The Methods of Fatigue Study.

The methods used must rest on a scientific basis. These methods are the same for the expert and for the man making his first attack on the problem. They are as follows:

1. Record present practice, make an accurate and complete account in writing of what is actually being done.

2. Decide in what sequence things are to be measured, and put them in such shape that they can be measured.

3. Apply accurate measurement.

4. Determine standards synthetically from the measurement, and make such changes in practice as will make it conform to the standard.

5. Compare the new standard practice with the old practice. Determine exactly what improvements have been made, in order to be able to predict the line along which new improvements must lie.

This is the standard method of attack of measured functional management. It can be the more successfully applied to fatigue study in that the results can be checked at every point by the results of motion study, which bear a constant relation to them.
