In the early 21st century, flowcharts were still used for describing computer algorithms. Often pseudo-code is used, which uses the common idioms of such languages without strictly adhering to the details of a particular one.

The flowchart became a popular tool for describing computer algorithms, but its popularity decreased in the 1970s, when interactive computer terminals and third-generation programming languages became common tools for computer programming, since algorithms can be expressed more concisely as source code in such languages. The original programming flowcharts of Goldstine and von Neumann can be found in their unpublished report, "Planning and coding of problems for an electronic computing instrument, Part II, Volume 1" (1947), which is reproduced in von Neumann's collected works. His contemporary account was endorsed by IBM engineers and by Goldstine's personal recollections. In 1947, ASME adopted a symbol set derived from Gilbreth's original work as the "ASME Standard: Operation and Flow Process Charts." ĭouglas Hartree in 1949 explained that Herman Goldstine and John von Neumann had developed a flowchart (originally, diagram) to plan computer programs. Graham, another 1944 graduate, Director of Formcraft Engineering at Standard Register Industrial, applied the flow process chart to information processing with his development of the multi-flow process chart, to present multiple documents and their relationships.
Mogensen began to train business people in the use of some of the tools of industrial engineering at his Work Simplification Conferences in Lake Placid, New York.Īrt Spinanger, a 1944 graduate of Mogensen's class, took the tools back to Procter and Gamble where he developed their Deliberate Methods Change Program. In the early 1930s, an industrial engineer, Allan H. The Gilbreths' tools quickly found their way into industrial engineering curricula. The first structured method for documenting process flow, the " flow process chart", was introduced by Frank and Lillian Gilbreth in the presentation "Process Charts: First Steps in Finding the One Best Way to do Work", to members of the American Society of Mechanical Engineers (ASME) in 1921. The underlying graph structure of a flowchart is a flow graph, which abstracts away node types, their contents and other ancillary information. The terms "flowchart" and "flow chart" are used interchangeably. Nassi-Shneiderman diagrams and Drakon-charts are an alternative notation for process flow.Ĭommon alternative names include: flow chart, process flowchart, functional flowchart, process map, process chart, functional process chart, business process model, process model, process flow diagram, work flow diagram, business flow diagram.

Similarly, in UML, a standard concept-modeling notation used in software development, the activity diagram, which is a type of flowchart, is just one of many different diagram types. For instance, Kaoru Ishikawa defined the flowchart as one of the seven basic tools of quality control, next to the histogram, Pareto chart, check sheet, control chart, cause-and-effect diagram, and the scatter diagram. A cross-functional flowchart allows the author to correctly locate the responsibility for performing an action or making a decision, and to show the responsibility of each organizational unit for different parts of a single process.įlowcharts represent certain aspects of processes and are usually complemented by other types of diagram. A symbol appearing in a particular part is within the control of that organizational unit. A decision is usually denoted as a diamond.Ī flowchart is described as "cross-functional" when the chart is divided into different vertical or horizontal parts, to describe the control of different organizational units.
A process step, usually called an activity, is denoted as a rectangular box.Flowcharts typically use the following main symbols: Two of the many benefits are flaws and bottlenecks may become apparent. Like other types of diagrams, they help visualize the process. Flowcharts are used to design and document simple processes or programs.
