Flow Chart

A flow chart is a pictorial representation which describes a process as a series of discrete steps and/or actions. It commonly makes use of text contained in geometric outlines (rectangles, lozenges, trapeze forms) to illustrate sections of action and uses arrows to show the direction of progression throughout the process. It was introduced as a mode of representation by Frank Gilbreth in 1921 in a presentation to the American Society of Mechanical Engineers.

Later developed by John von Neuman at Princeton University in the 1940’s flow charts have become a popular means of describing and designing computer algorithms.
