MTM is a complete system to design a productive and healthy work environment for production, Logistics, services, organisational institutions and offices, in general. MTM is suitable for employee management and process planning, by analytical work mode and its uniform basic performance. MTM is a worldwide, most spread and recognized process building block system
Definition of MTM
MTM (Methods-Time Measurement) is a job analysis technique, with which the human labour can be decomposed into motions, which are needed for implementation. For this purpose, time standards are established, depending on the nature of the motions and the conditions, under which these are carried out.
Practice of MTM
The MTM-methods were developed for mass- to single piece production. Either short and long cyclic work. For each method level, or process type, is a suitable method available. In addition, MTM-methods are developed for Product development (effective Assembly method by a points system), Ergonomics, Visual inspection and Logistics.
Level of performance level MTM
MTM (published in 1948) is a PTS (Predetermined Time System) system, developed by Maynard, Stegemerten and Schwab from the Methods Engineering Council Pittsburg US.
When the level of performance for MTM – 1 was established, they used for example the LMS system, developed by Lowry, Maynard and Stegemerten (Westinghouse), with the following levelling factors
– skill (proficiency);
– effort (will to work);
– consistency (variability).
These factors show plus or minus values relative to a normal performance (100%). These represent a typical and average production worker with routine. The MTM-1 time values are brought to an equal level with LMS 100%.
All later developed MTM-systems are based on MTM-1 and are therefore classified at the same level of performance.
Basic principles of the MTM-Methods
Limitations of the MTM-methods
- The definition makes it clear that the MTM methods are limited to complete influenceable (manual) operations. Times for limited influenceable and not influenceable processes are generally determined by time recordings, either calculated
- The MTM-method cannot be used for mental activities when there is a desire for more than simple Yes or No decisions. Common thinking can therefore not be analysed.
- Allowances and resting periods are not included in the MTM-standard times. These are processed through the usual methods for labour-and time studies.
Advantages of the MTM methods, in comparison to other time-determining-techniques
- Work methods and set-up and run times can be defined in detail before the start of the production. The manufacturing steps and work content can be secured at the first time.
- MTM requires the user to define the work methods in detail for a clear time determination. By critically analysing the developed methods, the best method under the given conditions, can determined while still in the planning stage. This lead to better qualified employees.
- It follows the principle of work process planning using MTM-methods:
“Cost reduction through additional work design” is replaced by
“Cost avoidance through prior sequence planning.”
- The uniform coding of motion elements leads to an internationally accepted, reproducible description of the work process, which is particularly important for developing planned times.
- Because of experiment of assessing the pace, necessary for chronometer recordings, a guarantee for time standards in a uniform performance level is given in bigger extent.
- When setting up the schedule for time determination, the required influence factor calculations expire during the time measurement with the chronometer, because the MTM-time standards have been drawn up already with the relevant influence factors.
- A computer-assisted application allows a fast, reproducible development and management of time building blocks possible. This makes direct adjustments to changes or new processes possible, to keep the planning up to date as simple as possible.
- Employees can be initially trained to follow the planned methods reflected in the MTM analyses, thus reducing the associated learning curve to a minimum.
- Application of the MTM method for calculating standard times makes introduction of incentive pay This leads, in case of objections, to a more objective, method oriented, discussion.
- Working methods are always reproducible, because the exact work process is documented.
- The combination of MTM and the Lean concept is successful at avoiding waste.
- MTM is also an excellent tool to, for example, Value Stream Mapping (VSM)
MTM Association Benelux is a continuation of the Belgian and Dutch MTM Associations. The latter is raised from the Dutch MTM-Fellowship, which was founded in December 1952. This Institute was one of the founding members of the International MTM Directorate (IMD). Founded in 1968. From the beginning, the Belgian and Dutch MTM Associations have been a member of the IMD. After 2000 are both associations merged. Shortly thereafter, the Board expanded by a representative of Luxemburg.
MTM Association Benelux
We are the are the MTM-licensee of Belgium, Luxembourg and Netherlands. Trainings and exams are internationally recognised. Trainings and exams are internationally recognised. The diplomas of trainings, which are covered by the so called Technical Platform of the IMD, are awarded with an addition unique seal. In the current Board is at least one Board member from one Benelux country.© MTM Association Benelux 2017/06
