Manual Input: Data or information into a system 18. Flow lines to an alternate process block is usually dashed. Alternate Process: An alternate to the normal process step. Delay: Any delay period that is part of a process 11. Off-page Connector: An off-page connector is used when the target is on another page. On-page Connector: Pairs of on-page connecter are used to replace long lines on a flowchart page. Predefined Process: Shows named process which is defined elsewhere. Annotation / Comment: Indicates additional information regarding a step in a process.
Input / Output: Indicates the process of inputting or outputting external data. This is commonly a yes/no or true/false question. Decision: Shows a step that decides the next step in a process. This is the most common component of a flowchart. Terminal: Indicates the beginning or end of a flowchart 3.

For a full list of flowchart symbols, read our Guide on Flowchart Symbolsġ. In general, flowcharts flow from top to bottom and left to right. Afterwards, the International Organization for Standardization (ISO) adopted the ANSI symbols in 1970. Specifically, the American National Standards Institute (ANSI) set standards for flowcharts and their symbols in the 1960s. However, if you want to get technical and precise, there are preset rules and standards you can follow. In fact, a simple flowchart, constructed with just rectangular blocks and flowlines, can already get most jobs done.
As such, in most cases, you don’t need to worry too much about the standards and rules of all the flow chart symbols. What is a Flowchart used for?įlowchart is a very versatile tool that can be used to:įlowchart is a very intuitive method to describe processes. Nowadays, flow chart is an important productivity tool, serving employees in various industries and functions. In the year 1949, flowchart began to be used for planning computer programs and quickly became one of the most popular tools in designing computer algorithms and programs. In 1947, ASME adopted a symbol set derived from Gilbreth’s original work as the “ASME Standard: Operation and Flow Process Charts.” Participants from this conference such as Art Spinanger and Ben Grahamthen began to use flowchart in their respective fields, which helped propagate the usage of flowchart. Mogensen, an industrial engineer trained some participants in his Work Simplification Conferences in New York. In 1921, the couple presented the graphic-based method in a presentation titled: “Process Charts: First Steps in Finding the One Best Way to do Work”, to members of the American Society of Mechanical Engineers (ASME).Īfter that, in 1930s, Allan H. It is not clear who was the true inventor of flowcharts, but the first standardized documentation on flow chart was first introduced by Frank and Lillian Gilbreth.
