No definite and permanent advance is made in any kind of work, whether with materials or men, until use is made of measurement. - Frank Bunker Gilbreth

There is some confusion today as to the meaning of scientific management. This concerns itself with the nature of such management itself, with the scope or field to which such management applies, and with the aims that it desires to attain. Scientific management is simply management that is based upon actual measurement. Its skilful application is an art that must be acquired, but its fundamental principles have the exactness of scientific laws which are open to study by everyone. We have here nothing hidden or occult or secret, like the working practices of an old-time craft; we have here a science that is the result of accurately recorded, exact investigation.

Process-chart notes and information should be collected and set down in sketch form by a highly intelligent man, preferably with an engineering training and experience, but who need not necessarily have been previously familiar with the actual details of the processes. In fact, the unbiased eye of an intelligent and experienced process-chart maker usually brings better results than does the study of a less keen man with more special information regarding present practices of the processes. The mere act of investigating sufficiently to make the notes in good enough condition for the draftsman to copy invariably results in many ideas and suggestions for improvement, and all of these suggestions, good and bad, should be retained and filed together with the description of the process chart. These suggestions and proposed improvements must be later explained to others, such as boards of directors, managers and foremen, and for best results also to certain workmen and clerks who have special craft or process knowledge. To overcome the obstacles due to habit, worship of tradition and prejudice, the more intelligence shown by the process-chart recorder, the sooner hearty cooperation of all concerned will be secured. Anyone can make this form of process chart with no previous experience in making such charts, but the more experience one has in making them, the more certain standard combinations of operations, inspection and transporting can be transferred bodily to advantage to the charts of proposed processes.

There is no waste of any kind in the world that equals the waste from needless, ill-directed and ineffective motions, and their resulting unnecessary fatigue.
