SYNTHESIST AN INVENTOR.—­The valuable inventions referred to as the result of measurement are the work of the synthetic mind.  It discovers new, better methods of doing work, and this results in the invention of better means, such as tools or equipment.

For example,—­in the field of Bricklaying, the Non-stooping Scaffold, the Packet and the Fountain Trowel were not invented until the analysis of bricklaying was made, and the synthesis of the chosen elements into standard methods made plain the need and specifications for new equipment.

RELATION OF INVENTION TO SCIENTIFIC MANAGEMENT IMPORTANT.—­There has been much discussion as to the relation of Invention to Scientific Management.  It has been claimed by many otherwise able authorities that many results claimed as due to Scientific Management are really the results of new machinery, tools or equipment that have been invented.[9] Scientific Management certainly can lay no claim to credit for efficiency which comes through inventions neither suggested nor determined by it.  But the inventions from the results of which Scientific Management is said to have borrowed credit are usually, like the bricklaying inventions cited, not only direct results of Scientific Management, but probably would not have sprung from any other source for years to come.

SYNTHESIST A DISCOVERER OF LAWS.—­It is the synthetic type of mind that discovers the laws.  For example—­it was Dr. Taylor, with the aid of a few of his specially trained co-workers, who discovered the following governing laws: 

    1. law of no ratio between the foot-pounds of work done and
       the fatigue caused in different kinds of work.
    2. law of percentage of rest for overcoming fatigue.
    3. law of classification of work according to percentage of
       fatigue caused.
    4. laws for making high-speed steel.
    5. laws relating to cutting metals.
    6. laws that will predict the right speed, feed and cut on
       metals for the greatest output.
    7. laws for predicting maximum quantity of output that a man
       can achieve and thrive.
    8. laws for determining the selection of the men best suited
       for the work.

SYNTHESIST AN ADVISER ON INTRODUCTION OF NEW METHODS.—­Having constructed the standard tasks or standard methods which are new, the synthesist must remember to introduce his new task or method with as few new variables as possible.  He should so present it that all the old knowledge will come out to meet the new, that all the brain paths that have already been made will be utilized, and that the new path will lead out from paths which are well known and well traveled.

INTRODUCE WITH AS FEW NEW VARIABLES AS POSSIBLE.—­The greatest speed in learning a new method will be attained by introducing it with as few new variables as possible.
