WORK FACTOR

The WORK-FACTOR system is one of the oldest systems of predetermined times (SVZ). It thus provides a method for the analysis of work processes is.

history

Originally around 1910 , the American Frank Bunker Gilbreth dealt with the subject of human movement . Segur continued his work with the development of " Motion-Time-Analysis " (MTA). MTA became known in 1924 and is considered to be the oldest elementary time process still used industrially today.

Based on this, Joseph Quick developed the WORK-FACTOR system, which was extensively tested in 1938 and introduced in industry in 1946. In 1958 REFA took over the process in Germany under license. In 1964, the activities were transferred to an independent, registered association, the WORK-FACTOR community for Germany, which has been the sole representative of the system in German-speaking Europe since 1973. In 2003 the cooperation with REFA was revived. International Industrial Consult IIC AG has been the cooperation and marketing partner since 2007.

Over the years the WORK-FACTOR process has lost more and more ground against the simpler and better marketed MTM and is now a niche player.

Procedure

A total of six variants of the procedure, tailored to specific applications, are distinguished: the basic procedure (WFG), the rapid procedure (WFS), the short procedure (WFK), the block procedure (WFB) and the Mento basic procedure (WFM) designed for intellectual work. and Mento-Compact (WFMC).

WORK-FACTOR describes the basic procedure as follows: “The WORK-FACTOR basic procedure enables a detailed analysis of the movement sequence with regard to the movement elements and their chronological sequence. Due to the accuracy of the analysis, the working student recognizes the influencing variables on the duration of the elementary movements and can thus systematically develop the more rational working method. The extensive breakdown of the movements, however, requires a corresponding amount of work for the preparation of the analysis, so that the method is mainly used in large-scale and mass production with short work cycles. All time values ​​used in the WORK-FACTOR basic procedure are given in WORK-FACTOR time units, with one unit corresponding to a ten-thousandth of a minute (1 ZE = 0.0001 min). In order to open up the WORK-FACTOR system for areas of application in which analyzes using the basic method are uneconomical, two further WORK-FACTOR methods were developed from the basic method. "
