Well-drawn flow charts are easy to read. Here are a few rules for well-drawn flow charts:
Every flowchart has a START symbol and a STOP symbol.
The flow of sequence is generally from the top of the page to the bottom of the page. This
can vary with loops which need to flow back to an entry point.
Use arrow-heads on connectors where flow direction may not be obvious.
There is only one flow chart per page.
A page should have a page number and a title.
A flow chart on one page should not break and jump to another page.
A flow chart should have no more than around 15 symbols (not including START and
STOP).
