5) General Guideline for Flow Chart (Process Flow Diagram) making:

 → The process need start from top to down, from left to right. 
 → Flow Chart (Process Flow Diagram) graph size needs to be the same.
 → The start symbol only appears once, but end symbol can use more.
 → There is only one arrow path graph for the same path.
 → The line should avoid the cross, if need crossed should be used across the graph.
