The article analyses the efficiency of forest work, and the use of time and motion study methods in forest work. Forest work can be characterized by little use of machinery. It cannot be repeated as orderly as industrial work. This affects also how the efficiency of the work can be measured. Only parts of the work can be timed. The study takes making of piled wood as an example. First are determined the standard times for the work moments. They include the time used to prepare the piled wood, and the waste time. It is concluded that forest work can be standardized with the methods of work analysis.

The fellings of small timber have been expanded from seasonal to full-year operation in many areas. A time and motion study was conducted on the felling of pulpwood in different times of the year in seven felling sites in the northernmost Finland. The work was payed per one pulpwood bolt. The output of a one-man teams was larger than 2-6-man teams. Teams of even numbers were more effective than teams of uneven numbers. One-man teams were more popular during summer. The output was largest during the summer. In the late summer the results decrease, because barking of trees becomes more difficult. Shortening of daylight hours begin to shorten the workdays in the autumn. In December, the average working days are about 6 hours. Snow and low temperatures make logging and barking more difficult during the winter. The output was lowest in January, despite that work days are 1 ½ hours longer than in December. It is concluded that pulpwood fellings should be avoided from December to March 15. If the fellings are necessary, the wage system should be changed more flexible than at present. The size of cutter’s lots should be adjusted so, that work periods are not too short. Sufficiently big lots save time spent on travelling between the sites and villages.
