Common Flow Chart Symbols

The Flow Chart is a result of charting a process from beginning to end. It uses symbols to represent input from various sources, sequential activities, decisions to be made, and the ouput. The following description of the common flow chart symbols will enable you to use the symbols to chart the sequence of activities in nearly any process.

 Meaning

 The arrow denotes direction of the flow of ordered events.

 

An operation is performed when some change occurs or when you do something.

 

A decision point is a point in the process where a decision is made that changes the ordered flow of events.

 The circle connects the flow chart to other related, or tangential processes.

Guidelines
for Using
the Flow Chart
  • Create a flow chart beginning with general operations on the first draft. As you look at each of the operations later, you will be able to fill in more detail.
  • Do not be concerned about defining the process specifically on the first draft.
  • Refrain from trying to fix a process until it is completely diagrammed and analyzed.
  • Review your chart. Does it show the proper flow of information or operations; sequential and simultaneous events; accurately capture what really happens; reflect all major decisions?
  • When you have the operations and decisions and the flow as it actually happens, you can begin to analyze the process to determine possible improvements, eliminating steps that are unnecessary or inefficient.
  • You can perform a highly detailed analysis of any process using the flow chart. Be sure to involve people who are actually involved in the process to get accurate perceptions.
