corrected for flow chart

A simple flowchart for what to do if a lamp doesn't work

A flowchart (also spelled flow-chart and flow chart) is a schematic representation of a process. They are commonly used in business/economic presentations to help the audience visualize the content better, or to find flaws in the process.

Part of Seven tools of quality (Quality improvement tools that include the histogram, Pareto chart, check sheet, control chart, cause-and-effect diagram, flowchart, and scatter diagram.) see

Examples include instructions for a bicycle's assembly, an attorney outlining a case's timeline, diagram of an automobile plant's work flow, the decisions to be taken on a tax form, et cetera.

Generally the start point, end points, inputs, outputs, possible paths and the decisions that lead to these possible paths are included.

Many humorous flowcharts exist, e.g. one that outlines how to pass the blame if something goes wrong.

Flow-charts can be created by hand or manually in most office software, but lately specialized diagram drawing software has emerged that can also be used for the purpose, such as Visio, OpenOffice.org Draw, Dia, SmartDraw, and OmniGraffle.

Programs have been written to create flowcharts directly from computer program source.

History of use

Flowcharts were used historically in electronic data processing to represent the conditional logic of computer programs. With the emergence of structured programming and structured design in the 1980s, visual formalisms like data flow diagrams and structure charts begun to supplant the use of flowcharts. With the widespread adoption of such ALGOL-like computer languages as Pascal, textual models like pseudocode have been used more often to represent algorithms. In the 1990s Unified Modeling Language began to synthesize and codify these modeling techniques.

Creating flowcharts on a computer

There are various packages for creating flowcharts, according to different standards. The most common is UML, for which there are abundant packages for various platforms. See UML article for list. The creation of simple flowcharts on a computer is fairly easy with any vector-based drawing program, but Microsoft Word (versions 97 through 2003) and OpenOffice.org (Draw-module or CustomShapes) both have specialized tools for making consistent charts.

When in Word, enable the Drawing toolbar and click Autoshapes then Flowcharts and finally on the appropriate shape you would like. Right-click on a shape and then click Add Text to do so. The Arrow or Line tool is used to manually draw links.

When in OpenOffice.org, enable the Drawing toolbar which has a flow-out menu for Flowcharts since version 2.0, which can do roughly the same as Word.

When in OpenOffice.org Draw, enable the Flowchart palette and click a shape to add it in. Double-clicking a shape will add text to it within appropriate boundaries. Connections can be automatically made between shapes using Connectors and Glue Points - click on the Connector arrow to see a selection of them before dragging from a Glue Point on a shape to another. Draw will maintain the link and automatically redraw the connector if you resize or move any shape.
