The 6M system, representing the categories of man, method, machine, material, management, and measurement, or any other system representing the relevant causes, can be applied here. In the next step, the "effective—feasible" matrix is created to determine the sequence in which the causes should be eliminated. Each cause is examined for
The proposed 4 M approach takes into account all the most important aspects involved in the manual assembly: Method, Machine, Man and Material. The final goal is to provide a means for the
