1 – Introduction to measuring working time

We wanted to study and optimize work at all times. With the improvement of technologies and the conclusion of research, there are four main methods for evaluating working time.

2 – Time study

Based on a real observation of the work, it allows to identify the standard times as well as potential improvements.

3 – Standard data

One of the techniques of time study, standard data consists in the construction of a time data bank.

4 – Work sampling

Based on a statistical analysis of frequencies, this method allows to determine operations times by freeing of technical difficulty or judgement.

5 – Pace judgment

The pace judgment is a subjective assessment of the relative rate of work observed. The analyst compares the observed operator’s performance with a concept of normality.

The MTM 1

MTM is the most well-known predictive method of time. Widespread in the industry, particularly automotive, it originated in the early 20th century.

The MTM 2

Evolution of the MTM1, the main challenge of the MTM2 is to simplify the system and reduce the time of analysis while maintaining a good accuracy.

The MTM 3

The third evolution of the MTM, it aims once again to reduce the processing times of the measures


With this new version of the MTM, the goal is to make it the fastest MTM system.

The BasicMOST

The MOST is a method of predetermination of time. Simpler and above all faster than MTM, it is based on standard sequences and the fact that most of the work is done with objects.

The MiniMOST

The MiniMOST is suitable for very repetitive and precise movements.

The MaxiMOST

Unlike the most, this version has been developed for less repetitive activities (less than 150 times per week), lasting from 2 minutes to several hours and based on operations ranging from 2 minutes to more than 10 minutes.

Comparison of methods of predetermination of time

The MTM and other prédétermimation tools are very powerful tools but require a great deal of knowledge and rigour in its application. Below we propose a comparison between different of these methods.
