Abstract
Two experiments are discussed. They were designed for the determination of tho best work method from the point of view of ergonomics. Methods for the detection of long term effects on the state of health are indicated. The economy of the work has been judged by comparison of the effort expended and the resulting performance. The results of these measurements are also largely influenced by the personal capabilities for the performance of the particular task by each of the subjects. An analysis of this capability is given-. Attention is also given to the difficulties of comparing work methods when the composition or the use made of the teams of subjects varies. If different groups of subjects are compared, each using their own work method, the groups may differ too much in general working capacity; if the same group applies different work methods, exporionco in using one method will be greater than with another. Adjustment of the energy expenditure to compensate- for differences in pace or quality wore not considered feasible.
