RELIEVING THE WORKER OF THE PLANNING.--The planning is taken away from the worker, not because it is something too choice, sacred or entertaining for him to do, or something which the managers desire to do themselves, but because it is best, for the workers themselves as well as the work, that the planning be done by specialists at planning. If he is expert enough to plan, the worker will be promoted to the planning department. In the meantime, he is working under the best plan that experts can devise. MASTER PLANNING A LIFE STUDY.--The best planner is he who,-- other things being equal,--is the most ingenious, the most experienced and the best observer. It is an art to observe; it requires persistent attention. The longer and the more the observer observes, the more details, and variables affecting details, he observes. The untrained observer could not expect to compete with one of special natural talent who has also been trained. It is not every man who is fitted by nature to observe closely, hence to plan. To observe is a condition precedent to visualizing. Practice in visualizing makes for increasing the faculty of constructive imagination. He with the best constructive imagination is the master planner. The art of observing is founded on a study of fundamental elements. In order that planning may be done best, previous to starting work, the entire sequence of operations must be laid out, so that the ideas of value of every element of every subdivision of the process of working may be corrected to act most efficiently in relation with each and all of the subsequent parts and events that are to follow. This planning forwards and backwards demands an equipment of time study, motion study and micro-motion study records such as can be used economically only when all the planning is done in one place, with one set of records. The planner must be able to see and control the whole problem in all of its aspects. For example,--the use that is to be made of the work after it is completed may entirely change the methods best used in doing it. Thus, the face of a brick wall that is to be plastered does not require and should not have the usual excellence of nicely ruled joints required on a face that is not to be plastered. In fact, the roughest, raggedest joints will be that quality of wall that will make the plaster adhere the best. As an example of professional observation and investigation with which no untrained observer could compete, we cite the epoch making work of Dr. Taylor in determining the most efficient speeds, feeds, cuts and shape of tools to use for the least wastefulness in cutting metals.[14]
