The five afore mentioned WORK-FACTOR systems DWF, RWF, AWF, VWF and BWF, are suitable mainly for the analysis of manual motions and actions. For mental processes they offer very limited possibilities. Even then, the limitation in use, is that the mental processes analyzed must be just a small part with respect to the total manual actions within the totality of the process or task to be analyzed.
However, when activities must be performed which consist for a large part or (almost) totally of mental processes, as is the case with visual inspection, than a Mento-Factor system should be applied.
Detailed Mento-Factor, MF, has as its time unit the Time Unit, TU, just like DWF, measured in 0,0001 minute, so 10.000 TU = 1 minute. Finished and published in 1960.
The intrinsic tempo is tempo 78 Bedaux or 98 BSI or 130% (ASME)..
Mental processes are very complicated and complex. With MF “rather simple” mental processes can be analyzed. It will be clear, that with MF it is not possible to determine the time to learn a poëm by heart.
Mento-Factor has 13 standard elements and the tables has in total almost 300 time classes.
It takes a lot of time to learn (to be able) to analyze mental labour using the MF system: the education and training time is about 12 to 14 days, dependant on the introductory knowledge, plus almost a day for the MF-examination.
Detailed Mento-Factor is a system developed by the WOFAC/Science Management Corporation, and designed to be able to analyze mental processes as these are taken place in the human body especially in the brains. Gratefully, use is made of the knowledge, experience and data of laboratory for applied physiology in Europe and the USA. Dedicated complementary research was executed at the laboratories of the WOFAC/Science Management Corporation. Testing and improving in practise of the basic data and gathering new information from research at the University of Dortmund, Germany. Combining all this information resulted in the basic values, which were tested on all kinds of work and tasks inwhich the thinking process was dominant, like work in offices, factories and inspection departments.
It comprises the following aspects a.o.:
• collecting information via the senses, f.i. the eyes and the ears,
• recognizing and organizing this information in and by the central nervous system (the brains),
• deciding on basis of this recognized information and coordination of the resulting reaction.
It is not known to us if Mento-Factor software is available.
