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

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.

We're all like tools. Not only like tools, we are tools, tools of Time. We're worn into grooves by Time — by our habits. In the end, these grooves are going to show whether we've been second-rate or champions, each in his way, in dispatching the affairs of every day. By choosing our habits, we determine the grooves into which Time will wear us; and these are grooves that enrich our lives and make for ease of mind, peace, happiness — achievement.

The aim of the process chart is to present information regarding existing and proposed processes in such simple form that such information can become available to and usable by the greatest possible number of people in an organization before any changes whatever are actually made, so that the special knowledge and suggestions of those in positions of minor importance can be fully utilized.
