiniMOST, MaxiMOST, and AdminMOST. The variations of both systems differ from each other based on their level of focus. MTM-1 and MiniMOST are optimal for short processes with only small hand motions. BasicMOST, MODAPTS and MTM-UAS are more suitable for processes that average around 1 to 5 minutes, while MTM-B and MaxiMOST are more properly used for longer processes that are less repetitive.

Yet another popular PMTS used today in the automotive, sewing and healthcare industries is the MODAPTS technique. This technique was introduced in 1966 by G. C. "Chris" Heyde who originally learned the MTM-1 and MTM-2 methods in the 1950s and sought a simpler technique to use and apply. Unlike the MTM and MOST standards, MODAPTS uses a MOD as its basic unit of measurement (1 MOD = 0.129 seconds). However, like Basic-MOST, MODAPTS uses a coding technique that consists of a letter and an integer number (all but 1 code), where the integer numbers each represent MODS that can be easily added to determine a coded task's time.

MODSEW is a software application of MODAPTS for the sewn products and apparel industries. It uses very intuitive codes to represent the various motion patterns prevalent in the industry and allows the user to configure their own codes for those unique to their operation. The software is used to determine the standard time to complete an operation and has provisions to collect and maintain groups of operations in a style (product). MODSEW is owned, maintained, sold and supported by Byte Software Services, LLC of Mauldin South Carolina.

General Sewing Data is a PMTS for the sewn products and apparel industries and is based on MTM Core Data both proprietary data systems of GSD (Corporate) Ltd of Preston, UK. The Time standards for General Sewing Data are used in GSD Enterprise and GSD QUEST. GSD company was taken over by thread giant Coats in 2015.
