Using a system flowchart involves following a number of symbols representing actions connected by arrows to produce a desired end result, according to the BBC. The flowchart displays how data, ideas and information flow in a system, based upon decisions that control events. Symbols simplify diagrams as they stand for the same function in any flowchart.
Lines and arrows show sequences of steps in a flowchart. The lines connect to symbols that have words in them that describe the sequence of events. An oval marks the start and end of a flowchart, according to SmartDraw. An input/output symbol is a parallelogram. A rectangle represents a process or an action like "raise prices." Diamonds indicate decisions that can branch off into many directions, based upon various option such as "black" or "white."
System flowcharts differ from data flowcharts in that a system chart shows how decisions alter the flow of information. A system flowchart is also known as a process flowchart diagram. Edraw reveals these flowcharts are used in the engineering industry when the relationships between components of a process need to be visualized. Flowcharts can be hand-drawn or done on computer. Flowcharts were used by computer programmers in the 1960s to map the logical progression of programs.
