Care in Applying New Theories.
The manual worker's energies are so absorbed in the physical tasks that he is annoyed by any suggestion to change his method. If he were given the position at a desk he would probably be interested in the progressive schemes for betterment of methods of work or management of business.
Bearing this state of affairs in mind, it behooves the progressive man to approach the problem of applying his theories in a very careful manner. He must realize that the men in various parts of the work are under stress of every day's requirements that makes it very difficult to intelligently take up any new scheme of procedure. Many an ideal doctrine is a beautiful thing in theory but of little value if its introduction requires an immense but unavailable energy to put it into practise.
He must realize that it is the doing of work that counts and that the men who are doing things must not be annoyed. All plans for betterment must conform to the assimilating power of the men and must not cut off their food in time of change. In other words, the new plans should be so matched on to the old methods that the change to the new will not interrupt the production.
We have seen that the most efficient way to use man's energies is to allow him to follow habit lines of thought and action, and that the highest efficiency is reached when these habits are habits of concentration of attention and are restricted to the smallest variety of work.
