English title: The principle of comparative time studies in forest work.

The origins of time study has been in the need to streamline industrial work. One of the differences between industrial and forest work is that in forest work the working conditions are subject to continuous changes. The work is also strenuous, and physical strength may come into its own in addition to skill. For these reasons, the product of a worker per time unit varies in forest work much more than in industrial work.

In industrial time studies, determination of working tempo is, besides measurement of working time, vital when calculating the normal work performance. In the Northern Countries, it has been concluded that it is impossible to determine the working tempo of a forest worker. A so-called comparative time study in which a study is made of the work performances of the same workers at different jobs and in different conditions so that the measured working times are directly comparative. Also, the requirements made for the extension of time study material are considerably greater than in Central European time studies. It is believed that the workers subjected to time studies must be observed for at least a week in each kind of work studied if the results are to be considered reliable.

The Silva Fennica issue 61 was published in honour of professor Eino Saari‘s 60th birthday.
