Flow Chart

 Flow chart a diagram is use to graphically represent program logic, algorithm and workflow model because A picture is worth a thousand words. Flow chart is easy way to write down programming logic using various symbols which help programming easily convert these symbols of logic into its equivalent code in any language. Flow chart decreases software development process.


The first structured method for document process flow, the "flow process chart", was introduced by Frank and Lillian Gilbreth to members of the American Society of Mechanical Engineers (ASME) in 1921 in the presentation "Process Charts: First Steps in Finding the One Best Way to do Work". The Gilbreths' tools quickly found their way into industrial engineering curricula. In the early 1930s, an industrial engineer, Allan H. Mogensen began training business people in the use of some of the tools of industrial engineering at his Work Simplification Conferences in Lake Placid, New York.
