Flowchart Rules

  • Do not chart every detail, otherwise, the flowchart will only be a graphic representation of all the steps of the corresponding program.
  • Use common statement that are easy to understand for words within flowchart symbols.
  • Be consistent in using names and variable in the flowcharts.
  • Go from left to right and top to bottom in constructing flowchart.
  • Keep the flowchart as simple a possible.
