Principles of Flow Chart Diagram
* Always draw the first draft using PENCIL and PAPER
* NO need to give all details,
* Draw out the main flow only
* As far as other could understand it, it's enough (it's for communication, not for display)
* Use box and arrow lines mainly. If a flow is removed in later phase, use dotted lines.
