This country has been so rich in human and material resources that it is only recently that the importance of waste elimination has come to be realiz… - Frank Bunker Gilbreth

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

The Process Chart is a device for visualizing a process as a means of improving it. Every detail of a process is more or less affected by every other detail; therefore the entire process must be presented in such form that it can be visualized all at once before any changes are made in any of its subdivisions. In any subdivision of the process under examination, any changes made without due consideration of all the decisions and all the motions that precede and follow that subdivision will often be found unsuited to the ultimate plan of operation.

The first step in any great movement is to... arouse interest in the subject, to discuss the great problems involved, to outline the possible solutions, and to assign the various problems to those best fitted to undertake and handle them. The next step is to realize that all this discussion, valuable as it is, can grow into such action as it deserves, only if measurement is insisted upon from the very beginning of making the investigations outlined, if the records of measurement are in such form that they can be used by those who did not make them, that skill and experience may thus be transferred, and if the results of the measurements are incorporated into actual and universal practice as soon as they are properly synthesized into practical methods of least waste. The world has come to realize the truth of this as applied to material things. The day of standardization of materials and of machines is far advanced, and is daily progressing; but such has been rarely the case with measurement as applied to the human element.
